Disorganized schizophrenia

German psychiatrist Ewald Hecker first proposed the condition in the 1870s under the term hebephrenia, from Greek ἥβη (hḗbē) for adolescence, and -phrenia for mental disorder. The name referred to the ostensibly more prominent appearance of the disorder in teenagers and young adults. == Symptoms ==

In DSM-IV, the subtype was characterised by disorganized speech, behaviour, and flat or inappropriate affect, and diagnosed based on symptoms only. Disorganized speech, e.g., word salads, reflects an individual's underlying thought disorder; where an individual with disorganized behaviour may struggle to carry out normal daily activities. Inappropriate affect display is the outward presentation of one's emotions that, given the circumstances under which it is performed, is perceived by social norms to be awkward, offensive or otherwise unacceptable. The subtype was considered to be one in which these features were more prominent than in other types of schizophrenia, and affected individuals may carry more stigmatization. ==See also==
