Headache occurred in 29% of transient ischemic attack patients. This symptom was more frequent in nonsmokers and those with lacunar events, but poorly explained by clinical features.

Area of Science:

  • Neurology
  • Stroke Medicine

Background:

  • Headache is a common symptom, but its association with transient ischemic attacks (TIAs) requires further investigation.
  • Understanding TIA clinical presentations aids in diagnosis and risk stratification.

Purpose of the Study:

  • To investigate the incidence and clinical correlates of headache in patients experiencing transient ischemic attacks.
  • To determine if headache characteristics are associated with specific TIA etiological factors or imaging findings.

Main Methods:

  • Retrospective analysis of 205 consecutive patients with transient ischemic attacks from a hospital stroke database.
  • Data collection included headache occurrence within 72 hours of TIA onset, patient demographics (smoking status), clinical presentation, and neuroimaging results (computerized tomography).

Main Results:

  • Headache was reported by 29% of patients.
  • Headache was significantly more common in nonsmokers (OR=2.8) and in TIAs within the vertebrobasilar (33%) versus carotid (24%) distribution.
  • Diffuse headache was more frequent in lacunar events compared to cortical attacks (OR=3.0). Headache was less frequent when CT scans showed an infarct (OR=0.2).

Conclusions:

  • Headache in TIA patients is not strongly correlated with most clinical features or vascular territories.
  • Smoking status and specific TIA subtypes (lacunar, vertebrobasilar) may be associated with headache.
  • The presence of an infarct on CT scan was associated with a lower likelihood of headache.
