Prevalence of subjective cognitive decline and its association with physical health problems among urban community dwelling elderly population in South India
INTRODUCTION
No studies in India have explored subjective cognitive decline (SCD), a hallmark of stage II of preclinical Alzheimer's disease. This study aims to assess the prevalence and correlates of SCD in a South Indian, urban, elderly population.
METHODS
We screened 403 individuals 60 years of age and older using the Subjective Memory Complaints Questionnaire (SMCQ) and measured objective cognition with the Montreal Cognitive Assessment (MoCA). Physical health parameters were evaluated for all participants.
RESULTS
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).
DISCUSSION
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.
期刊介绍：
Alzheimer's & Dementia is a peer-reviewed journal that aims to bridge knowledge gaps in dementia research by covering the entire spectrum, from basic science to clinical trials to social and behavioral investigations. It provides a platform for rapid communication of new findings and ideas, optimal translation of research into practical applications, increasing knowledge across diverse disciplines for early detection, diagnosis, and intervention, and identifying promising new research directions. In July 2008, Alzheimer's & Dementia was accepted for indexing by MEDLINE, recognizing its scientific merit and contribution to Alzheimer's research.
