New Computer Model May Explain Spread of Seizures in the Brain

Posted 11 Sep 2016 in Brain science; genetics

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

Posted 9 Sep 2016 in Brain science; genetics

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

A Possible Explanation as to Why Some Children Outgrow Epilepsy in Adolescence

Posted 30 Aug 2016 in Brain science; genetics

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

Prolonged status epilepticus is linked to brain wasting

Posted 17 Aug 2016 in Brain science; genetics

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
