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

65. Are they largescale longitudinal studies spanning decades?

If not, then I have one word: inconclusive

Unless you're claiming that diet/exercise are the only differences affecting twins over the course of sixty or seventy years, then you'd need to explain how you account for those other variables. Factors such as stress, sleep patterns, pathogens, environmenal toxins, etc. Are all of these accounted for? Over what period? The length of the trial? And do these studies clearly indicate that diet/exercise are the principal causative factor in twin-pairs?

I admit that such longterm studies might be commonplace, but Google returns very few results pertaining to longterm studies of more than a few hundred individuals lasting more than 20 years or so. For a disease likely decades in the making, such studies strike me as interesting but inconclusive.


Healthy diet and exercise are worthy pursuits in their own right, but it's cruel and irresponsible to offer the false hope that they will mitigate or delay the onset of Alzheimer's.
