Prevalence of subjective cognitive decline and its association with physical health problems among urban community dwelling elderly population in South India

Topic: Risk, prevention and care in population studies
Among the participants, 377 (93.5%) reported subjective memory complaints. Of the 26 individuals without SCD, 15(57.7%) had objective cognitive impairment (MoCA <25). A total of 182 participants (45.2%) were identified with SCD. Higher educational attainment was significantly associated with fewer SCD reports and better cognitive performance (p < 0.001). Subjective cognitive decline (SCD) is highly prevalent among older adults. Screening for SCD can help identify individuals at risk for Alzheimer's disease. SCD assessement combined with cost-effective biomarkers that confirms AD will help individuals to be identified for disease-modifying therapies. HIGHLIGHTS: Nearly half of older adults population screened has reported subjective cognitive decline (SCD), highlighting the widespread occurrence of SCD in urban South India. Participants with higher educational attainment had significantly fewer memory complaints and performed better on cognitive assessments. SCD was prevalent even among individuals without major comorbid conditions such as diabetes and hypertension and those who were on regular treatment for metabolic and cardiovascular disorders. Identifying subjective cognitive decline (SCD) can facilitate early and accurate diagnosis of cognitive disorders and help delay progression to dementia. This highlights the importance of developing and implementing improved public health strategies to address these challenges. Further longitudinal studies are necessary to explore the progression of SCD to dementia, focusing on the interplay between cognitive health, biomarkers, and educational factors in the Indian population.

Key findings
- Among the participants, 377 (93.5%) reported subjective memory complaints.
- Of the 26 individuals without SCD, 15(57.7%) had objective cognitive impairment (MoCA <25).
- A total of 182 participants (45.2%) were identified with SCD.
- Higher educational attainment was significantly associated with fewer SCD reports and better cognitive performance (p < 0.001).
- Subjective cognitive decline (SCD) is highly prevalent among older adults.
Why it matters
Subjective cognitive decline was very common in this urban South Indian population, affecting nearly half of participants, and higher education was linked to fewer memory complaints. Screening for subjective cognitive decline may help identify people at risk for Alzheimer's disease, but this study does not test any treatment or prevention.

How this study scored 57/100
Published in a peer-reviewed journal, and it is a longitudinal study following the same people over time. Scored zero for randomised / blinded because the record does not state it. We have no data on senior author's track record, so that was left out: it earned 55 of the 96 points we could judge it on, which is 57 out of 100.
