Frontotemporal dementia: paroxetine as a possible treatment of behavior symptoms. A randomized, controlled, open 14-month study.

Frontotemporal dementia (FTD) represents an important cause for degenerative disruption and is increasingly recognized as an important cause (up to 25%) of degenerative dementia among late-middle-age individuals. The serotoninergic system is tightly bound to frontal circuits, whose degeneration subserves FTD. Patients aged 64-68 years, with a diagnosis of FTD, were randomized to receive paroxetine up to 20 mg/day (n = 8) or piracetam up to 1,200 mg/day (n = 8). At 14 months, the patients treated with paroxetine showed significant improvements in behavioral symptoms, reflected by a reduction of caregiver stress. Side effects were easily tolerable, and there was no dropout. The results are presented with an overview of the literature on the topic.
