Cognitive health

A 26-week randomized trial in Bengaluru tested a yoga-based lifestyle program across multiple healthy-ageing domains. It stood out because it combined functional outcomes with biomarker signals and explicit trial reporting standards.

This pilot randomized trial tested a multimodal package against health-awareness control in older adults with subjective cognitive impairment. The results support early-stage, multidomain prevention before more severe decline sets in.

This Goa-based randomized trial evaluated a task-shared prevention model for late-life depression and showed why lay-counselor delivery is a credible preventive option for older adults in primary care-linked settings.

This institutional randomized trial used a structured multimodal package and reported improvements in depression, self-esteem, and quality of life over follow-up.

This block-randomized trial in old-age homes found that yoga can improve sleep and quality of life, strengthening the case for low-cost behavioral programming in residential elder care.

This review aggregates decades of Indian data on late-life depression and shows how much measured prevalence shifts with tool choice and study setting.

A randomized trial in residential care homes suggests yoga may improve several cognitive domains in older adults. It adds to the report's view that low-cost movement-based interventions may help both physical and cognitive ageing.

This trial reported quality-of-life gains when occupational therapy was added to standard treatment. The report treats it as a pragmatic non-pharmacologic way to reduce functional decline and caregiver strain.

This follow-on occupational-therapy trial reported improvements across function, mood, cognition, and quality of life. It is one of the clearer examples in the report of a non-drug intervention with multiple patient-centered outcomes.

This comparative study suggests structured day-care attendance may support better mental health and quality-of-life outcomes in rural older adults. It gives the report a real-world community model beyond clinic-based interventions.

A PHC-linked geriatric club combined discussion, social activity, and structured engagement and reported better depression and MMSE scores after six months. It is one of the report's clearest low-cost primary-care-adjacent models.

This LASI-based study shows how much case counts can shift depending on which depression scale is used, which matters directly for screening programs and capacity planning.

Observer-blinded RCT evidence in Punjab elders aged 65+ focused on paper-pencil cognitive training vs square-stepping mind-motor training and tracked cognition and iadl changes. Registered, low-cost training options make this a strong practical fit for cognitive-health prevention.

This study supports scalable depression screening in Malayalam-speaking older adults by validating a locally usable version of the GDS-30.

This paper validates Hindi versions of the GDS and PHQ for older adults, improving the quality and consistency of screening in Hindi-speaking settings.

This study validates the WHO-5 as a low-burden first-stage depression screener for older adults in community settings in India.

Cross-sectional evidence in Hyderabad homes for aged focused on vision screening as cognition-risk marker and tracked visual impairment and cognitive impairment relationship. Supports integrated screening that connects visual and cognitive risk rather than treating them separately.

This screening study supports earlier identification of auditory processing difficulty in older adults with hearing impairment, which can shape referral and rehabilitation pathways.

This observational study adds mechanistic support for hearing screening and early rehabilitation as preventive levers for later-life cognitive decline.

This LASI-based study quantifies how many older adults have depression symptoms without diagnosis, making the case for routine or targeted screening in primary care.

This rural Ballabgarh study links depression in older adults to inactivity, chronic disease burden, sleep problems, and hearing impairment, which are all clinically actionable clusters.

Clinical trial evidence in India older adults with mild cognitive impairment focused on integrative intervention and tracked cognition and biomarkers. Targets progression prevention and includes biomarker-aware trial thinking, though details still need careful review.

Cross-sectional evidence in Semi-urban Kerala elders aged 60+ focused on integrated screening for cognition and fall risk and tracked fall-risk prevalence and associations. Supports a more integrated geriatric-screening model instead of siloed risk checks.

Controlled intervention evidence in India older adults focused on trataka practice and tracked cognitive outcomes. Culturally familiar and scalable, though the evidence base is smaller than for the best trials.

Clinical study evidence in India older adults with Alzheimer’s disease focused on yoga intervention and tracked clinical outcomes. More decline-mitigation than primary prevention, but still relevant to preserving function and quality of life.
