Study Notes on Psychological Diagnosis and Disorders

Introduction to Psychological Diagnosis

  • The foundational text for diagnosing psychological disorders is the DSM.

    • DSM stands for Diagnostic and Statistical Manual.

    • The current edition in use is the fifth edition, known as DSM-5.

Understanding Diagnosis

  • Diagnosis should not be interpreted as a label but rather as a descriptor of someone's experience.

    • Example: Instead of saying someone is "schizophrenic," say they are "suffering from schizophrenia."

    • Analogies used:

    • Broken Leg: We don’t label a person as a "broken leg" but say they are suffering from it.

    • Cancer: We refer to someone as suffering from cancer, not as "being cancer."

    • Anxiety: Use the term “suffering from anxiety” rather than “anxious."

Anxiety Disorders in DSM-5

  • Overview of various anxiety disorders discussed:

    • Obsessive Compulsive Disorder (OCD): A condition characterized by intrusive thoughts (obsessions) and repetitive behaviors (compulsions).

    • Panic Disorder: Involves panic attacks that arise primarily due to underlying anxiety.

    • Specific Phobias: Involve intense fears of specific objects or situations causing severe anxiety.

    • Post-Traumatic Stress Disorder (PTSD): Results from exposure to a traumatic event; characterized by symptoms such as flashbacks and emotional numbness.

    • Definition: Post refers to after; traumatic is the triggering event leading to stress.

    • Social Anxiety Disorder: Excessive fear in social situations, leading to avoidance behavior.

    • Generalized Anxiety Disorder (GAD): A generalized form of anxiety characterized by pervasive worry about various aspects of life.

Coping Mechanisms and Tools for Anxiety

  • Suggestions for managing anxiety include:

    • Organization: Creating lists or schedules to manage overwhelming tasks effectively.

    • Setting Time Limits: Allocate specific time blocks to concentrate on tasks without distractions.

    • Healthy Distractions: Engaging in enjoyable activities such as music, drives, or exercise can reduce anxiety levels.

    • Breathing Techniques: Deep breathing or mindfulness can also help.

    • Reward System: Incentivizing task completion with healthy rewards can motivate individuals.

Obsessive-Compulsive Disorder (OCD)

  • Obsessions: Intrusive and persistent thoughts that can cause significant anxiety.

  • Compulsions: Repetitive behaviors or mental acts performed to alleviate the distress caused by obsessions.

    • Compulsions often include excessive washing, checking, or organizing.

Diagnostic Criteria for PTSD

  • Symptoms of PTSD include:

    • Flashbacks or reliving traumatic events.

    • Avoidance of reminders associated with the trauma.

    • Negative changes in thoughts and mood.

    • Heightened physical arousal or reactivity (e.g., sleep disturbances, hyper-vigilance).

Major Depressive Disorder

  • Characterized by a continuous state of low mood and disinterest in activities once enjoyed.

  • Diagnostic criteria include:

    • Symptoms lasting at least two weeks.

    • Impairment in daily functioning.

    • Symptoms: fatigue, sense of worthlessness, changes in eating or sleeping patterns.

  • Prevalence: Approximately 6% of U.S. adults experience major depression yearly.

Biological and Psychological Factors in Depression

  • Biological: Genetic predispositions and effects of neurotransmitters (e.g., norepinephrine) are involved in depression.

  • Psychological: Stressful life events, negative thought patterns, and learned helplessness contribute to depression.

    • Learned Helplessness: A phenomenon where individuals learn to perceive themselves as lacking control over their circumstances, leading to inaction.

Bipolar Disorder

  • Defined by extreme mood fluctuations from manic highs to depressive lows.

    • Mania: An episode of elevated mood, high energy, and risk-taking behavior.

    • Depressive Episode: A time of deep sadness and lack of interest in life, comparable to major depressive disorder.

  • No middle ground; individuals predominantly swing between extremes.

Suicide and Mental Health

  • Discuss the risks associated with suicidal ideation, particularly in cases of severe depression or after exposure to other suicides.

    • Suicide is a leading cause of death and is often tied to how individuals process their mental illness and its media representation.

  • CDC Definition of Suicide:

    • A death caused by self-directed behavior intending to die as a result of the behavior.

Conclusion and Important Considerations

  • Mental health issues, including anxiety, depression, and bipolar disorder, present complex challenges.

  • Diagnosis is not merely labeling, but understanding the breadth of someone's experience to provide appropriate support and treatment.

  • The DSM-5 serves as an essential guide in identifying and treating psychological disorders effectively, with ethical considerations surrounding the language used in diagnosis.
