Researchers have identified a unique metabolic signature associated with epileptic brain tissue that causes seizures. The chemical biomarker can be detected noninvasively using technology based on magnetic resonance imaging. It will allow physicians to precisely identify small regions of abnormal brain tissue in early-stage epilepsy patients that can’t be detected today using current technology. The biomarker could also be used to localize epileptic brain regions for therapeutic removal without the need for additional surgery.
Sometimes Shelby would be there, but not “all there.” At the dinner table, her parents and siblings would catch her “zoning out”; she’d stop paying attention to the conversation and need to be jostled back to focus. They’d chide her for being so rude, then continue with their meal. It was just one of her quirks, they reasoned, and she’d grow out of it eventually.
Childhood abuse, both sexual and emotional, is more frequently reported in epilepsy patients when compared to the general population, according to the results of a German study. These findings are in agreement with previous studies and highlight the need for additional vigilance on the familiar settings of children with epilepsy.
The first “Bachelorette” Trista Sutter continues to live with unanswered questions about her health, after suffering some kind of seizure while vacationing with her family in Croatia last month. The 44-year-old mother of two opened up about her heath scare in an interview Tuesday morning on ABC’s “Good Morning America.” With her husband Ryan Sutter by her side, she said she had no symptoms of illness before the seizure. She said she has enjoyed a healthy and active lifestyle. Her only health problems, if you can call them that, have been the occasional headache.
Researchers at the UT Southwestern Medical Center in Dallas have discovered that more than 100 genes are linked to memory processing in the brain. The discovery could lead to the development of new therapies for memory-associated conditions such as epilepsy, Alzheimer’s, and others, the study’s authors said.
Epilepsy is a disease that disrupts the electrical activity of the nervous system, causing seizures. More than 65 million people in the world have epilepsy. 1 in 26 Americans will develop the disease during their lives. Children are the group most frequently diagnosed with new cases of epilepsy. In the United States, 300,000 children under 14 are affected by the condition. Some may outgrow the disorder, but most will not. The number of senior citizens with epilepsy is also 300,000. People with epilepsy have a range of treatment options, including alternative therapies. The illness is a complex condition, however, and all alternative treatment options must be looked at carefully, to ensure they are effective. Causes of epilepsy Epilepsy is a complex disease that can disrupt the electrical a...
Many neurological diseases are malfunctions of synapses, or the points of contact between neurons that allow senses and other information to pass from finger to brain. In the brain, there is a careful balance between the excitatory synapses that allow messages to pass, and the inhibitory synapses that dampen the signal. When that balance is off, the brain becomes unable to process information normally, leading to conditions like epilepsy.
Snapping a selfie may come with an unwanted side effect, at least for one teen. In a recent case report from Canada, doctors saw seizure-like activity in a teen’s brainwaves just after the teen took a selfie. The doctors who treated the teen called the phenomenon “selfie-epilepsy,” according to the report, which was published in February in the journal Seizure.
Researchers at the Max Planck Florida Institute for Neuroscience identify the wiring process of a unique type of inhibitory cells implicated in several diseases. A basic tenet of neural development is that young neurons make far more connections than they will actually use, with very little specificity. They selectively maintain only the ones that they end up needing. Once many of these connections are made, the brain employs a use-it or lose-it strategy; if the organism’s subsequent experiences stimulate the synapse, it will strengthen and survive. If not, the synapse will weaken and eventually disappear.
In a pair of studies, scientists at the National Institutes of Health explored how the human brain stores and retrieves memories. One study suggests that the brain etches each memory into unique firing patterns of individual neurons. Meanwhile, the second study The studies were led by Kareem Zaghloul, M.D., Ph.D., a neurosurgeon-researcher at the NIH’s National Institute of Neurological Disorders and Stroke (NINDS). Persons with drug resistant epilepsy in protocols studying surgical resection of their seizure focus at the NIH’s Clinical Center enrolled in this study. To help locate the source of the seizures, Dr. Zaghloul’s team surgically implanted a grid of electrodes into the patients’ brains and monitored electrical activity for several days.
A study conducted in the US has hit upon a new strategy to identify genes that underlie specific brain processes, and may eventually help scientists develop treatments for patients with memory impairments. More than 100 genes linked to memory have been identified, paving the way for treatments for conditions like epilepsy and Alzheimer’s disease.
Most people are aware that flashing and strobe lights can trigger a seizure in some individuals with epilepsy, but few realize that certain still images can have the same effect. Doctors have remained puzzled as to why certain motionless photos can trigger seizures, but now new research has unveiled the reason. A study published in Current Biology found certain patterns can trigger a specific part of the brain, causing gamma-oscillation, which in some cases, can induce a seizure.
