The term "Mental Cases" is not widely recognized as a formal or established concept in clinical psychology, psychiatry, or medical taxonomy. It does not correspond to a standard diagnostic category or classification within authoritative medical references such as the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) or the International Classification of Diseases (ICD-11).
Accurate information is not confirmed regarding "Mental Cases" as a defined term in scientific, medical, or academic literature. It may be interpreted as a non-technical, colloquial, or outdated phrase potentially used to refer to individuals experiencing mental health disorders, but such usage is imprecise and not recommended in professional or clinical contexts.
Possible contextual use of the phrase could include literary, historical, or rhetorical references, such as in poetry or early 20th-century discourse on shell shock or war-related psychological trauma. For example, the poet Wilfred Owen used the phrase "Mental Cases" as the title of a poem addressing the psychological suffering of soldiers during World War I. In this context, it serves a literary rather than clinical function.
Due to the lack of standardized definition or recognition in contemporary medical or psychological frameworks, "Mental Cases" should not be used in place of specific, clinically appropriate terminology.
