Moderate Physical Activity Increases Hippocampus in Adults with Mild Cognitive Impairment

Older adults with mild cognitive impairment (MCI) who engaged in moderate physical activity had greater hippocampal volume.  Atrophy of the hippocampus is a hallmark of Alzheimer's, therefore these results suggest that exercise can help to stave off Alzheimer's.

At Risk for Alzheimer’s? Don’t Just Sit There! Moderate Exercise Protects the Brain

Individuals at higher risk for Alzheimer's who engaged in little to no physical activity lost 3% of their hippocampal volume after only 18 months.  Those who did moderate physical activity showed no change in the volume of the hippocampus.

Gut Microbiota Reduced in Alzheimer’s

This 2017 study from the University of Wisconsin compared the microbiota of 25 people diagnosed with Alzheimer's and 25 age and sex-matched control participants.  The Alzheimer's group showed decreased levels of "good" bacteria and increased levels of "bad" bacteria.

The Link Between Diabetes and Alzheimer’s

Simple Summary Metabolic syndrome, and type 2 diabetes (T2D) are related disorders that damage (among other things) the brain.  Both conditions contribute to impaired cognitive function, and increase the risk of Alzheimer's. More Detail Metabolic syndrome is characterized by belly fat, elevated cholesterol, elevated blood pressure, insulin resistance, increased risk of blood clots and inflammation.  Metabolic syndrome, if uncorrected, eventually damages the pancreas leading to a decrease of insulin secretion.  "The fall in insulin secretion leading to hyperglicemia occurs as a late phenomenon and, in fact, separates the patients with metabolic syndrome from those with or without overt diabetes."(R) Persons with metabolic disorders are at significantly increased risk for cognitive decline and the development of vascular dementia and Alzheimer’s disease.  Those with T2D are at even greater risk. Into The Weeds Insulin Resistance: Insulin is a peptide hormone produced by the Beta cells in the pancreas which also serve as glucose level monitors. As the beta cells in the pancreas detect increasing levels of glucose (a simple sugar) they step up insulin production. When someone is insulin resistance, their cells are unable to take up glucose, and the result is hyperglycemia (an increase in [...]
