Epidemiology of Panic Disorder • Defining features • Panic-related apprehension • Persistent worry about having more attacks • Unrealistic concern about the consequences of panic attacks • Changes in behavior to cope with fear of mpanic (safety behaviors) Behavior Therapy Class

Panic-Related Appraisals(Telch et al, 1989) • Overestimate the likelihood of panic occurrence • Underestimate one’s ability to cope with panic • Exaggerate the negative consequences of panic attacks Behavior Therapy Class
Epidemiology of Panic Disorder • Prevalence • General population…………………. 3.5%* • Primary care………………………… 6 - 10% • Cardiologists………………………… 30-50% • Gender Distribution • 2 to 1 Women for PD uncomplicated • 4 to 1 Women for PD with agoraphobia *Data from the National Comorbidity Study - Kessler et al, (1994) Behavior Therapy Class
Epidemiology of Panic Disorder • Onset and course • Onset occurs early to mid 20s • Course is chronic Behavior Therapy Class

“Men are disturbed not bythings but by the views which they take of them”(Epictetus, 60 A.D.)“Meanings are not determined by situations, but we determine ourselves by the meanings we give to situations”(Adler, 1931) Behavior Therapy Class

Medications with Established Efficacy in Panic Disorder • TCAs (e.g., imipramine) • MAOIs (e.g., phenelzine) • High-potency BZs (e.g., alprazolam) • SSRIs (e.g., paroxetine) Behavior Therapy Class
Cognitive-Behavioral Treatment of Panic Disorder Behavior Therapy Class
Major Treatment Components of CBT for Panic Disorder • Education • Major Aim: • Provide information to enhance the patient’s knowledge concerning anxiety and panic and to reduce misconceptions that anxiety/panic are dangerous. • Strategy: • Didactic instruction and hand-outs Behavior Therapy Class
Major Treatment Components of CBT for Panic Disorder • Breathing retraining • Major Aim: • Teach the patient a coping skill that can be used to: (a) prevent hyperventilation and (b) manage anxiety • Strategy: • Training in diaphragmatic breathing Behavior Therapy Class
Major Treatment Components of CBT for Panic Disorder • Cognitive restructuring • Major Aim: • Teach patients to identify and correct faulty threat perceptions that are maintaining their panic/anxiety. • Strategy: Cognitive therapy techniques Behavior Therapy Class
Targets for Cognitive Intervention in Panic Disorder • Faulty beliefs about physical sensations • Overestimations in the likelihood of panic occurrence • Faulty beliefs about the the consequences of anxiety or panic • Faulty beliefs about coping strategies (e.G., Safety behaviors) • Faulty beliefs about CBT (e.g., treatment is designed to bring on panic attacks) Behavior Therapy Class
