Timing of onset of cognitive decline: results from Whitehall II prospective cohort study | BMJ - [Papers of Interest]
I’m pretty sure, anecdotally speaking, that if one was to ask a room full of 65 year olds if they had noticed any change in their memory over the past few years most would say they had. I’m equally sure that if one asked a room of 45 year olds the same question the answer would be quite different. The findings of a recent study have however radically suggested that there are significant decreases in cognitive function seen in men as early as 45-49 years of age.
