A new study by Oxford University in about 500 persons with existing dementia, if I remember correctly, found that the active group, consisting of moderate and high intensity exercises, had worse memory and brain power. This was despite increases in physical performances.
This suggests that exercises may impair existing dementia.
I have not read the actual study yet and saw this for a moment before I had to drive so I’m posting this here to gather input. I’ve attached several news sites reporting this that I came across in my Google Alerts below:
