A study published in the journal Brain found that poor sleeping can increase levels of proteins, beta-amyloid and tau, involved in Alzheimer’s disease. The data suggested that in some participants when their slow wave sleep was disrupted on average their levels of beta amyloid increased by 10 %. Interestingly, the duration of sleep did not affect beta amyloid, but did increase the levels of tau. Thus, the study showed that poor quality sleep could lead to an increase of beta amyloid and tau causing the risk of plaque to build up in the brain and eventually increasing a person’s risk of Alzheimer’s disease.
