Patients with brain injury and spasticity are candidates for intrathecal baclofen therapy (ITB) when maximal doses of oral antispastic drugs fail. Some authors have described an improvement in the level of consciousness in patients with brain injury and disorder of consciousness treated with ITB for spasticity. We present the case of a 43-year-old patient with brain injury, spasticity, and permanent vegetative state (PVS) who showed an improvement in the level of consciousness after ITB for spasticity. We performed an ITB infusion test, assessing the spasticity with the Modified Ashworth Scale (MAS) and level of consciousness with the Coma Recovery Scale-Revised (CRS-R) and observed an improvement in the spasticity and the level of consciousness. Consequently, the ITB pump was implanted and the patient recovered from PVS to minimal conscious state (MCS). We conclude that ITB is indicated in patients with brain injury and spasticity. We suggest the improvement in the level of consciousness as a possible additional benefit. There is a lack of evidence to recommend ITB in patients with altered level of consciousness.

Baclofen, a muscle relaxant prescribed for the alleviation of symptoms of spasticity acts primarily at the spinal level but with high doses, it penetrates the blood-brain barrier and can result in prominent central nervous depression. Baclofen toxicity has been associated with a variety of symptoms ranging from dizziness to deep coma. We report the clinical course, management, and outcome of a case of baclofen overdose who presented in deep coma with loss of brainstem reflexes and a burst suppression (BS) pattern on his electroencephalogram (EEG). In addition, we reviewed the presentation and outcomes of all reported cases of baclofen toxicity with a BS pattern on EEG to evaluate if those cases share a common clinical presentation and for the presence of signs and symptoms that would help the clinician to consider this diagnosis. There appears to be a common clinical picture associated with severe baclofen toxicity consisting of deep coma associated with loss of all brainstem reflexes including pupillary reactivity, frequent association with seizures/myoclonic jerks, and a BS pattern on EEG. The outcome is generally good, and serial EEGs are recommended to document a reversal of the abnormal electrographic features.
