Background: Although objectively measurable memory impairments typically resolve within weeks after sustaining a concussion, many people continue to perceive memory problems one year later. There are no known effective treatments for this condition. A promising new approach may be to target psychological mechanisms that perpetuate excessively negative perceptions of memory ability.~Methods: A pilot randomized controlled trial to evaluate the feasibility of a new cognitive behavioural therapy (CBT)-based treatment program specifically designed to improve persistent memory complaints after concussion. The main inclusion criteria will be (i) concussion in the past 6 to 24 months, (ii) research diagnosis of Functional Cognitive Disorder. Participants will be randomized (1:1) into one of two groups: CBT or cognitive rehabilitation. Individuals in both groups will participate in 11 x 50-minute sessions delivered over Zoom videoconference, co-facilitated by clinical psychology graduate students under the supervision of a registered clinical psychologist.~Aims: To evaluate the feasibility and potential efficacy of CBT for functional memory symptoms after concussion.~Approach: Prespecified feasibility criteria on recruitment, patient-perceived credibility of treatment, patient adherence to treatment, therapists' compliance with the treatment protocol, and retention will determine the success of the pilot trial. The investigators further hypothesize that CBT will be associated with greater reductions in memory concern compared to the control intervention.~Implications: The results of this pilot study will inform a larger, more definitive clinical trial focused on testing efficacy.
This study aims to evaluate the feasibility of novel cognitive behavioural therapy (CBT)-based intervention designed to improve functional memory symptoms after concussion. Participants will be randomized to CBT or an attention-matched control intervention (cognitive rehabilitation). The primary outcomes for this trial are feasibility metrics, including recruitment, patient-perceived credibility of treatment, patient adherence to treatment, therapists' compliance with the treatment protocol, and retention.
