Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF OCTOBER 19 2025
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

It's important to note that dementia symptoms possibly start as early as age 30. Just very mild.
And some of the hallmark early symptoms is a lack of motivation and difficulty with multi step procedures.
It's likely people struggling to be motivated to cook or find it difficult to prepare a meal turn to frozen dinners because they are much easier to cook.
Sleeping disruptions also associated with dementia. It's normal to sleep a little less at night as we get older but sleeping only 5 or 6 hours a night isn't really normal. As you can imagine, reduced sleep creates more day-time fatigue. Further reducing motivation and attention to prepare meals.
Whenever I see these kinds of studies linking some behavior or activity with dementia, it's always important to ask which came first. Is there a interaction effect or a one way effect.
Similar research:
Claims like dental plaques and tartar being associated with dementia.
Is it :
Someone's poor dental hygiene causes dementia or dementia causes poor dental hygiene ?
I acknowledge that processed food isn't very healthy. Probably increases risk for a lot of gastro problems and nutrition deficiency.
But in this case, probably the dementia was independent.
Pretty strong evidence that Alzheimer's starts very early in life. Only shows cognitive symptoms much later.
