HIGHLIGHTSNeurorehabilitation is effective after experimental TBI.Digging- and operant-based attentional tasks are sensitive measures of executive function after TBI.CB1 receptors implicated in neuroendocrine stress and plasticity.Antipsychotic and antiepileptic drugs impair functional recovery.The aim of this review is to discuss the research presented in a symposium entitled “Current progress in characterizing therapeutic strategies and challenges in experimental CNS injury” which was presented at the 2016 International Behavioral Neuroscience Society annual meeting. Herein we discuss diffuse and focal traumatic brain injury (TBI) and ensuing chronic behavioral deficits as well as potential rehabilitative approaches. We also discuss the effects of stress on executive function after TBI as well as the response of the endocrine system and regulatory feedback mechanisms. The role of the endocannabinoids after CNS injury is also discussed. Finally, we conclude with a discussion of antipsychotic and antiepileptic drugs, which are provided to control TBI-induced agitation and seizures, respectively. The review consists predominantly of published data.
