Hydrocephalus Treatment on Persistent Disorder of Consciousness

After acute brain injury or haemorrhagic stroke, hydrocephalus might participate to consciousness disorder. We plan to explore whether ventriculoperitoneal shunt insertion improves consciousness in patients with vegetative or minimally conscious state and hydrocephalus. Patients with acute brain injury, persistent consciousness disorder and hydrocephalus will be shunted with a detailed follow-up at 3 months combining: clinical evaluation, FluoroDésoxyGlucose positron emission tomography imaging, high density electroencephalogram, electrocardiogram Holter and sympathetic activity by microneurography.
