Great News! Alzheimer's breakthrough hailed as 'turning point'

[Bernardo de La Paz]

95. Your post also has an internal logical contradiction:

First you say that mental stimulation doesn't do anything for amyloid plaque and then you say that amyloid plaque may not be the cause. From that you conclude that mental exercise is not a cure.

Well, duh,

1) Nobody in this thread, especially not me, is calling diet or mental exercise a "cure".

2) Getting trapped in the "cure" / "not a cure" mindset like your post exhibits is binary thinking. It is the fallacy of the excluded middle. It dismisses that diet helps slow down the progression and helps prevent or delay the onset in a statiscally significant way.

3) Even if we assume you made a clumsy error in writing, and that you meant to write more clearly so that you would not exclude the middle, your logical chain of reasoning is faulty.

If amyloid plaque is only an indicative side effect of the disease (as you imply), then mental stimulation may well have its effect by not affecting amyloid plaque at all and by affecting something more at the root of the cause.

You seem to be confusing correlation with causation.

4) The positive effects that have been found from mental stimulation have been found in behavioral results (better performance) and performance says nothing about plaque or any intermediary route.

Mental stimulation works.

Even better than that, it's fun!
