Abstract
A method is provided for detecting senile dementia of the Alzheimer's type (SDAT) wherein atrophy of the medial temporal lobe of the brain (for example as determined by CT scan) as indicated by a thickness thereof, at its narrowest point, of 11.5 mm or less represents a positive finding of SDAT. In an extension of such method, atrophy of the medial temporal lobe as described above combined with reduced blood flow in the posterior parietal/superior temporal cortex (for example as determined by SPET), represents a positive finding of SDAT.
