A study conducted at Charles University with collaboration from researchers at King’s College London and the University of Exeter found that certain behaviors in men over 50, known as mild behavioral impairment, are associated with a higher risk of dementia. A summary of the study published in Neuroscience News indicates that these behaviors are in five areas:  social withdrawal or apathy; mood changes, including anxiety; increased impulsivity; social inappropriateness; and holding false beliefs.

The same behaviors in women do not have this same, strong association, and the study is the first to identify gender differences in markers for cognitive decline.
