One thing to be on the look out for in your patients is a severe, ‘different’ headache. Commonly referred to as a sentinel headache, this can be a warning sign of a stroke in progress!
 
Sentinel headache is characterized by a sudden, intense, persistent headache, with features different from any usual previous headache. Sentinel headache occur in approximately 15-60% of spontaneous subarachnoid hemorrhage patients, preceding the vascular event by days or even weeks. Put simply, a sentinel headache warns against an impending disease.
 
Currently, there is a paucity of literature examining sentinel headache in ischemic stroke patients. The aim of this study was to compare patients with and without sentinel headache in order to evaluate triggers, determine potential risk factors and provide clinical recommendations in order to assist in identifying patients with sentinel headache. The focus of the study is on headaches occurring within 7 days of an ischemic stroke. This is a very relevant topic for practicing chiropractors...LOG IN OR SUBSCRIBE TO ACCESS THIS REVIEW
