Headache (Jan 2019)

INTRODUCTION Although headaches attributed to ischemic strokes and transient ischemic attack occur frequently, they are often overlooked and underdiagnosed as manifestations of cerebrovascular disease.

METHOD This is a narrative review.

RESULTS The prevalence of headache attributed to ischemic stroke varies between 7.4% and 34% of cases and of headache attributed to transient ischemic attack, from 26% to 36%. Headache attributed to ischemic stroke is more frequent in younger patients, in migraineurs, in those who have suffered a larger stroke, a posterior circulation infarction, or a cortical infarction, and is less frequent in lacunar infarctions. The most common pattern of headache attributed to ischemic stroke is a mild to moderate bilateral pain, not associated with nausea, vomiting, photophobia, or phonophobia. This headache usually has a concomitant onset with focal neurologic deficit and improves over time. The few studies that have assessed the value of headache for a prognosis of ischemic strokes have demonstrated conflicting results. There are no clinical trials on pain management or prophylactic treatment of persistent headache attributed to ischemic stroke.

CONCLUSION Headache attributed to ischemic stroke is frequent and usually has a tension-type headache pattern. Its frequency varies according to the stroke’s etiology. Further studies are required on pain management, prophylactic treatment, and characteristics of this headache.

“Before AE took over the anesthesia department was described by the surgeons as the worst in the history of our hospital. The prior management company was having a cancelled surgery per day. I am happy to report there has not been one since they have taken over the department. Additionally we have seen a 905 reduction if requested preop
lab tests. The anesthesia department is now the very best hospital department in our entire facility.”

“Even though they are physically located 1000 miles away Anesthesia Experts just does not provide great anesthesia coverage they personally engage surgeons to increase their business. Last year my surgical volume rose by 24% and we are currently 50% ahead of last year and all of that growth is organic.”

“Anesthesia Experts is more responsive than anyone I have dealt with. They are available by phone whenever needed and will be on site for any need or request and has been on site to address issues before we can make the request.”

“While problems are extremely rare when they do occur Anesthesia Experts quickly and professionally implements a solution. Our surgical volume has grown over 100 cases per month and now our GI docs want to perform all of their endoscopies in our hospital instead of their GI lab that they own!”
