Mental and behavioral disorders
(F00-F99)

The schizophrenic disorders are generally characterized by fundamental and characteristic disorders of thinking and perception, as well as inadequate or shallow affects. Clarity of consciousness and intellectual abilities are usually not impaired, although certain cognitive deficits can develop over time. The most important psychopathological phenomena are the sounding of thoughts, the introduction or withdrawal of thoughts, the spread of thoughts, delusion, delusions of control, delusions of influence or the feeling of being made, voices that comment on or speak about the patient in the third person, thought disorders and negative symptoms.

The course of schizophrenic disorders can either be continuous episodic with increasing or stable deficits, or one or more episodes with complete or incomplete remission can occur.

The diagnosis of schizophrenia should not be made in marked depressive or manic symptoms, unless schizophrenic symptoms preceded the mood disorder. Schizophrenia cannot be diagnosed if there is a definite brain disease, during intoxication or during a withdrawal syndrome. Similar disorders in epilepsy or other brain disorders should be coded under F06.2, psychotic disorders caused by psychotropic substances under F10-F19, fourth digit .5.
