How does sleep help prevent dementia?

This shrinking allows more space between the brain cells, so that beta amyloid and other substances that accumulate during the day can be flushed away.

What causes dementia?

Dementia is caused by damage to or loss of nerve cells and their connections in the brain. Depending on the area of the brain that’s damaged, dementia can affect people differently and cause different symptoms.

Why is sleep important for brain function?

Sleep is important to a number of brain functions, including how nerve cells (neurons) communicate with each other. In fact, your brain and body stay remarkably active while you sleep. Recent findings suggest that sleep plays a housekeeping role that removes toxins in your brain that build up while you are awake.

Sleeping six hours or less per night (short sleep) was associated with impaired cognition, mostly in memory, as well as an increase in amyloid-beta — the protein that can form brain plaque (a hallmark of Alzheimer’s disease).

These two new studies show that the harmful effects of inadequate sleep can start at age 50 (if not earlier), and they can lead to early dementia and death. But the good news is that you can reduce your risk of dementia by simply giving yourself six to eight hours of sleep each night.

Does lack of sleep damage the brain?

At a more advanced level, sleep deprivation can over-stimulate parts of the brain and even lead to permanent brain damage, according to a report on sleep deprivation among students published by The Guardian. “This is because of the brain’s ‘neural plasticity’ – which means its ability to adapt to new situations.
