Creativity, language, and psychotic disorders may share a common neurological and evolutionary background. These processes are uniquely human and may converge in poetic expression that illuminates the inner world of patients suffering from schizophrenia. Two types of poetry that may be written by patients with schizophrenia are identified as morbid and insight poetry. Clinicians are urged to pay attention to the writings of their patients and encourage them to document the experiences of their illness. Writing may help patients gain an in-depth insight into their own inner world and the nature of their illness. Poetry may also help clinicians understand the peculiar individual psychodynamics of their patients' illness.
