Long-term physical, cognitive, and behavioral impairments are the factors that most commonly limit a patient's re-integration into the community and his/her return to employment.

In a study by Kraus and colleagues of 235 patients, the symptoms most commonly reported 6 months after mild TBI were fatigue (43%), weakness (43%), memory deficits (40%), headache (36%), and dizziness (34%). [59] Other investigators found similar complaints after mild TBI. [60, 61] The symptoms have collectively been referred to as postconcussion syndrome. [62] Kraus and co-authors found that approximately 83% of patients with mild TBI reported 1 or more physical complaints at the end of their 6-month follow-up period. [59, 63]
