Scientists have discovered a simple way to slow down memory decline

Regular help to others can be one of the ways to maintain clarity of mind in old age. Scientists have found that even a few hours of good deeds a week are associated with a slower decline in memory and thinking abilities. And the most noticeable effect was observed in people with a hereditary predisposition to Alzheimer's disease. The study was published in the journal Alzheimer’s & Dementia.

Experts studied data on almost 18 thousand people whose health status was monitored for 22 years - from 1998 to 2020. Special attention was paid to carriers of the genetic variant APOE ε4 associated with an increased likelihood of dementia.

The analysis showed that participants who volunteered regularly or helped relatives, friends and neighbors experienced slower age-related cognitive decline. Among those at high genetic risk, severe memory and thinking problems occurred nearly two years later than those who did not participate in the activity.

Notably, the positive association persisted even at less than four hours per week. It didn’t matter if the aid was organized or if it was a matter of daily routine. Scientists suggest that social activity and caring for others may favorably affect brain function, in particular by reducing stress.
