During the first examination,2 patients were diagnosed as being in a vegetative state by 2 of us and 3 additional patients by 1 of us.One of us did not diagnose any patients as being in a vegetative state.A second evaluation of the same patients was performed 2 months later,after holding a consensus meeting to standardize the evaluation procedure.During the second evaluation,the vegetative state was diagnosed in 6 patients,but only by 1 of us.The diagnostic disagreement between the neurologists indicates that Alzheimer disease may only rarely progress to the persistent vegetative state. |
