High-frequency cranial electrostimulation (CES) in patients with probable Alzheimer's disease

In a previous study, low-frequency cranial electrostimulation did not improve cognition and (affective) behavior in patients with probable Alzheimer's disease. In the present study, 2 1 Alzheimer's disease patients, divided into an experimental (n = 1 1) and a control group (n = 10), were treated for 30 mins/day, 5 days/wk, for 6 wks with high-frequency cranial electrostimulation. Similar to the previous study, no improvements on cognition and (affective) behavior were found
