Language dysfunction in children may be due to epileptic brain activity

20.04.2010
Epileptic activity in the brain can affect language development in children, and EEG registrations should therefore be carried out more frequently on children with severe language impairment to identify more readily those who may need medical treatment, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg.

The thesis studied 60 children of varying ages, divided into groups. The first group comprised children with language dysfunction, for example children with slow speech development who find it difficult to express themselves or who have an inadequate langugage comprehension.

The second group consisted of children with epilepsy, while the third comprised children with language dysfunction and epileptic brain activity, sometimes without epileptic seizures. The study was carried out in conjunction with speech and language pathologists, pediatric neurologists and neuropsychologists at the Queen Silvia Children's Hospital in Gothenburg.

"We reviewed patient records of children with residual speech and language problems at school start, and could see that these children also had other underlying problems," says Gunilla Rejnö-Habte Selassie, speech and language pathologist and researcher at the Department of Clinical Neuroscience and Rehabilitation.

The study showed that epilepsy (with seizures) and epileptic brain activity with or without seizures were more common in these children than in children in general. The researchers then wanted to investigate whether the epileptic activity was the cause of the children's language dysfunction or whether other factors affected their language development.

"So we also looked at speech and language ability in preschool children with various forms of epilepsy," says Gunilla Rejnö-Habte Selassie. "We found that these children had certain language problems - they found it difficult to express themselves but had a good understanding of language."

The greatest problems were to be found in children with epileptic activity in the left side of the brain, which controls our linguistic ability.

The next step was to look at children with both speech and language dysfunction and epileptic brain activity in their sleep as young chidlren. and follow up their speech, language and other cognitive abilities after some years.

"We found that more than half the children of school age and young adults still had some form of language difficulties, while a few had normal linguistic abilities," says Gunilla Rejnö-Habte Selassie. "There was no difference between the children with continously slow language development and those who had experienced a loss or deterioration of their language - so called epileptic aphasia."

She concludes that more children with language dysfunction should be given EEG registrations to find an explanation for the underlying mechanisms, and so that the right care and treatment can be given. She also states that in some cases medical treatment could be considered to block the epileptic activity in the brain, and in this way reduce the impact on a child's language development.

"We hope that the results of our research will lead to a new way of looking at various diagnoses of language dysfunction and epileptic brain activity. More than anything, we need a completely new diagnosis for children with slow language development and epileptic brain activity."

EPILEPSY
Epilepsy takes the form of seizures, with or without the loss of consciousness and simultaneous convulsions. The seizures are due to temporary overactivation of the brain's electrical nerve impulses that can be registered with an electroencephalogram (EEG). Around 0.5 per cent of all children are estimated to have a tendency towards repeated epileptic seizures. The cause of epilepsy may be temporary or permanent damage to the brain, but a cause cannot always be identified. There are medicines to alleviate the symptoms.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
