  • Are you a daytime napper? If so, read this.


    Recently, some new studies released a novel concept in the race to accurately detect symptoms of Alzheimer’s Disease. It’s not forgetfulness, or even misplacing things on a regular basis. Researchers from the University of California, San Francisco (UCSF) are making the new claim it may be frequent daytime napping which may signal the onset of the disease.

    The findings, which appear in the journal Alzheimer's & Dementia, also suggest that an overaccumulation of tau protein triggers these brain changes. In Alzheimer's disease, tau proteins form tangles that disrupt communication between neurons (brain cells) and impact cell health.

    "Our work shows definitive evidence that the brain areas promoting wakefulness degenerate due to accumulation of tau — not amyloid protein [another protein that can become toxic in Alzheimer's disease] — from the very earliest stages of the disease," explains senior author Dr. Lea Grinberg.

    The team found that, in comparison with healthy brains, those affected by Alzheimer's disease had a high level of tau across three regions that are key to staying awake, namely the locus coeruleus, the lateral hypothalamic area, and the tuberomammillary nucleus. Not only this, but these regions had actually lost 75% of their neurons.

    The good news appears to be that if your daily or regular schedule involves a daytime nap, this new research likely does not apply to you. f napping is a part of your routine on a regular basis though, you don't need to worry about taking an afternoon snooze, or mid-morning for that matter. "It only gets worrisome when it represents a change," said Grinberg. "For instance, in some cultures, it is pretty common to nap every day. This is quite okay."
