Background: auditory hypersensitivity in the autistic spectrum disorder has been described in the literature since the very first reports. However, this symptom has not been sufficiently explored, especially regarding possible causes, diagnosis and consequences.
Aim: to study sensory-perceptual abnormalities in the autistic spectrum disorder, emphasizing auditory hypersensitivity and to discuss their effects in speech therapy based on the literature found until September 2007 in the following database: Scielo, Lilacs, Web of Science, and Medline.
Conclusion: sensory-perceptual abnormalities are present in approximately 90% of individuals with autism; no theory has been found to explain this fact. Although the cause of auditory hypersensitivity remains unknown, it is the most common sensory-perceptual abnormality--its prevalence ranges between 15% to 100%. A few rare studies exist on behavioral, electroacoustic and electrophysiological hearing evaluation of autistic children; these studies discuss auditory hypersensitivity. The early diagnosis of this alteration is considered relevant for the possible identification of atypical sensorial markers, especially in hearing and for the better understanding of their impact on the development of communication in autistic individuals.

There is evidence to suggest that sensory processing differences (SPDs) to external stimuli are a plausible underlying mechanism for mental health problems among autistic people. In the current systematic review, we examined the associations between, on the one hand, eleven types of SPDs and, on the other hand, internalising and externalising problems. The literature search was conducted on five databases (MEDLINE, PsycINFO, Web of Science, EMBASE, and CINAHL) between 1990 and August 2024.

Auditory dysfunction affects the vast majority of people with autism spectrum disorder (ASD) and can range from deafness to hypersensitivity. exposure to the antiepileptic valproic acid (VPA) is associated with significant risk of an ASD diagnosis in humans and timed exposure to VPA is utilized as an animal model of ASD. VPA-exposed rats have significantly fewer neurons in their auditory brainstem, thalamus and cortex, reduced ascending projections to the midbrain and thalamus and reduced descending projections from the cortex to the auditory midbrain.

Intravenous amikacin, recommended for severe or recurrent (MAC) infections and as initial treatment for lung disease, is often limited by serious adverse effects such as renal and auditory toxicities. Inhaled Amikacin Liposome Inhalation Suspension (ALIS) enhances pulmonary drug deposition while minimizing systemic adverse effects, and it has recently been introduced as an add-on therapy for refractory MAC infections or when other standard treatments are inadequate. This study aims to retrospectively describe the outcomes of Greek patients with difficult-to-treat non-tuberculous mycobacterial (NTM) lung disease following the addition of ALIS to guideline-based therapy.

Auditory processing is widely understood to occur differently in autism, though the patterns of brain activity underlying these differences are not well understood. The diversity of autism also means brain-wide networks may change in various ways to produce similar behavioral outputs. We used larval zebrafish to investigate auditory habituation in four genetic lines relevant to autism: , , and .

The rapid development and clinical application of sequencing technologies enable the genetic diagnosis of inherited deafness. P2RX2, as the gene responsible for autosomal dominant non-syndromic deafness-41 (DFNA41), has been proven to be essential for life-long normal hearing and for the protection of noise-induced hearing loss (NIHL). Our present study reports a missense variant in the P2RX2 gene (c.
