The role of mood, post-traumatic stress, post-concussive symptoms and coping on outcome after MTBI in elderly patients

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.
