WEDNESDAY, Jan. 23, 2019 (HealthDay News) -- The most potent drug available for Parkinson's disease, levodopa, treats symptoms of the disease but does nothing to either ease or increase its still-mysterious underlying causes, a new clinical trial has concluded.
Doctors often delay prescribing levodopa, or L-dopa, to Parkinson's patients for fear that the drug might have toxic effects th...
WEDNESDAY, Jan. 23, 2019 (HealthDay News) -- Young adults with blood pressure that's higher than normal, but not yet high blood pressure, are still more likely to have brain shrinkage than those with normal blood pressure, a new German study finds.
It's long been thought that high blood pressure takes decades to affect the brain.
FRIDAY, Jan. 4, 2019 (HealthDay News) -- When a woman with epilepsy uses the anti-seizure drug valproate during a pregnancy, the odds that her baby will go on to develop ADHD rise, a new study suggests.
The Danish report can't prove that valproate causes attention-deficit/hyperactivity disorder (ADHD) in these cases, only that there's an association.
FRIDAY, Dec. 28, 2018 (HealthDay News) -- Some people who receive botulinum toxin injections for disorders that cause muscle tightness and contractions develop resistance to the treatment, researchers say.
The new study included nearly 600 patients with dystonia or spasticity who had been receiving botulinum toxin type A (commonly known as "Botox") for about three to five years.
WEDNESDAY, Dec. 26, 2018 (HealthDay News) -- You've probably seen movies where a veteran returns home from the horrors of war and wakes in the middle of the night yelling, punching or flailing so much that they harm themselves or a sleep partner.

But her foot continued to swell and ache, and even brushing it against the bedsheets produced excruciating pain. After five pu...
It was only a couple of weeks after Christian Bagge came home from the war in Iraq that the torment began. Lying in his hospital bed at Brooke Army Medical Center in San Antonio, Bagge suddenly felt a crushing pain in his feet. His feet, however, were not there. After the 23-year-old National Guard soldier's unit was hit by two bombs on an Iraqi road in June 2005, Bagge woke up in a military hospi...
What is Parkinson's disease?
We all lose brain cells as we age -- and most of them aren't really missed. But when the wrong cells stop doing their job, a person can become seriously ill.
Certain nerve cells, for example, have the vital job of producing dopamine, a compound that relays messages between parts of the brain that tells muscles how to move smoothly. People develop Parkinson's disease ...
There's still no cure for Alzheimer's or known way to prevent it. But if you're worried about developing the disease, your doctor just might give you an unexpected prescription. She might urge you to exercise daily, eat a diet rich in whole foods, and watch your weight. She might even recommend taking a language class or some dance lessons. Or having a fish dinner twice a week. Or adding curry dis...
