Autism Spectrum Disorder

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.

Hypersensitivities

Hypersensitivities

Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Hearing

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Auditory Pathway

Auditory Pathway

Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking the...

Modeling in Therapy

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
Participant Modeling
Participant modeling involves therapists demonstrating calm and effective behaviors in situations...

Summary

Auditory hypersensitivity is common in autism spectrum disorder (ASD), affecting up to 100% of individuals. Early diagnosis is crucial for understanding its impact on communication development in autistic children.

Neuroscience
Developmental Psychology
Speech-Language Pathology

Background:

Auditory hypersensitivity is a frequently reported symptom in autism spectrum disorder (ASD).
Despite its prevalence, this symptom remains underexplored concerning its causes, diagnosis, and consequences.
Existing literature highlights sensory-perceptual abnormalities in approximately 90% of individuals with autism.

Purpose of the Study:

To investigate sensory-perceptual abnormalities in ASD, with a focus on auditory hypersensitivity.
To review the effects of auditory hypersensitivity on speech therapy.
To synthesize findings from literature published up to September 2007.

Main Methods:

Literature review of databases including Scielo, Lilacs, Web of Science, and Medline.
Analysis of studies on behavioral, electroacoustic, and electrophysiological hearing evaluations in autistic children.
Focus on research concerning auditory hypersensitivity in ASD.

Main Results:

Auditory hypersensitivity is the most common sensory-perceptual abnormality in ASD, with prevalence estimates ranging from 15% to 100%.
The underlying causes of auditory hypersensitivity in ASD remain unknown.
Limited studies exist on the comprehensive evaluation of hearing in autistic children regarding hypersensitivity.

Conclusions:

Sensory-perceptual abnormalities are highly prevalent in individuals with ASD.
Early diagnosis of auditory hypersensitivity is vital for identifying atypical auditory markers.
Understanding auditory hypersensitivity is key to improving communication development and speech therapy outcomes in autistic individuals.
