In general; According to ICD-10 (F06.0), presence of either persistent or recurrent hallucinations due to an underlying organic cause is required for the diagnosis of organic hallucinosis. Additionally; It is important to rule out any major disturbance of consciousness, intelligence, memory, mood or thought.
Besides this; These hallucinations can occur in any sensory modality but are usually visual (most common) or auditory in nature.
These hallucinations can range from very simple also unformed, to very complex and well-organised. Lastly; Usually the patients realize that the hallucinations are not real but sometimes there may be a delusional elaboration of hallucinations. [1]
