Meningismus is a commonly overlooked finding in tension-type headache in children and adolescents.

At present, both migraine and tension-type headaches in children are believed to be chronic primary headaches. Meningeal signs in both cases are ignored or not examined, and the neurologic status is considered normal. This is the first study that focuses on meningeal signs in children with chronic headaches. The study population comprised 1738 patients aged 5 to 17 years who were examined in an outpatient neurologic clinic over a 6-year period. Particular attention was paid to examination of meningeal signs, including nuchal rigidity, Kernig's sign, Brudzinski's three signs (upper, middle, and lower), the "tripod" sign, and Guillain's and facial signs; the presence of these signs was regarded as meningismus syndrome. Some meningeal signs were found in 12% of 1007 children suffering from migraine, whereas 97% of 731 children with tension-type headaches had the whole set of meningeal signs. This suggested that meningismus is the major clinical syndrome in chronic tension-type headaches in children and adolescents. Chronic mild sterile (possibly autoimmune) inflammation of meninges (dura mater) can be caused by a preceding infection, as well as minor trauma of the head and/or back. Prolonged rest in a recumbent position usually resulted in relief or complete disappearance of both headache and meningeal signs. Monitoring of the meningeal signs is helpful for evaluation of the patient's condition in the course of treatment.
