Can you tell me how is schizophrenia diagnosed?

Symptoms: First, schizophrenia (scz) has it's most common age of onset in the late teens or early 20s. A new diagnosis of scz for someone over the age of 40 is unusual. Then, the symptoms have to do with something called psychosis, i.e. Hallucinations and/or delusions. Finally, there are other conditions which may cause a person to become psychotic, including some physical causes. A psychiatrist can help.

Hallucinations: By definition, schizophrenia is about psychosis. Psychosis means the patient is getting external stimuli from the environment through one or more of his or her five senses, that does not objectively exist. In other words there are auditory,visual, olfactory, gustatory, and tactile hallucinations that can be experienced by the patient. Auditory hallucinations, however, are the most common.
