Summary
Persistent headache after ischemic stroke is common, affecting 10.1% of patients. Previous migraine and acute headache intensity are key risk factors for this debilitating post-stroke complication.
Area of Science:
- Neurology
- Stroke Medicine
- Headache Disorders
Background:
- Persistent headache post-ischemic stroke is recognized but under-researched.
- Limited data exists on its incidence, characteristics, and risk factors.
Purpose of the Study:
- To determine the incidence of persistent headache following ischemic stroke.
- To characterize the features of this headache type.
- To identify risk factors associated with its development.
Main Methods:
- Prospective cohort study of 119 ischemic stroke patients.
- Assessment included diffusion-weighted MRI, NIH Stroke Scale (NIHSS), and Headache Impact Test.
- Patients were interviewed 1-year post-stroke via telephone.
Main Results:
- 10.1% of patients developed persistent headache attributed to ischemic stroke.
- Migraine-like pattern was most frequent (58.3%), with significant impact in 41.7%.
- Previous migraine history (OR 7.1) and acute phase headache intensity (OR 1.75) were significant risk factors.
Conclusions:
- Persistent headache is a frequent complication after ischemic stroke.
- It significantly impacts patients' quality of life.
- A migraine-like phenotype is common, with prior migraine and acute pain intensity as predictors.

01:29Blood and Nerve Supply to the Bones
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
