TY - CHAP M1 - Book, Section TI - Confusional States A1 - Simon, Roger P. A1 - Aminoff, Michael J. A1 - Greenberg, David A. Y1 - 2017 N1 - T2 - Clinical Neurology, 10e AB - A confusional state, sometimes referred to as encephalopathy or delirium, is a state in which the level of consciousness is depressed, but to a lesser extent than in coma (unarousable unresponsiveness; see Chapter 3, Coma). In confusional states, responses to stimulation are at least semi-purposeful, whereas in coma, patients fail to respond to even painful stimulation or do so only in reflex fashion. Thus, the difference between a confusional state and coma is largely one of degree, and the causes overlap extensively.
