You’ll want to build a strong medical foundation with several types of documentation: ER records, and initial CT or MRI scans, follow-up imaging studies, neurological evaluations, neuropsychological testing results, and ongoing treatment records. The specialists who often get involved include emergency physicians for initial diagnosis, neurologists for ongoing neurological symptoms, neuropsychologists for cognitive testing and documentation and deficits, psychiatrists if there are mood or behavioral changes, and sometimes neuro-ophthalmologists if there are any vision issues. Physical therapists, occupational therapists, and speech therapists may also provide valuable documentation of functional limitations.
