What is the typical prognosis after diffuse axonal injury?

• A. Coma lasting days to weeks with poor prognosis
• B. Rapid full recovery within days
• C. Immediate improvement with healing of axons
• D. No chance of recovery with immediate death

Answer: (B)

Diffuse axonal injury happens when rapid head movement shears axons across the brain, disrupting widespread neural networks, especially in pathways that keep a person awake and connected to the environment. This commonly places patients into a coma that lasts for an extended period—often days to weeks—because the brain’s communication networks are damaged so broadly. Because axons in the central nervous system don’t repair quickly or easily, recovery tends to be limited and prognosis is generally guarded, with many survivors having long-term cognitive or motor disabilities. Rapid full recovery within days is not typical, and while some individuals may regain consciousness after a prolonged coma, complete restoration of pre-injury function is not the usual outcome.
