Good vibrations: tactile stimulation may aid Alzheimer’s treatment

(David Orenstein/ Neuroscience News) –– Researchers discovered tactile stimulation at a frequency of 40 Hz can help in reducing Alzheimer’s disease pathology and symptoms.

The study, conducted on Alzheimer’s model mice, demonstrated improved brain health and motor function with daily exposure to such stimulation for a few weeks.

This study illustrates such stimulation can decrease levels of phosphorylated tau, a protein indicative of Alzheimer’s, and protect neurons from damage and synaptic loss. The finding could open up new possibilities for non-invasive therapeutic strategies in treating neurodegenerative diseases.

The study is the first to show that 40 Hz tactile stimulation can reduce levels of phosphorylated tau, a protein associated with Alzheimer’s, and prevent neuronal death and synaptic loss. (…)
