Alzheimer's & Dementia

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

Wearable forehead patch tracks brain-water shifts during sleep at home

A soft, wireless NIRS forehead patch tracked water-sensitive brain signals during 16 overnight home sleep recordings in four healthy men. The signals changed with EEG/EOG-defined sleep stages, suggesting a new way to study sleep-linked brain-fluid dynamics, although the device did not directly measure CSF flow or glymphatic clearance.
