Brainstem Auditory Evoked Potentials in Minor Head Trauma
|
|
|
|
|
Abstract
|
|
|
The present study was undertaken to explore the value of brainstem auditory evoked potentials(BAEPs) in the diagnosis of minor head trauma. There is the suggestion that diencephalon and mesencephalon fiber disruption and abnormal BAEPs might be
occurred
in minor head trauma. Most of the studies on BAEPs in head trauma have been performed in those severely affected and only a few studies have been reported in minor head trauma patients.
BAEPs were recorded from 20minor head trauma patients and 60 normal control subjects at a repetition stimulation rate of 10 click/sec. Two out of 20 patients showed statistically significant interpeak(III-V, and I-V) latency prolongations and
there
is a
significant difference between control group and minor head trauma group in absolute V wave latency and interpeak(III-V, and I-V) latency.
These findings suggest that some minor head-injured patients have the disturbance of brainstem function and BAEPs is thought to be of use in detecting the brainstem dysfunction following minor head trauma.
