Risk Factors

The following raise your risk of a brain abscess:

• A weakened immune system (such as in AIDS patients)
• Chronic disease, such as cancer or Osler-Weber-Rendu syndrome
• Drugs that suppress the immune system (corticosteroids or chemotherapy)
• Right-to-left heart shunts, usually the result of congenital heart disease
