Alzheimer’s risk rises when amount of deep sleep falls, study suggests

A new study found that not getting enough time in deep sleep can hasten the deterioration of brain parts linked to Alzheimer's disease.
Lead study author Gawon Cho stated that deficits in deep sleep can shrink brain parts linked to cognitive decline.
Over one in three American adults do not receive enough sleep, according to the US Centers for Disease Control and Prevention.
Preventive neurologist Dr. Richard Issacson supports the study’s findings, emphasizing the importance of improving sleep for Alzheimer's risk reduction.

Both slow wave and rapid eye movement sleep contribute to emotional memory consolidation

Sleep supports memory consolidation, but the specific roles of different sleep stages in this process remain unclear. While rapid eye movement sleep (REM) has traditionally been linked to the processing of emotionally charged material, recent evidence suggests that slow wave sleep (SWS) also plays a role in strengthening emotional memories. Here, we use targeted memory reactivation (TMR) during REM and SWS in a daytime nap to directly examine wh…

JCI Sleep-wake variation in body temperature regulates tau secretion and correlates with CSF and plasma tau

Sleep disturbance is bidirectionally associated with an increased risk of Alzheimer’s disease and other tauopathies. While the sleep-wake cycle regulates interstitial and cerebrospinal fluid (CSF) tau levels, the underlying mechanisms remain unknown. Understanding these mechanisms is crucial, given the evidence that tau pathology spreads through neuron-to-neuron transfer, involving the secretion and internalization of pathological tau forms. Her…
