This literature review concludes that the use of benzodiazepenes (like Xanax and Valium) and similar drugs can impair cognitive function when used to treat sleep problems after TBI. The authors highlight some alternate treatments such as trazodone and melatonin agonists; however, they suggest further research is needed on their use for persons with TBI.
