Delusional Disorder DSM-5

Delusional disorder, as defined in the DSM-5, is a psychiatric condition marked by the presence of one or more delusions lasting at least one month, without the prominent hallucinations, disorganized speech, or negative symptoms seen in other psychotic disorders. The individual's functioning is not markedly impaired outside the delusional context.

An example is the persecutory type, where an individual firmly believes they are being followed, conspired against, or targeted by others, despite no evidence to support these claims. This belief is persistent and impacts their thoughts, behaviors, and relationships.

The DSM-5 classifies mental disorders into broad categories such as neurodevelopmental disorders, depressive disorders, anxiety disorders, schizophrenia spectrum and other psychotic disorders, bipolar disorders, trauma- and stressor-related disorders, among others. Each category includes specific diagnostic criteria to ensure standardized assessment and treatment.
