    My dad used to exercise 3-4x a week and always took his vitamins. At around his early 70s he stopped working out when his gym closed and it wasn’t easy to drive out of his way to another before work every day. Within 5 years he had to quit his job because of his deteriorating cognitive function and by 78 he was in a wheelchair because he had a tendency to fall and lose balance. After falling at the top of the stairs twice we had to ban him from his own room on the second floor to avoid a fall down 2 flights of stairs. He died shortly after his 80th birthday. “Age related dementia” but never outright called Alzheimer’s. Also possibly Lewey body syndrome.

    Complex organisms (hydra, us and everything in between) have specialized cells. All the cells have the same genes but each specialty has its defining epigenes. The evolution of complexity evolved when a gene (Hox) evolved that when the cell divides at a specific time (or after a certain number of divisions) gives 2 daughter cells that differ in their epigenes at a specific location, producing a cascade that gives 2 different cell lines. We do this many times, hydra only does it a few. Because hydra does this so few times it has also evolved the ability to reverse it, then reinstate it to regenerate any lost part and reproduce by budding.

But then I feel like my mental faculties have suffered over the last couple of years as well, so maybe it’s just worse when you’re in your 80s. How do I tell the difference?

    Another possibility is that finding signs of the mental decline that comes with Alzheimer’s may be particularly hard in people with autism, especially for those who might already be functioning at a lower intellectual ability, Westmark says. “It’s a really novel idea, that autism could be protective,” she says. However, she adds, “I think that someone could probably write an equally convincing paper on the opposite.” This channel reveals that more dendritic branches are good against dementia. Autistic patients are born with more dendritic processes than normal people. This discovery really connects the dots about the role of neural dendrites in dementia.

    Though the tentacle end is called the "head," it is misleading to what is usually thought of as a "head." "Hydras have two significant structures on their body: the "head" and the "foot". When a Hydra is cut in half, each half will regenerate and form into a small Hydra; the "head" will regenerate a "foot" and the "foot" will regenerate a "head". If the Hydra is sliced into many segments then the middle slices will form both a "head" and a "foot"." "The nervous system of Hydra is a nerve net, which is structurally simple compared to more derived animal nervous systems. Hydra does not have a recognizable brain or true muscles. Nerve nets connect sensory photoreceptors and touch-sensitive nerve cells located in the body wall and tentacles." Wikipedia

    There's a well-documented study in a convent population (I believe in PA) in which the nuns had an inordinately high amount of plaques and tangles, yet none (pun not intended) showed any signs of mental health problems; on the other hand, there are some patients with a dx of Alzheimer's who have the brain autopsied after death (obviously) that don't show either change ... I think that one-third of people diagnosed with Alzheimer's don't show plaques or tangles either as found on observational studies (or, that's the number around 1995) ... so your comment about doctors not knowing the cause certainly is correct.

    Simple, if we don't know the actual cause of a disease, how can we say that " this person would have gotten Alzheimer's if not for ____". Plus, big data studies are also hard to do quickly. We've only started getting a sense of the potential causes of Alzheimer's in the past decade, let alone any sort of ability to say who is at risk beyond guessing from family history.

    We don’t actually have algorithms doing large scale searches like that because stats are hard. This paper is a collection using a case-control format which is, in the grand scheme of things, quite a weak study design. Studies like this have a easy time finding associations, and a hard time controlling for confounding variables. So for example, it’s possible that this association only exists because people with erectile disfunction have other health problems which could lead to death prematurely to the age they would’ve developed Alzheimer’s. But you’d not be able to know that information due to the limits of the study design. Edit: and I should add, the abstract blatantly states that the investigators are aware that their result is not indicative of a causative relationship, and they recommend a randomized control trial. This is nice and all, but VERY unrealistic; RCT’s are just too inefficient for rare outcomes like Alzheimer’s, it’s almost certain that this is one of those times where you see a video about an exciting development, but never hear about it again.
