Autism In Children Affects Not Only Social Abilities, But Also A Broad Range Of Sensory And Motor Skills

Autism In Children Affects Not Only Social Abilities, But Also A Broad Range Of Sensory And Motor Skills

......The thalamus is a crucial brain structure for many functions, such as vision, hearing, movement control and attention. In the children with autism, the pathways connecting the cerebral cortex and thalamus were found to be affected, indicating that these two parts of the brain do not communicate well with each other. 

"This impaired connectivity suggests that autism is not simply a disorder of social and communicative abilities, but also affects a broad range of sensory and motor systems," Müller said. 

.....While the findings reported in this study are novel, they are consistent with growing evidence on sensory and motor abnormalities in autism. They suggest that the diagnostic criteria for autism, which emphasize social and communicative impairment, may fail to consider the broad spectrum of problems children with autism experience. ....

After Mild Traumatic Brain Injury, Children With ADHD More Likely To Be Moderately Disabled

After Mild Traumatic Brain Injury, Children With ADHD More Likely To Be Moderately Disabled

.... [researchers]...found that 25% of the patients with ADHD had a moderate disability and 56% were completely recovered at the end of the follow-up period .... .....Statistical analysis in this study showed that "patients with ADHD were statistically significantly more disabled after mild TBI than were control patients without ADHD, even when controlling for age, sex, ...... children having greater disabilities requiring a longer follow-up period. ....

Call for Abstracts on Brain Injury

The abstract submission site for the
Tenth World Congress on Brain Injury is now open!
Hyatt Regency Embarcadero Hotel
San Francisco, California
March 19-22, 2014

 

Congress Overview

The International Brain Injury Association's World Congress is the largest gathering of international professionals working in the field of brain injury. Held biennially, delegates are comprised of physicians, psychologists and neuropsychologists, therapists, social workers, nurses, case managers, legal professionals, advocates and all others working in the field of brain injury. Over 1400 brain injury professionals attended the last World Congress in Edinburgh, Scotland, and we expect the San Francisco event to be larger still.
The Congress program will feature internationally recognized invited speakers, platform lectures, workshops, short oral presentations and poster sessions. The theme of the 2014 Congress is Neurotrauma, Technology, and Neurorehabilitation
Comments: I participated in this meeting in 2013 when it was held in Edinburgh, Scotland. It was awesome! If you have a paper/poster, please submit it today! Optometry should be represented. This fine group knows little about all we can do to improve the lives of patients with brain injury. DM

Where's Dominick?

This is a photo of many of the more than 100 researchers, clinicians and scientists who attended the 2013 Child Vision Research Society meeting at the University of Waterloo just outside of Toronto and also at the Hospital for Sick Children  in Toronto. The next meeting will be held in Prague in 2015. Hope to see you there!

Now than....where's Dominick?


Abnormality of vergence latency in children with vertigo

Abnormality of vergence latency in children with vertigo

It is well known that vergence movements are important for distance appreciation, depth vision and stereopsis. Moreover, vergence movements are very probably used by the CNS during head and body motion to adjust the gain of the vestibulo-ocular reflex (VOR) according to the viewing distance. ..... Orthoptic vergence training reduced all latencies; however, even the reduced latency of vergence and of combined movements was still abnormal. The improvement after orthoptic vergence training could be due to increased visual attention, although such mechanism cannot eliminate completely the initiation deficit of vergence movements. .....

Speed-accuracy of saccades, vergence and combined eye movements in children with vertigo

Speed-accuracy of saccades, vergence and combined eye movements in children with vertigo.

Vergence abnormalities could lead to inappropriate vestibulo-ocular reflex (VOR), causing vertigo and imbalance.... a recent study by Anoh-Tanon et al. ... reported the existence of a population of children with symptoms of vertigo in the absence of vestibular dysfunction but with abnormal vergence findings in orthoptic tests. .... children with vertigo perform saccades as normal subjects of comparable age. In contrast, vergence, particularly convergence, shows abnormalities: poor accuracy, long duration and low speed....... Orthoptic training improves significantly the accuracy of all eye movements; such improvement was significant for all types of eye movements except for divergence (pure and combined). Furthermore, convergence remains abnormal and the lack of acceleration by the saccade persists. These specific convergence deficits could be of both subcortical and cortical origin. Orthoptic training improves the accuracy presumably via visual attentional mechanisms, but cannot completely override deficits related to subcortical deficiencies.
