The National Institute of Neurological Disorders and Stroke, part of the National Institutes of Health, is looking for individuals to participate in clinical studies. Participating in clinical trials allows you to play an active role in research on the nature and causes of many disorders of the brain and nervous system, and to possibly help physician-scientists develop future treatments. The information below is designed to help you quickly learn about actively recruiting research studies for which you or someone you know may be eligible.


Introduction: In this study, we will use anodal direct current (DC) polarization at 2 mA to treat patients with frontotemporal dementia (FTD). Currently, there is no effective treatment for these patients. Previously, in healthy volunteers, we observed that DC polarization of the left prefrontal area for 20 min safely increases verbal fluency, cognitive processing speed (working memory and attention) and motor reaction speed. Both of these functions are severely impaired in FTD. Objective: We wish to see whether anodal DC polarization of the left prefrontal cortex in FTD patients leads to improvement in verbal fluency and working memory. Design: In this pilot study, we propose to treat six FTD patients for 40 min with anodal and sham DC polarization in a single-blind, crossover design. Outcome Measures: The main outcome measures will be verbal fluency and working memory. If anodal DC polarization produces clinically relevant improvements in these patients this will provide the impetus for a larger trial.

Eligibility Criteria:

INCLUSION CRITERIA: -Six patients referred to the Cognitive Neuroscience Section, NINDS, with a clinical diagnosis of FTD confirmed here, will be selected to participate in the study. EXCLUSION CRITERIA: - Greater than 75 years of age. - Presence of metal in the head other than dental hardware. - Broken skin in the area of the stimulating electrodes. - Any behavioral disorder that makes testing impossible. - Children are excluded, as FTD is not a childhood illness.
