Mental workouts add to brain power

To prevent declining brain power one mental exercise consistently makes a difference.

A review of the best evidence for interventions to prevent declining brain power finds that only one mental exercise consistently makes a difference.

The analysis of clinical trial results for assorted drugs,supplements and activities still can’t say,however,whether the brain training programmes that do seem to sharpen mental function also improve people’s daily lives or lower their risk of developing dementia.

“All we know is you will do better on certain (cognitive) tests. Whether that delays dementia remains to be seen,” said Dr Raza Naqvi,the study’s lead author and a researcher at the University of Toronto.

To see whether any approach fits that bill,or at least seems promising,Naqvi and his colleagues gathered results from all the randomized controlled trials they could find comparing the mental functioning of adults given a particular treatment to others who received no intervention.

Among drugs,hormone therapy,physical exercise and mental training,it was found that only the last yielded positive results every time.
