New research is suggesting links between street lights, neon signs and other forms of nighttime outside lighting and sleeplessness and mood disorders among teens.
The study of more than 10,000 American kids aged 13 to 18 couldn't prove cause and effect. However, it found that teens living in areas with high levels of artificial outdoor light at night went to bed about 29 minutes later...
It's a virus some might not even remember, but babies born to mothers infected with Zika who appeared normal at birth still experienced neurological or developmental problems, new research suggests.
A hallmark of infection with the mosquito-borne Zika virus in pregnant women is delivering a baby with an abnormally small head -- a condition called microcephaly. But as children exposed ...
TUESDAY, July 7, 2020 (HealthDay News) -- Deep sleep is essential for good health, and too little of it may shorten your life, a new study suggests.
REM (rapid eye movement) sleep is when dreams occur and the body repairs itself from the ravages of the day. For every 5% reduction in REM sleep, mortality rates increase 13% to 17% among older and middle-aged adults, resear...
Data from a five-year clinical trial is adding to growing evidence that deep brain stimulation (DBS) can slow the ravages of Parkinson's disease.
Researchers at Vanderbilt University Medical Center in Nashville, Tenn., said that the therapy appears to curb any worsening of tremor and other symptoms, as well as lessening a patient's need for medications.
"Parkinson's is relen...
For those who try to catch up on lost sleep during the weekend, French researchers have some bad news: Once Saturday and Sunday have come and gone, many will find they're still seriously short on sleep.
The finding centered on adults who regularly get only six hours of sleep or less on weekdays. That's far less than the seven to eight hours per night that most people need, said study ...
Love a glass of wine with dinner? There's good news for you from a study that finds "moderate" alcohol consumption -- a glass or two per day -- might actually preserve your memory and thinking skills.
This held true for both men and women, the researchers said.

In findings that could pave the way to a new treatment for Parkinson's disease, scientists have figured out how to spur the production of new brain cells in mice.
The advance centers on a protein found in various cells in mice and humans. Researchers found that blocking it in the mouse brain caused certain "support cells" there to transform into specialized neurons that produce the ch...
Can working or playing in the hot sun "fry" your brain?
Yes, claims a new, small study that found too much heat on the head hampered thinking in volunteers.
Most people know that high temperatures can cause heat exhaustion or heat stroke as the body's core temperature becomes dangerously high, but the beating sun can affect your brain even if your body temperature stays norm...
It often seems the older a person gets, the less they sleep, but new research suggests that inconsistent sleep patterns might predict a future diagnosis of Parkinson's disease.
Researchers who studied 2,930 older men for more than a decade found that those with a particular sleep problem -- called circadian rhythm disruptions -- were three times more likely to develop Parkinson's dise...
Stroke patients in rural areas of the United States are less likely to get cutting-edge treatments and more likely to die than those in cities.
That's the takeaway from a new analysis of nationwide data on more than 790,000 adults who were hospitalized with stroke between 2012 and 2017. Most were 64 or older.
Compared to patients in cities, those treated at rural hospitals w...
While a fever and cough have seemed to be the early warning signs of COVID-19, new research shows almost half of hospitalized patients experience a host of neurological problems.
In fact, headaches, dizziness, strokes, weakness, decreased alertness or other neurological symptoms can appear before the more commonly known symptoms of infection with the new coronavirus (known as S...
Researchers may have gained new insights into a mystifying condition that causes children's behavior to change so severely and abruptly, it can be like they woke up as a different person.
The condition is known as pediatric acute-onset neuropsychiatric syndrome, or PANS. It is diagnosed when a child has a dramatic -- sometimes overnight -- onset of psychiatric and neurological symptom...
Amid recent warnings about a possible link between COVID-19 in children and an inflammatory condition called Kawasaki disease that can harm the heart and other organs, heart experts stress that such cases seem to be rare.
Most kids with COVID-19 have mild symptoms or none at all, but a small number have developed Kawasaki disease, often requiring hospitalization and occasionally, inte...
Studies are beginning to show that, in rare cases, people with severe COVID-19 may develop the serious nervous system disorder known as Guillain-Barre syndrome.
"Guillain-Barre syndrome is a well-known condition in which one's immune system targets peripheral nerves as foreign and attacks them, resulting in the cardinal features of the disease," explained Dr. Anthony Geraci, who direc...
Even before symptoms develop, the brains of people with early Alzheimer's disease have high levels of amyloid protein plaques, a new study reveals.
Those levels in older adults with no dementia symptoms are associated with a family history of disease, lower scores on thinking/memory tests, and declines in daily mental function.
The first findings from the so-called A4 study ...
A study out of China finds that strokes, altered consciousness and other neurological issues are relatively common in more serious cases of COVID-19.
