Explanation

Someone with a mental illness that's caused them to lose touch with reality and to withdraw from society may end up being diagnosed with schizophrenia, a serious disorder that can usually be treated with medication. A Swiss psychiatrist first came up with the term Schizophrenie, or "a splitting of the mind," to refer to the mental illness in 1910. A person with schizophrenia may feel and behave as if his mind has split off from reality, as he perceives things in a distorted way, and often speaks and acts in ways that appear bizarre. Sometimes schizophrenia is used to mean "inconsistent or contradictory."
