THE USEFULNESS OF CT SCANNING IN DIAGNOSING DEMENTIA OF THE ALZHEIMER-TYPE

In order to determine the usefulness of Computerized Tomography (CT) s canning in making a diagnosis of dementia of the Alzheimer type, a gro up of patients diagnosed by NINCDS - ADRDA criteria (n = 22) were comp ared to a group of normal subjects (n = 49) using certain defined line ar CT scan measurements. These measurements included specific measurem ents of the temporal lobes (temporal horns). Subjects were classified correctly 91.5% of the time with a high degree of probability. A diagn ostic equation is presented which will allow testing of these methods in a prospective fashion.
