Cognitive capacity is a person’s ability to process thoughts which primarily refers to things like memory, the ability to learn new information, speech, and reading comprehension. Ageing is being increasingly recognized as a serious global concern and frequently it is associated with impairment of cognitive capacity. This cross-sectional study was carried out from January to December 2014 to assess the level of cognitive capacity among 221 elderly in Zigatola area of Dhaka city. The elderly of both sexes have been covered in this study. Data were collected by using semi- structured questionnaire and through face-to-face interview. The level of cognitive capacity was measured using Folstein’s Mini-Mental State Examination (MMSE). The mean age of the respondents was found 67.03±5.509 years. Most of the respondents 86.9% were male, 88.7% were married, 39.8% were service holders, and 27.3% had secondary level of education. Average monthly family income of respondents was Tk. 41910±23949. By different domains, mean score of the orientation capacity was 8.52±1.35 while it was 2.77±0.508 in immediate recall capacity, 3.305±1.327 in calculation and attention capacity, 1.32±1.018 in recall capacity and 8.52±0.90 in language capacity. Cognitive capacity was normal in 65.2%, borderline in 25.8% and impaired in 9.0%. Impaired cognitive function was significantly higher (16.7%) in very old age than old (10.8%) and young old age (8.4%), (χ2 test, p=0.002). Impaired cognitive function was higher (17.2%) in females than males (7.8%). It was also significantly higher (27.3%) in secondary level education group (χ2 test, p<0.001). Impaired cognitive function was significantly higher (23.5%) among housewives than service holders (4.5%), (χ2 test, p<0.001). Cognitive impairment was significantly higher (14.9%) among lower income group (χ2 test, p<0.001). The level of cognitive capacity remains a common problem among the elderly population. The problem will assume added importance and impact on the society which suggests that elderly need more support from family as well as society and country to improve the level of cognitive capacity.
