What does a positive Brudzinski's sign indicate?

• A. Arthritis
• B. Sciatica
• C. Meningitis
• D. Concussion

Answer: (C)

A positive Brudzinski's sign is a clinical indicator suggesting irritation of the meningeal layers surrounding the brain and spinal cord, which is commonly associated with meningitis. When a healthcare provider flexes an individual's neck and observes involuntary flexion of the knees and hips in response, it demonstrates that the protective mechanisms surrounding the central nervous system are reacting to irritation or inflammation. Meningitis can be caused by infections—whether viral, bacterial, or fungal—and as it progresses, inflammation of the meninges can occur, leading to symptoms such as headaches, fever, and neck stiffness. The manifestation of Brudzinski's sign reflects the body’s protective reflexes in response to such inflammation, making it a crucial sign in the evaluation of suspected meningitis cases. This sign is particularly significant during physical examinations, especially in emergency and acute care settings.
