An epidemiological study of dementia under the aegis of mental health program, Maharashtra, Pune chapter.
BACKGROUND
There has been an exponential growth in the number of elderly population in India. This study aims to determine the prevalence of dementia in an urban center of Pune and to evaluate the corresponding socio-demographic correlates along with psychiatric morbidity in the study sample.


METHODS
The study population in Pune and Kirkee cantonments was selected based on 2001 census data. The number of people over 65 years numbered 6721 and 2145 of them were randomly selected for a door-to-door survey. They were initially administered household questionnaire and then subjected to a screening tool. Each participant underwent a brief mental state examination and data was collected on the basis of a structured proforma. Patients underwent a detailed cognitive profile using subtests from CSI-D (community screening instrument - dementia), which included a Consortium to Establish a Registry for Alzheimer's Disease (CERAD) word list, word fluency and delayed recall. Information pertaining to socio-demographic factors in participants and caregivers, caregiver-burden and behavioral and psychological symptoms in participants too were collected from the questionnaire. Radio imaging investigation was also carried out to quantify the deficit. Statistical Package for the Social Sciences (SPSS) software was used to compute the results.


RESULTS
Findings revealed that prevalence of dementia in the sample population of elderly aged above 65 years was 4.1%. Socio-demographic factors which conferred a statistically higher risk for dementia were identified to be older age, low socio-economic status, low level of education, presence of family history, whereas, marriage was found to be protective. Burden of care was associated with caring for elderly with dementia with increasing severity of dementia. Patients with dementia performed poorly on cognitive test battery. Social network had a protective effect in respect with severity of dementia. On magnetic resonance imaging (MRI) majority of cases of Alzheimer's Dementia (AD) and Vascular Dementia (VaD) were noted to have both gray and white matter involvement.


CONCLUSIONS
Poor awareness is a key public-health problem. Society plays an important role in the ageing process. The withdrawal of the elderly from the previous societal roles,reduction in all types of interactions i.e. shift of attention from outer world to the inner world, reduction in the power and prestige of the elderly enhance aging process. Aging in Indian culture though a disability is much stressful today in Indian culture as in others.
