Summary
Headache occurs in nearly one-fifth of acute ischemic stroke patients. It is significantly more frequent in lacunar strokes, particularly those with small, deep lesions.
Area of Science:
- Neurology
- Stroke Medicine
- Neuroscience
Context:
- Acute ischemic stroke is a leading cause of disability and mortality worldwide.
- Headache is a common symptom, but its specific association with stroke type and characteristics requires further elucidation.
- Understanding these associations can aid in diagnosis and patient management.
Purpose:
- To investigate the prevalence of headache in patients experiencing acute ischemic stroke.
- To determine the relationship between headache and stroke classification, etiology, and lesion localization.
- To analyze if headache frequency correlates with stroke characteristics.
Summary:
- Headache was present in 17.8% of 342 acute ischemic stroke patients.
- No correlation was found between headache and the size of ischemic lesions on CT scans.
- Headache occurred more frequently in patients with small, deep-seated lesions (43.1%) and large cortical-subcortical lesions (33.3%).
- Headache was statistically significantly more frequent in patients with partial anterior circulation infarct (POCI) according to the Oxfordshire Community Stroke Project (OCSP) classification.
Impact:
- Findings suggest headache may be a relevant clinical indicator for specific stroke subtypes, particularly POCI.
- This research can inform clinical assessment and differential diagnosis of headache in acute stroke patients.
- Further research into the pathophysiological mechanisms linking headache and stroke subtypes is warranted.
