The interim results are for 24 patients that were divided into three groups: a sham stimulation control group, a low-frequency (1 Hz) treatment group and a high-frequency (10 Hz) treatment group. Each subject received treatment over 8 weeks, and the efficacy of the treatment was evaluated both during the trial and over the course of the subsequent 8-week period.
The treatment was well-tolerated by all subjects, with no side-effects, except for one incident involving a sham control subject, which the principal investigator believes to be unrelated to the treatment.
The trial used the Alzheimer's Disease Assessment Scale - Cognitive (ADAS-Cog) test (the main efficacy scale used in Alzheimer's disease clinical trials), as well as additional accepted scales of disease severity (CGI, ADL, CDR) and a quality-of-life scale (QoL Caregiver Scale) to assess the efficacy of treatment. These are the main assessment scales used to evaluate efficacy in the literature... Brainsway's Press Release -
