Researchers in the labs of Professor Yu Jintai within the Department of Neurology at Fudan University-affiliated Huashan Hospital and Professor Tan Lan from the Department of Neurology at Qingdao University have discovered that frequent sleepiness during the day, insufficient sleep or too much sleep at night can affect the levels of cerebrospinal fluid (CSF) indicators of amyloid deposition in female patients and thus increase the risk of cognitive impairment. The TCCI®-supported study also found that sleeping 6-7 hours a night can reduce the risk. The research was published in the July 2020 issue of “Alzheimer’s & Dementia”
