Gamma Frequency Sensory Stimulation in Probable Mild Alzheimer’s Dementia Patients: Results of a Preliminary Clinical Trial
After 3 months of daily stimulation, participants with mild Alzheimer’s disease in the 40Hz stimulation group showed less ventricular enlargement and stabilization of the hippocampal size compared to the control group. Functional connectivity increased in both the default mode network and the medial visual network. Circadian rhythmicity also improved. Compared to controls, the active group performed better on the face-name association delayed recall test.
