Overview

Common risk factors in the development of brain abscess are immunodeficiency, chronic diseases, and congenital heart diseases.

Risk Factors

Common risk factors in the development of brain abscesses include:

• 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
• Decline in consciousness
  • Caused by seizures or status epilepticus
