This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing a new non-invasive device called ATTN201 that uses low-intensity focused ultrasound—harmless sound waves—to stimulate a small region deep in the brain called the centromedian nucleus. Researchers believe activating this region can help your brain's natural cleaning system work better, especially during sleep. The trial aims to see if this treatment is safe and can slow cognitive decline in older adults who have early memory loss and signs of Alzheimer's disease.
Poor sleep speeds up Alzheimer's disease in part because it prevents the brain from clearing harmful waste products like amyloid and tau proteins. Scientists have discovered that sound waves can safely trigger the brain's natural waste-clearing system without surgery or invasive implants, offering a new way to treat early memory loss.

If you enroll, you'll first have an MRI scan so doctors can map your individual brain anatomy and personalize the treatment targeting. Then you'll wear the ATTN201 headset at home on a regular schedule to receive either active sound wave stimulation or a sham (placebo) version—neither you nor the study staff will know which at first. You'll visit the clinic several times for memory and thinking tests, sleep questionnaires, and safety checks. The entire study lasts several months, and you'll work closely with your neurologist throughout.
