Exercise and social activities cause an important region of the brain to age more slowly. Researchers at the University of Zurich were able to show that in people who are physically and socially more active, the so-called entorhinal cortex loses less thickness as they age. This region of the brain plays an important role in memory, as the University of Zurich (UZH) explained. The cortex, which is around 3.5 millimeters thick, is part of the cerebral cortex and acts as an interface between the hippocampus and other brain regions that are involved in memory formation and retrieval. The thickness of the entorhinal cortex is closely related to memory performance.
The scientists examined the relationships between the thickness of the entorhinal cortex, memory performance and leisure activities in cognitively healthy adults over 65 years of age over a period of seven years. In people who were more physically active at the start of the study and met friends and family more often, the thickness of the entorhinal cortex and thus memory performance decreased less over the seven years. “Physical exercise and active leisure activities are therefore important for brain health and can prevent neurodegeneration in old age,” said study leader Lutz Jäncke. It was also shown that higher memory performance at the start of the study was also associated with less decline. The brain can be trained like a muscle.
