The LEQ is a questionnaire designed to assess an older person’s cognitive lifestyle. Cognitive lifestyle refers to a person’s lifelong habits of engaging in complex mental activities.
The LEQ divides a person’s life into three stages – young adulthood, middle age and late life stages. Questions about educational, occupational, mental, social and leisure activities are asked in relation to each of these life stages.
Why is Cognitive Lifestyle important?
From a brain health perspective, a number of studies have linked participation in complex mental activities with reduced dementia risk. Mental activity has a number of positive effects on the brain – from the level of the individual cell, to overall brain connectivity and performance.
What’s the LEQ for?
The LEQ is being used in the 4Nations Study to determine how cognitive lifestyle patterns vary in the Australian community and in different populations around the world.
LEQ and the Brain
RNG has found that an active cognitive lifestyle, as measured by the LEQ, predicts a slower rate of hippocampal atrophy in older individuals – see link to paper.
Has the LEQ been scientifically validated?
Yes. We have published our validation study in the following international peer-reviewed scientific journal: M. Valenzuela & P. Sachdev. Assessment of complex mental activity across the lifespan: development of the Lifetime of Experiences Questionnaire (LEQ). Psychological Medicine (2007) 37:1015-1025
