Article Synopsis
  • This study investigates sensory symptoms (SS) and hyperarousal signs (HA) in individuals with fragile X syndrome (FXS), analyzing data from a large registry to understand their impact from childhood to early adulthood and by gender.
  • Findings reveal that males experience more severe SS and HA compared to females, with strong sensory responses correlating to higher rates of behavioral issues and comorbidities.
  • The research highlights a shift in treatment approaches with age, showing decreased use of non-medication therapies and increased reliance on psychopharmacological treatments, emphasizing the need for further studies on how SS and HA contribute to behavioral difficulties in FXS.

Integration of occupational therapy into a camp environment may support participation for children with neurodevelopmental differences, but evidence is limited. This study examines the effects of participation of children with regulation/sensory processing differences at one such integrated camp on parent-established functional goals. We used a pre-test/post-test repeated measures cohort design.

Cerebral arteriovenous malformations (AVMs) present a challenge to diagnose in children with developmental disability, because of the overlap in behavioral symptoms and neurologic manifestations. They have been very rarely reported in conjunction with autism spectrum disorder. This case involves a 13 year old male with a history of autism spectrum disorder and significant behavioral issues diagnosed with a thalamic AVM following lateralizing neurologic symptoms.

Background And Objective: Individuals with fragile X syndrome (FXS) are frequently codiagnosed with autism spectrum disorder (ASD). Most of our current knowledge about ASD in FXS comes from family surveys and small studies. The objective of this study was to examine the impact of the ASD diagnosis in a large clinic-based FXS population to better inform the care of people with FXS.

Background: The present study sought to examine the specificity, developmental correlates, nature and pervasiveness of imitation deficits very early in the development of autism.

Methods: Subjects were 24 children with autism (mean age 34 months), 18 children with fragile X syndrome, 20 children with other developmental disorders, and 15 typically-developing children. Tasks included manual, oral-facial, and object oriented imitations, developmental measures, joint attention ability, and motor abilities.

Seven-month-old infants appear to learn means-end skills, such as pushing a button to retrieve a distant toy (Psychological Review 104 (1997) 686). The present studies tested whether such apparent means-end behaviors are genuine, or simply the repetition of trained behaviors under conditions of greatest arousal, as suggested by a dynamic systems reinterpretation. When infants were trained to repeat behaviors that did not serve as means to retrieving toys (pushing a button to light a set of distant lights), their button-pushing differed significantly from infants for whom button-pushing served as a means for retrieving toys.
