UNLABELLED Brainstem Evoked Response Audiometry (BERA) is an objective and non-invasive method of hearing assessment which detects electrical activity from the inner ear to the inferior colliculus. AIM To assess the hearing pathway in normal hearing individuals and compare differences associated with gender, age and ear side (left and right). STUDY DESIGN A retrospective study. MATERIALS ...

UNLABELLED Otoneurological evaluations are based on tests which investigate auditory and vestibular disorders, including brainstem evoked auditory potentials and vecto-electronystagmography. AIM to describe the results from the otoneurological assessment of patients with vestibulocochlear complaints, normal hearing individuals and patients with hearing loss, and we will compare them to a cont...

A patient with a brainstem tumor presented with astereognosis. The results of CT scan, evoked response studies, and neuropsychological tests all were consistent with a noncortical origin for the sensory defect.

BACKGROUND To characterize the findings of brainstem auditory evoked potential in HIV-positive individuals exposed and not exposed to antiretroviral treatment. MATERIAL AND METHODS This research was a cross-sectional, observational, and descriptive study. Forty-five HIV-positive individuals (18 not exposed and 27 exposed to the antiretroviral treatment - research groups I and II, respectively...

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...

Brainstem auditory evoked response (BAER) is a reliable test for neonatal auditory and neurological dysfunction and it permits early diagnosis and rehabilitation. The purpose of this study is to demonstrate latencies of BAER in normal term neonates in order to obtain reference values in a university hospital. BAER was performed in the second day of life in 47 normal newborns (25 male, 22 female...

OBJECTIVE The speech-evoked auditory brainstem response (ABR) provides an objective measure of subcortical encoding of complex acoustic features. However, the intrasubject reliability of this response in both optimal and challenging listening conditions has not yet been systematically documented. This study aimed to evaluate test-retest reliability of the speech-evoked ABR in young adults. ME...

During our study of recording auditory evoked potentials in protein-calorie malnutrition in infants and young children (1), we came across a few cases of anaemia. The heamatological investigationsincluding haemogram, showed that, of the five cases, two had megaloblastic anaemia, two had microcytic hypochromic and one had severe aplastic anaemia. Such neurological complications of various types ...

Conversion disorder is characterized by the presence of one or more neurological or general medical symptoms that cannot be explained by a known neurological or medical disorder (1). Several studies have reported that 5 to 15 percent of psychiatric consultations in a general hospital involve patients with conversion disorder diagnosis (2). This disorder frequently occurs in the context of other...

Under adequate stimulus intensities, the power spectra of normal auditory evoked brainstem responses (ABR) are mainly composed of three major parts, i.e. component A (0 approximately 350Hz), B (350-700Hz). and C (700-1200Hz). By means of digital filter using fast Fourier transform, three derived ABR waveforms consist of each component of the power spectrum were obtained and named component wave...
