Memory Boosted a Staggering 50% By These Activities From Childhood

I bet your doctor will not be prescribing these to help your memory post-stroke.  Of course my proprioception is screwed up so my doctor would need to fix that first.

Climbing a tree can improve working memory by 50%, a new study finds. Ask your doctor if the same would hold true for stroke survivors.

The same is true of other dynamic activities like balancing on a beam, carrying awkward weights and navigating around obstacles.

The actual study is here:

THE WORKING MEMORY BENEFITS OF PROPRIOCEPTIVELY DEMANDING TRAINING: A PILOT STUDY

Summary.—The aim of this study was to investigate the effect of proprioception on working memory. It was also of interest whether an acute and highly intensive period of exercise would yield working memory gains. The training group completed a series of proprioceptively demanding exercises. There were also control classroom and yoga groups. Working memory was measured using a backward digit recall test. The data indicated that active, healthy adults who undertook acute, proprioceptively demanding training improved working memory scores compared to the classroom and yoga groups. One possible reason that the training yielded significant working memory gains could be that the training was proprioceptively dynamic, requiring proprioception and at least one other factor—such as locomotion or navigation—at the same time, which may have contributed to the improvements in working memory performance.
