Delusional Disorder is characterized by one or more persistent delusions (fixed false beliefs) lasting at least one month, without other significant psychotic symptoms commonly seen in schizophrenia (e.g., prominent hallucinations, disorganized speech).
Key Points:
- Types of Delusions: Erotomanic, grandiose, jealous, persecutory, somatic, or mixed.
- Functioning: Apart from the direct impact of the delusion(s), individuals often appear relatively normal in behavior and functioning.
- Differential Diagnosis: Must rule out mood disorders with psychotic features and other psychoses (e.g., schizophrenia).
- Treatment: Psychotherapy (especially CBT), antipsychotic medications, and support in maintaining daily life activities.
