A Comparison of Quantitative Electroencephalography, Computed Tomography, and Behavioral Evaluations to Localize Impairment in Patients with Stroke and Transient Ischemic Attacks

Brain computed tomography and a structured behavioral assessment provided a better correlation than did quantitative electroencephalography to the presence of mild stroke or transient ischemic attacks in 21 patients. When electroencephalography did not correlate well, it tended to localize too laterally or miss deep lesions. Computed tomography did not identify 2 lesions when done early after disease onset. No test was uniformly more sensitive or accurate than others. They may complement each other.
