Canadian doctors who conducted the first robotic surgery to treat a brain aneurysm say the approach could boost the availability and precision of lifesaving stroke care.

Use of the technology could also be a first step toward remote robotic surgery for stroke and other conditions affecting brain blood vessels.

"In the future, perhaps, a patient could end up in a small center...

Ambulances outfitted as "mobile stroke treatment units" provide faster treatment and reduce patients' risk of severe disability and death, German researchers report.

The new study examined the use of three mobile stroke units in Berlin. Each unit is staffed with emergency medicine neurologists and has a CT scanner and lab on board that enables treatment at the scene.

Treatme...

For decades, artery-opening stents have helped prevent heart attacks, and new research suggests they might also help prevent strokes in the brain.

In a new study, the self-expanding, intracranial Wingspan brain stent seems effective over the long term in reducing stroke patients' risk of a subsequent stroke and death.

Intracranial stents are tiny mesh tubes that are permanen...

Love to cross-country ski? Well, all those days spent striding across the snow-covered wilderness may do more than keep you in great physical shape.

Swedish researchers report that very fit long-distance skiers were about 30% less likely to develop Parkinson's disease during their 20-year study.

The research suggests that any activity that keeps you fit might buffer the...

The so-called Mediterranean diet is already considered one of the healthiest for your heart, and now scientists say it may give your gut bacteria a boost, too.

The diet is typically high in fruits, vegetables, nuts, beans, olive oil and fish, and low in red meat and saturated fats. The new study finds that older adults who eat a Mediterranean diet tend to have more types of gut bacte...

Researchers who have pinpointed an antibody linked to life-threatening autoimmune disorders in children say their discovery could lead to faster diagnosis and treatment of these patients.

The investigators identified the myelin oligodendrocyte glycoprotein (MOG) antibody in their study of 535 children with central nervous system demyelinating disorders and encephalitis.

MOG ...

Adults with glioblastoma -- the most common and deadly type of brain tumor -- could survive more than twice as long if surgeons removed surrounding tissue as well as the tumor, a new study finds.

That involves cutting out "non-contrast-enhancing tumor" -- which doesn't light up on an MRI when a contrast agent is injected -- as well as contrast-enhancing tumor.

"Traditionally...

A genetic variant associated with Alzheimer's disease increases the risk of dementia in people with Parkinson's disease, researchers say.

The finding could lead to new treatments for dementia in Parkinson's patients, according to the team at Washington University School of Medicine in St. Louis.

Parkinson's disease is a progressive neurological disorder that causes tremors, ...

People afflicted with cluster headaches miss work twice as often as colleagues without the debilitating headaches, a new study finds.

Cluster headaches are extremely painful headaches that last from 15 minutes to three hours, for many days, or even weeks, in a row. They're more common in men.

For the study, Swedish researchers compared more than 3,200 working-age people who ...

People who develop Parkinson's disease at a younger age (before age 50) may have malfunctioning brain cells at birth, according to a study that also identified a drug that may help these patients.

At least 500,000 people in the United States are diagnosed with Parkinson's each year. Most are 60 or older at diagnosis, but about 10% are between 21 and 50.

Parkinson's is ...

A new discovery could lead to better treatments for multiple sclerosis (MS) and other autoimmune diseases, such as psoriasis and rheumatoid arthritis, researchers report.

MS occurs when immune cells get into the central nervous system (the brain and spinal cord), causing nerve damage that results in neurological problems. However, the cause is unclear.

Studies in a mouse mo...

Dementia patients may develop distinct speech and reading problems depending on their native language, a new study finds.

The study included 20 English-speaking and 18 Italian-speaking patients with primary progressive aphasia (PPA), a neurodegenerative disorder that affects language areas in the brain. It is often associated with dementia.

The patients had a type of PPA cha...

For people with the mysterious chronic pain condition fibromyalgia, researchers say nerve stimulation may offer some relief.

In a recent study, use of TENS -- transcutaneous electrical nerve stimulation -- during movement or activity was shown to significantly reduce pain associated with fibromyalgia after just four weeks.

Dr. Lesley Arnold, who was not involved with the n...

Surgical removal of the entire tumor may extend the lives of patients with a rare and deadly type of brain cancer called brainstem high-grade gliomas, a new study suggests.

Researchers analyzed data from 103 patients in the United States who had either a biopsy (15%) or had surgery to remove part or all of the tumor (85%) between 1973 and 2015. Of those who had surgery, about...

Some infants who appear healthy at birth after being exposed to the Zika virus in the womb develop neurological problems during their first year of life, a new study finds.

The study included pregnant women in Colombia who were exposed to Zika and had fetal MRIs and ultrasounds as their pregnancies progressed.

Of the 82 babies delivered by the women, 77 were born with no sig...

Poor sleep has been linked to the development of dementia and Alzheimer's disease, and now a new study suggests a possible reason why.

A small group of young, healthy men deprived of just one night of sleep had higher blood levels of tau protein than when they had a full and uninterrupted night of rest, researchers reported in a study published online Jan. 8 in Neurology.

...

For decades, scientists have known that Alzheimer's disease is accompanied by the buildup of clumps of amyloid protein between brain cells. Could these plaques be causing the disease?

That's been a prevailing theory driving Alzheimer's research for years. But a new study suggests the strategy could be wrong.

Researchers reporting Dec. 30 in the journal Neurology have...

In what doctors say is an extremely rare occurrence, a woman in her 70s went to her doctor to have impacted ear wax removed and wound up with permanent paralysis in her face.

The case report was described by British physicians in the Dec. 19 online edition of JAMA Otolaryngology--Head & Neck Surgery.

"A woman in her 70s presented to her general physician with imp...

Playing sports may improve the brain's ability to process sounds, a finding that could lead to new therapies for people who struggle with hearing, researchers report.

"No one would argue against the fact that sports lead to better physical fitness, but we don't always think of brain fitness and sports," said study senior author Nina Kraus. She's a professor of communication sciences a...

If you have a neurological disorder, a video chat with your doctor might be as good as an office visit for checking on your condition.

That's the conclusion of researchers who analyzed 101 studies on telemedicine use for concussion, traumatic brain injury, dementia, epilepsy, headache, multiple sclerosis, movement disorders, neuromuscular conditions and general neurology.

In...

The first generic versions of the multiple sclerosis drug Gilenya have been approved by the U.S. Food and Drug Administration.

"Approving safe and effective generics so patients have more treatment options continues to be a prio...

Three drugs used to treat severe seizures in epilepsy patients are equally effective, a new study finds.

The three medications -- levetiracetam (Keppra and Roweepra), fosphenytoin (Cerebyx) and valproate -- are commonly used to treat patients with "refractory status epilepticus." In these patients, severe seizures continue after treatment with benzodiazepine medications.

The...

Ultrasound may provide lasting relief from the involuntary muscle movements that are so debilitating to people with Parkinson's disease and another condition called "essential tremor," a small study concludes.

The treatment is still scarce, but it appears to deliver significant and lasting tremor relief, Italian researchers report.

It's called "focused ultrasound." Though ch...

Most of the time, Eva Wadzinski is a typical college student. Then suddenly, she isn't.

Wadzinski has epilepsy and has disruptive seizure clusters as often as 40 times a day.

They are not typical "Hollywood" seizures where people convulse (tonic-clonic seizures), making it harder for people to understand what she's going through. Instead, Wadzinski has a variety of what's ...

A treatment that delivers ultrasound waves to the brain may bring lasting relief to some people with debilitating hand tremors, a new study finds.

The study involved 76 patients with essential tremor -- a neurological condition that most often causes trembling in the hands during routine tasks like writing, eating and dressing. It can also affect the legs, head, trunk or voice.

...

Children with attention-deficit/hyperactivity disorder (ADHD) and low blood levels of omega-3 fatty acids might benefit from supplements, new research suggests.

Fish oil supplements appeared to boost attention in these kids, British researchers report.

The effect seemed limited to youngsters who weren't already getting enough omega-3 in their diets, however.

Prior ...

In a finding that might one day counter some of the damage of severe brain injury in humans, researchers report that embryonic neurons implanted in brain-injured mice helped resurrect memory and eased seizures.

"The idea to regrow neurons that die off after a brain injury is something that neuroscientists have been trying to do for a long time," said study leader Robert Hunt, an assi...

The deep stages of sleep may give the brain a chance to wash itself free of potentially toxic substances, a new study suggests.

Researchers found that during deep sleep, the "slow-wave" activity of nerve cells appears to make room for cerebral spinal fluid to rhythmically move in and out of the brain -- a process believed to rinse out metabolic waste products.

Those waste pr...

A new antibody test appears to have honed in on the most likely cause of a mysterious polio-like disease that regularly sweeps through the United States.

The new test detected antibodies for two types of enteroviruses in the spinal fluid of dozens of patients diagnosed with acute flaccid myelitis (AFM), a disease that causes potentially permanent and sometimes life-threatening paralys...

Former professional soccer players have a significantly increased risk of death from brain diseases such as Alzheimer's and Parkinson's, a new study finds.

"This analysis revealed that risk ranged from a fivefold...

Early treatment with an immune-boosting therapy might improve the outlook of young children with an advanced form of cancer, a new small study suggests.

The trial involved 43 children with high-risk neuroblastoma, a cancer that starts in immature nerve cells. Researchers found that a new treatment approach -- involving an experimental antibody given right off the bat -- started to qui...

Ringing in the ears (tinnitus) can make life miserable, but a brain implant may help, preliminary research suggests.

In a phase 1 trial of five patients whose severe tinnitus did not respond to other treatments, deep brain stimulation (DBS) diminished the ringing in four. The fifth patient received no relief, the researchers reported.

In DBS, electrodes are implanted in th...

Many pregnant women suffer from morning sickness early in pregnancy. But a new study suggests that a small minority who suffer a more severe form of the illness may be at higher odds of having a child with autism.

The form of morning sickness in question is called hyperemesis gravidarum, and it occurs in less than 5% of pregnancies, explained a team at Kaiser Permanente Southern C...

Lowering the body temperature in patients resuscitated from cardiac arrest helps a broader group of people than previously believed, a new French study finds.

For cardiac arrest patients with what's called a "nonshockable" rhythm, cooling the body almost doubles the odds they'll have good brain function if they survive, researchers have found.

A nonshockable rhythm means the...

Chronic migraine headaches plagued Adam Pressley from childhood, and by his 30s they had become a near-daily occurrence.

Pressley, 31, had tried everything to stop them: blood pressure drugs, antidepressants, seizure medications, and even quarterly injections of Botox.

Then his doctor suggested something surprising, saying plastic surgery could potentially relieve nerve pres...

Ten years after radiation treatment for head and neck cancer, some patients may develop problems speaking and swallowing, a new study finds.

These problems are related to radiation damage to the cranial nerves, the researchers explained. The condition is called radiation-induced cranial neuropathy.

"We had always thought that radiation did not damage cranial nerves because t...

People who suffer bouts of vertigo and dizziness may be suffering from a type of migraine for which treatments rarely work.

But a new, preliminary study of 18 such patients found that stimulating the vagus nerve in the neck can help relieve vertigo.

"Vestibular migraine can occur with or without headache. It's an uncomfortable feeling, an abnormal sense of motion. A lot of p...

For people at risk of Alzheimer's disease, working out a couple of times a week might at least slow the onset of the illness, new research suggests.

Regular exercise over a year slowed the degeneration of the part of the brain tied to memory among people who had a buildup of amyloid beta protein in their brain. These protein "plaques" are a hallmark of Alzheimer's, noted researchers a...

If you're looking for incentives to hit the gym, new research suggests that staying in good shape may help preserve brain structure, boost memory, and improve the ability to think clearly and quickly.

The finding follows an analysis of fitness and brain health among more than 1,200 young adults, average age 30. All underwent brain scans; tests to measure memory, sharpness, judgment an...

Variations in brain activity when a person is idle may affect their decisions about risky behavior, according to a new study.

The findings may help explain why people are inconsistent -- and sometimes irrational -- and could lead to new treatments for gambling addiction, the researchers said.

"Experts have long struggled to explain why people are so erratic, making one decis...

If you use your feet like hands from birth, the brain will create a different "map" of the toes that's more like the one it has for the fingers, new research reveals.

That's the case with Tom Yendell and Peter Longstaff, two foot artists in the United Kingdom who were born with no hands and paint with their feet.

Researchers compared functional MRI images of their brains to...

After losing a lower leg, Savo Panic received a prosthetic limb that helped restore movement. But prostheses are imperfect, and he suffered tremendous "phantom" leg pain.

Now, European scientists say they've developed a technology that restores natural feeling and improves walking in patients who've had a lower leg amputation. The approach also eliminated phantom pain in Panic and red...

People with restless legs syndrome (RLS) have nearly three times the risk of suicide and self-harm, which indicates that there may be a link between the physical condition and mental health.

In a new study, Penn State researchers analyzed data on more than 24,000 people with RLS and about 145,000 people without the neurological condition. None had a history of suicide attempts or self...

It's bad enough to have an aching head, but about one in 10 people who suffer from headaches also experience facial pain, researchers have found.

The study included more than 2,900 people with primary headaches. These are ones not caused by another condition and they include migraine and cluster headaches. Participants completed questionnaires about their headaches and any facial pain...

New research is untangling the complex relationship between symptoms of depression and losses in memory and thinking that often emerge together with Alzheimer's disease.

In fact, the new data suggests that "depression symptoms themselves may be among the early changes in the preclinical stages of dementia syndromes," explained study lead author Dr. Jennifer Gatchel. She works in the d...

Binge-watching episodes of your favorite shows does no favors for your brain, an expert warns.

"It's important to recognize that the brain is not an isolated organ -- it responds to its environment," said Dr. Randall Wright, a neurologist at Houston Methodist in Texas. "When we binge-watch, we create an unhealthy environment for the brain because we're sitting for long periods of time...

There have been 118 more reports of e-cigarette users suffering seizures since the U.S. Food and Drug Administration first warned the public about the danger in April.

That brings the total number of reported cases to 127 between 2010 and 2019, the agency said Wednesday.

However, the additional cases don't necessarily indicate a rise in the rate or number of such incidents, ...

If you have migraines, one or two cups of coffee a day may be okay, but three or more could raise your risk of an attack, a new study concludes.

"Interestingly, despite some patients with episodic migraine thinking they need to avoid caffeine, we found that drinking one to two servings/day was not associated with higher risk of headache," said study principal investigator Dr. Suzanne...

A small electric "tickle" to the ear may affect the body's nervous system, and British researchers claim this can promote overall well-being and may potentially slow down some effects of aging.

The tickle treatment is called transcutaneous vagus nerve stimulation (tVNS). The procedure involves placing custom-made clips containing electrodes on the part of your ear called the tragus; ...

Folks who get treatment from a stem cell clinic could be spending their money on what amounts to snake oil, a new study warns.

Doctors administering stem cells might have no expertise in the condition they're trying to treat, and the cells themselves might be derived from questionable or discredited sources -- if the treatment contains any stem cells at all.

"The stem cell treat...
