Chapter 7 Anxiety Disorders Extraordinary People Mark Summers, TV Show host who suffered from Obsessive Compulsive Disorder Anxiety: a state of apprehension, tension, and worry. There are several symptoms that qualify as symptoms of anxiety, and can fall under somatic, emotional, cognitive, and behavioural. Neurosis: according to Freud, a set of maladaptive symptoms caused by unconscious anxiety Panic attacks: short but intense periods in which many symptoms of anxiety are experienced which can include heart palpitations, trembling, a feeling of choking, dizziness, intense dread, and so on. When four or more symptoms occur frequently and interfere with daily living the individual may be diagnosed with panic disorder. Panic disorder: when panic attacks become a common occurrence, when the panic attacks are usually not provoked by any particular situation and when a person begins to worry about having attacks and changes behaviours as a result of this worry, they could be diagnosed with panic disorder. Appears to run in families, may be a biological vulnerability to this disorder Norepinephrine: found that antidepressant medications reduce panic attacks, which led to the belief that Norepinephrine may be involved in panic disorder, it may be poorly regulated in people with panic disorder, especially in an area of the brain stem called the locus ceruleus. Limbic system: a part of the brain that relays information from the primitive brain stem about changes in bodily functions to the cortex, where the information is interpreted. Limbic system may be involved in diffuse, anticipatory anxiety. Poor regulation in the locus ceruleus causes panic attacks, which then stimulate and kindle the limbic system, lowering the threshold for the activation of diffuse and chronic anxiety. The Kindling Model of Panic Disorder ^ Those with panic disorder can be made to have a panic attack when asked to hyperventilate or inhale small amounts of carbon dioxide Cognitive Model www.notesolution.com
