Electrophysiologic Evaluation of Diffuse Axonal Injury after Traumatic Brain Injury, Encephalitis
Author(s): Yuko UrakamiYuko Urakami
Background: Electroencephalography may provide useful information about consciousness and cognitive processing in patients who have traumatic brain injury. Sleep disturbance after traumatic brain injury may impair cognitive function and affect rehabilitation.
Methods: In 15 patients who had chronic diffuse axonal injury after traumatic brain injury, electroencephalography and neuropsychologic tests were performed. In 8 patients who had subacute and chronic diffuse axonal injury and 7 healthy control subjects, electroencephalography, magnetoencephalography, and neuropsychologic tests were performed to evaluate sleep spindles and cognitive function.
Results: In the chronic stage of diffuse axonal injury, the mean peak frequency of alpha activity was significantly slower in patients who had abnormal than normal electroencephalography. The mean peak frequency of fast spindle.. View More»
