Disability and quality of life 20 years after traumatic brain injury.

Functional limitations persist even decades after moderate and severe TBI, with poorer prognosis for females and persons who were depressed at the 10-year follow-up. Development and evaluation of targeted long-term follow-up programs and access to rehabilitation services for these groups should be highlighted. Improved community integration despite stable functional limitations draws attention to long-term adaptation to adversity and illness.
