MMN has influenced theories of language perception, together with studies of cognitive development and musical intelligence. Risto Näätänen has been most interested in the clinical scope: abnormalities of MMN have been associated with alcoholism, psychosis in schizophrenia, Alzheimer's disease, Parkinson's disease, and dyslexia. Facets of MMN have been associated with the prediction of waking in comatose individuals - as has been hailed as a breakthrough - yet MMN has remained a research tool and has not met criteria to determine clinical decisions about the continuation of life support.
