There are some other factors that can cause auditory hallucination that are non psychotic in nature. Research has shown that auditory hallucination is caused by disturbance in the nerve cells and is closely related to use of dopamine as a neurotransmitter.Īuditory Hallucinations and Non Psychotic Causes Schizophrenic patients who frequently have these hallucinations are unable to recognize that the “voices” they hear are not real and are a product of their mind. Therefore auditory hallucination is quite significant in diagnosing these conditions. Most people who are schizophrenic or suffer from severe bipolar depression also show symptoms of auditory hallucination. Although it can be caused by neurological disorders like epilepsy or other non psychotic causes like extreme stress, auditory hallucinations are most often seen in patients with schizophrenia. In simple terms auditory hallucination is the perception of sound without any external auditory stimulus that seems very real to the individual hearing it. Auditory Hallucinations and Schizophrenia It is important to note that auditory hallucination is different from auditory illusions where the person misinterprets an auditory signal or stimulus. The voices are mostly negative in nature, and they usually curse, berate or humiliate the subject. Some people who hear such voices has reported that they hear multiple voices either talking to them, or about them or conversing with each other. The voices are clear and are either commanding or negative in nature. In auditory hallucination, people hear voices inside their head or have the perception that someone is talking to them, when there is no auditory stimulus. Hearing “sound” or “music” inside the head is not considered as auditory hallucination. This happens very rarely and this cannot be said to be auditory hallucination. Most people, at least once, “hear” or perceive some kind of sound or music without any external stimulus at some point in their life. Characteristics of Auditory Hallucinations
Auditory hallucination has also been seen to be closely associated with neurological disorder like epilepsy. The relationship between auditory hallucination and non psychotic causes are being studied, but till date research has been inconclusive. However, such hallucinations can also be caused due to post traumatic stress disorder (PTSD), drug abuse and sleep deprivation. Auditory hallucination is usually (not always) a symptom of mental illness or psychotic disorders such as schizophrenia or bipolar disorder. It is a form of hallucination that makes a person perceive sound without the aid of external auditory stimulus. But there is a more common form of hallucination, that is not visual in nature. Whenever we hear the word hallucination, we think of visual hallucination where a person “sees” something that does not exist.
