New ’eye movement’ test may help treat fetal alcohol syndrome

14.11.2005


Tool is more objective, accurate in identifying children affected by



A simple test that measures eye movement may help to identify children with Fetal Alcohol Spectrum Disorder (FASD) and ultimately lead to improved treatment for the condition, say Queen’s University researchers.

At present there are no objective diagnostic tools that can be used to distinguish between children with FASD – which affects approximately one per cent of children in Canada – and those with other developmental disorders such as Attention-Deficit Hyperactivity Disorder (ADHD).


Researcher James Reynolds and graduate student Courtney Green, of the Department of Pharmacology and Toxicology and the Centre for Neuroscience Studies, will present their findings next week at the annual meeting of the international Society for Neuroscience in Washington, D.C.

"Having a set of tests that can be used as diagnostic tools for fetal alcohol syndrome and all of the other behavioural disorders classified under the broader term fetal alcohol spectrum disorder is tremendously valuable," says Dr. Reynolds, who is part of a $1.25-million Queen’s-led team focusing on fetal alcohol syndrome, funded by the Canadian Institutes of Health Research. "Now we can begin to identify specific deficits in these children."

Many of the behavioural tests used to assess children with FASD are geared to white, middle-class English-speaking people, notes Ms Green. "The biggest problem [in current tests] is cultural insensitivity," she says. "By measuring eye movement we can cut across cultural barriers and provide objectivity in identifying the disorder."

In a pilot study involving 25 girls and boys aged eight to 12, the Queen’s team found that children with FASD have specific brain abnormalities which can be measured with eye movement testing. Defined as "birth defects resulting from a mother’s consumption of alcohol during pregnancy", fetal alcohol syndrome is associated with hyperactivity, difficulty in learning and deficits in memory, understanding and reasoning, as well as problems dealing with stressful situations.

The next stage of the Queen’s research will be to make the eye movement test mobile and transport it to targeted areas, such as northern and rural parts of Ontario, where FASD is believed to be more prevalent. The researchers envision this as a multi-centre project, in which other participants will work from the same set of pooled data.

"There is a clear need to develop new tools that can be used to reliably and objectively measure the brain injury of FASD," says Dr. Reynolds. "Ideally, these tools need to be mobile, inexpensive, and easy to use, for both diagnosis and the long-term evaluation of therapeutic interventions. Eye movements are ideally suited for this purpose."

Using the new functional MRI facility at Queen’s, the team will then be able to measure differences in brain activity between children with fetal alcohol syndrome and those with other developmental disorders such as ADHD.

"Having access to this facility will have a huge impact on our research program," Dr. Reynolds says. "It allows us to create an integrated research strategy for carrying out studies to provide functional brain imaging data that can be directly related to neuro-behavioural deficits in individual children with FASD."

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
