Schizophasia, also known colloquially as "word salad," is a mental disorder characterized by confused, disorganized usage of words with no apparent gramatical structure. Although the words may have a loose, thematic relation to the specific question asked or topic at hand, parsing a specific meaning from them is difficult or impossible.
Schizophasia is best known as a common symptom of schizophrenia, although it can also present as a symptom of a variety of other mental illnesses. It is also possible for schizophasia to be the sole symptom of mental illness, in what is sometimes termed "asymptomatic schizophrenia," although in some cases it is an early warning sign in patients who later develop more severe illness.
At present the US Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), does not classify schizophasia as a separate disorder, although it is mentioned as a symptom of schizophrenia.
