Schizophrenia is a serious mental health disorder with a constellation of positive, negative, and cognitive symptoms. Negative symptoms can include characteristics such as affective flattening, avolition, and alogia. Positive symptoms can include delusions, hallucinations, and disorganized speech or behavior. Auditory hallucinations (AH) are a hallmark of schizophrenia. They are reported in as many as 50-75% of patients with this diagnosis. The hallucinations experienced by patients vary greatly and can severely impact an individual's ability to function on a daily basis. In approximately 25-30% of patients diagnosed with schizophrenia, medication is an ineffective mechanism for managing these symptoms. These hallucinations are known as medication refractory auditory hallucinations (MRAH). They are defined as "the persistence of daily hallucinations without remission despite antipsychotic medication at an adequate dosage for at least three months".
