Two-thirds of women with catamenial epilepsy have diagnosis of partial epilepsy, study finds

In women of childbearing age with epilepsy, seizure exacerbation may occur either at the time of menstruation or ovulation. Investigators in a specialized epilepsy center have analyzed the data on a group of patients with seizures associated with their menstrual cycles (catamenial seizures) for type of epilepsy, seizure frequency, response to medication, neuroimaging findings, and seizures during pregnancy.

Conference to explore acute ischemic stroke treatment

Designed to serve a multidisciplinary audience of physicians, clinicians, and scientists interested in cerebrovascular disease, this 2.5-day conference will explore the state-of-the-art and future directions of research and clinical practice leading to enhanced medical care in the acute treatment of ischemic stroke.

First study to investigate risk factors for CCSVI in patients without neurological disease

The first study to investigate risk factors for the vascular condition called CCSVI (chronic cerebrospinal venous insufficiency) in volunteers without neurological disease has identified what the researchers call a remarkable similarity between this condition and possible or confirmed risk factors for multiple sclerosis.

ACGME approves Cedars-Sinai's neurology residency training program

The Accreditation Council for Graduate Medical Education has approved a neurology residency training program at Cedars-Sinai Medical Center. Recruitment of the first group of three residents is under way through the 2012 "match," a process in which an independent organization pairs applicants with programs to meet the preferences of each.

Physicians can do better if they learn from their failures

When seeking a physician, you should look for one with experience. Right? Maybe not. Research on physicians' decision-making processes has revealed that those who pay attention to failures as well as successes become more adept at selecting the correct treatment.

Alzheimer’s disease progression and body weight may be linked: Study

There have been studies that show that people who are overweight in middle age are more likely to develop Alzheimer's disease decades later than people at normal weight. However some studies also show that people in the earliest stages of Alzheimer's disease are more likely to have a lower body mass index (BMI).

Study examines link between early-stage Alzheimer's and lower BMI

Studies have shown that people who are overweight in middle age are more likely to develop Alzheimer's disease decades later than people at normal weight, yet researchers have also found that people in the earliest stages of Alzheimer's disease are more likely to have a lower body mass index (BMI). A current study examines this relationship between Alzheimer's disease and BMI.

Long-term AED therapy may increase risk of atherosclerosis in epilepsy patients

New research reveals that patients with epilepsy who were treated for extended periods with older generation antiepileptic drugs (AEDs) may be at increased risk for developing atherosclerosis, a common disorder known as hardening of the arteries.

Functional MRI illuminates brain networks activated by motion

An estimated 300,000 people in North America are afflicted with dystonia, a disorder characterized by a progressive loss of motor control. Patients with generalized dystonia grapple with involuntary muscle spasms that lead to uncontrolled twisting and turning in awkward, sometimes painful postures.

NYU Langone professor offers guidance on risk factors, interventions for SUDEP

Over time, epileptic seizures can lead to major health issues, including significant cognitive decline and even death, warns Orrin Devinsky, MD, professor, Departments of Neurology, Neurosurgery and Psychiatry at NYU Langone Medical Center.

PCMD researcher receives Alzheimer's Association grant to study dementia

The US-based Alzheimer's Association has awarded Dr. David Llewellyn of Peninsula College of Medicine and Dentistry (PCMD), University of Exeter, a prestigious two-year $100,000 New Investigator Research Grant to further his dementia research.

Study: Children with autism have more prefrontal brain neurons

In a small, preliminary study that included 13 male children, those with autism had an average 67 percent more prefrontal brain neurons and larger than average brain weight, than children without autism, according to a study in the Nov. 9 issue of JAMA.

Study reveals how default-mode network neurones interfere with our ability to pay attention

A study carried out by a team at the Centre de Recherche en Neurosciences de Lyon has just revealed how this network interferes with our ability to pay attention, by assessing the activity of the human brain's default-mode network neurones on a millisecond scale for the first time ever, in collaboration with Philippe Kahane's epilepsy department in Grenoble.

Hippocampus supports both recollection and familiarity memories

Human memory has historically defied precise scientific description, its biological functions broadly but imperfectly defined in psychological terms. In a pair of papers published in the November 2 issue of The Journal of Neuroscience, researchers at the University of California, San Diego report a new methodology that more deeply parses how and where certain types of memories are processed in the brain, and challenges earlier assumptions about the role of the hippocampus.

First rapid measurements of dopamine release in human brain

A research team led by investigators at the Virginia Tech Carilion Research Institute has demonstrated the first rapid measurements of dopamine release in a human brain and provided preliminary evidence that the neurotransmitter can be tracked in its movement between brain cells while a subject expresses decision-making behavior.

A glimpse into non-waking consciousness of lucid dreamers

When people dream that they are performing a particular action, a portion of the brain involved in the planning and execution of movement lights up with activity. The finding, made by scanning the brains of lucid dreamers while they slept, offers a glimpse into the non-waking consciousness and is a first step toward true "dream reading,".

Combination of available medical tests helps identify risk of AD

With age, forgetfulness and other signs of memory loss sometimes appear, prompting elderly individuals to seek a medical evaluation amid fears that they may be experiencing early symptoms of Alzheimer's disease (AD), the most common type of dementia among Americans aged 65 and older.

African-American or Hispanic children less likely to receive CT scans after head trauma

White children are far more likely to receive cranial computed tomography (CT) scans in an emergency department following minor head trauma than are African-American or Hispanic children, a study by researchers at UC Davis has found.

AiC: Health Research receives U.S. Army grant for neuroimaging studies of human performance

The Arlington Innovation Center: Health Research (AiC: Health Research), of Virginia Tech's National Capital Region, has been awarded a $1.5 million cooperative research and development agreement from the U.S. Army for neuroimaging studies of human performance.

Journal of Alzheimer's Disease supplement explores neuroimaging

Alzheimer's disease (AD) is a common problem that is becoming progressively burdensome throughout the world. A new supplement to the Journal of Alzheimer's Disease, Imaging the Alzheimer Brain, clearly shows that multiple imaging systems are now available to help understand, diagnose, and treat the disease.
