Summary of "Що відбувається, коли все йде не так: психічні розлади (частина I)"

Purpose of the talk

Provide an overview of how modern clinical psychology defines and studies mental disorders, using mood disorders (major depression and bipolar disorder) as primary examples.
Describe diagnostic approaches, key symptoms/criteria, prevalence, major etiological theories (biological, cognitive‑behavioral, interpersonal), brain/neurotransmitter findings, and main treatments (medication and psychotherapy).

How “abnormality” is defined (diagnostic issues)

There is no biological test for mental disorders; diagnosis is based on behavioral criteria (symptoms reported and observed behavior) and clinician judgment. Those judgments are necessarily subjective and influenced by social, cultural, and individual factors:

Social and cultural norms (e.g., different meanings attached to wearing a hijab).
Personal characteristics and social roles (gender norms affect interpretation of crying or aggression).
Circumstances and environment (paranoia may be adaptive in dangerous contexts).

Clinical heuristics — the “three Ds”:

Distress: causes significant suffering (e.g., depression). Dysfunction: interferes with everyday functioning (work, school, relationships). Deviance: highly unusual behavior/experiences relative to cultural norms.

Diagnostic system: DSM

The Diagnostic and Statistical Manual (DSM) provides symptom lists, required numbers of symptoms, and embeds the concepts of distress, dysfunction, and deviance.
Modern DSM criteria emphasize observable, reliable signs so clinicians can reach more consistent diagnoses than older, theory-driven systems.

Mood disorders — classification and prevalence

Two broad classes:

Unipolar depressive disorders (depression only).
Bipolar disorders (alternation between depressive and manic episodes).

Prevalence and patterns:

Major depression: common — roughly 1 in 4 women and about 13% of men will experience serious depression at least once. Peak onset is in the late teens/early 20s (college years).
Bipolar disorder: about 1% lifetime prevalence, roughly equal in men and women.
Age trends: highest rates in ages 15–24; reported rates are lower in older adults (possible reasons include cohort effects, survivorship bias, and social/historical changes).
Gender trends: gender difference in depression emerges at puberty — by late adolescence females show approximately twice the rates of males. Multiple interacting explanations exist (biological, social, and differential exposure to stress).

DSM criteria — Major Depressive Episode

Required:

Either depressed mood (sadness, longing) OR markedly diminished interest/pleasure (anhedonia).

Plus at least four of the following:

Significant change in weight or appetite.
Sleep disturbance: insomnia, hypersomnia, or early morning awakening.
Psychomotor retardation or agitation (retardation is more common).
Fatigue or loss of energy.
Feelings of worthlessness or excessive/inappropriate guilt (may become psychotic in severe cases).
Decreased ability to concentrate or indecisiveness.
Recurrent thoughts of death, suicidal ideation, or suicidal behavior.

Time threshold:

Symptoms must persist for at least two weeks (typical untreated episodes often last much longer — roughly six months on average).

Major Depressive Disorder — clinical observations

Depression ranges from normal sadness to severe, incapacitating illness. Many people (“walking wounded”) force themselves to function while severely depressed and may not seek treatment.
Suicidal ideation is common across psychopathology but particularly frequent in depression.

Bipolar disorder — mania criteria and clinical issues

Manic episode:

Abnormally elevated/expansive or irritable mood lasting at least one week.

Plus three or more of:

Inflated self-esteem or grandiosity.
Decreased need for sleep.
Pressured/talkative speech and racing thoughts.
Distractibility.
Increased goal-directed activity or psychomotor agitation.
Engagement in risky, pleasurable activities (sexual indiscretions, spending sprees, substance use).

Clinical points:

Mania exists on a spectrum from hypomania (milder) to severe mania with psychosis (grandiose delusions are common).
Consequences include legal, financial, and social harm; risky behaviors; and interpersonal damage.
Mania can be subjectively pleasurable, which complicates help-seeking and adherence to treatment.
Bipolar disorder is less common than unipolar depression and is often more challenging to treat because of mood swings.

Etiology — overview: genetics, neurotransmitters, brain areas, gene × environment

Genetics:

Bipolar disorder shows a strong genetic influence (high concordance in monozygotic vs dizygotic twins).
Depression has heritability, particularly for early-onset cases; life-event–triggered depression shows a less clear genetic pattern.

Neurotransmitters:

Monoamines (serotonin, norepinephrine, dopamine) are implicated. Current models emphasize receptor function and signaling pathways rather than a simple “deficit” model.

Gene × environment interaction:

Research (e.g., Caspi et al.) suggests that variants of the serotonin transporter gene (short alleles) increase risk for depression primarily among people exposed to severe stress or abuse — genes moderate vulnerability to stress rather than directly causing depression.

Brain regions:

Prefrontal cortex: reduced activity in depression → impaired planning, concentration, and goal-directed behavior.
Amygdala: hyperreactivity to emotional stimuli in mood disorders.
Hippocampus: chronic depression is associated with reduced hippocampal volume → memory and attention problems.
Anterior cingulate cortex: dysregulation is linked to stress response and decision-making.

Treatments — biological and psychosocial

Medications:

Older classes: monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants — effective but with significant side effects and overdose risk.
SSRIs and SNRIs (e.g., Prozac, Paxil): became dominant due to better tolerability; effectiveness is similar to older drugs for many patients, but not everyone responds and trials are often needed.
Lithium: a first-line mood stabilizer for bipolar disorder — reduces mood swings but has side effects, teratogenic risks, and requires monitoring.
Antipsychotics: used when psychosis is present or as augmentation in bipolar treatment.

Psychotherapies:

Cognitive Behavioral Therapy (CBT, Aaron Beck)
- Theory: depression is maintained by a negative cognitive triad (negative views of self, world, future) and cognitive distortions (all-or-nothing thinking, emotional reasoning, personalization).
- Core methods:
  - Identify negative automatic thoughts and core beliefs.
  - Challenge the accuracy of those thoughts (seek evidence and alternative interpretations).
  - Teach cognitive restructuring and problem-solving.
  - Behavioral activation and skills training to change environmental contributors.
  - Homework and skill practice (anticipatory coping and self-statements between sessions).
- Evidence: CBT is as effective as SSRIs in many studies and reduces relapse risk more than medication discontinuation in some trials.
Interpersonal Therapy (IPT)
- Focuses on how current interpersonal relationships and past relational patterns contribute to depression.
- Works on understanding and changing relationship patterns; less structured than CBT but effective, especially when depression is linked to interpersonal problems.

Clinical takeaway:

Multiple evidence-based options exist (medication, CBT, IPT). Choice should be individualized, and combined treatments are often used depending on severity and type of mood disorder.

Illustrative video vignettes and clinical observations

Lecture materials included clips demonstrating real-life presentations and variability:

A woman with recurrent severe depression.
An elderly woman in a manic episode.
A man (“Bernie”) describing bipolar experiences. These vignettes highlighted symptom presentation, variability in response to treatment (e.g., lithium), and practical challenges.

Concrete diagnostic and clinical checklists (quick references)

Major depressive episode:
- Depressed mood OR anhedonia, plus ≥4 of the specified symptoms (appetite/weight change, sleep disturbance, psychomotor change, fatigue, worthlessness/guilt, concentration problems, suicidal ideation) for ≥2 weeks.
Manic episode:
- Elevated or irritable mood for ≥1 week plus ≥3 of the specified manic symptoms (grandiosity, decreased need for sleep, pressured speech, racing thoughts, distractibility, increased activity, risky behaviors).

Main lessons and implications

Mental disorders are defined behaviorally and contextually; cultural, gender, and situational factors affect what is labeled “abnormal.”
Mood disorders are common, disabling, and often begin in adolescence or early adulthood.
Etiology is multifactorial: genes, neurobiology, stressful life events, and cognitive/interpersonal processes interact.
Effective treatments exist: various medication classes and psychotherapies (especially CBT and IPT); CBT has strong evidence for both acute treatment and relapse prevention.
Early identification and treatment matter because untreated episodes are often long and impairing.
