Background: Of the higher mental functions, certain deteriorate earlier than others. The relative deterioration of the different higher mental functions in dementia patients would be of interest to investigate. Aim: We intended to study the status of higher mental functioning in dementia patients. Materials and Methods: Household screening of a randomly selected ward, Musahebganj of urban Lucknow generated 1,216 elderly people aged >55 years. After taking the informed consent to participate in the study, all the subjects were screened using the Mini Mental Status Examination (MMSE) for cognitive disorders. Age and education specific cut-off criteria were used to find out MMSE positive subjects. MMSE positive subjects were assessed in detail using the Cambridge Examination for Mental disorder in the Elderly-Revised instrument. Result: Fifty patients were diagnosed to have dementia as per the international classification of diseases-10 criteria. The study demonstrated that the higher mental functioning especially visual reasoning, ideational fluency, and memory are maximally affected in dementia patients. Conclusions: The deterioration in higher functioning is usually seen in dementia. The mental functioning relates with each other and is interrelated, leading to overall deterioration.
