A recently published study shines new light on the potential link between lack of deep sleep and the development of Alzheimer’s disease.

When it comes to the proper functioning of the brain’s waste removal system, which works to clear out toxic proteins, not all sleep is the same.

Deep sleep appears to be a key component in helping reduce one’s chances of developing the disease, while lack of deep sleep may increase the risk.

Past research has implicated deep sleep — and lack thereof — as a factor when it comes to the development of Alzheimer’s disease.

At the heart of the matter are toxic proteins, including beta amyloid, which can accumulate in the brain.

The accumulation of these proteins has been associated with Alzheimer’s disease, and disrupted sleep may be a contributing factor.
