    Study Notes

    Neuroendocrinology and Anxiety

    • Noradrenaline increases in anxiety, triggering autonomic nervous system symptoms.
    • Gut hormones like cholecystokinin and substance P have a modulatory effect on anxiety.

    Psychological Explanations of Anxiety

    • Cognitive theories categorize anxiety explanations into classical conditioning, operant conditioning, and cognitive biases.

    Cognitive Theory - Classical Conditioning

    • Fear conditioning occurs when a neutral unconditioned stimulus is repeatedly paired with an aversive conditioned stimulus, eliciting a conditioned response even without the unconditioned stimulus.

    Cognitive Theory - Operant Conditioning

    • Escape and avoidance behaviors are negatively reinforced when individuals remove themselves from aversive situations, maintaining anxiety levels.

    Cognitive Theory - Cognitive Biases

    • Attention bias leads to a focus on threats, interpretation bias results in negative interpretations of ambiguous stimuli, and confirmation bias causes selective attention to beliefs. These biases correlate with frontal hypo-responsivity and amygdala hyper-responsivity.

    Importance of Anxiety Disorders

    • Pre-pandemic data indicated a 6.6% prevalence of anxiety disorders in the UK.
    • In Foundation Year 1 doctors, prevalence rose from 22.8% in 2010 to 29.6% in 2017.
    • Medical students exhibit higher anxiety rates (47.1%) compared to non-medical peers (39%).
    • Among neurodiverse individuals, anxiety prevalence ranges from 42-79%.

    DSM-5 Anxiety Disorders

    • Major anxiety disorders include Generalized Anxiety Disorder (GAD), Panic Disorder with Agoraphobia, Social Anxiety Disorder, Obsessive-Compulsive Disorder (OCD), and PTSD/Acute Stress Disorder.

    Generalized Anxiety Disorder

    • UK prevalence: 7.2%.
    • Characterized by persistent worry disproportionate to risk and at least three of the following: restlessness, fatigue, poor concentration, irritability, muscle tension, sleep disturbance for a duration of at least six months.

    Panic Disorder

    • Involves repeated panic attacks accompanied by intense fear and avoidance behaviors.
    • Symptoms include airway and respiratory sensations, circulatory symptoms (palpitations), cognitive symptoms (depersonalization), and abdominal discomfort for at least one month.

    Social Anxiety Disorder

    • Defined by a persistent fear of social or performance situations leading to possible scrutiny, accompanied by maladaptive behaviors and an awareness of excessive fear.

    Psychosocial Theory of Anxiety

    • Adverse life events can trigger fear or trauma responses and earlier unresolved crises contribute to acquired anxiety, leading to cognitive and neurological adaptations.

    Social Learning Theory

    • Vicarious learning, or observational learning, plays a role in acquiring common phobias such as fear of spiders (arachnophobia) and heights (acrophobia).

    Biopsychological Treatments for Anxiety Disorders

    • Treatments are grouped into biological and psychological categories.

    Biological Treatments

    • Antidepressants, particularly SSRIs (e.g., sertraline, fluoxetine), increase serotonin availability, with potential side effects including gastrointestinal issues and heightened suicidal ideation in young individuals.
    • Anxiolytics and square breathing techniques can also be employed.

    Cognitive Behavioral Therapy (CBT)

    • Focuses on present thoughts and behaviors, aiming to challenge cognitive biases that maintain anxiety.

    Psychotherapy and Counselling

    • Psychodynamic psychotherapy explores past experiences affecting current psychological states, while counselling promotes personal growth and healthier decision-making.

    Eye-Movement Desensitization and Reprocessing (EMDR)

    • Specifically designed for PTSD, this structured approach helps patients process distressing memories while focusing on external stimuli.

    NICE Guidelines for Treating Anxiety Disorders

    • Treatment steps include self-help strategies, psychological therapies (primarily CBT), and medications (SSRIs as first-line when other steps fail).
