Conrad's Return to Work After Head Injury: Information Not Provided

The source text does not specify Conrad's occupation after his head injury, so this question cannot be answered from the given context.

In general, return-to-work after traumatic brain injury (TBI) depends on injury severity, cognitive/physical deficits, job demands, workplace accommodations, and rehabilitation progress. A multidisciplinary team (neurologist, neuropsychologist, occupational therapist, vocational counselor) typically guides the process.
