Understanding concussion in myalgic encephalomyelitis/chronic fatigue syndrome: Findings from the 2023 National...

Although myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) symptoms (dysautonomia, dizziness, balance impairments) may theoretically contribute to an association with concussion, the nature of this association has not been determined. This study explored the association between ME/CFS and concussion, as well as risk factors for concussion, history of recent falls, and feelings of being dizzy or off balance.

2023 National Health Interview Survey data were utilized. United States adults (unweighted N = 29,373) responded to items regarding sociodemographic factors, ME/CFS status, and history of concussion, falls, and feeling off balance or dizzy. Logistic regression analyses assessed the association between ME/CFS and concussion, falls, and feeling dizziness or balance problems within the past year, adjusting for sociodemographic factors.

Individuals with ME/CFS had 4.89 times greater odds of reporting concussion in the past year compared to individuals without ME/CFS. Individuals with ME/CFS also had 2.86 times greater odds of having fallen within the past year and 5.88 times greater odds of reporting feeling dizzy or off balance in the past year.

ME/CFS status may be associated with concussion status. Healthcare practitioners should improve concussion screening and referrals for reducing concussion risk among individuals with ME/CFS.
