The size of part of your brain could indicate your risk of cognitive impairment

A larger brain volume could indicate a reduced risk of memory decline according to research published in the open access journal Alzheimer's Research and Therapy.

The preliminary study of 226 people indicates that an association between brain volume, in particular the size of one's hippocampi, and one's memory, could predict one's likelihood of cognitive impairment, such as dementia. Further research is needed to confirm what exact role the hippocampi play in the onset of cognitive impairment.

Our hippocampi, a pair of seahorse looking structures located in the left and right sides of the brain, are responsible for forming new memories. When these are impaired, as in Alzheimer's disease, it becomes difficult to remember recent acts or events. Previous studies have suggested that their size could be used as a standard assessment, indicating those at increased risk for the development of Alzheimer's disease.
