Concentrations of amyloid beta protein in cerebrospinal fluid of patients with Alzheimer's disease.
Deposition of fibrillar amyloid beta protein (A beta) is increased in brains of patients with Alzheimer's disease. Concentrations of A beta were measured in cerebrospinal fluid with an enzyme-linked immunosorbent assay in 10 neurological patients free from neurodegenerative disease, 28 patients with Parkinson's disease, and 18 patients with probable Alzheimer's disease. Levels of A beta in cerebrospinal fluid were not significantly different among these groups. This observation suggests that concentrations of soluble A beta in cerebrospinal fluid as measured in this study do not reflect the amount of fibrillar, aggregated A beta in the brain of patients with Alzheimer's disease.
