First Author Zoya Bastany, a masters student at the University of British Columbia, comments: “Using this method, we found that the electrical signals read more
Machine Learning Could Help The Diagnosis of Drug-Resistant Epilepsy
‘Machine learning’, a type of computer modelling, can detect areas of brain damage (lesions) associated with drug-resistant epilepsy. This is according to a new study published in the scientific journal PLOS One. During the study, researchers led by Dr Carole Lartizien, from the University of Lyon, developed a complex system that is able learn features associated with healthy brain MRI scans. It can then read more
New Computer Model May Explain Spread of Seizures in the Brain
Researchers at the University of Pennsylvania have developed a new computer model that may explain why some seizures spread throughout the brain whilst others stay localized. The seizure networks model, which the scientists developed using direct recordings from the brain of people with epilepsy, proposes that, whereas some regions in the brain promote seizure activity, others dampen it. The leader of the read more
3D Structure of Brain Receptor Could Help Develop Better Epilepsy Drugs
Researchers at Columbia University Medical Center have described, in detail, the structure and function of a type of receptor called the AMPA receptor. This plays an important role in the activation of neurons, but in epilepsy it contributes to seizure spread. Currently there is only one approved drug, known as perampanel, that inhibits AMPA receptors to try and stop seizures. However, because read more
An Important breakthrough for infantile epilepsies
Scientists at the University of Queensland have made an important discovery about severe infantile epilepsies, which, unexpectedly, links to Parkinson’s disease. The results are published in the Journal of Cell Biology. According to Professor Frédéric Meunier, Senior Author on the study, this discovery could open new avenues for the development of different classes of drugs to treat epilepsy. In a press release, Dr Emma read more
A Possible Explanation as to Why Some Children Outgrow Epilepsy in Adolescence
Results from the US and China may help to explain why 50-60% of children with epilepsy outgrow their condition in adolescence. At the heart of these findings is ‘GABA’; a brain chemical that acts via structures called receptors to dampen down electrical activity in neurons (and prevent them from becoming over-excited). Recent evidence shows that there is a specific type of GABA read more
Grey Matter Loss Differs in Right and Left Temporal Lobe Epilepsy
In people with temporal lobe epilepsy (TLE), grey matter – the darker part of the brain that consists of densely packed nerve cell bodies – becomes reduced in particular areas. A recent study, published in the Journal of Clinical Neurology, has now shown that this decrease is more pronounced in people with right-sided TLE than in those with left-sided TLE. read more
Prolonged status epilepticus is linked to brain wasting
Brain atrophy, or wasting, and re-organisation of neurons occur in the brains of people with super-refractory status epilepticus (SRSE), according to a study published in JAMA Neurology. The research also shows that the severity of brain atrophy is related to the duration of SRSE. This is the first study to show that brain atrophy occurs even after difficult-to-treat status epilepticus is controlled with anaesthetic drugs. read more
An exciting advance for the study of epilepsy
Researchers in Singapore have improved the production high quality, functional human inhibitory (‘GABAergic’) neurons in the laboratory, according to a study published in the leading journal Cell. These neurons can now be used to develop models to study epilepsy, as well as other neurological conditions. They can also be used to screen the effects of antiepileptic drugs (AEDs) without the need to read more
Dystrophin Protein may be a Potential Treatment Target for Epilepsy
The hippocampal form of an essential muscle protein called dystrophin is found in higher levels in people with temporal lobe epilepsy (TLE), according to a new study published in the scientific journal Frontiers in Cellular Neuroscience. This could be the result of a compensatory mechanism – in response to too much excitation in the brain (hyperexcitation) – that tries to restore the read more
Eye Movements Could be Used as a Measure of Epilepsy Progression
Research published in the scientific journal PLOS One suggests that children with epilepsy have irregularities in their pattern of saccadic eye movement. This refers to the fast, jerking movement of the eyes that allows people to scan their environment and build a mental 3D image of it. According to the authors of the study, these irregularities may be indicative of abnormal read more
