Abstract

Introduction: With the rising proportion of the elderly in India, the burden of neuropsychiatric conditions and cognitive impairment is escalating. Methods: Baseline data of cognitively healthy subjects ≥45 years of age, from two longitudinal, aging cohorts in rural (n = 3262) and urban (n = 693) India, were used to calculate prevalence of depression, early-life stressful events, stroke, head injury, and cognitive impairment. Results: Depression prevalence was significantly higher in rural than urban subjects, with female preponderance in both groups. Early life stressor (parental death) and head injury were significantly more common in rural than in urban India, whereas stroke was more in urban India. There was no significant difference in overall prevalence of cognitive impairment between the rural and urban cohorts; however, women had higher prevalence than men in rural, whereas this was reverse in urban subjects. Depression and stroke were significantly associated with cognitive impairment in the rural cohort. Discussion: Longitudinal assessment of these neuropsychiatric conditions, with parallel cognitive monitoring, will help identify their causal relationship with dementia.
