Notes on Psychological Disorders

Concepts of Abnormality and Psychological Disorders

Psychological disorders, also known as mental disorders, refer to a variety of conditions that affect a person's thinking, feeling, and behavior. To understand these disorders, several common definitions of abnormality have been proposed. The most recognized approach defines abnormal behavior through four key dimensions known as the 'four Ds': 1. Deviance: Behavior that is significantly different from societal norms. 2. Distress: The behavior causes personal suffering or distress. 3. Dysfunction: The behavior interferes with a person’s ability to function in daily life. 4. Danger: The behavior poses a risk of harm to the individual or others.

Historical Perspectives on Psychological Disorders

The understanding of psychological disorders has evolved throughout history:

• Supernatural Views: Early beliefs attributed abnormal behavior to supernatural forces or evil spirits, leading to practices like exorcism.
• Biological Views: Ancient physicians, like Hippocrates, suggested that psychological disorders were related to bodily functions. The biological view focuses on genetics, neurochemistry, and physiological factors affecting behavior.
• Psychological Views: Emphasizing personal experiences and conflicts, psychological perspectives explore how thought patterns, emotional responses, and social interactions contribute to abnormal behavior.

Classification of Psychological Disorders

Two primary classification systems are used globally:

1. ICD-10 (International Classification of Diseases) developed by the World Health Organization (WHO).
2. DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) published by the American Psychiatric Association (APA). These classification systems help clinicians diagnose and communicate about psychological disorders effectively.

Factors Underlying Abnormal Behavior

Psychological disorders arise from a combination of biological, psychological, and socio-cultural factors:

• Biological Factors: Genetic predispositions, hormonal imbalances, and neurochemical disruptions can influence behavior. Evidence links certain neurotransmitter abnormalities to disorders like depression and schizophrenia.
• Psychological Factors: Cognitive distortions, insufficient coping mechanisms, and past traumatic experiences can increase vulnerability to psychological disorders. Various psychological models include the psychodynamic, behavioral, cognitive, and humanistic-existential approaches.
• Socio-Cultural Factors: Factors like familial dynamics, societal expectations, and cultural norms greatly affect an individual’s mental health.

Major Psychological Disorders

Understanding major psychological disorders provides insight into their complexities:

1. Anxiety Disorders: Characterized by excessive fear or anxiety, these include Generalized Anxiety Disorder, Panic Disorder, Phobias, and Separation Anxiety Disorder.
2. Obsessive-Compulsive and Related Disorders: Involves obsessions (persistent thoughts) and compulsions (repetitive behaviors) like compulsive hoarding or washing hands.
3. Trauma-and Stressor-Related Disorders: Includes PTSD, where individuals experience distressing memories following traumatic events.
4. Somatic Symptom and Related Disorders: Psychological stress manifests as physical symptoms, lacking an identifiable medical cause.
5. Dissociative Disorders: Characterized by a disconnection from thoughts, identity, consciousness, or memory, including Dissociative Amnesia and Dissociative Identity Disorder.
6. Depressive Disorders: Symptoms include persistent sadness, lack of interest, and emotional disturbances affecting daily life.
7. Bipolar and Related Disorders: Involves mood fluctuations, from manic highs to depressive lows.
8. Schizophrenia Spectrum and Other Psychotic Disorders: A serious mental illness characterized by disturbances in thought processes and emotional responses, including hallucinations and delusions.
9. Neurodevelopmental Disorders: Conditions like Autism Spectrum Disorder manifest early, affecting social interaction and behavior.
10. Disruptive, Impulse-Control, and Conduct Disorders: Involves defiant and aggressive behaviors in children.
11. Feeding and Eating Disorders: Includes anorexia and bulimia, which are often linked to body image issues.
12. Substance-Related and Addictive Disorders: Characterized by dependence on substances like alcohol or narcotics that lead to significant impairment.

Various disorders, defined in clinical terms, highlight the need for comprehensive variables influencing mental health. Treatment approaches may vary but often include therapy, medication, or a combination of both, underscoring the complexities of mental health treatment today.
