Scientists say they've identified 10 pesticides that kill neurons involved in Parkinson's disease, marking a leap forward in their understanding of the movement disorder.

Pesticide exposure has long been associated with Parkinson's, but investigators hadn't been able to pinpoint specific culprits.

A team from the University of California, Los Angeles and Harvard University pai...

Having higher blood sugar can lead to quicker loss of brain power after a stroke, a new study suggests.

High blood pressure and cholesterol were not associated with a similar mental loss, even in those at higher genetic risk for dementia.

“Having a stroke increases a person’s risk of dementia up to 50-fold, but we lack a comprehensive treatment approach that could reduce this ri...

Regular exercise has a long list of health benefits, and a new study suggests another one could be added: a lower risk of Parkinson's disease.

The study, of nearly 99,000 French women, found that those who were most physically active day to day were 25% less likely to develop Parkinson's ov...

When parents talk to their toddlers, they are not only teaching them words, but may be shaping their developing brains, too, a new study suggests.

Researchers found that toddlers whose parents spent a lot of time talking to them day to day showed a particular brain characteristic: a greater concentration of myelin in language-related parts of the brain.

Myelin is a protective layer ...

MONDAY, May 15, 2023 -- Researchers have discovered a genetic mutation that should actively protect people from Alzheimer's, thanks to a man belonging to a Colombian family known to be susceptible to the degenerative brain disease.

Based on his family's genetics, this unnamed patient should have started showing signs of Alzheimer's in his 40s.

“They start getting impaired at age 4...

Lightbulb inventor Thomas Edison believed a little shuteye could boost his creativity. Contemporary scientists think the iconic innovator was on to something.

But timing is key, they say.

“We found a strong effect of ‘sleep onset' on creativity,” said study author Kathleen Esfahany, an unde...

Poor sleep brought on by sleep apnea may ultimately undermine the brain health of older men and women, new research suggests.

The concern stems from a new brain scan investigation that involved 140 sleep apnea patients.

“Sleep apnea is a medical condition in which patients ... stop breathing during sleep, which can affect their sleep quality by causing multiple arousals and droppi...

Researchers have isolated for the first time a free-floating form of amyloid beta that appears to be a key driver of Alzheimer's disease.

Further, they argue that a newly approved Alzheimer's drug — lecanemab (Leqembi) — directly targets these small, complex chains of amyloid beta (A-beta) called fibrils. The U.S. Food and Drug Administration approved lecanemab in January.

The A...

For the first time, doctors have successfully performed fetal brain surgery to treat a rare blood vessel abnormality that can be fatal to newborns.

Experts said the accomplishment, for a condition known as a vein of Galen malformation (VOGM), is "exciting." But they also cautioned that this is one case, and more research is needed to know whether the prenatal brain procedure is a good str...

In trying to untangle the mysteries of long COVID, researchers have found anxiety and depression may play a role for some of those with the lingering condition.

In the study from researchers at University of California, Los Angeles (UCLA), patients who perceived that they had thinking difficulties during COVID infection were also more likely to have lingering physical symptoms than those...

Getting good sleep is an important part of wellness for many reasons, but new research suggests deep sleep may even guard against memory loss linked to Alzheimer's.

While disrupted sleep has been linked with accumulating beta-amyloid plaques in the brain faster, scientists found that superior amounts of deep, slow-wave sleep can be protective against memory decline in those with a high bu...

In U.S. states that provide financial assistance for low-income families, the difference is evident in children's brains, researchers report.

Their study found disparities in brain structure between children from high-income households compared to low-income households. However, the disparity was more than a third lower in states offering greater cash assistance to low-income families, c...

Near-death experiences — seeing a bright light, floating outside your body, watching your life flash past, communicating with lost loved ones — could well be part of a dying brain's final fight-or-flight response, a new report suggests.

Electroencephalogram (EEG) readings of dying intensive care unit patients found that some experienced a surge of brain activity in regions associated ...

A mind-reading device seems like science fiction, but researchers say they're firmly on the path to building one.

Using functional MRI (fMRI), a newly developed brain-computer interface can read a person's thoughts and translate them into full sentences, according to a report publish...

Scientists report that brain scans of long COVID patients show abnormal activity in areas related to memory.

The scan results validate the concerns of these patients, who feel like they're experiencing fatigue, trouble concentrating and memory issues, even though their scores on thinking tests don't show it.

“We were able to show that even though they were able to do the task -- t...

An extended-release version of a Parkinson's disease drug could provide more stable relief for patients with the movement disorder, new clinical trial data show.

The new formulation of levodopa, called IPX203, extended the duration of patients' “on time" — the amount of time the medication is working and symptoms are lessened, researchers reported this week at the American Academy of...

A significant number of patients take far longer to recover from a concussion than expected, and they may not be getting the care they need, according to a new study.

Researchers from the United Kingdom who studied concussion patients found that almost half had changes in how regions of the brain communicate with each other. This may cause long-term symptoms, including fatigue, and impair...

Maintaining tight control of your blood pressure could help your brain, potentially reducing your risk of stroke, a new study says.

When blood pressure was intensively managed in adults over age 50, patients had fewer lesions in the brain's white matter, according to researchers.

Having this consistently controlled blood pressure significantly reduced the risk of strok...

You had a rough day at work and got stuck in traffic on the way home, and suddenly your head starts pounding.

Stress headaches can be debilitating in the moment, but you don't have to suffer indefinitely.

If you're struggling with stress, you're not alone. More than one-quarter of adults in the United States reported they're too stressed ou...

Researchers have long tried to pinpoint a reason that some people have autism or autistic traits.

A new study from the United Kingdom builds upon evidence about one potential factor, finding that young children with ear, nose and throat problems were more commonly diagnosed with autism later.

This isn't to sa...

Comedian Richard Lewis is the latest celebrity to reveal that he has been diagnosed with the central nervous system disorder Parkinson's disease.

Lewis, 75, said in a
