  • 1939 – Sigmund Freud, Austrian neurologist and psychiatrist (b. 1856).

Sigmund Freud

Sigmund Freud (born Sigismund Schlomo Freud; 06 May 1856 to 23 September 1939) was an Austrian neurologist and the founder of psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient and a psychoanalyst.

Freud was born to Galician Jewish parents in the Moravian town of Freiberg, in the Austrian Empire. He qualified as a doctor of medicine in 1881 at the University of Vienna. Upon completing his habilitation in 1885, he was appointed a docent in neuropathology and became an affiliated professor in 1902. Freud lived and worked in Vienna, having set up his clinical practice there in 1886. In 1938, Freud left Austria to escape Nazi persecution. He died in exile in the United Kingdom in 1939.

In founding psychoanalysis, Freud developed therapeutic techniques such as the use of free association and discovered transference, establishing its central role in the analytic process. Freud’s redefinition of sexuality to include its infantile forms led him to formulate the Oedipus complex as the central tenet of psychoanalytical theory. His analysis of dreams as wish-fulfilments provided him with models for the clinical analysis of symptom formation and the underlying mechanisms of repression. On this basis, Freud elaborated his theory of the unconscious and went on to develop a model of psychic structure comprising id, ego and super-ego. Freud postulated the existence of libido, sexualised energy with which mental processes and structures are invested and which generates erotic attachments, and a death drive, the source of compulsive repetition, hate, aggression, and neurotic guilt. In his later works, Freud developed a wide-ranging interpretation and critique of religion and culture.

Though in overall decline as a diagnostic and clinical practice, psychoanalysis remains influential within psychology, psychiatry, and psychotherapy, and across the humanities. It thus continues to generate extensive and highly contested debate concerning its therapeutic efficacy, its scientific status, and whether it advances or hinders the feminist cause. Nonetheless, Freud’s work has suffused contemporary Western thought and popular culture. W.H. Auden’s 1940 poetic tribute to Freud describes him as having created “a whole climate of opinion / under whom we conduct our different lives”.

What is Child Psychopathology?

Introduction

Child psychopathology refers to the scientific study of mental disorders in children and adolescents.

Oppositional defiant disorder, attention-deficit hyperactivity disorder, and autism spectrum disorder are examples of psychopathology that are typically first diagnosed during childhood. Mental health providers who work with children and adolescents are informed by research in developmental psychology, clinical child psychology, and family systems. Lists of child and adult mental disorders can be found in the International Statistical Classification of Diseases and Related Health Problems, 10th Edition (ICD-10), published by the World Health Organisation (WHO) and in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), published by the American Psychiatric Association (APA). In addition, the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (DC) is used in assessing mental health and developmental disorders in children up to age five.

Causes

The aetiology of child psychopathology has many explanations which differ from case to case. Many psychopathological disorders in children involve genetic and physiological mechanisms, though there are still many without any physical grounds. It is absolutely imperative that multiple sources of data be gathered. Diagnosing the psychopathology of children is daunting. It is influenced by development and contest, in addition to the traditional sources. Interviews with parents about school, etc., are inadequate. Either reports from teachers or direct observation by the professional are critical. (author, Robert B. Bloom, Ph.D.) The disorders with physical or biological mechanisms are easier to diagnose in children and are often diagnosed earlier in childhood. However, there are some disorders, no matter the mechanisms, that are not identified until adulthood. There is also reason to believe that there is co-morbidity of disorders, in that if one disorder is present, there is often another.

Stress

Emotional stress or trauma in the parent-child relationship tends to be a cause of child psychopathology. First seen in infants, separation anxiety in root of parental-child stress may lay the foundations for future disorders in children. There is a direct correlation between maternal stress and child stress that is factored in both throughout adolescent development. In a situation where the mother is absent, any primary caregiver to the child could be seen as the “maternal” relationship. Essentially, the child would bond with the primary caregiver, and may exude some personality traits of the caregiver.

In studies of child in two age groups of pregnancy to five years, and fifteen years and twenty years, Raposa and colleagues (2011) studied the impact of psychopathology in the child-maternal relationship and how not only the mothers stress affected the child, but the child’s stress affected the mother. Historically, it was believed that mothers who suffered from post partum depression might be the reason their child suffers from mental disorders both earlier and later in development. However this correlation was found to not only reflect maternal depression on child psychopathology, but also child psychopathology could reflect on maternal depression.

Children with a predisposition to psychopathology may cause higher stress in the relationship with their mother, and mothers who suffer from psychopathology may also cause higher stress in the relationship with their child. Child psychopathology creates stress in parenting which may increase the severity of the psychopathology within the child. Together, these factors push and pull the relationship thus causing higher levels of depression, ADHD, defiant disorder, learning disabilities, and pervasive developmental disorder in both the mother and the child. The outline and summary of this study is found below:

In looking at child-related stress, the number of past child mental health diagnoses significantly predicted a higher number of acute stressors for mothers as well as more chronic stress in the mother-child relationship at age 15. These increased levels of maternal stress and mother-child relationship stress at age 15 then predicted higher levels of maternal depression when the youth were 20 years old.

Looking more closely at the data, the authors found that it was the chronic stress in the mother-child relationship and the child-related acute stressors that were the linchpins between child psychopathology and maternal depression. The stress is what fuelled the fires between mother and child mental health. Going one step further, the researchers found that youth with a history of more than one diagnosis as well as youth that had externalizing disorders (e.g. conduct disorder) had the highest number of child-related stressors and the highest levels of mother-child stress. Again, all of the findings held up when other potentially stressful variables, such as economic worries and past maternal depression, were controlled for.

Additionally, siblings- both older and younger and of both genders, can be factored into the aetiology and development of child psychopathology. In a longitudinal study of maternal depression and older male child depression and antisocial behaviours on younger siblings adolescent mental health outcome. The study factored in ineffective parenting and sibling conflicts such as sibling rivalry. Younger female siblings were more directly affected by maternal depression and older brother depression and anti social behaviours when the indirect effects were not place, in comparison to younger male siblings who showed no such comparison. However, if an older brother were anti-social, the younger child – female or male would exude higher anti-social behaviours. In the presence of a sibling conflict, anti social behaviour was more influential on younger male children than younger female children. Female children were more sensitive to pathological familial environments, thus showing that in a high-stress environment with both maternal depression and older- male sibling depression and anti social behaviour, there is a higher risk of female children developing psychopathological disorders. This was a small study, and more research needs to be done especially with older female children, paternal relationships, maternal-paternal-child stress relationships, and/or caregiver-child stress relationships if the child is orphaned or not being raised by the biological child to reach a conclusive child-parent stress model on the effects of familial and environmental pathology on the child’s development.

Temperament

The child-parent stress and development is only one hypothesis for the aetiology of child psychopathology. Other experts believe that child temperament is a large factor in the development of child psychopathology. High susceptibility to child psychopathology is marked by low levels of effortful control and high levels of emotionality and neuroticism. Parental divorce is often a large factor in childhood depression and other psychopathological disorders. This is more so when the divorce involves a long-drawn separation and one parent bad-mouthing the other. That is not to say that divorce will lead to psychopathological disorders, there are also other factors such as temperament, trauma, and other negative life events (e.g. death, sudden moving of home, physical or sexual abuse), genetics, environment, and nurture that correlate to the onset of a disorder. Research has also shown that child maltreatment may increase risk for various forms of psychopathology as it increases threat sensitivity, decreases responsivity to reward, and causes deficits in emotion recognition and understanding.

Found in “The Role of Temperament in the Etiology of Child Psychopathology”, a model for the aetiology of child psychopathology by Vasey and Dadds (2001) proposed that the four things that are important to the development of psychopathological disorders is:

  1. Biological factors: hormones, genetics, and neurotransmitters;
  2. Psychological: self-esteem, coping skills, and cognitive issues;
  3. Social factors: family rearing, negative learning experiences, and stress; and
  4. Child’s temperament.

Using an array of neurological scans and exams, psychological evaluations, family medical history, and observing the child in daily factors can help the physician find the aetiology of the psychopathological disorder to help release the child of the symptoms through therapy, medication use, social skills training, and life style changes.

Child psychopathology can cause separation anxiety from parents, attention deficit disorders in children, sleep disorders in children, aggression with both peers and adults, night terrors, extreme anxiety, anti social behaviour, depression symptoms, aloof attitude, sensitive emotions, and rebellious behaviour that are not in line of typical childhood development. Aggression is found to manifest in children before five years of age, and early stress and aggression in the parental-child relationship correlates with the manifestation of aggression. Aggression in children causes problematic peer relationships, difficulty adjusting, and coping problems. Children who fail to overcome acceptable ways of coping and emotion expression are put on tract for psychopathological disorders and violent and anti social behaviours into adolescence and adulthood. There is a higher rate of substance abuse in these children with coping and aggression issues, and causes a cycle of emotional instability and manifestation psychopathological disorders.

Neurology and Aetiology

Borderline personality disorder (BPD) is one of many psychopathology disorders a child can suffer from. In the neurobiological scheme, borderline personality disorder may have effects on the left amygdala. In a 2003 study of BPD patients versus control patients, when faced with expressions that were happy, sad, or fearful BPD patients showed significantly more activation versus control patients. In neutral faces, BPD patients attributed negative qualities to these faces. As stated by Gabbard, an experimenter in this study:

“A hyperactive amygdala may be involved in the predisposition to be hyper vigilant and over reactive to relatively benign emotional expressions. Misreading neutral faces is clearly related to transference misreadings that occur in psychotherapy and the creation of bad object experiences linked with projective identification.”

Also linked to BPD, is the presence of serotonin transporter (5-HTT) in a short allele demonstrated larger amygdala neuronal activity when presented with fearful stimuli as in comparison to individuals with a long allele of 5-HTT. As found in the Dunedin Longitudinal Study a short allele of 5-HTT predisposes the person to have hyperactivity in the amygdala in response to trauma, and thus moderated the impact of stressful life events leading to a higher risk of depression and suicidal idealities. These same qualities were not observed in individuals with long alleles of 5-HTT. However, the environment the child is in can change in impact of this gene, proving that correct treatment, intensive social support, and a healthy and nurturing environment can modify genetic vulnerability.

Possibly the most studied or documented of the child psychopathologies is attention deficit hyperactivity disorder (ADHD) which is marked with learning disabilities, mood disorders, and/or aggression. Though believed to be over diagnosed, ADHD is highly comorbid for other disorders such as depression and obsessive compulsive disorder. In studies of the prefrontal cortex in ADHD children, which is responsible for the regulation of behaviour, cognition, and attention; and in the dopamine system there has been identified a hidden genetic polymorphisms. More specific, the 7-repeat allele of the dopamine D4 receptor gene, responsible for inhibited prefrontal cortex cognition and less efficient receptors, causes more externalised behaviours such as aggression since the child has trouble “thinking through” seemingly ordinary and at level childhood tasks.

Agenesis of the Corpus Callosum and Aetiology

Agenesis of the corpus callosum (ACC) is used to determine the frequency of social and behavioural problems in children with a prevalence rate of about 2-3%. ACC is described as a defect in the brain where the 200 million axons that make the corpus collosum are either completely absent, or partially gone. In many cases, the anterior commissure is still present to allow for the passing of information from one cerebral hemisphere to the other. The children are of normal intelligence level. For younger children, ages two to five, Agenesis of the corpus callosum causes problems in sleep. Sleep is critical for development in children, and lack of sleep can set the grounds for a manifestation of psychopathological disorders. In children ages six to eleven, ACC showed manifestation in problems with social function, thought, attention, and somatic grievances. In comparison, of children with autism, children with ACC showed less impairment on almost all scales such as anxiety and depression, attention, abnormal thoughts, and social function versus autistic children. However, a small percentage of children with ACC showed traits that may lead to the diagnosis of autism in the areas of social communications and social interactions but do not show the same symptoms of autism in the repetitive and restricted behaviours category. The difficulties from ACC may lead to the aetiology of child psychopathological disorders, such as depression or ADHD and manifest many autistic-like disorders that can cause future psychological disorders in later adolescence. The aetiology of child psychopathology is a multi-factor path. A slew of factors must be taken into account before diagnosis of a disorder.

The child’s genetics, environment, temperament, past medical history, family medical history, prevalence of symptoms and neuro-anatomical structures are all factors that should be considered when diagnosing a child with a psychopathological disorder. Thousands of children each year are misdiagnosed and put on the wrong treatment, which may result in the manifestation of other disorders the child would have not have gotten else wise. There are hundreds of causes of psychopathological disorders, and each one manifests at different ages and stages in child development and can come out due to trauma and stress. Some disorders may “disappear” and reappear in the presence of a trauma, depression, or stress similar to the one that brought the disorder out in the child in the beginning.

Treatment

It is estimated that 5% of children under the age of eight suffer from a psychopathology disorder. Girls more frequently manifested disorders than boys in similar situations. By age sixteen about thirty percent of children will have fit the criteria for at least one psychopathology disorder. Only a small number of these children receive treatment for their disorder. Anxiety and depression disorders in children- whether noted or un-noted, are found to be a precursor for similar episodes in adulthood. Usually a large stressor similar to the one the person experienced in childhood brings out the anxiety or depression in adulthood.

Multifinality refers to the idea that two children can react to same stressful event quite differently, and may display divergent types of problem behaviour. Psychopathological disorders are extremely situational- having to take into account the child, the genetics, the environment, the stressor, and many other factors to tailor the best type of treatment to relieve the child of the psychopathology symptoms.

Many child psychopathology disorders are treated with control medications prescribed by a paediatrician or psychiatrist. After extensive evaluation of the child through school visits, by psychologists and physicians, a medication can be prescribed. A patient may need to go through several trials of medicines to find the best fit, as many cause uncomfortable and undesired side effects – such as dry mouth or suicidal thoughts can occur. There are many classes of drugs a physician can choose from and they are: psychostimulants, beta blockers, atypical antipsychotics, lithium, alpha-2 agonists, traditional antipsychotics, SSRIs, and anticonvulsant mood- stabilisers. Given the multifinality of psychopathological disorders, two children may be on the same medication for two completely different disorders, or have the same disorder and be taking two completely different medications.

ADHD is the most successfully treated disorder of child psychopathology, and the medications used have a high- abuse rate especially among college-aged students. Psycho stimulants such as Ritalin, amphetamine- related stimulant drugs: e.g. Adderall, and antidepressants such as Wellbutrin have been successfully used to treat ADHD with a 78% success rate. Many of these drug treatment options are paired with behavioural treatment such as therapy or social skills lessons.

Lithium has shown to be extremely effective in treating ADHD and bipolar disorder. Lithium treats both mania and depression and helps prevent relapse. The mechanism of lithium include the inhibition of GSK-3, it is a glutamate antagonism at NMDA receptors that together make lithium a neuroprotective medicine. The drug relieves bipolar symptoms, aggressiveness and irritability. Lithium has many, many side effects and requires weekly blood tests to tests for toxicity of the drug.

Medications that act on cell membrane ion channels, are GABA inhibitory neurotransmission, and also inhibit excitatory glutamate transmission have shown to be extremely effective in treating an array of child psychopathological disorders. Pharmaceutical companies are in the process of creating new drugs and improving those on the market to help avoid negative and possibly life altering short term and long term side effects, making drugs more safe to use in younger children and over long periods of time during adolescent development.

Psychotherapy Treatments for Common Psychological Disorders in Children

Some psychological disorders commonly found in children include depression, anxiety, and conduct disorder. For adolescents with depression, a combination of antidepressants and cognitive-behavioural or interpersonal psychotherapy is recommended, in contrast there is not much evidence for the efficacy of antidepressants in children under 12 years of age, therefore a combination of parent training and cognitive-behavioural psychotherapy is recommended. For children and adolescents suffering from anxiety disorders, cognitive-behavioural therapy in combination with exposure-based techniques is a highly recommended and evidence-based treatment. Research suggests that children and adolescents with conduct disorder or disruptive behaviour may benefit from psychotherapy that includes both a behavioural component and parental involvement.

Future of Child Psychopathology

The future of child psychopathology-aetiology and treatment has a two-way path. While many professionals agree that many children who suffer from a disorder do not receive proper treatment, at the rate of 5-15% that receive treatment leaving many children in the dark. In the same boat are the physicians who also say that not only do more of these disorders need to be recognised in children and treated properly, but also even those children who show some qualifying symptoms of a disorder but not to the degree of diagnosis should also receive treatment and therapy to avoid the manifestation of the disorder. By treating children even with slight degrees of a psychopathological disorder, children can show improvements in their relationships with peers, family, and teachers and also improvements in school, mental health, and personal development. Many physicians believe the best prevention and help starts in the home and the school of the child, before physicians and psychologists are contacted.

So while there is more awareness of child psychopathological disorders and more research to prevent and effectively treat these disorders to maintain healthy emotional health in children, there is also a negative factor in that parents, schools, and psychologists may be more sensitive and therefore over-diagnose children with these disorders. Mental health professionals and pharmaceutical marketing companies need to be cautious of making disorders too readily diagnosed and treated with medications.

Child psychopathology is a real thing that thousands of children suffer from. While hundreds of children are diagnosed with a new disorder daily, researchers are developing new strategies to beat these disorders in children to allow all children the right to a happy and healthy childhood. With further education on the symptoms and implications of child psychopathology, psychologists and physicians will improve their accuracy in diagnosing children – giving the right diagnosis and discovering the most helpful treatment and therapies for children.

The current trend in the US is to understand child psychopathology from a systems based perspective called developmental psychopathology. Recent emphasis has also been on understanding psychological disorders from a relational perspective with attention also given to neurobiology. Practitioners who follow attachment theory believe that early attachment experiences of children can promote adaptive strategies or lay the groundwork for maladaptive ways of coping which can later lead to mental health disorders.

Research and clinical work on child psychopathology tends to fall under several main areas: aetiology, epidemiology, diagnosis, assessment, and treatment.

Parents are considered a reliable source of information because they spend more time with children than any other adult. A child’s psychopathology can be connected to parental behaviours. Clinicians and researchers have experienced problems with children’s self-reports and rely on adults to provide the information.

What is the Diathesis-Stress Model?

Introduction

The diathesis-stress model, also known as the vulnerability-stress model, is a psychological theory that attempts to explain a disorder, or its trajectory, as the result of an interaction between a predispositional vulnerability, the diathesis, and a stress caused by life experiences. The term diathesis derives from the Greek term (διάθεσις) for a predisposition, or sensibility. A diathesis can take the form of genetic, psychological, biological, or situational factors. A large range of differences exists among individuals’ vulnerabilities to the development of a disorder.

The diathesis, or predisposition, interacts with the individual’s subsequent stress response. Stress is a life event or series of events that disrupts a person’s psychological equilibrium and may catalyse the development of a disorder. Thus the diathesis-stress model serves to explore how biological or genetic traits (diatheses) interact with environmental influences (stressors) to produce disorders such as depression, anxiety, or schizophrenia. The diathesis-stress model asserts that if the combination of the predisposition and the stress exceeds a threshold, the person will develop a disorder. The use of the term diathesis in medicine and in the specialty of psychiatry dates back to the 1800s; however, the diathesis-stress model was not introduced and used to describe the development of psychopathology until it was applied to explaining schizophrenia in the 1960s by Paul Meehl.

The diathesis-stress model is used in many fields of psychology, specifically for studying the development of psychopathology. It is useful for the purposes of understanding the interplay of nature and nurture in the susceptibility to psychological disorders throughout the lifespan. Diathesis-stress models can also assist in determining who will develop a disorder and who will not. For example, in the context of depression, the diathesis-stress model can help explain why Person A may become depressed while Person B does not, even when exposed to the same stressors. More recently, the diathesis-stress model has been used to explain why some individuals are more at risk for developing a disorder than others. For example, children who have a family history of depression are generally more vulnerable to developing a depressive disorder themselves. A child who has a family history of depression and who has been exposed to a particular stressor, such as exclusion or rejection by his or her peers, would be more likely to develop depression than a child with a family history of depression that has an otherwise positive social network of peers. The diathesis-stress model has also served as useful in explaining other poor (but non-clinical) developmental outcomes.

Protective factors, such as positive social networks or high self-esteem, can counteract the effects of stressors and prevent or curb the effects of disorder. Many psychological disorders have a window of vulnerability, during which time an individual is more likely to develop disorder than others. Diathesis-stress models are often conceptualised as multi-causal developmental models, which propose that multiple risk factors over the course of development interact with stressors and protective factors contributing to normal development or psychopathology. The differential susceptibility hypothesis is a recent theory that has stemmed from the diathesis-stress model.

Diathesis

The term diathesis is synonymous with vulnerability, and variants such as “vulnerability-stress” are common within psychology. A vulnerability makes it more or less likely that an individual will succumb to the development of psychopathology if a certain stress is encountered. Diatheses are considered inherent within the individual and are typically conceptualised as being stable, but not unchangeable, over the lifespan. They are also often considered latent (i.e. dormant), because they are harder to recognise unless provoked by stressors.

Diatheses are understood to include genetic, biological, physiological, cognitive, and personality-related factors. Some examples of diatheses include genetic factors, such as abnormalities in some genes or variations in multiple genes that interact to increase vulnerability. Other diatheses include early life experiences such as the loss of a parent, or high neuroticism. Diatheses can also be conceptualised as situational factors, such as low socio-economic status or having a parent with depression.

Stress

Stress can be conceptualised as a life event that disrupts the equilibrium of a person’s life. For instance, a person may be vulnerable to become depressed, but will not develop depression unless they are exposed to a specific stress, which may trigger a depressive disorder. Stressors can take the form of a discrete event, such the divorce of parents or a death in the family, or can be more chronic factors such as having a long-term illness, or ongoing marital problems. Stresses can also be related to more daily hassles such as school assignment deadlines. This also parallels the popular (and engineering) usage of stress, but note that some literature defines stress as the response to stressors, especially where usage in biology influences neuroscience.

It has been long recognised that psychological stress plays a significant role in understanding how psychopathology develops in individuals. However, psychologists have also identified that not all individuals who are stressed, or go through stressful life events, develop a psychological disorder. To understand this, theorists and researchers explored other factors that affect the development of a disorder and proposed that some individuals under stress develop a disorder and others do not. As such, some individuals are more vulnerable than others to develop a disorder once stress has been introduced. This led to the formulation of the diathesis-stress model.

Genetics

Sensory processing sensitivity (SPS) is a temperamental or personality trait involving “an increased sensitivity of the central nervous system and a deeper cognitive processing of physical, social and emotional stimuli”. The trait is characterised by “a tendency to ‘pause to check’ in novel situations, greater sensitivity to subtle stimuli, and the engagement of deeper cognitive processing strategies for employing coping actions, all of which is driven by heightened emotional reactivity, both positive and negative”.

Sensory processing sensitivity captures sensitivity to environment in a heritable, evolutionary-conserved trait, associated with increased information processing in the brain. Moderating sensitivity to environments in a for-better-and-for-worse fashion. Interaction with negative experiences increases risk for psychopathology. Whereas interaction with positive experiences (including interventions), increases positive outcomes. Mast cells are long-lived tissue-resident cells with an important role in many inflammatory settings including host defence to parasitic infection and in allergic reactions. Stress is known to be a mast cell activator.

There is evidence that children exposed to prenatal stress may experience resilience driven by epigenome-wide interactions.” Early life stress interactions with the epigenome show potential mechanisms driving vulnerability towards psychiatric illness. ancestral stress alters lifetime mental health trajectories via epigenetic regulation.

Carriers of congenital adrenal hyperplasia have a predeposition to stress, due to the unique nature of this gene. True rates of prevalence are not known but common genetic variants of the human Steroid 21-Hydroxylase Gene (CYP21A2) are related to differences in circulating hormone levels in the population.

Psychological distress is a known feature of generalised joint hypermobility (gJHM), as well as of its most common syndromic presentation, namely Ehlers-Danlos syndrome, hypermobility type (a.k.a. joint hypermobility syndrome – JHS/EDS-HT), and significantly contributes to the quality of life of affected individuals. Interestingly, in addition to the confirmation of a tight link between anxiety and gJHM, preliminary connections with depression, attention deficit (and hyperactivity) disorder, autism spectrum disorders, and obsessive-compulsive personality disorder were also found.

Protective Factors

Protective factors, while not an inherent component of the diathesis-stress model, are of importance when considering the interaction of diatheses and stress. Protective factors can mitigate or provide a buffer against the effects of major stressors by providing an individual with developmentally adaptive outlets to deal with stress. Examples of protective factors include a positive parent-child attachment relationship, a supportive peer network, and individual social and emotional competence.

Throughout the Lifespan

Many models of psychopathology generally suggest that all people have some level of vulnerability towards certain mental disorders, but posit a large range of individual differences in the point at which a person will develop a certain disorder. For example, an individual with personality traits that tend to promote relationships such as extroversion and agreeableness may engender strong social support, which may later serve as a protective factor when experiencing stressors or losses that may delay or prevent the development of depression. Conversely, an individual who finds it difficult to develop and maintain supportive relationships may be more vulnerable to developing depression following a job loss because they do not have protective social support. An individual’s threshold is determined by the interaction of diatheses and stress.

Windows of vulnerability for developing specific psychopathologies are believed to exist at different points of the lifespan. Moreover, different diatheses and stressors are implicated in different disorders. For example, breakups and other severe or traumatic life stressors are implicated in the development of depression. Stressful events can also trigger the manic phase of bipolar disorder and stressful events can then prevent recovery and trigger relapse. Having a genetic disposition for becoming addicted and later engaging in binge drinking in college are implicated in the development of alcoholism. A family history of schizophrenia combined with the stressor of being raised in a dysfunctional family raises the risk of developing schizophrenia.

Diathesis-stress models are often conceptualised as multi-causal developmental models, which propose that multiple risk factors over the course of development interact with stressors and protective factors contributing to normal development or psychopathology. For example, a child with a family history of depression likely has a genetic vulnerability to depressive disorder. This child has also been exposed to environmental factors associated with parental depression that increase their vulnerability to developing depression as well. Protective factors, such as strong peer network, involvement in extracurricular activities, and a positive relationship with the non-depressed parent, interact with the child’s vulnerabilities in determining the progression to psychopathology versus normative development.

Some theories have branched from the diathesis-stress model, such as the differential susceptibility hypothesis, which extends the model to include a vulnerability to positive environments as well as negative environments or stress. A person could have a biological vulnerability that when combined with a stressor could lead to psychopathology (diathesis-stress model); but that same person with a biological vulnerability, if exposed to a particularly positive environment, could have better outcomes than a person without the vulnerability.

What is the Impact of Early Manifesting Disorders in the Frame of General Mental Morbidity & of the Effect of Intervention?

Research Paper Title

What happens to children and adolescents with mental disorders? Findings from long-term outcome research.

Background

Research on the long-term outcome of mental disorders originating in childhood and adolescence is an important part of developmental psychopathology.

Methods

After a brief sketch of relevant terms of outcome research, the first part of this review reports findings based on heterotypic cohort studies.

The major second part of this review presents findings based on long-term outcome studies dealing with homotypic diagnostic groups. In particular, the review focuses on the course and prognosis of ADHD, anxiety disorders, depression, conduct disorders, eating disorders, autism spectrum disorders, schizophrenia, and selective mutism.

Results

Findings mainly support the vulnerability hypothesis regarding mental disorders with early manifestation in childhood and adolescence as frequent precursors of mental disorders in adulthood.

Conclusions

The discussion focuses on the impact of early manifesting disorders in the frame of general mental morbidity and of the effect of interventions, which is not yet sufficiently discernible.

  • 1900 – Joseph Zubin, Lithuanian-American psychologist and academic (d. 1990).

Joseph Zubin

Joseph Zubin (09 October 1900 to 18 December 1990) was a Lithuanian born American educational psychologist and an authority on schizophrenia who is commemorated by the Joseph Zubin Awards.

Zubin was born 09 October 1900 in Raseiniai, Lithuania, but moved to the US in 1908 and grew up in Baltimore. His first degree was in chemistry at Johns Hopkins University in 1921, and he earned a PhD in educational psychology at Columbia University in 1932.

In 1946, he was elected as a Fellow of the American Statistical Association.

Zubin was President of both the American Psychopathological Association (195-1952) and the American College of Neuropsychopharmacology (1971-1972) and received numerous awards for his work.

Should We Target Inflammation, The Gut Microbiome, and Mitochondrial Dysfunction in Combat PTSD-Metabolism?

Research Paper Title

Novel Pharmacological Targets for Combat PTSD-Metabolism, Inflammation, The Gut Microbiome, and Mitochondrial Dysfunction

Background

Current pharmacological treatments of post-traumatic stress disorder (PTSD) have limited efficacy.

Although the diagnosis is based on psychopathological criteria, it is frequently accompanied by somatic comorbidities and perhaps “accelerated biological ageing,” suggesting widespread physical concomitants.

Such physiological comorbidities may affect core PTSD symptoms but are rarely the focus of therapeutic trials.

Methods

To elucidate the potential involvement of metabolism, inflammation, and mitochondrial function in PTSD, the researchers integrate findings and mechanistic models from the DOD-sponsored “Systems Biology of PTSD Study” with previous data on these topics.

Results

Data implicate inter-linked dysregulations in metabolism, inflammation, mitochondrial function, and perhaps the gut microbiome in PTSD.

Several inadequately tested targets of pharmacological intervention are proposed, including insulin sensitisers, lipid regulators, anti-inflammatories, and mitochondrial biogenesis modulators.

Conclusions

Systemic pathologies that are intricately involved in brain functioning and behaviour may not only contribute to somatic comorbidities in PTSD, but may represent novel targets for treating core psychiatric symptoms.

An Examination of Environmental Influences on Genomic Variations, Neurodevelopmental Trajectories & Vulnerability to Psychopathology, with a Focus on Externalising Disorders

Research Paper Title

Consortium on Vulnerability to Externalizing Disorders and Addictions (cVEDA): A developmental cohort study protocol.

Background

Low and middle-income countries like India with a large youth population experience a different environment from that of high-income countries.

The Consortium on Vulnerability to Externalising Disorders and Addictions (cVEDA), based in India, aims to examine environmental influences on genomic variations, neurodevelopmental trajectories and vulnerability to psychopathology, with a focus on externalising disorders.

Methods

cVEDA is a longitudinal cohort study, with planned missingness design for yearly follow-up.

Participants have been recruited from multi-site tertiary care mental health settings, local communities, schools and colleges.

10,000 individuals between 6 and 23 years of age, of all genders, representing five geographically, ethnically, and socio-culturally distinct regions in India, and exposures to variations in early life adversity (psychosocial, nutritional, toxic exposures, slum-habitats, socio-political conflicts, urban/rural living, mental illness in the family) have been assessed using age-appropriate instruments to capture socio-demographic information, temperament, environmental exposures, parenting, psychiatric morbidity, and neuropsychological functioning.

Blood/saliva and urine samples have been collected for genetic, epigenetic and toxicological (heavy metals, volatile organic compounds) studies.

Structural (T1, T2, DTI) and functional (resting state fMRI) MRI brain scans have been performed on approximately 15% of the individuals.

All data and biological samples are maintained in a databank and biobank, respectively.

Discussion

The cVEDA has established the largest neurodevelopmental database in India, comparable to global datasets, with detailed environmental characterisation.

This should permit identification of environmental and genetic vulnerabilities to psychopathology within a developmental framework.

Neuroimaging and neuropsychological data from this study are already yielding insights on brain growth and maturation patterns.
