  • Fear

    • Immediate alarm reaction to present danger activating a massive response from the autonomic nervous system (flight or fight)

  • Panic attack

    • Abrupt experience of intense fear or discomfort in the absence of danger accompanied by physical symptoms (dizziness, heart palpitations, chest, pain, shortness of breath)

Anxiety and its causes

  • Causes of Anxiety

    • Biological contributions

      • Inherited tendency to be tense, behavioral inhibition system (anxiety), flight or fright system (panic)

    • Psychological contributions

      • Early childhood (overprotective and overintrusive parents, psychological vulnerability

    • Social contributions

      • Social pressures (family, job, school)

    • Comorbidity of anxiety disorders

      • Co-occurrence of two or more disorders in a single individual (high (50%) in anxiety disorders)

Generalized anxiety disorder l.jpg

Generalized anxiety disorder

  • Intense, uncontrollable, unfocused, chronic, and continuous worry and mental agitation that is distressing and unproductive accompanied by physical symptoms of tenseness, irritability and restlessness (generalized to everyday life)

  • 4% of population (two thirds are women), onset in early adulthood

  • Psychological treatments (CBT, meditation) have approx. the same benefit as drugs (benzodiazepines) but are better in the long term

  • Cognitive-Behavioral Therapy (CBT)

    • systematic exposure to anxiety-provoking situations or thoughts

    • learning to substitute positive behaviors and thoughts for negative ones

    • learning new coping skills; relaxation, meditation, breathing exercises
