Insights
Transient ischemic attack (TIA) patients with cerebral infarction on CT scans are older and have worse outcomes. Differentiating these TIAs is crucial due to distinct causes and prognoses.
Area of Science:
- Neurology
- Radiology
Background:
- Transient ischemic attack (TIA) is a critical warning sign for stroke.
- Cerebral infarction detection on computed tomography (CT) scans impacts TIA prognosis.
Purpose of the Study:
- To identify differences between TIAs with and without cerebral infarction on CT scans.
- To determine if these differences warrant distinct clinical management.
Main Methods:
- Prospective study of 175 consecutive patients presenting with TIA.
- CT scans were used to diagnose cerebral infarction.
- Patient demographics, neurological deficits, medical history, and outcomes were analyzed.
Main Results:
- 21% (36/175) of TIA patients showed cerebral infarction on CT.
- Patients with infarction were older, had longer deficits, and more frequent neurological history.
- Higher rates of vertebro-basilar TIAs, headaches, cardiac arrhythmia, and 2-year mortality were observed in the infarction group.
Conclusions:
- TIA patients with CT-detected cerebral infarction represent a distinct subgroup.
- Etiological factors and prognosis differ significantly, necessitating separate consideration.
- Clinical differentiation of TIAs with cerebral infarction is essential for appropriate patient care.
Abstract:
In a prospective study, thirty six out of 175 consecutive patients (21%) with transient ischemic attack (TIA), had cerebral infarction on CT-scan. This group of patients differed from the group without cerebral infarction by a higher age, a longer duration of neurological deficit, a greater frequency of neurological history, vertebro-basilar TIAs, cephalagia and, cardiac arrhythmia, and by a higher 2-year mortality rate. Due to their difference in etiological factors and prognosis, TIAs with cerebral infarction on CT-scan should be differentiated from those without cerebral infarction.
