Final answer:
Psychotic disorders like schizophrenia can result in false sensory perceptions known as hallucinations, which can include hearing non-existent voices. Delusions are different and refer to false beliefs. Treatment typically involves antipsychotic medication that alters dopamine neurotransmission.
Step-by-step explanation:
Psychotic disorders, such as schizophrenia, often involve symptoms where individuals have difficulty distinguishing between reality and imagination. One common symptom of these disorders is the perception of nonexistent sensory stimulation. Hallucinations refer to these false perceptions, such as hearing voices that aren't there. These are distinct from delusions, which are firmly held false beliefs not based on sensory experiences. Schizophrenia also includes 'negative' symptoms, like a lack of emotion and pleasure, which impacts a patient's quality of life significantly. The treatment typically involves antipsychotic medication, which modifies dopamine neurotransmission to help manage symptoms.
