Gaming Is Now an Extreme Sport

Gaming Is Now an Extreme Sport

Starting in the 1970’s, cult classics such as Pac-Man, Asteroids, and Pong helped pave the way for video games to become an increasingly popular form of entertainment. Encompassing a myriad of genres, video games provide many unique experiences, but who would have thought that they would legitimately become a competitive sport? Human beings by nature are competitive, yet we are also able to cooperate to accomplish some amazing feats.

Electronic Nerve-Stimulating Headband Approved by FDA to Prevent Migraines

Electronic Nerve-Stimulating Headband Approved by FDA to Prevent Migraines

The revolutionary product comes in the form of a battery-powered headband fitted with an electrode that sends an electrical signal through the skin to the trigeminal nerve, which plays a role in many migraines. By stimulating the nerve, the device was shown to help prevent migraines in a clinical test of 67 people who previously had at least 2 migraine attacks per month. The participants wore the device for 20 minutes a day for 3 months and recorded that they took significantly less migraine medication than those who received a placebo device. A satisfaction survey of more than 2000 people in Belgium and France also showed that 53% of patients said they were happy with the headband and that they would buy one for continued use.

Researchers Find Evidence That Brain Changes Can Result From Participation

Researchers Find Evidence Brain Changes Can Result From Participation in One Year of Contact

The impact of mild traumatic brain injury (mTBI), TBI, concussion and other head injuries associated with contact sports is a critical area of research within the field of neurosurgery. Today during the 82nd Annual Scientific Meeting of the American Association of Neurological Surgeons (AANS), researchers led by Alexander K. Powers, MD, presented the results of a study to determine the cumulative effects of head impacts as they relate to changes in the brain absent of concussion.

UCSF Launches Groundbreaking Online Registry to Drive Brain Disease Research

UCSF Launches Groundbreaking Online Registry to Drive Brain Disease Research

A new online project led by researchers at UC San Francisco promises to dramatically cut the time and cost of conducting clinical trials for brain diseases, while also helping scientists analyze and track the brain functions of thousands of volunteers over time.

With easy online registration, the Brain Health Registry is designed to create a ready pool of research subjects for studies on neurological diseases, such as Alzheimer’s and Parkinson’s, as well as depression, post-traumatic stress disorder and many other brain ailments. About one third of the cost of running a clinical trial comes from having to recruit patients, and many trials fail or are delayed because of it.

ER Doctors Commonly Miss More Strokes Among Women, Minorities and Younger Patients

ER Doctors Commonly Miss More Strokes Among Women, Minorities and Younger Patients

Analyzing federal health care data, a team of researchers led by a Johns Hopkins specialist concluded that doctors overlook or discount the early signs of potentially disabling strokes in tens of thousands of American each year, a large number of them visitors to emergency rooms complaining of dizziness or headaches.

The findings from the medical records review, reported online April 3 in the journal Diagnosis, show that women, minorities and people under the age of 45 who have these symptoms of stroke were significantly more likely to be misdiagnosed in the week prior to sustaining a debilitating stroke. Younger people in the study were nearly seven times more likely to be given an incorrect diagnosis and sent home without treatment despite such symptoms.

A New Approach to Huntington's Disease

A New Approach to Huntington’s Disease?

Tweaking a specific cell type’s ability to absorb potassium in the brain improved walking and prolonged survival in a mouse model of Huntington’s disease, reports a UCLA study published March 30 in the online edition of Nature Neuroscience. The discovery could point to new drug targets for treating the devastating disease, which strikes one in every 20,000 Americans.

Huntington’s disease is passed from parent to child through a mutation in the huntingtin gene. By killing brain cells called neurons, the progressive disorder gradually deprives patients of their ability to walk, speak, swallow, breathe and think clearly. No cure exists, and patients with aggressive cases can die in as little as 10 years.

Not All Medulloblastomas Are Alike

“Not All Medulloblastomas Alike”; Variations in Treatment Approaches Urged

Medulloblastoma, a rapidly growing brain tumor, can be categorized as four genetically and clinically distinct subtypes. Traditionally, increased extent of resection (EOR) has been linked to an improved prognosis in some medulloblastomas. A global team of more than 40 researchers at 20 institutions studied more than 500 medulloblastomas to determine the clinical importance of EOR and metastatic stage.

Migraine Attacks Increase Following Stress

Migraine Attacks Increase Following Stress “Let-Down”

Migraine sufferers who experienced reduced stress from one day to the next are at significantly increased risk of migraine onset on the subsequent day, according to a new study conducted by researchers at the Montefiore Headache Center and Albert Einstein College of Medicine at Yeshiva University. Stress has long been believed to be a common headache trigger. In this study, researchers found that relaxation following heightened stress was an even more significant trigger for migraine attacks. Findings may aid in recommending preventive treatments and behavioral interventions. The study was published online today in Neurology, the medical journal of the American Academy of Neurology.

Fregoli Syndrome

Murder, Intrigue, and a Case Involving Fregoli Syndrome?

On January 26, 1996, the Newtown, PA police and 3 SWAT teams surrounded the du Pont mansion on the Foxcatcher estate, about 15 miles west of Philadelphia. Earlier that day, John du Pont, the chemical company heir, shot and killed his longtime friend, Dave Schultz, 36, an Olympic gold medalist in freestyle wrestling. Armed with several guns, du Pont refused to surrender to police and held up in his mansion. A standoff commenced. It was particularly cold, and after 2 days, the police shut off the power and heat. When Mr. du Pont went outside to investigate, they captured him.

Hereditary Sensory and Autonomic Neuropathy Type I and Type II

Born Painless (HSAN II and III)

Unlike hereditary sensory and autonomic neuropathy type I (HSAN I), HSAN II and HSAN III are inherited in an autosomal recessive pattern. Both conditions are characterized by a deficit in distal sensory perception, with the lower limbs more severely affected than the upper limbs. Touch and temperature perception are affected to varying degrees in these individuals, with some depressed deep tendon reflexes. However, their ability to sense vibration may be normal. The extent of autonomic neuropathy and dysfunction varies greatly between types II and III. Type III is more severe, not only in sensory manifestations but also to the degree in which the autonomic system is affected.
