An evolutionary tree of more than 161 dog breeds has been mapped out by geneticists, showing which types are closely related to each other. The research will be of obvious interest to dog owners but it is hoped it will shed light on the causes of diseases that affect both dogs and humans, including epilepsy.
Tiny, 3-D clusters of human brain cells grown in a petri dish are providing hints about the origins of disorders like autism and epilepsy. An experiment using these cell clusters — which are only about the size of the head of a pin — found that a genetic mutation associated with both autism and epilepsy kept developing cells from migrating normally from one cluster of brain cells to another, researchers report in the journal Nature.
There is an uncommon risk of death that people with epilepsy and their loved ones may not know about. The risk is called sudden unexpected death in epilepsy, or SUDEP. Now the American Academy of Neurology (AAN) and the American Epilepsy Society have co-developed a new guideline on SUDEP, published in the April 24, 2017, online issue of Neurology®, the medical journal of the American Academy of Neurology, and presented at the 69th AAN Annual Meeting in Boston, April 22 to 28, 2017. The guideline is endorsed by the International Child Neurology Association. SUDEP is when someone with epilepsy who is otherwise healthy dies suddenly with no known cause.
For individuals with a severe form of epilepsy, a new study finds that the occurrence of seizures could be significantly reduced with a daily dose of cannabidiol – a chemical component of cannabis. Researchers say that cannabidiol – an active chemical in cannabis – could help to reduce seizures for patients with Lennox-Gastaut syndrome. Researchers from the Ohio State University found that individuals with Lennox-Gastaut syndrome (LGS) who took cannabidiol every day for 14 weeks saw the frequency of atonic seizures fall by more than 50 percent. Atonic seizures, also known as drop seizures, involve a sudden, brief loss of muscle tone. Study co-author Dr. Anup Patel, of the College of Medicine at Ohio State, and colleagues recently presented their findings at the American A...
For the first time in almost three decades, the classification for epileptic seizures has been updated. The new system formally recognizes some seizure types, provides additional information on causes, and replaces obscure or questionable words and terms with more meaningful ones, the authors say.
We are often judged by the company we keep, even unfairly. For decades, that has been the fate of cannabidiol, a chemical compound that has the bad luck to occur naturally in marijuana, the world’s most controversial plant. Because cannabidiol is subject to the same tight legal restrictions on personal and scientific use as is marijuana, its potential medical benefits have been underappreciated — at least up until now.
More than 50 million people of all ages suffer from epilepsy, otherwise known as seizure disorder, the fourth most common neurological disease in the world. Patients diagnosed with epilepsy often experience recurrent seizures triggered by the firing of a large collection of neurons in the brain. This ultimately generates a high-energy wave that spreads across the surface of the brain, resulting in numerous physical effects such as erratic body shaking, unconsciousness, exhaustion, and pain.
There is a growing interest over the possible relationship between depression and epilepsy. A study recently published showed that there is an increased risk of developing epilepsy among persons diagnosed with depression, and vice versa. Epilepsy is a syndrome characterized by recurrent, unprovoked seizures due to an imbalance of chemicals in the nervous system. This chemical imbalance is also one of the underlying mechanisms of depression. This similarity in pathophysiology has sparked an interest among the medical community to determine the possible relationship between the two diseases.
New King’s College London research reveals how genetic defects can lead to epilepsy in children. In their new study, published in Scientific Reports and funded by Eli Lilly and Co., the researchers set out to understand how genetic defects affect electrical transmission in the brain. Understanding exactly how nerve cells are misfiring and creating seizures in children with epilepsy will allow researchers to design better, more personalised treatments for epilepsy.
Prolonged epileptic seizures may cause serious problems that will continue for the rest of a patient’s life. As a result of a seizure, neural connections of the brain may be rewired in an incorrect way. This may result in seizures that are difficult to control with medication. Mechanisms underlying this phenomenon are not entirely known, which makes current therapies ineffective in some patients.
Neurological diseases are best studied using human neurons, and a longtime goal — once thought impossible — has been to grow such neurons in the lab. Now researchers have su cceeded, maintaining adult neurons in culture for months, an achievement that opens a way to better understand how epilepsy treatments affect the brain.
Medtronic plc (NYSE: MDT) announced today that the first procedure using the Visualase(TM) MRI-Guided Laser Ablation System has been performed in the pivotal SLATE (Stereotactic Laser Ablation for Temporal Lobe Epilepsy) clinical trial at Mayo Clinic in Rochester, Minn.
