Abstract
Of 90 aged patients asked to give answers to a 35-item mental status questionnaire, 20 were not mentally impaired, but 34 had mild dementia, 17 moderate dementia, and 19 severe dementia. These results were well correlated with the clinical findings. As dementia develops, the first thing to be forgotten is the awareness of time, place and recognition (in that order). Then the ability to count disappears. As mental oblivion intervenes, the last thing the patient forgets is his/her own name. Patients with mild senile dementia fared better when kept with a similar group than with patients who have moderate or severe dementia.
