Study Notes
Anxiety Disorders: Aetiology and Treatment
- Fear: A response to immediate threat, useful for quick adaptive reactions.
- Anxiety: Apprehension about a future threat, a future-focused cognitive response connecting basic emotions. It's less "hardwired" than fear and varies by individual and situation.
- Both are adaptive responses to threat, useful for preparedness. Anxiety increases preparedness (Yerkes & Dodson, 1908). Fear triggers the "fight or flight" response aiding survival.
- Maladaptive anxiety: Excessive intensity, frequency or duration can lead to emotional and anxiety disorders (Barlow, 2002).
- Cycle of Anxiety: Cognitive thoughts about the anxiety-provoking situation create an emotional fear response. This leads to a physiological response triggering avoidance behavior. This cycle repeats, reinforcing the anxiety and avoidance.
Fear Conditioning
- Mowrer's Two-Factor Model: A model consisting of classical and operant conditioning.
- Classical Conditioning: An individual learns a fear response to a neutral stimulus (CS) repeatedly paired with an intrinsically aversive stimulus (UCS).
Generalised Anxiety Disorder (GAD)
-
DSM-5 criteria: Excessive anxiety and worry (apprehensive expectation) about two or more life domains. Occurs more days than not for 3+ months. Often associated with restlessness, muscle tension, avoidance of activities or events with possible negative outcomes. This includes time/effort preparing for such events, procrastination due to worries and seeking reassurance by others. Impairment in social, occupational, or other important areas of functioning. A key point is the disturbance is not caused or exacerbated by the direct physiological effects of a substance, or another medical condition, nor should it be attributed to another mental disorder.
-
Aetiology and Prevalence: More common in women, ages 35-59. Data from National Comorbidity Survey Replication (NCS-R) shows varying prevalence rates across different age groups (18-29, 30-44, 45-59, 60+). GAD etiology involves Biological (genes, brain areas, neurotransmitters) or Psychological theories (informational processing biases, beliefs, meta-beliefs, worrying function).
-
Biological factors: Genetics play a role (Noyes et al., 1992). Twin studies (MZ vs DZ) show heritability around 30% (Dellava, Kendler & Neale, 2011). Amygdala (emotional regulation) and Prefrontal cortex (decision-making) may also be involved. Imbalance relating to Serotonin, Norepinephrine & GABA.
-
Psychological Factors: Unpredictable and stressful events can increase GAD risk.
Worry
- Cognitive Avoidance Response (Borkovec & Newman): Worry distracts from distressing material, acts as a form of negative reinforcement.
- Intolerance of Uncertainty (Dugas, Marchand & Ladouceur 2005): A dispositional characteristic that makes people want to reduce ambiguity and uncertainty.
- Contrast Avoidance Model: People engage in worry to ensure they are ready a worst case scenario
- Metacognitive Model (Wells, 1995): Adaptive Worry (Type 1) is normal and functional; Meta-worry (Type 2) is pathological, worrying about worrying.
Parenting Styles and Psychological Factors related to GAD
- Parenting styles: Insecure attachment associated with uncaring environment may contribute to difficulties in dealing with difficult situations.
Treatment of GAD
- Pharmacological: Anxiolytics or Anti-depressants (SSRI).
- Psychological: Stimulus control and exposure, Cognitive Behavioral Therapy (CBT) includes self-monitoring, relaxation training, cognitive restructuring, behavioral rehearsal. Cognitive bias modification (CBM).
Panic Disorder and Agoraphobia
- Panic Attacks: An abrupt surge of intense fear or discomfort peaking within minutes. Can be "out-of-the-blue" or associated with specific situations.
- DSM-5 Panic Disorder criteria: Recurrent unexpected panic attacks for one month or more after the attack; persistent concern or worry about additional attacks; significant maladaptive changes in behavior; not due to substance or medical condition or another mental disorder (e.g., Social Anxiety, Specific Phobia, Obsessive-Compulsive Disorder, Posttraumatic Stress Disorder, Separation Anxiety).
- DSM-5 Agoraphobia criteria: Marked fear or anxiety about two or more situations leading to avoidance or needing a companion. Situations include public transportation, open spaces, shops, theaters, lines/crowds, outside of home alone, etc; fear out of proportion to actual danger; situations are actively avoided, require a companion, or endured with marked fear/anxiety; disturbance persists for 6+ months; causes significant impairment.
Psychological theories of Panic Disorder
- Classical Conditioning: Linking bodily sensations to panic attacks and anxiety-provoking situations.
- Interoceptive Conditioning: Conditioning panic in response to internal bodily sensations. (Panic is separate from anxiety. Anxiety is anticipatory preparedness for an attack and panic is when the attack is already happening).
Biological Factors related to Panic Disorder
- Hyperventilation: Rapid breathing exceeding metabolic demand leading to a reduction in CO2 levels, which can induce symptoms (dizziness, lightheadedness).
- Neurotransmitter Imbalance: Deficient GABA neurons, overactivity of Noradrenaline.
Treatment of Panic Disorder
- Pharmacological: Tricyclic Antidepressants, SSRIs (second-line NICE recommendation). Benzodiazepines are not recommended by NICE.
- Psychological: Cognitive Behavioral Therapy (CBT) including Interoceptive Exposure, Cognitive Restructuring, Relaxation, Breathing retraining.
