New connection between Alzheimer's dementia and Dlgap2

A research team has discovered that Dlgap2, a gene that helps facilitate communication between neurons in the nervous system, is associated with the degree of memory loss in mice and risk for Alzheimer's dementia in humans. When studying post-mortem human brain tissue, the researchers also discovered low levels of Dlgap2 in people experiencing 'poorer cognitive health' and 'faster cognitive decline' prior to death.
