In-Depth Notes on Mental Health and Disorders Preparation
I. Perspectives
Seven Perspectives of Psychology
- Psychoanalytic: Unconscious mind, childhood experiences
- Behavioral: Conditioning, observable behavior
- Cognitive: Thought processes, mental functions
- Humanistic: Personal growth, self-actualization
- Biological: Genetic influences, neurochemical activity
- Evolutionary: Adaptation, survival behaviors
- Sociocultural: Social context, cultural influences
Biopsychosocial Model
- Causes: Mental disorders arise from a combination of biological, psychological, and social factors.
- Treatment: Integrates multiple approaches, addressing the biological, psychological, and social dimensions of disorders.
Diathesis-Stress Model
- Explains that individuals may inherit a predisposition (diathesis) that, when coupled with stressful life experiences, increases the likelihood of developing a disorder.
Eclectic Approach
- Combines techniques and ideas from different therapeutic schools to tailor treatment based on the individual client's needs.
II. Intro to Disorders
Disordered Definition
- Deviates greatly from societal norms or is characterized by dysfunction, distress, and dangerousness.
Diagnosis Requirements
- Evidence of symptoms, impairment in functioning, duration of symptoms, and the application of diagnostic criteria.
DSM (Diagnostic and Statistical Manual of Mental Disorders) & ICD (International Classification of Diseases)
- Commonality: Both serve to standardize classification and criteria for mental health diagnoses.
Pros & Cons of Diagnosing
- Positives: Leads to proper treatment, helps in understanding the disorder, provides a common language.
- Negatives: May stigmatize individuals, potential for over-diagnosing, and may overlook individual variations.
III. Depressive Disorders
Features
- Consistent feeling of sadness, loss of interest or pleasure, and other cognitive and physical symptoms.
- Includes Major Depressive Disorder (MDD) and Persistent Depressive Disorder (PDD).
Symptoms of Major Depressive Disorder (MDD)
- Persistent sadness, loss of interest, changes in appetite, sleep disturbances, fatigue, feelings of worthlessness, difficulty concentrating, and suicidal thoughts.
Symptoms of Persistent Depressive Disorder (PDD)
- Chronic sadness lasting for at least two years, similar symptoms as MDD but usually less severe.
Biological/Evolutionary Causes
- Genetic predisposition, neurotransmitter imbalances (e.g., serotonin, norepinephrine).
Behavioral & Cognitive Causes
- Negative thought patterns, learned helplessness, lack of reinforcement.
Sociocultural Explanation
- Socioeconomic status, cultural stigma, access to mental health services.
Biopsychosocial Explanation
- Combination of biological (genetic), psychological (thought patterns), and social factors contributing to the development of MDD and PDD.
Diathesis Stress Application
- Yes. Individuals may have a vulnerability to depression triggered by stressful life events.
IV. Bipolar Disorder
Common Features
- Alternating episodes of mania (elevated mood, increased energy) and depression.
- Mania: Excessively euphoric, energetic states; Hypomania: Less severe form.
Types
- Type I: Full manic episodes, may have depressive episodes.
- Type II: At least one hypomanic episode and one major depressive episode.
Biological Causes
- Genetic factors, neurotransmitter fluctuations (e.g., serotonin, dopamine).
V. Schizophrenia
Five Symptoms
- Delusions, hallucinations, disorganized thinking, negative symptoms, and abnormal motor behavior.
Hallucinations vs. Delusions
- Hallucinations: Perceptions without external stimuli (e.g., hearing voices).
- Delusions: Strongly held false beliefs (e.g., believing one is controlled by external forces).
Types of Delusions
- Paranoid Delusions: Believing others are plotting against you.
- Grandiose Delusions: Believing one has exceptional abilities or fame.
Word Salad

- Catatonic Stupor: Lack of response or movement, often in a fixed position.
Positive & Negative Symptoms
- Positive: Hallucinations, delusions, disorganized speech.
- Negative: Apathy, lack of emotional expression, anhedonia.
Acute vs. Chronic Schizophrenia
- Acute: Sudden onset of symptoms and generally better prognosis.
- Chronic: Long-term symptoms with a gradual onset, typically more severe.
Biological Explanation
- Involves genetic factors, brain structure abnormalities (enlarged ventricles), and neurotransmitter dysregulation (dopamine hypothesis).
- Diathesis-Stress: Yes, vulnerable individuals may develop schizophrenia when exposed to stressors.
VI. Anxiety Disorders
Common Features
- Excessive fear or anxiety, significant distress or impairment.
- Disorders include Generalized Anxiety Disorder (GAD), Panic Disorder, Phobias (specific and social), Agoraphobia, and others.
Symptoms of Phobic Disorder

Symptoms of Panic Disorder
- Recurring panic attacks, symptoms include rapid heartbeat, sweating, trembling, and feelings of impending doom.
Culture Bound Disorder

Social Anxiety Disorder Symptoms
- Intense fear of social situations, often leading to avoidance; may coincide with Agoraphobia.
Taijin Kyofusho
- A cultural syndrome in Japan characterized by fear of offending others or how one’s body appears to others.
Symptoms of Generalized Anxiety Disorder
- Chronic worry about various aspects of life, fatigue, irritability, muscle tension, and sleep disturbances.
Behavioral Explanation of Anxiety Disorders
- Anxiety as a learned response, often linked to previous negative experiences or conditioning.
Biological/Evolutionary Explanation
- Genetic predisposition, irregularities in brain function, and evolutionary mechanisms of fear response.
Cognitive Explanation
- Dysfunctional thought patterns, such as catastrophizing, excessive self-monitoring, and unrealistic expectations.
VII. Dissociative Disorders
