The goal of the present study was to examine possible effects of right median nerve stimulation (RMNS) on memory in patients in a relatively early stage of probable Alzheimer's disease (AD). Seventeen AD patients were randomly assigned to an experimental group (n = 8) and a control group (n = 9) and treated with RMNS and sham RMNS, respectively, for 30 min a day, 5 days a week, for 6 weeks. Neuropsychological tests were used to assess memory processes. The results show that the various aspects of memory did not respond positively to RMNS. A study with a much longer treatment period is suggested before firm conclusions about the ineffectiveness of RMNS on memory in AD can be drawn.
