The American Academy of Neurology (AAN) has received many inquiries from the press regarding the definition of persistent vegetative state in light of the Terri Schiavo case. In 1995 the AAN published a practice parameter about the assessment and management of patients in the persistent vegetative state. This parameter includes definition and diagnosis information. It is publicly accessible at www.aan.com. The direct link opens as a .pdf file: http://www.aan.com/professionals/practice/pdfs/pdf_1995_thru_1998/1995.45.1015.pdf
The AAN Ethics, Law, and Humanities Committee (formerly known as Ethics and Humanities Subcommittee) published an approved position paper in 1989 about certain aspects of the care and management of patients in the persistent vegetative state. It can be directly opened as a .pdf file: http://www.aan.com/about/ethics/109556.pdf
