Anxiety and the menstrual cycle in panic disorder.

Nineteen females with panic disorder were studied using daily prospective home diary ratings of various general health related items, a short anxiety self-rating scale, a survey of late luteal phase dysphoric symptoms, as well as a record of the number and severity of panic attacks. The subjects collected information for 60 consecutive days, and information regarding 30 menstrual cycles was available for analysis. Overall, subjects retrospectively reported increases in their anxiety symptoms during premenstrual days, but this was not demonstrated consistently on daily prospective ratings.
