What does a positive Brudzinski's sign indicate?

• A. Narcolepsy
• B. Meningitis
• C. Epilepsy
• D. Parkinson's Disease

Answer: (B)

A positive Brudzinski's sign is a clinical indicator used primarily in the assessment of meningitis. When a healthcare provider flexes a patient's neck and observes involuntary flexion of the hips and knees, this suggests irritation of the meninges, which are the protective membranes covering the brain and spinal cord. Meningitis, particularly bacterial meningitis, often presents with signs of meningeal irritation due to inflammation and increased sensitivity. Understanding the context of the other conditions is important as they do not typically present with this sign. Narcolepsy is characterized by excessive daytime sleepiness and sudden sleep attacks, while epilepsy involves episodes of seizures that arise from abnormal electrical activity in the brain. Parkinson's disease primarily affects motor control and has distinct symptoms such as tremors, rigidity, and bradykinesia, but does not involve signs indicative of meningeal irritation. Therefore, a positive Brudzinski's sign is specifically associated with the presence of meningitis.
