To determine the prevalence of AD and other dementias in a rural elderly Hindi-speaking population in Ballabgarh in northern India.
The authors performed a community survey of a cohort of 5,126 individuals aged 55 years and older, 73.3% of whom were illiterate.
Hindi cognitive and functional screening instruments, developed for and validated in this population, were used to screen the cohort.
A total of 536 subjects (10.5%) who met operational criteria for cognitive and functional impairment and a random sample of 270 unimpaired control subjects (5.3%) underwent standardized clinical assessment for dementia using the Diagnostic and Statistical Manual of Mental Disorders-fourth edition diagnostic criteria, the Clinical Dementia Rating Scale (CDR), and National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria for probable and possible AD.
We found an overall prevalence rate of 0.84% (95% CI, 0.61 to 1.13) for all dementias with a CDR score of at least 0.5 in the population aged 55 years and older, and an overall prevalence rate of 1.36% (95% CI, 0.96 to 1.88) in the population aged 65 years and older.
The overall prevalence rate for AD was 0.62% (95% CI, 0.43 to 0.88) in the population aged 55+and 1.07% (95% CI, 0.72 to 1. (...)
