Responsive Neurostimulator System: An implantable device to treat epilepsy
About 2.5 million Americans of all ages have epilepsy. Think of it as a tiny electrical storm in the brain. Many people suffer from seizures affecting their quality of life or have side effects from epilepsy medications. However, patients with some types of the disease don't respond to surgery or may be at high risk for complications. That's why new devices surgically implanted in the brain itself offer hope for an effective epilepsy treatment.

Septum sets the tempo of brain's electrical activity
The brain's septum helps prevent epileptic seizures by inducing rhythmical electrical activity in the circuits of another area of the brain known as the hippocampus, according to a new study in the Journal of Neurophysiology. The researchers found that, by imposing a normal "theta" rhythm on chronically epileptic rats, they could reduce epileptic seizures by 86-97 percent.

Computerized atlas highlights brain structure changes in Williams syndrome
A computerized atlas has brought unprecedented sensitivity to the search for brain structure changes in a genetic condition known as Williams syndrome, revealing 33 abnormalities in the folding of the brain's surface. The disorder, which occurs in 1 in every 20,000 births, impairs visual and spatial skills but preserves musical ability and sociability.

Multiple-stage surgery brings hope for Tuberous Sclerosis with intractable seizures
Sadly, none of the treatments for epilepsy�anti-seizure medications, a procedure called vagus nerve stimulation, a special diet �could quell the electrical storms in the young boy�s brain. Caused by a rare genetic disease called tuberous sclerosis, the seizures began when he was only 2 months old. By the time he was 5, he was having more than 10 a day. The seizures left him with the developmental capabilities of a 1-year-old child.

Brain Gene Expression Map (BGEM) - Powerful new tool for studying brain development
Scientists at St. Jude Children's Research Hospital have given investigators around the world free access to a powerful tool for studying brain development. The Internet-based tool, called the mouse Brain Gene Expression Map (BGEM), is one of the largest gene expression maps of an organ ever developed, according to the St. Jude researchers. They say the map will likely help scientists discover the genetic origins of brain cancers, which could speed development of novel drugs to treat them.

Flexible Drug Dosing in Epilepsy Reduces Side Effects
For the first time, researchers compared dosing regimens of an antiepileptic drug (AED) used for treatment of partial epilepsy in adults, in conjunction with other AEDs. They looked at dosing used in clinical everyday life (flexible dosing) and that used in classical clinical trials (fixed dose) and discovered that the flexible dosing method was superior. Researchers observed how patients responded to these two methods of dosing therapy over a 12-week period. According to the researchers, while clinical trials have traditionally used fixed doses throughout a treatment period, clinical practice allows for the gradual adjustment of medication dose to enhance patient tolerability and enable optimum effective dosing, based on individual patient response.

New technology to help children with cerebral palsy
Biomedical engineers at New Jersey Institute of Technology (NJIT) will use new technology to help children with cerebral palsy improve their movements, reduce stiffness in their joints and live fuller and more independent lives. Small robots mounted on wheelchairs, interactive video games and a robotic arm that can be programmed to guide and aid human motion � these are just a few of the technologies the engineers will use to help these children improve their muscular control and movements.

Ketogenic diet prevents seizures
Although the high-fat, calorie-restricted ketogenic diet (KD) has long been used to prevent childhood epileptic seizures that are unresponsive to drugs, physicians have not really understood exactly why the diet works. New studies by a research team at Emory University School of Medicine show that the diet alters genes involved in energy metabolism in the brain, which in turn helps stabilize the function of neurons exposed to the challenges of epileptic seizures. This knowledge could help scientists identify specific molecular or genetic targets and lead to more effective drug treatments for epilepsy and brain damage.

Blood Test Can Help Determine Type of Seizure
Using a blood test to measure the level of the hormone prolactin can help determine, in certain clinical settings, whether an epileptic seizure has occurred, according to a guideline developed by the American Academy of Neurology and published in the September 13, 2005 issue of Neurology. The guideline authors reviewed all of the scientific evidence available on use of the prolactin blood test to diagnose seizures and developed evidence-based recommendations.

Propofol is effective in pediatric refractory status epilepticus
Propofol is a safe and effective drug to treat children with refractory status epilepticus, and it is recommended before thiopental, according to a study in the August 23, 2005 issue of Neurology, the scientific journal of the American Academy of Neurology. Propofol and thiopental are widely used intravenous anesthetics which are also known to help control seizures.

Astrocytes appear to play a key role in development of epilepsy
Star-shaped brain cells that are often overlooked by doctors and scientists as mere support cells appear to play a key role in the development of epilepsy, researchers say in a study published on-line August 14 in Nature Medicine. It's one of the first times scientists have produced firm evidence implicating the cells, known as astrocytes, in a common human disease.

Noninvasive evaluation of epilepsy patients prior to surgery- Funtional MRI
Brain surgery is a treatment option for epileptic patients who fail to respond to medical therapy.Prior to surgery, the epileptic focus and its proximity to important funtional areas needs to be identified . This was done in the past by invasive tests likethe Wada test and electrical cortical mapping.Functional MRI, which uses radio waves and a strong magnetic field, is a non-invasive test capable of identifying the location of critical brain functions that could be affected by the location of the seizure focus.
