Chronic Paranoid Schizophrenia: Definition, Symptoms, Diagnosis, Treatment

Chronic paranoid schizophrenia is a psychiatric disorder that is manifested by a hallucinatory delirium. Hallucination is a pathological sensation perceived in the absence of any stimulus.

This syndrome usually occurs in women at an advanced age and can occur in a patient who has an otherwise "normal" mental structure. The evolution of the disease alternates with periods of remission and moments of aggravation. In general, in the months preceding the illness, a landmark event occurs, such as professional difficulties, economic hardship, divorce, or bereavement.

It is important to distinguish chronic hallucinatory psychosis from other delusional disorders, such as paranoia and schizophrenia.


The symptoms of chronic paranoid schizophrenia are: delusions, contrary to facts; auditory hallucinations, where the patient hears voices; cenesthetic hallucinations, i.e. the perception of tactile sensations such as touching or fondling; rarely, visual hallucinations, or hallucinations regarding taste or smell; emotional disorders.


The diagnosis of chronic paranoid schizophrenia is made by a psychiatrist, after several interviews. No other additional examination is necessary for diagnosis, although some tests, such as a blood test or brain imaging can be performed to eliminate the possibility of organic disorders.


The treatment of chronic paranoid schizophrenia is based on antipsychotic medications, often neuroleptics. The treatment is not curative, but it treats the symptoms of the disease. On the other hand, psychotherapeutic care is needed. Social care is often prescribed and will protect the patient from a legal standpoint.
