Perception is a subjective phenomenon and, when it comes to medical conditions, it is clear that each person has their own perception of their ailment. Notably, the perception can be positive or negative and can have an immense impact on a patient’s adherence to treatment, recovery, and associated outcomes.[1-3] The association of a patient’s mindset with their clinical outcomes has been demonstrated in a number of conditions, including myocardial infarction, rheumatoid arthritis, type 2 diabetes mellitus, chronic kidney disease, head and neck cancer, and mild traumatic brain injury (mTBI).[1,2]

Importantly, it has been suggested that perception may be shaped by the terminology clinicians employ to describe the illness.[3] Whereas the terms concussion and mild traumatic brain injury are often used interchangeably in the medical community, the clinical appropriateness of the nomenclature continues to be debated.[4] The terms may convey altered messages to patients, and it has been argued that only concussion communicates the transient nature of impaired neurological function.[4] A negative illness perception in mTBI patients results in increased risk for persistent symptoms, and the term concussion, in contrast to mTBI, is strongly predictive of earlier hospital discharge and earlier return to school.[2,5]

Frostholm and colleagues[6] suggest that discussions with patients about their ideas of an illness could help resolve misconceptions and reduce the risk of health problems developing into chronic conditions. Despite the lack of consensus, the potential influence of terminology on patient expectations and outcomes should not be underestimated. Reiterating these concepts to medical trainees, in the context of mTBI and the conditions listed above, could be an important intervention to counteract negative illness perceptions and thus improve outcomes.
