The strategy suggests a promising approach, the scientists say, for treating symptoms of Parkinson’s disease and other neurodegenerative diseases and disorders, including epilepsy.

Memories may be formed throughout the day, not just while sleeping

Sleep apnea linked to cognitive impairment in older women

Older women with sleep-disordered breathing (SDB) –– the restriction or interruption of breathing during sleep –– are more likely to show cognitive impairment than women without SDB, according to a study led by researchers at the San Francisco VA Medical Center and UC San Francisco.
