A possible reason for the increase is that heart conditions may raise dementia risk. Some medications, like those for high blood pressure, are also given for early cognitive decline symptoms, making the connection harder to understand. Each of these associations will need to be investigated further before conclusions are drawn.

Experts said that ‘cardiorespiratory fitness’ could be used as a predictor for thinking and memory problems in older age.
