Brainstem auditory evoked potentials (BAEPs) were recorded in a group of 22 children hospitalized for the treatment of severe malnutrition (kwashiorkor). Recordings were repeated after three weeks of treatment. The control group consisted of age- and sex-matched healthy infants. Abnormal BAEP interpeak-latencies (IPLs) were found in 32% of the kwashiorkor group in the initial recording and in 40% of this group in the follow-up recording. Abnormalities were evenly distributed between the I-III, III-V and I-V IPLs and in the majority of cases were unilateral. The influence of increasing stimulus rate was investigated. The findings may reflect defects in myelination of auditory brainstem pathways, however, BAEP abnormalities were not related to several indices of growth retardation or to serum albumin and hemoglobin levels.

Tinnitus is the perception of sound without an external source, often associated with changes in the auditory pathway and different brain regions. Recent research revealed an overload of missense variants in the ANK2 gene in individuals with severe tinnitus. ANK2, encoding ankyrin-B, regulates axon branching and inhibits microtubule invasion.

Loud noise exposure is one of the leading causes of permanent hearing loss. Individuals with noise-induced hearing loss (NIHL) suffer from speech comprehension deficits and experience impairments to cognitive functions such as attention and decision-making. Here, we investigate the specific underlying cognitive processes during auditory perceptual decision-making that are impacted by NIHL.

Sensorineural hearing loss (SNHL) is an increasingly prevalent sensory disorder, but the underlying mechanisms remain poorly understood. Adaptor related protein complex 2 subunit beta 1 (AP2B1) has been indicated to be detectable in mature cochleae. Nonetheless, it is unclear whether AP2B1 is implicated in the progression of SNHL.

An 11-year-old male Bengal tiger () was referred for a 2-week history of ambulatory tetraparesis, generalized ataxia, and hypermetric gait, associated with mild right head tilt and spontaneous proprioceptive deficit on the right forelimb. Neuroanatomical localization was C1-C5 myelopathy; cerebellum-vestibular system involvement was also considered. Hematology and serum biochemistry were unremarkable, although serum vitamin A (0.
