N1 - Funding Information:
This research was supported through a memorandum of understanding among the American Academy of Neurology, the American Congress of Rehabilitation Medicine, and the National Institute on Disability and Rehabilitation Research (NIDRR). In 2014, NIDRR was moved from the US Department of Education to the Administration for Community Living of the US Department of Health and Human Services, and was renamed the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR). This article does not reflect the official policy or opinions of NIDILRR or HHS and does not constitute an endorsement by NIDILRR, HHS, or other components of the federal government.
Funding Information:
This practice guideline was funded by the American Academy of Neurology (AAN), the American Congress of Rehabilitation Medicine, and the National Institute on Disability, Independent Living, and Rehabilitation Research. Authors who serve or served as AAN subcommittee members (E.J.A., S.A., R.B., G.S.G.) or as methodologists (M.J.A., G.S.G.), or who were AAN staff members (T.S.D.G.), were reimbursed by the AAN for expenses related to travel to subcommittee meetings where drafts of manuscripts were reviewed.

N2 - Objective: To update the 1995 American Academy of Neurology (AAN) practice parameter on persistent vegetative state and the 2002 case definition for the minimally conscious state (MCS) by reviewing the literature on the diagnosis, natural history, prognosis, and treatment of disorders of consciousness lasting at least 28 days. Methods: Articles were classified per the AAN evidence-based classification system. Evidence synthesis occurred through a modified Grading of Recommendations Assessment, Development and Evaluation process. Recommendations were based on evidence, related evidence, care principles, and inferences according to the AAN 2011 process manual, as amended. Results: No diagnostic assessment procedure had moderate or strong evidence for use. It is possible that a positive EMG response to command, EEG reactivity to sensory stimuli, laser-evoked potentials, and the Perturbational Complexity Index can distinguish MCS from vegetative state/unresponsive wakefulness syndrome (VS/UWS). The natural history of recovery from prolonged VS/UWS is better in traumatic than nontraumatic cases. MCS is generally associated with a better prognosis than VS (conclusions of low to moderate confidence in adult populations), and traumatic injury is generally associated with a better prognosis than nontraumatic injury (conclusions of low to moderate confidence in adult and pediatric populations). Findings concerning other prognostic features are stratified by etiology of injury (traumatic vs nontraumatic) and diagnosis (VS/UWS vs MCS) with low to moderate degrees of confidence. Therapeutic evidence is sparse. Amantadine probably hastens functional recovery in patients with MCS or VS/UWS secondary to severe traumatic brain injury over 4 weeks of treatment. Recommendations are presented separately.
