Which factor is most strongly associated with better functional outcomes after moderate-severe TBI?

Which factor is most strongly associated with better functional outcomes after moderate-severe TBI?

• A. Age over 70
• B. Higher best-motor-response scores in early assessment
• C. Presence of comorbidity
• D. Prolonged coma duration

Answer: (B)

Early neurological status, especially how well the patient moves in response to commands or stimuli, is a powerful indicator of how well someone will recover functionally after moderate to severe TBI. A higher best-motor-response score in the initial assessment signals that core motor pathways and related brain networks are relatively preserved, which tends to translate into better long-term functional outcomes, including independence in daily activities. This is because motor responsiveness reflects the integrity of corticospinal pathways and the level of overall brain arousal and organization. When those systems are less disrupted, the brain has a greater capacity for plasticity and recovery, leading to improved functional gains over time. While factors like advanced age, multiple comorbidities, or prolonged coma duration are important prognostic considerations and usually point toward poorer outcomes, they do not predict functional independence as strongly as an early, higher motor-response score.
