Summary

Ataxic hemiparesis, often considered a lacunar syndrome, frequently results from infarcts in various brain locations, not exclusively small deep ones. Diagnosis of lacunar infarction is confirmed in only about half of these stroke cases.

Area of Science:

  • Neurology
  • Stroke Medicine
  • Neuroimaging

Background:

  • Ataxic hemiparesis is typically classified as a lacunar syndrome.
  • Lacunar strokes are often associated with small deep infarcts and hypertensive small artery disease.

Purpose of the Study:

  • To investigate the neuroimaging findings and etiological causes of ataxic hemiparesis.
  • To determine the frequency of lacunar infarction in patients presenting with ataxic hemiparesis.

Main Methods:

  • Prospective analysis of 100 first-stroke patients with ataxic hemiparesis from stroke registries.
  • Brain CT or MRI imaging to identify lesion location and type (hemorrhage, infarct, leukoaraiosis).
  • Clinical assessment for associated signs and etiological investigation for stroke causes.

Main Results:

  • Infarcts were found in 72% of patients; primary hemorrhage in 5%.
  • Common lesion sites included internal capsule (39%), pons (19%), and thalamus (13%).
  • Lacunar infarct diagnosis was confirmed in only slightly over half of the cases, with varied lesion locations.

Conclusions:

  • Ataxic hemiparesis is not exclusively linked to lacunar infarction and can arise from lesions in diverse brain areas.
  • The clinical presentation of ataxic hemiparesis shows limited variation across different lesion locations.
  • Hypertensive small artery disease remains a leading cause, but embolic sources are also identified.
