However, a team of researchers from Imperial College London has made the exact opposite point, that the ability to flush waste products is actually weakened during sleep. It has been confirmed that if rhythmic brain waves are inhibited, fresh cerebrospinal fluid is not sent and waste products remain. Although there has been an increasing number of studies linking sleep deprivation to the risk of Alzheimer's disease in recent years, it remains unclear whether sleep deprivation causes Alzheimer's disease or whether sleep deprivation is an early symptom of Alzheimer's disease. Another aspect of this study is that it shows that the brain's ability to clear waste products is more efficient when you're awake.
