Hallucinosis
Hallucinosis
Hallucinosis (/həˌluːsɪˈnoʊsɪs/) is a psychological condition characterized by the persistent presence of hallucinations without any impairment in consciousness or cognition.
Etymology
The term "hallucinosis" is derived from the Latin word "hallucinari," meaning "to wander in the mind," and the Greek suffix "-osis," indicating a state or condition.
Definition
Hallucinosis is a state in which a person experiences hallucinations but has a clear consciousness. These hallucinations can be visual, auditory, olfactory, gustatory, or tactile. Unlike psychosis, individuals with hallucinosis are aware that their hallucinations are not real.
Types
There are several types of hallucinosis, including:
- Alcoholic hallucinosis: This is a rare complication of chronic alcohol abuse, characterized by auditory hallucinations.
- Peduncular hallucinosis: This is a rare neurological disorder characterized by vivid, dream-like visual hallucinations.
- Charles Bonnet Syndrome: This is a condition associated with visual loss and complex visual hallucinations.
Related Terms

- Delirium: An acutely disturbed state of mind characterized by restlessness, illusions, and incoherence.
- Psychosis: A severe mental disorder in which thought and emotions are so impaired that contact is lost with external reality.
