Brainstem Auditory Evoked Potentials
Brainstem auditory evoked potentials (BAEPs) are electrical field potentials generated by stimulation of the auditory pathways. With repetitive auditory stimulation, reproducible electrical potentials can be elicited and recorded from scalp electrodes. These waves are generated by specific brain regions and occur at predictable intervals. Clinically, this neurophysiological property is useful t...
متن کاملIntraoperative monitoring of brain-stem auditory evoked potentials.
Brain-stem auditory evoked potentials (BAEP) were monitored during 545 neurosurgical operations in the cerebellopontine angle. The BAEP were irreversibly obliterated in five patients who required deliberate section of the auditory nerve. Technical difficulties interfered with monitoring in three cases, and three patients had deafness and absent BAEP preoperatively. Reversible alterations in BAE...
متن کامل[Brainstem auditory evoked potentials in diabetes mellitus].
It is well-known that diabetic patients develop peripheral and autonomic neuropathy, and recent review has also suggested the occurrence of central pathway abnormality in diabetics. In this article, we conducted the BAEP study on 61 cases of NIDDM and 11 cases of IDDM. Peak latency, interpeak latency (IPL) and peak amplitude of BAEPs were analyzed in each case. For further correlation, the moto...
متن کامل[Intraoperative monitoring of somatosensory evoked potentials].
Somatosensory evoked potentials (SEPs) were monitored during 20 operations, 13 for tumors in the posterior fossa and upper cervical region and seven for the treatment of aneurysms or carotid cavernous fistulae. Monitoring was technically satisfactory in 16 patients (80%). In two patients, monitoring was compromised by contamination with electrical noise. Two patients with mass le sions i...
متن کاملEffects of Acute Hypothyroidism on Brainstem Auditory Evoked Potentials (BAEPs)
Thyroid hormone deficiency is associated with peripheral and central nervous system (CNS) dysfunctions (1-9). CNS manifestations include somnolence, lethargy, mental retardation, memory changes, depression, and rarely convulsions and coma (10). The CNS involvement in overt hypothyroidism has previously been shown on the basis of visual evoked potentials in adult patients (11-13) and of BAEPs an...
