While efforts to develop Alzheimer’s medications have so far borne little fruit, new research highlights the therapeutic promise of two non-drug tools: light and sound.
According to a pair of small new studies, exposing Alzheimer’s patients to an hour a day of carefully modulated light and/or sound appears, over time, to slow down the telltale brain degeneration that typifies disease progression.
How? By bolstering and reinforcing a particular type of rhythmic brain wave pattern—called “gamma waves”—which are known to diminish in power among patients battling Alzheimer’s.
“Our completely noninvasive approach to manipulate the power of gamma brain waves works by simply showing mice or…
