topiramate and Post-Concussion-Syndrome

Topiramate is an effective treatment for alcohol use disorder (AUD) and has also been used in the care of mild traumatic brain injury (mTBI). This pilot study aimed to obtain a preliminary assessment of topiramate's efficacy in reducing alcohol use and post-concussive symptoms, and its potential negative impact on cognitive function in 32 Veterans with co-occurring AUD and mTBI.. This was a prospective 12-week, randomized, double-blind, placebo-controlled pilot study of flexible-dose topiramate or placebo. Primary outcome was reduction of drinking days per week within the topiramate arm. Secondary outcomes included between group comparisons of alcohol use and craving, post-concussive symptoms, and cognitive function.. Drinking days per week significantly decreased within both the topiramate and placebo arm. There were no significant treatment-by-week interactions on alcohol use/craving, or post-concussive symptoms in intent-to-treat analyses. In per-protocol analyses, topiramate significantly reduced number of drinks per week compared with placebo. Topiramate transiently impaired verbal fluency and working memory. Processing speed, cognitive inhibition, and mental flexibility significantly improved between weeks 1 and 12, regardless of treatment arm.. Significant improvement occurred in both the topiramate and placebo groups over 12 weeks of treatment in alcohol use and post-concussive symptoms. Among treatment completers there was greater reduction of alcohol use in the topiramate arm. Topiramate was also associated with negative but transient effects on cognitive function. Results suggest both a possible benefit for topiramate treatment in reducing alcohol use and some potential for negative cognitive effects in Veterans with AUD and mTBI.

Traumatic brain injury causes significant morbidity in youth, and headache is the most common postconcussive symptom. No established guidelines exist for pediatric post-traumatic headache management. We aimed to characterize common clinical practices of child neurologists. Of 95 practitioners who completed our survey, most evaluate <50 pediatric concussion patients per year, and 38.9% of practitioners consistently use International Classification of Headache Disorders criteria to diagnose post-traumatic headache. Most recommend nonsteroidal anti-inflammatory drugs as abortive therapy, though timing after injury and frequency of use varies, as does the time when providers begin prophylactic medications. Amitriptyline, topiramate, and vitamins/supplements are most commonly used for prophylaxis. Approach to rest and return to activities varies; one-third recommend rest for 1 to 3 days and then progressive return, consistent with current best practice. With no established guidelines for pediatric post-traumatic headache management, it is not surprising that practices vary considerably. Further studies are needed to define the best, evidence-based management for pediatric post-traumatic headache.
