This research aims to examine the connection between adolescent IQ and the subsequent risk of developing dementia in older adulthood.
Longitudinal study design tracking individuals over 67 years
Assessment of adolescent IQ levels
Evaluation of dementia risk in older adulthood
Higher adolescent IQ is associated with a lower risk of dementia later in life
Findings support the significance of early cognitive factors for brain health
Abstract
Adolescent IQ is an early life factor associated with a lower risk of dementia in older adulthood. This research highlights the importance of a life-course perspective on brain health.
