Hebephrenic Schizophrenia Diagnostic Criteria
The formal diagnosis of hebephrenic schizophrenia rests on these symptoms, which can be evaluated bypsychiatrists and other mental health professionals.
ICD-10 Criteria for Hebephrenic Schizophrenia
The following information is reproduced verbatim from the ICD10 Classification of Mentaland Behavioural Disorders, World Health Organization, Geneva, 1992. (Since the WHOupdates the overall ICD on a regular basis, individual classifications within it may or maynot change from year to year; therefore, you should always check directly with the WHO tobe sure of obtaining the latest revision for any particular individual classification.)
F20.1 Hebephrenic Schizophrenia
A form of schizophrenia in which affective changes are prominent, delusions and hallucinations fleeting and fragmentary, behaviourirresponsible and unpredictable, and mannerisms common. The mood is shallow and inappropirate and often accompanied by giggling orselfsatisfied, selfabsorbed smiling, or by a lofty manner, grimaces, mannerisms, pranks, hypochondriacal complaints, and reiteratedphrases. Thought is disorganized and speech rambling and incoherent. There is a tendency to remain solitary, and behaviour seems emptyof purpose and feeling. This form of schizphrenia usually starts between the ages of 15 and 25 years and tends to have a poor prognosisbecause of the rapid development of “negative” symptoms, particularly flattening of affect and loss of volition.
In addition, disturbances of affect and volition, and thought disorder are usually prominent. Hallucinations and delusions may be presentbut are not usually prominent. Drive and determination are lost and goals abandoned, so that the patient’s behaviour becomescharacteristically aimless and empty of purpose. A superficial and manneristic preoccupation with religion, philosophy, and other abstractthemes may add to the listener’s difficulty in following the train of thought.
Diagnostic Guidelines
The general criteria for a diagnosis of schizophrenia (see introduction to F20 above) must be satisified. Hebephrenia should normally bediagnosed for the first time only in adolescents or young adults. The premorbid personality is characteristically, but not necessarily, rathershy and solitary. For a confident diagnosis of hebephrenia, a period of 2 or 3 months of continuous observation is usually necessary, inorder to ensure that the characteristic behaviours described above are sustained.
