Out of 51 cases 44 had probable /possible Alzheimer’s disease (AD) 03 had affective disorder with cogni-tive impairment (pseudo dementia), 04 patients had affective disorder without cognitive impairment. Among probable / possible cases of AD 23 (52.27%) had multi infarct dementia (having history of past cerebrovascular disease), same sta-tistics among Parkinson’s patient’s i.e. diagnosis was Parkinson’s disease with memory impairment were 18 (40.90%) followed by alcoholic dementia in 03 (6.8%). There was no definite Alzheimer’s disease case in this study.
