Delusional Disorder
Urgent
Delusional disorder is a mental health condition characterized by one or more firmly held false beliefs that persist for at least one month. The beliefs may concern subjects such as persecution, jealousy, relationships, or physical health. Unlike some other psychotic disorders, prominent hallucinations, disorganized speech, and other major psychotic symptoms are not typical features of the disorder.

When to Seek Medical Attention
Delusional disorder requires professional mental-health assessment when persistent false beliefs interfere with functioning or relationships. Seek prompt care when beliefs become increasingly distressing, behavior changes significantly, or the person becomes increasingly detached from reality. Emergency assistance is needed for dangerous behavior, severe confusion, hallucinations with loss of behavioral control, suicidal or violent thoughts, or inability to remain safe.

Overview
Delusional disorder is a mental health condition characterized by one or more firmly held false beliefs that persist for at least one month.

Symptoms 2
Confusion
Delusions
Causes 1
The exact cause of delusional disorder is not fully understood. Psychotic disorders can arise from a complex combination of biological, genetic, psychological, and environmental factors. Delusions can also occur as a result of certain medical conditions, medications, or substance use, so these possibilities need to be considered during evaluation.
Stress
Risk Factors
The factors associated with delusional disorder are not completely understood. It generally develops in adulthood and may occur more often in middle-aged or older adults. A history of certain personality traits or other psychiatric or medical conditions may be relevant, but no single factor reliably predicts who will develop the disorder.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis requires a comprehensive psychiatric assessment and review of the person's history and symptoms. A healthcare professional evaluates the nature and duration of the beliefs and assesses whether other psychotic disorders, mood disorders, substance use, neurological conditions, or other medical causes could explain the symptoms.

Key Prevention Tips
