Areas of activities and approaches of treatment in consultation-liaison psychiatry Consultation-liaison psychiatry represents one of the newer fields of psychiatry with increasing importance amidst the interface of medicine and psychiatry. The understanding of the substantial degree of incidence and prevalence of psychiatric illness in medical disease has made this sub-specialty essential to the modern general hospital.
