Sleep history predicts late-life Alzheimer’s pathology

Your sleep history during middle age may predict Alzheimer's pathology later in life. A decrease in sleep quality between 50 and 70 years of age is associated with higher levels of tau and amyloid beta in the brain. Changes in brain activity and quality of sleep could be a biomarker for Alzheimer's disease.

Researchers Find Human Infant Brains and Bodies Are Active During New Sleep Stage

Infants produce sleep spindles every 10 second, whether in REM or non-REM sleep. Sleep spindles and twitching are synchronized, allowing for twitch reactions to occur during non-REM sleep in infants.

NMDA receptors may link psychosis and sleep deficits

NMDA receptor hypofunction is involved in the reduction of sleep spindles and delta oscillations, which appear in the brain during deep natural sleep. Findings confirm the role NMDA receptors play in sleep disorders that accompany psychotic states.
