Overview
Delusional Disorder
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.
Avascular Necrosis
Avascular necrosis, also called osteonecrosis, occurs when reduced blood supply causes bone tissue to die. It most often affects the hip but can involve other joints such as the knee, shoulder, or ankle. Early disease may cause no symptoms, while progressive damage can produce persistent pain, stiffness, reduced movement, and eventually collapse of the affected bone or joint surface. The condition may develop gradually and can be associated with injury, certain medicines, medical conditions, or other factors that impair blood flow to bone.

Delusional Disorder
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.
Avascular Necrosis
Diagnosis is based on symptoms, physical examination, medical history, and imaging of the affected bone. X-rays may appear normal in early disease, while magnetic resonance imaging can detect changes at an earlier stage. Additional imaging may help determine the extent of bone damage or joint collapse. Blood tests and other investigations may be used to identify an underlying condition or contributing cause, particularly when disease occurs at an unusual age or without an obvious risk factor.
Prevention
Delusional Disorder
There is no established method for reliably preventing delusional disorder. Early evaluation of persistent or unusual beliefs, particularly when they cause significant distress, conflict, or changes in behavior, can help identify possible mental health or medical causes and connect the person with appropriate professional care.
Avascular Necrosis
Some cases of avascular necrosis cannot be prevented, particularly when an underlying medical condition is responsible. Risk may be reduced by avoiding excessive alcohol consumption, using corticosteroids only as medically indicated, and discussing long-term corticosteroid exposure with a healthcare professional. Prompt assessment after significant joint or bone injury may be appropriate. People with medical disorders associated with osteonecrosis may benefit from appropriate management and monitoring for complications.
Risk Factors
Delusional Disorder
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.
Avascular Necrosis
Risk factors include prolonged or high-dose corticosteroid use, heavy alcohol consumption, previous fractures or joint trauma, and certain medical conditions affecting blood vessels or blood clotting. Associations have also been reported with disorders such as sickle cell disease, lupus, certain metabolic disorders, and some organ-transplant or cancer-related conditions. The risk varies according to the underlying cause, duration of exposure, and the location and extent of impaired blood supply.
