and Other Psychotic Disorders T he disorders in this section include Schizophrenia, Schizophreniform Disorder, Schizoaffective Disorder, Delusional Disorder, Brief Psychotic Disorder, Shared Psy- chotic Disorder, Psychotic Disorder Due to a General Medical Condition, Substance- Induced Psychotic Disorder, and Psychotic Disorder NotOtherwise Specified. These disorders have been grouped together' to facilitate the differential diagnosis of dis- orders that include psychotic symptoms as a prominent aspect of their presentation. Other disorders that may present with psychotic symptoms as associated·features are included elsewhere in the manual (e.g., Dementia of the Alzheimer's Type and Sub- stance-Induced Delirium in the "Delirium, Dementia, and Amnestic and Other Cog- nitive Disorders" section; Major Depressive Disorder, With Psychotic Features, in the "Mood Disorders" section). Despite the fact that these disorders are grouped together in this chapter, it should be understood that psychotic symptoms are not necessarily considered to be core or fundamental features of these disorders, nor do the disorders in this section necessarily have a common etiology. In fact, a number of studies sug- gest closer etiological associations between Schizophrenia and other diSorders that, by definition, do not present with psychotic symptoms (e.g., Schizotypal Personality Disorder) . .

Broader still is a definition that also includes other positive symptoms of Schizophrenia (Le., ~organized speech, grossly disorganized or cata- tonic behavior). Unlike these definitions I,>asedon symptoms, the definition used in earlier classifications (e.g., DSM-ll arid ICD-9fwas probably far too inclusive and fo- cused or the severity of functional impairment In that context, a mental disorder was termed "psychotic" if it resUlted in "impairment that grossJy interferes with the ca- pacity to meet ordinarydeinands of life." The term has also.previouslybeen defined as a ,"loss of ego boundaries" or a "gross impairmentinreality testing." .'. .In this manual, the term psychotic refers to the presence of certain symptoms. How- ever, the specific constellation of symptoms to which the term refers varies to some extent across the diagnostic categories. In Schizophrenia, Schizophreniform Disorder, Schizoaffective DisOrder, and Brief Psychotic Disorder, the term psychotic refers to de- lusions, any prominent hallucinations, disorganized speech, or disorganized or cata- tonic behavior.
