Dream-Reality confusion: differential psychiatric diagnosis in narcoleptic subjects

Resumen

Dream-reality confusion (DRC) is the consequence of hypnagogic content confusion with real events and memories. Narcoleptic subjects eventually have DRC and can be misdiagnosed as schizophrenic or with another disorder with delusional or hallucinatory symptoms. Although dream-related experiences and hallucinatory perception share neurophysiological pathways, they are phenomenologically distinct. The lack of phenomenological intentionality in Dreamrelated perceptions, the different cognitive pathways for delusion generation, and other differences between mental disorders psychopathology, and DRC-related phenomena are here discussed. The lived world and awake experience interpretation, and dream neurobiology in narcoleptic subjects related to DRC, might indicate some hints for the mind-brain gap issue that still exists in neurology and psychiatry.
