抄録

Psychiatry is one field of medicine and treat of mental illness. However it is very unclear to distinguish mental illness from normal mental state. DSM-V(which is released by the American Psychiatric association) classifies mental illness mainly on the basis of not cause but statistical evidence. Even now there is no consistent consequence about the cause of mental illness. Many researchers have argued for a long time about endogen, exogen and psychogenic cause.
 In this paper, we will discuss about the true nature of mental illness and what is the difference between mind spirit. On this occasion, we will consider what a diagnosis for psychiatry is.
