Seventy-two hospitalized psychogeriatric patients, with an average age of 73 years, were classified into 3 diagnostic categories. There were 20 patients with dementia of the Alzheimer type (DAT), 29 patients with vascular dementia (primarily multiple infarct dementia, MID), and 23 patients with various other psychiatric diagnoses. Patients were assessed by computed tomography (CT) and single photon emission computed tomography (SPECT). No specific correspondence between the SPECT results and the clinical diagnoses were found. The bilateral parietal-occipital pattern, typical of DAT, was found in only one DAT subject. CT and SPECT were equivalently sensitive in finding brain pathology, but both CT and SPECT appear to have little value in differential diagnosis in psychogeriatric patients outside of documenting the site and severity of the brain pathology. The most reliable method of diagnosis for dementia, particularly the Alzheimer type, appears to be the standard clinical assessment.
