Study Notes
Anxiety and OCD Lecture Notes
- Anxiety is a common human experience, featuring feelings of apprehension, unease, and dread, triggered by a real or perceived threat. It's distinct from fear, which reacts to a specific danger.
Levels of Anxiety
- Mild Anxiety: A normal, necessary response for survival, enhancing focus and problem-solving abilities.
- Moderate Anxiety: Focus narrows, attention becomes selective, but clarity of thought reduces.
- Severe Anxiety: Perception significantly decreases, leading to difficulty concentrating and overwhelming feelings.
- Panic: The most intense level, characterized by a loss of ability to process the environment, causing dissociation, confusion, or terror.
Generalized Anxiety Disorder (GAD)
- Symptoms: Chronic, excessive worry across life domains for at least six months, accompanied by physical symptoms like restlessness, muscle tension, fatigue, and irritability.
- Interventions: Psychotherapy (CBT), pharmacotherapy using SSRIs, SNRIs, or occasionally benzodiazepines (short-term), and lifestyle modifications like exercise, sleep hygiene, and relaxation techniques.
Panic Disorder
- Symptoms: Recurrent, unexpected panic attacks marked by intense fear, discomfort, physical symptoms (chest pain, dizziness, palpitations, shortness of breath), and a feeling of impending doom.
- Interventions: Cognitive Behavioral Therapy (CBT), particularly with exposure therapy, pharmacotherapy using SSRIs, benzodiazepines, and patient education about the physical effects of anxiety to diminish fear during attacks.
Phobias
- Specific Phobia: Fear of specific objects or situations (e.g., heights, flying).
- Social Anxiety Disorder (Social Phobia): Fear of social situations involving potential scrutiny by others, leading to avoidance of social events.
- Agoraphobia: Fear of open spaces or situations where escape might be difficult (e.g., public transportation, crowded places).
- Interventions: Systematic desensitization (gradual exposure to the feared object/situation), CBT to modify irrational fears, and medications (SSRIs or beta-blockers, especially for performance-related anxiety).
Obsessive-Compulsive Disorder (OCD)
- Obsessions: Persistent, intrusive thoughts, urges, or images causing anxiety (e.g., fear of contamination, intrusive sexual or aggressive thoughts).
- Compulsions: Repetitive behaviors or mental acts (e.g., excessive handwashing, checking) performed in response to obsessions.
- Diagnostic Criteria (DSM-5): Obsessions, compulsions, or both, significantly impacting daily life, lasting over one hour per day, and not attributable to substance use or another medical condition.
- Common Subtypes: Contamination and cleaning, harm obsessions and checking, symmetry, order, and counting, taboo or forbidden thoughts.
- Interventions: CBT with Exposure and Response Prevention (ERP), SSRIs are first-line medications.
Body Dysmorphic Disorder (BDD)
- Symptoms: Preoccupation with an imagined or exaggerated flaw in appearance, leading to compulsive behaviors like excessive grooming, mirror checking, or seeking cosmetic surgery.
- Interventions: CBT focusing on cognitive distortions and body image issues, SSRIs to reduce obsessive thinking.
Hoarding Disorder
- Symptoms: Difficulty discarding possessions regardless of value, leading to clutter obstructing living spaces and daily functioning.
- Interventions: CBT emphasizing organizational skills and reducing acquisition, motivational interviewing for engagement in treatment.
Trichotillomania (Hair-Pulling Disorder) and Excoriation (Skin-Picking Disorder)
- Symptoms: Repeated pulling of hair or picking of skin leading to noticeable hair loss or skin lesions.
- Interventions: CBT focusing on habit-reversal techniques, medications such as SSRIs may help reduce compulsive urges.
Neurobiology of Anxiety and OCD
- Amygdala: Central to fear and anxiety processing, hyperactivity linked to anxiety disorders.
- Prefrontal Cortex: Plays a role in regulating the amygdala's response to anxiety, impaired in some OCD cases.
- Neurotransmitters: Serotonin dysregulation commonly associated with OCD and anxiety disorders. Norepinephrine plays a role in the "fight or flight" response; GABA is a primary inhibitory neurotransmitter.
Course and Prognosis
- OCD is typically chronic, with waxing and waning symptoms.
- Early treatment with CBT and/or medications improves long-term outcomes; full remission is less common.
Differential Diagnosis
- OCPD: General preoccupation with orderliness, perfectionism, and control, lacking specific intrusive obsessions and compulsions.
- Other Anxiety Disorders: Conditions like GAD or specific phobias might involve excessive worry but lack the repetitive behaviors of OCD.
- Tic Disorders: Individuals can have OCD along with tics or a diagnosis of Tourette's syndrome.
