###Human: I am facing a problem of delusion. Is there any other solution for it? ###Assistant: Hi. Delusion is a false belief, which is very firm and unshakeable. It is a symptom of psychosis, which is found in schizophrenia, bipolar disorder, depression, mania, etc. It is due to increased dopamine chemical in the brain. Other causes are genetic, sociocultural and psychological. If you had shown a complete response on Soltus 100 mg in the past, then you can again start Soltus 100 mg now. Soltus (Amisulpride) is a antipsychotic medication, whose dose can be increased up to 400 mg. If you have continuous illness for the last 12 years, then you have to take medicine for a lifetime because chances of recurrence of these illnesses are very high. What is your height, your other symptoms, current sleep, appetite, your work?
