Panic disorder, an intense exacerbation of anxiety accompanied by a va
riety of physical symptoms, is twice as common among women as among me
n. Onset is bimodal (teens/20s and mid-30s/40s), 50% of cases are acco
mpanied by agoraphobia, and the etiology is probably multifactorial. T
reatment in the primary care setting includes pharmacologic (selective
serotonin reuptake inhibitors) and cognitive-behavioral intervention.
Medication is initiated at low doses, and the drug-evaluation trial i
s of 6 weeks duration. Psychiatric referral is helpful in nonresponder
s and in those with comorbid psychiatric conditions. Outcome varies, w
ith most patients experiencing relief with treatment. For some people,
however, the disorder is chronic, with ongoing exacerbations and remi
ssions.
