Pelizaeus-Merzbacher disease (PMD) is an X-linked recessive rare disease condition in which audiological deficit is also observed. A 4-year-old male child with PMD underwent an audiological evaluation. The results suggested normal middle ear and outer hair cells functioning, with only peak I of the auditory brainstem response present until 30 dBnHL.

Background: In India, persons with hearing impairment who benefit from hearing aids can acquire a driving license. The law mandates helmet use while driving two-wheelers. Using a hearing aid with a helmet on may be a challenge, but it is paramount to understand the difficulties the hearing aid users face.

The vestibular system is a complex network between peripheral and central mechanisms. This innate complexity of the vestibular system necessitates objective test procedures for evidence-based diagnostic formulations and intervention.

Although vestibular dysfunction is reported in SS, limited information is available underlying the vestibular pathophysiology.
Method: The diagnosis of SS was established based on symptoms and diagnostic tools such as magnetic resonance imaging and fundus fluorescein angiography.
Background And Purpose: The National Institute of Health Stroke Scale (NIHSS) is widely used in clinical practice to evaluate stroke-related neurological deficits. The aim of this study was to develop Kannada language version of the NIHSS (Ka-NIHSS) and determine its validity and reliability.
Materials And Methods: In the first phase of the study, Ka-NIHSS was adapted based on cultural and linguistic peculiarities.
Background: Charcot-Marie-Tooth disease type 4F (CMT4F) is an autosomal recessive disorder with symptoms presenting in early adulthood. This clinical case series demonstrates atypical findings in cervical and ocular vestibular evoked myogenic potentials (VEMP) in siblings with CMT4F.
Purpose: The aim of this study was to highlight the audiovestibular test findings in CMT4F.
Context: Temporal lobe epilepsy can affect central auditory processing (CAP) skills. Auditory temporal ordering (ATO) is a CAP skill that can be evaluated using duration pattern test (DPT).
Aim: The aim is to evaluate ATO in patients with medial temporal lobe epilepsy (MTLE) with hippocampal sclerosis (MTLE + HS) and without hippocampal sclerosis (MTLE-HS) and in their subgroups.
Pilocytic astrocytoma commonly occurs in children and depending on the extension of the lesion may cause varied audiovestibular dysfunctions. However, audiovestibular findings are scarcely reported in the literature. Audiovestibular testing was performed on a single subject on two occasions pre-surgically.

This case report documents an atypical abnormality of the cervical vestibular evoked myogenic potential (cVEMP) in a patient with schwannoma of the hypoglossal nerve. The observed abnormality was attributed to the proximity of the hypoglossal nerve to the spinal accessory nerve in the medullary cistern and base of the skull.
