Aphasia Press ReleasesStudy Links Progressive Aphasia Syndrome to Prion Gene
Monday, Nov 28, 2005
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. The researchers also
looked at the prion protein gene in people with Alzheimer's disease and amyotrophic lateral sclerosis (ALS or Lou Gehrig's
disease) and did not find any association with specific gene variants in those disorders.
