This is how exercise works for (against) Alzheimer’s

A study by a Massachusetts General Hospital (MGH) research team finds that neurogenesis -inducing the production of new neurons — in the brain structure in which memories are encoded can improve cognitive function in a mouse model of Alzheimer’s disease. Their investigation shows that those beneficial effects on cognition can be blocked by the hostile inflammatory environment present in the brain of patients with Alzheimer’s disease and that physical exercise can “clean up” the environment, allowing new nerve cells to survive and thrive and improving cognition in the Alzheimer’s mice.

The researchers, studying rodent models, found that the more complex a memory is, the greater the risk that it will be compromised by a high-fat diet. The study demonstrates that such a diet causes deficits in episodic, spatial and contextual memory.

Episodic memory (those that provide context, such as ‘what, when, who and where’) is important in humans as it is one of the first types of memory to be compromised in Alzheimer’s disease and deficits in this memory type have been linked to a higher body mass index in young adults.
