Brainstem auditory evoked responses (BAERs) were recorded in 40 patients with clinically definite brainstem infarction, and results were compared to localizations from physical signs and CT scans. The BAER was abnormal in 92% of patients with evidence on physical examination of dysfunction of lateral structures in the pons or midbrain. Normal BAERs were seen with medially-situated or medullary ...

In two newborn infants who had experienced severe asphyxial insults, and who showed noticeable signs of brainstem dysfunction, all components of the auditory brainstem response except the eighth nerve potential became undetectable. Both babies survived, their brainstem responses returned, and one of them is judged to be developmentally normal at the age of 18 months. Clinical signs of brainstem...

Background: Brainstem hemorrhage was first described by Cheyne in 1812 in a pathological study of patients presenting with lethargy and coma. In 1877 Bode reviewed the findings of 67 patients reported in the literature (1). In the United States, the incidence of closed head injury is estimated to be approximately 200 cases per 100,000 persons per year. The financial burden of head injuries in...

In an attempt to assess objectively the integrity of the auditory pathways in 30 patients with definite multiple sclerosis (MS), an audiometric evaluation was performed and auditory brainstem responses (ABRs) were obtained. Stressing the auditory system by increasing the stimulation rate showed some enhancement in the identification of MS. 24 (RO%) patients had an abnormal ABR along with c...

Adolescent Idiopathic Scoliosis (AIS) characterized by the 3D spine deformity affects about 4% schoolchildren worldwide. Several studies have demonstrated the malfunctioning of postural balance, proprioception, and equilibrium control in patients with AIS. Since these functions are closely related to structures in and around the brainstem, the morphometry of the brainstem surface is of utmost i...
