Asaad's definition of hallucinations
- Asaad's definition of hallucinations
In 1990 the American psychiatrist Ghazi Asaad defined hallucinations as follows: "Hallucinations are generally defined as perceptions that occur in the absence of corresponding external stimuli. [...] True hallucinations are experienced and accepted by the patient as real perceptions. It is obvious that reality testing must be impaired in order for this symptom to appear."
