Noise during cognitive tests and older adults' cognitive performance: evidence from India.

ABSTRACT:

Background and objectives

Noise during cognitive assessments may impact cognitive performance and lead to biases in estimates of dementia prevalence, especially in developing regions where optimal test conditions may be harder to ensure. However, evidence on noise during testing and older adults' cognitive performance remains limited. To fill this gap, this study aimed to analyze the role of noise during cognitive assessments in older adults' cognitive scores, using data from a population-based study in India.

Research design and methods

Using data from the second wave of the Longitudinal Aging Study in India-Diagnostic Assessment of Dementia (n = 3,509), we examined the associations between noise during testing and cognitive scores, and whether these associations var
