Panic Disorder • People with panic disorder experience sudden episodes of sheer terror. • Characterized by intense physical symptoms (Write down 3) • Profuse sweating • Nausea • Numbness or tingling • Chills • Trembling • Chest pain • Shortness of breath • Rapid heartbeat
Panic Disorder • Panic disorder can, at first, come out of the blue. • Later, they are usually associated with situations • Agoraphobia can develop in people who have panic disorders.
Generalized Anxiety Disorder • Experience persistent anxiety that is not tied to any particular object or situation. • Anxiety is a “free floating” quality that travels with the person from place to place.
Obsessive-Compulsive Disorder • Persistent obsessions and/or compulsions. • Nagging, intrusive thoughts that are unable to be controlled. • Compulsions are repetitive behaviors or “rituals” the person performs again and again.
So… • What’s the difference between a compulsion and a superstition?
Causes of Anxiety Disorders • Biological Factors • Genetics have been found to be a cause of panic disorders, generalized anxiety disorder, OCD, and phobic disorders
Causes of Anxiety Disorders • Biological Factors • Biochemical changes in brain trigger an “internal alarm” to induce panic • Obsessional thinking may be linked to danger sensing areas of the brain may be heightened in some people.
Causes of Anxiety Disorders • Psychological Factors • Phobias may be learned through classical conditioning (people who have been bit by dogs maybe scared of them). • Operant conditioning may reinforce avoidance behavior (avoidance of object is negatively reinforced by feelings of safety).
Causes of Anxiety Disorders • Negative reinforcement can help perpetuate OCD (obsessive thoughts trigger anxiety, which is partially relieved through performing a ritual. In effect, the solution becomes the problem)
Causes of Anxiety Disorders Triggering stimulus (internal or external) Perceived Threat Catastrophic interpretations of sensations Feelings of apprehension or worry Body Sensations
