Neuropsychiatry Department

What is the Neuropsychiatry Department?

We provide treatments for various psychiatric disorders caused by central nerve dysfunction or by psychosocial stressors. Specialized Psychiatrists perform diagnoses, examinations, rational pharmacological treatments, and psychotherapy so that patients and their family can improve quality of life. We also aim to contribute to clarify causes and pathology of those psychiatric disorders.

Treatment system

With nuclei of physicians specializing in respective disease fields, the Department of Neuropsychiatry administers highly advanced medical treatments, education, and research. The outpatient clinic service deals with medical care and specialized examinations of depression, bipolar disorders, schizophrenia, dementia, liaison (psychological change related to the physical disorders and their treatment) plus stress disorders, GID, and puberty-related disorder. For inpatients, both closed and open wards have 28 beds in all. Since 2013, individual rooms have been available for every impatient. Treatments and specialized tests are provided through conferences of several specialists.

Treatment policy

Several specialists have conferences. Their team provides front-line and optimum medical care. As a general hospital’s neuropsychiatry department, we can provide mental and physical treatments and specialized examinations at a time by collaborating with each department, and also respond to the hospitalization of mentally impaired patients suffering from physical diseases.

Description of medical care

The department performs diagnoses and administers treatments of mental diseases. In inpatient service, we deal mainly with treatment and tests for depression, schizophrenia, anxiety, and stress-related disorders. Additionally, we perform diagnoses and treatment for precritical and mild dementia and schizophrenia and its high-risk group. Furthermore, we strive to respond to the hospitalization of as many mentally impaired patients suffering from physical diseases as possible.
In outpatient clinic services, we specifically examine depression, bipolar disorder, schizophrenia, and anxiety and stress disorders. Additionally, we offer specialized outpatient service for memory loss (dementia tests), mental risk/schizophrenia, puberty consultation, liaison, and gender identity disorder.

For outpatients

The Neuropsychiatry Department of Okayama University Hospital is an institute tasked with performing highly advanced medical treatment, education, and research. In outpatient clinic services, we try to provide the best treatment for every patient with a diagnosis that specialists spend sufficient time to make, detailed examinations, and respect to a patient’s sentiment. Both first-visiting and re-visiting patients must make an appointment in advance.

(1) For patients visiting the department for the first time

For you to have your personal physician, we recommend that you first visit a clinic or a hospital and be examined there by the doctors specializing in psychiatry or psychosomatic medicine. If they advise you to receive further examinations or hospital treatment at a university hospital, then please have them refer you to our department.

(2) About continuation therapy

Now that your treatment policy has been decided according to your condition and we have a vision for your treatment, we will refer you to another medical institution for continuation therapy. In the future, when you must have further examinations and hospital treatment, we will respond to them smoothly in cooperation with it. Please make sure to make an appointment in advance if you visit our department again.
When you are an outpatient and must have our emergent examination, please call the outpatient clinic service first.
Thank you for understanding our mission to aim for highly advanced medical treatment of a university hospital and your cooperation.
