Daytime napping and Alzheimer's dementia: A potential bidirectional relationship
- WalterBright 5y agoThis isn't new, a decade ago I read that Alzheimers patients sleep quite a bit more than normal. I suspect this is the brain trying to rid itself of what is causing the Alzheimers.

- hindsightbias 5y agoSo is there a higher rate in EU countries with afternoon naps?
- ILMostro7 5y agoIs there a reference to siestas?
- tluyben2 5y agoNot many people use their siesta to actually nap though anymore: maybe in august when it is 40+ Celcius it goes up but that is a few weeks a year and tourists basically pass out then too from too much booze and food around siesta time.
- inopinatus 5y agoSleeping in your car isn’t quite as popular in Europe.
- qiskit 5y agoWondering this myself. I remember reading ( not too long ago ) that europeans lived longer and had better mental health because they napped more than americans. Wasn't it even encouraged to take naps at work for better mental function.
- tinyhouse 5y agoThe research about napping is conflicted. If you like napping don't worry about it too much. Do what works for you. We know there are many factors here. Maybe older people who nap more have less hobbies and use their brain less (e.g., if you still work or volunteer daily you don't have time to nap). Maybe they take more pills and have other health issues that make them more sleep during the day. Who knows. Too many possibilities.
- aurora72 5y agoA drug called Alprazolam or better known as Xanax drives the patient who takes it to sleep excessively during daytime. I've got two acquaintances, who take those pills and they sleep quite often during the day.

- jamesrom 5y agoAt least he contributed something to the conversation. There's no need to be rude.
- thevagrant 5y agoIt's interesting and is something that crosses my mind when considering any kind of medication. what are the long term consequences of taking this? I haven't taken xanax but I guess present day quality of life (for some) may be more important than unforseen long term consequences. It would be nice to know for sure though.
- quickthrowman 5y ago> what are the long term consequences of taking (alprazolam)? Drug dependence and an inability to cope with stress/anxiety without the drug. Benzodiazepines are useful to alleviate panic attacks, but they’re not a great way to manage general anxiety, due to the drawbacks. Making lifestyle/personal/environmental changes and removing stressors is the key to managing long term anxiety for most people, not drugs.
- hyperpallium2 5y agoIs there any evidence here beyond correlations?
- dakial1 5y agoThis was my doubt also. Couldn't find anything indicating a causal link, so this is not so useful in the end
- avazhi 5y agoClassic correlation =/ causation problem. If you are napping during the day, it's probable that you didn't sleep well or enough the night before. We know that, amongst other things, sleep is absolutely necessary to clear out toxins that build up in the brain during one's waking hours, and we know that people who get less than 7 hours of sleep per night are themselves at a significantly heightened risk of neurodegenerative diseases. The studies behind that particular stat strongly suggest causality - I don't have the paper handy atm but they've done experimental studies where they've taken the experimental group of rats and prevented them from sleeping, as opposed to this study which is simply observational. With the group of rats that are chronically sleep deprived by the researchers, they are significantly more likely to develop neurodegenerative disease. I wouldn't draw much from this paper, aside from being astounded that a team of scientists wrote and published it without apparently seriously considering the basic and frankly obvious causality issue that an average first year science student would be expected to notice.
- pengaru 5y ago+1 My father snored loudly all my life and as he grew elderly (and sleep apnea awareness/treatments increased) it became glaringly obvious he suffered from sleep apnea and would literally choke himself awake repeatedly throughout the night. Of course he had a tendency to fall asleep watching tv for lack of any restful sleep overnight. I think it goes without saying there was a psychological effect, it's too complicated with many factors I don't even attempt to link specific effects. But I'm confident the sleep situation wasn't doing him (and his family) any favors.

We know that? Because meta-analyses suggest that at even 6 hours you have less all-cause mortality than at 8 hours of sleep[0] and I'm yet to see systematic reviews/meta-analyses suggest that going under 7 hours is as bad as pop science claims. 0. https://guzey.com/files/books/why-we-sleep/shen2016.jpg https://guzey.com/files/books/why-we-sleep/shen2016.jpg from Shen X, Wu Y, Zhang D.

- racecar789 5y agoNap rooms at work are pretty common in China.
- thisNeeds2BeSad 5y agoSo sleep apnoe causing tired people with not properly flushed brains causes alzheimers.. the conclusing is final snorring is murder..
- quassy 5y agoConsidering apnoe and in general bad sleep is really bad for your heart, yes.
- thevagrant 5y agoI wonder if ADHD has any relationship to alzheimers later in life. I've spoken with many people with adhd who refer to adhd related fatigue as "narcolepsy lite".
- user_named 5y agoEveryone naps at noon in China.
- m0llusk 5y agoThis isn't about siesta which is common in many countries. This is about accumulating increases in the amount of time spent sleeping during the day.
