Insights

Sensory processing issues in fragile X syndrome (FXS) emerge early and worsen through preschool. Early intervention for these sensory challenges in children with FXS is crucial.

Area of Science:

  • Neurodevelopmental disorders
  • Pediatric sensory processing
  • Fragile X syndrome research

Background:

  • Fragile X syndrome (FXS) is a genetic disorder associated with developmental challenges.
  • Longitudinal data on sensory processing development in FXS is lacking.
  • Understanding sensory processing trajectories is vital for early intervention.

Purpose of the Study:

  • To investigate the developmental trajectories of sensory processing in boys with FXS from infancy to preschool.
  • To identify correlates of sensory processing differences in this population.
  • To establish a baseline for future FXS sensory processing research.

Main Methods:

  • Longitudinal study design involving 13 boys with FXS.
  • Data collected 2-6 times between 9 and 54 months of age.
  • Utilized observational and parent-report measures for sensory processing assessment.

Main Results:

  • An increasing number of boys with FXS showed atypical sensory processing over time.
  • Observational methods were more sensitive than parent reports in early infancy.
  • Developmental quotient and age predicted hyporesponsiveness; hyperresponsiveness tended to increase with age.

Conclusions:

  • Sensory processing deficits in FXS are evident early and escalate through preschool years.
  • Early identification and intervention strategies are recommended to mitigate long-term impacts.
  • Findings highlight the need for targeted support for sensory needs in children with FXS.

Autism Spectrum Disorder01:19

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.
Pleiotropy01:33

Pleiotropy

Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
Sex-linked Disorders01:43

Sex-linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
Sensory Modalities01:15

Sensory Modalities

Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...
Overview of Somatic Sensory Pathways01:29

Overview of Somatic Sensory Pathways

Somatic sensory or somatosensory pathways refer to the neural pathways that carry information related to touch, pressure, pain, temperature, and proprioception from the skin, muscles, tendons, and joints to the brain. These pathways involve several stages of processing and integration of sensory information.
The somatosensory system is divided into three main pathways: the dorsal (or posterior) column-medial lemniscus, spinothalamic (or anterolateral), and spinocerebellar pathways.
The dorsal...
