What we do

Department of Psychosomatic Medicine & Psychiatry

~ Compassionate, Multidisciplinary Mental Health Care for Mind and Body ~

Physical and mental health are deeply interconnected. Our department provides comprehensive psychiatric and psychosomatic care for a wide range of conditions—from mood and anxiety disorders to complex neurodevelopmental and organic conditions.

Guided by an experienced multidisciplinary team—including psychiatrists, specialized nurses, certified clinical psychologists, and psychiatric social workers—we operate a active Psychiatric Consultation-Liaison Team (CLT) across the general hospital. We are committed to supporting both our patients and their families through dedicated, empathetic care.

Key Clinical Focus & Departmental Strengths

Multidisciplinary Consultation-Liaison Team (CLT): Active collaboration across general hospital wards to diagnose and manage emotional stress, delirium, or psychological symptoms arising during physical medical treatments.

Strengthened Clinical Psychology & Counseling: Dedicated full-time clinical psychologists working closely with medical staff to deliver individual psychotherapy, psychological testing, and pediatric/adolescent mental health support.

Family-Centered Consultations: If a patient is unable or hesitant to visit in person due to illness or personal reasons, family members are warmly welcomed to consult with our team first.

Dedicated First-Time Appointment System: Initial visits are scheduled separately from follow-up appointments to allow ample time for thorough evaluation and history taking. (Urgent cases with severe or acute symptoms are handled with priority).

Pioneering Liaison Guidelines: Developed the Psychiatric Liaison Team Activity Guidelines (Draft) under a Ministry of Health, Labour and Welfare grant, setting standards for multi-professional psychiatric liaison care.
