Neuropsychiatric aspects of concussion

Area of Science:

• Neurology
• Psychiatry
• Sports Medicine

Background:

• Concussion is a prevalent injury in contact sports but also occurs in diverse populations and settings.
• It is frequently undiagnosed as a cause of psychiatric morbidity, particularly without loss of consciousness or direct head trauma.
• Existing literature often equates concussion with mild traumatic brain injury (TBI), hindering a clear understanding of its unique aspects.

Purpose of the Study:

• To enhance psychiatric clinicians' understanding and treatment of concussion-related neuropsychiatric symptoms.
• To highlight the need for a distinct approach to concussion separate from general traumatic brain injury.
• To guide future research directions for improved diagnosis and management.

Main Methods:

• This review synthesizes current knowledge on concussion and its psychiatric implications.
• It analyzes the limitations of existing research that conflates concussion with mild TBI.
• It identifies key areas for future clinical and research endeavors.

Main Results:

• Concussion presents a distinct clinical phenotype with significant neuropsychiatric sequelae.
• Current diagnostic and treatment paradigms are insufficient due to the lack of differentiation from TBI.
• Psychiatric morbidity associated with concussion is often underrecognized.

Conclusions:

• A clear distinction between concussion and traumatic brain injury is essential for reliable clinical outcomes.
• Future research must focus on prospective trials, biomarkers, and targeted interventions for concussion.
• Improved understanding and diagnosis are critical for effective psychiatric management of concussion patients.
