If you take drugs to lower your blood pressure, your medication may also lower your risk of dementia, according to a new study released Monday by the American Academy of Neurology.
According to the study, people taking beta blockers, a class of drugs used to treat a number of conditions including high blood pressure, glaucoma and migraines, were less likely to have less cognitive impairment than those that did not. Beta blockers cause the heart to beat slower and with less force, which reduces blood pressure. They also open up blood vessels to increase blood flow.

A marker for later cognitive problems may be starting to show up in the brain tissue of former National Football League players.
According to a study published Monday in JAMA Neurology, researchers found that cognitive problems and depression are more common among aging NFL players with a history of concussion. But brain damage and mood problems among some segments of the NFL population is not stunning news anymore.
What has got scientists slightly giddy are those markers: Poor performance on cognitive tests also showing up on sophisticated brain scans. It suggests that damage post-concussion could some day be detectable by scanning the brain.

Scientists can't really know what a child is thinking, but they are interested in the brain processes that happen in educational settings. To that end, a new study in PLOS Biology compares the brains of children and adults, using "Sesame Street" as a way to test what happens on a neurological level during a popular TV program aimed at learning.
"We’re kind of honing in on what brain regions are important for real-world mathematics learning in children," said lead study author Jessica Cantlon, assistant professor of brain and cognitive sciences at the University of Rochester.

It's a heated question: should women take antidepressants during pregnancy? Some experts argue for it and some against, but a new study may ease the minds of women facing the decision.
Researchers say taking a common type of antidepressant does not increase the risk of having a stillborn child or losing an infant early in life. The study was published in this week's Journal of the American Medical Association (JAMA).
"It does strengthen the view that these meds are safer than we once thought," explains Dr. Jennifer Payne, director of the Women's Mood Disorders Center at Johns Hopkins School of Medicine in Baltimore. FULL POST

It's not the color, but what's inside that counts when it comes to medication. However, doctors suspect that's not exactly how patients see it.
According to a study published Monday in the medical journal Archives of Internal Medicine, changes in pill color significantly increase the odds that a patient will fail to take their medication as prescribed by their doctor.
First, the basics
Generic drugs are approved by the U.S. Food & Drug Administration’s Office of Generic Drugs. These off-brand alternatives must be “bioequivalent” to the brand-name version, meaning they must be identical in terms of dosage form, strength, route of administration, quality, intended use, and clinical efficacy. But the FDA does not require that the two versions look alike. FULL POST

The White House Office of National Drug Control Policy recently sent an alert to law enforcement, particularly along the Canadian border, warning them that Canada had approved non-abuse resistant generic versions of oxycodone, the active ingredient in OxyContin, Percocet and about 40 other painkillers.
"ONDCP expects companies will begin offering these generics without the abuse-resistant features in Canadian pharmacies within the next month," according to the alert.
The letter warned of the potential for these generics to show up here in the United States, where they are no longer available.

A study published in this week’s Pediatrics finds that infants who experienced oxygen deprivation in utero are at an increased risk of developing attention-deficit (hyperactivity) disorder in childhood.
Prenatal exposure to oxygen deprivation conditions, known as ischemic-hypoxic conditions, can result from birth asphyxia, neonatal respiratory distress syndrome and preeclampsia.
Researchers went through the medical records of nearly 82,000 children between the ages of 5 and 11 and found that children who had experienced those conditions were 16% more likely to be diagnosed with ADHD later in childhood. FULL POST

Do bad nutrition habits like overeating or binge eating lead to smoking pot? Some health experts think they might, according to a study published Monday.
Habits like overeating have always been known to affect our health, nutritionists say. In some cases, people say they lose control and just can’t stop. Now scientists are finding that both habits and that feeling of lacking control may lead to other health issues.
Researchers at Boston Children’s Hospital studied a group of 16,882 boys and girls between the ages of 9 and 15 who participated in the Growing Up Today Study, beginning in 1996. From that time to 2005, investigators sent out questionnaires every 12 to 24 months, asking if these children were overeating or binge eating. Binge eating was defined as eating an amount of food that is larger than most people would eat in the same time span under similar circumstances and feeling a lack of control over eating during that time. Overeating did not have to be connected to loss of control.

CNN recently published a three-day series on the experimental use of the drug Ecstasy as part of treatment for post-traumatic stress disorder. Readers had a lot to say in response to scientists who are studying the effects of MDMA, the chemical name for pure Ecstasy, on patients with PTSD.
Many readers said they were familiar with past research that’s been done on these drugs and questioned why they are still illegal.

It goes without saying that the human brain is complex, and would be hard to build from scratch. But researchers are looking to simulate how the brain works so that more human-like artificial intelligence can be created and we can better understand damage to our own brains.
Chris Eliasmith of the University of Waterloo in Ontario, Canada, led research published in the journal Science on a brain model called SPAUN - the Semantic Pointer Architecture Unified Network.
SPAUN lives inside a computer, can view images with a camera-like eye and can draw responses to questions. For example, show it the number "4" and it will write its own "4." It can even mimic the style of the numeral.
