Most people with a rare type of dementia called primary progressive aphasia (PPA) have a specific combination of prion gene variants, a new study shows. The study is the first to link the prion protein gene to this disorder. It was funded in part by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health (NIH), and appears in the December 2005 issue of the Annals of Neurology.[1].
