From Brudzinski to Jamil: Unveiling Classical and Emerging Clinical Signs of Meningitis.

Meningitis can result from bacterial, viral, fungal, or noninfectious causes and requires early recognition to reduce both death and long-term complications. While laboratory testing and imaging confirm the diagnosis, bedside examination remains pivotal in guiding initial clinical decisions. This narrative review summarizes the main clinical signs of meningitis, both classical and more recently described, and discusses their diagnostic value. A structured literature search was conducted across major medical databases and sources, focusing on physical signs rather than laboratory or imaging approaches. Classic signs such as Kernig's and Brudzinski's are well recognized but limited by variable sensitivity. Other bedside maneuvers, including jolt accentuation and less commonly used signs, provide additional diagnostic context. Emerging signs, such as Jamil's sign, highlight the potential for improved detection of subtle meningeal irritation. Although no single sign can confirm or exclude meningitis with certainty, combining several findings with careful clinical judgment enhances diagnostic accuracy. In resource limited settings, bedside signs remain especially critical where access to imaging and laboratory confirmation may be delayed. Training clinicians in the correct interpretation and performance of these signs, and incorporating these into practice, can improve patient outcomes while strengthening early diagnosis. Future work should continue to validate emerging signs across diverse populations and encourage uniform examination protocols.
