Overview

The CLSA Memory Study investigates whether information that is collected through CLSA interviews can be used to correctly identify individuals who have memory problems and individuals without memory problems.

CLSA participants who are invited to take part will undergo a medical assessment by a study clinician at one of 11 CLSA Data Collection Sites. The assessment will include questions about medical history and a brief cognitive test that includes answering questions and drawing on paper. The clinician will also complete a neurocognitive examination, which involves assessing participants’ ability to see, observing them move, and listening to them speak.

Participants in the CLSA Memory Study will also be asked to identify a family member or friend to complete an interview by phone regarding the participants’ cognitive health, ability to complete daily tasks and behaviour.
