Topiramate in the treatment of comorbid night eating syndrome and PTSD: a case study.

Comorbid chronic sleepwalking with night eating syndrome and posttraumatic stress disorder were treated with topiramate for eight months in an obese 40-year-old woman. Central nervous system side effects of word-finding and memory difficulties were managed with dosage adjustments to a final dose of 100 mg HS. Treatment led to resolution of posttraumatic stress disorder symptoms, night eating episodes, and sleepwalking episodes, with a weight loss of 70 pounds.
