Elderly patients are at increased risk for persistent complaints after mild traumatic brain injury (MTBI). This study aimed to investigate the role of post-concussive symptoms, mood, post-traumatic stress, and coping on functional outcome in elderly with MTBI. Information on mood, post-concussive symptoms, post-traumatic stress, and coping was collected 2 weeks post-injury. Six months post-injury functional outcome was assessed with the Glasgow Outcome Scale Extended. One hundred and sixty-two patients aged ≥ 60 years were included, 55% male, mean age = 71 (±6.2) years. The most frequent cause of injury was falls from standing height (75%). Two weeks post-injury anxiety, depression, and post-traumatic stress were present in 15%, 12%, and 38% of patients, respectively, with 73% reporting post-concussive symptoms. Avoidant coping was the most frequently used coping style. Six months post-injury, 44% showed incomplete recovery. Higher depression scores (OR = 0.87, p = 0.005) and number of post-concussive symptoms (OR = 0.91, p = 0.03) were associated with incomplete recovery. Half of the elderly showed incomplete recovery 6 months after MTBI, with early depression or post-concussive symptoms as important factors. Coping style was not related to outcome. These results underline the need for a different approach in elderly patients, focusing on other predicting factors and fall prevention strategies.
