Alzheimer’s Insights: Sleeping patterns may be related to Alzheimer’s

Do you get enough sleep? Most adults will say no.  We’ve all seen Dagwood taking his famous sofa naps in the comic strip “Blondie” and have perhaps been envious.

Did you know sleep and dementia have a relationship?  While researchers are not certain of the exact interaction, it’s there.  Does dementia lead to poor sleep or does poor sleep lead to dementia?

Studies have shown growing evidence that during deep sleep, the brain seems to cleanse itself of beta-amyloid and tau.  Increases in these two items are hallmarks of Alzheimer’s and dementia.

What’s not yet understood is if deep sleep – the sleep you have without dreams – helps the brain cleanse itself of these two items, or if sleep in fact decreases the production of these items.

A British study shows that people in their 50’s or 60’s sleeping six hours or less per night have an increased risk of dementia.  However, researchers could not prove a cause and effect for this.

What is clear is that you can help take better care of your brain.  Don’t smoke, eat right, drink in moderation and keep yourself physically and mentally fit.

A good time to get a start on this is in June, which is Alzheimer’s and Brain Awareness Month. There’s more at

You can also help by taking part in The Longest Day.  It’s held on the date of the summer solstice – this year, June 20th.  It’s aimed at starting and continuing the conversation about brain health.

There’s still plenty of time to join The Longest Day events for June.
