Abstract

For many, symptom resolution occurs relatively quickly after traumatic brain injury (TBI), however some people experience symptoms that can last for months and even years. Apathy is a symptom that can cause disruption after TBI. While cannabis has been suggested to treat several symptoms and conditions related to TBI, given the historical association with apathy, investigation of the relationship is imperative. There is little research in the medical population, with even less in specific clinical samples - this study aims to bridge this gap. 52 participants with symptoms lasting at least 6 months were compared based on the use of medical cannabis (N MC: 24; N non-MC: 18). Self-reported apathy symptoms were examined, as well as resting-state functional connectivity (FC) of areas related to motivation. No differences were found in self-reported apathy symptoms or in FC between regions associated with goal-directed activity.
