Sex differences in adult neurogenesis may underlie dementia risk for women. A high fat diet limits the birth and growth of new neurons in adult female, but not male, mice, according to new research published in eNeuro. Further research could inspire metabolism-based preventions and treatments for brain disorders.
Metabolic disorders like obesity and type 2 diabetes are associated with an increased risk for brain disorders ranging from depression to Alzheimer’s disease. The birth and development of new neurons – adult neurogenesis – may be a link between these two types of conditions. The hippocampus, an area of the brain implicated in memory and emotional processes, is a known site of adult neurogenesis.
Robison et al. fed one group of mice a high fat diet and another group a normal diet for eighteen weeks. The high fat diet caused weight gain and high blood sugar in both male and female mice, however, only female mice experienced impaired neurogenesis in the hippocampus. The female mice on the high fat diet had fewer newborn and developing neurons, while male mice on the high fat diet had the same number of new neurons as the control mice. This finding offers additional insight into why women are more at risk for greater cognitive decline during Alzheimer’s disease and depression.
Receiving a diagnosis of Alzheimer’s disease or another type of dementia can bring mixed and complex emotions. For some, it may be a relief that there is finally an explanation for symptoms....

Scientists have collected plenty of evidence linking exercise to brain health, with some research suggesting fitness may even improve memory. But what happens during exercise to trigger these benefits? New UT Southwestern research that mapped...
