The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Leukoaraiosis modifies brain function in the elderly

Researchers at the Mayo Clinic say a common condition called leukoaraiosis, made up of tiny areas in the brain that have been deprived of oxygen and appear as bright white dots on MRI scans, is not a harmless part of the aging process, but rather a disease that alters brain function in the elderly.

Scientists discover why major depression or chronic stress can cause loss of brain mass

Major depression or chronic stress can cause the loss of brain volume, a condition that contributes to both emotional and cognitive impairment. Now a team of researchers led by Yale scientists has discovered one reason why this occurs - a single genetic switch that triggers loss of brain connections in humans and depression in animal models.

Scientists discover how pten gene causes brain changes that lead to autism-like behavior

Scientists affiliated with the UC Davis MIND Institute have discovered how a defective gene causes brain changes that lead to the atypical social behavior characteristic of autism. The research offers a potential target for drugs to treat the condition.

Reducing copper in the body delays onset of prion disease

Many of us are familiar with prion disease from its most startling and unusual incarnations-the outbreaks of "mad cow" disease (bovine spongiform encephalopathy) that created a crisis in the global beef industry. Or the strange story of Kuru, a fatal illness affecting a tribe in Papua New Guinea known for its cannibalism. Both are forms of prion disease, caused by the abnormal folding of a protein and resulting in progressive neurodegeneration and death.

Brain activity rapidly changes in olfactory regions following odor deprivation

Has a summer cold or mold allergy stuffed up your nose and dampened your sense of smell? We take it for granted that once our nostrils clear, our sniffers will dependably rebound and alert us to a lurking neighborhood skunk or a caramel corn shop ahead. That dependability is no accident. It turns out the brain is working overtime behind the scenes to make sure the sense of smell is just as sharp after the nose recovers.

Endocrine Society revises clinical practice guideline for management of thyroid dysfunction

The Endocrine Society has made revisions to its 2007 Clinical Practice Guideline (CPG) for management of thyroid disease during pregnancy and postpartum. The CPG provides recommendations for diagnosis and treatment of patients with thyroid-related medical issues just before and during pregnancy and in the postpartum interval.

Combination of novel drug therapy and PSA test can effectively detect prostate cancer

Researchers have successfully developed and tested a new prostate cancer screening method that uses the combined power of a novel drug therapy and changes in PSA levels over time to identify men with a high PSA who are more likely to have aggressive prostate cancer despite negative biopsies.

West Virginia University ICRC receives CDC grant to continue injury prevention research

The West Virginia University Injury Control Research Center (ICRC) has just been awarded a five-year grant totaling $4.1 million to continue as one of 11 such federally funded centers of excellence for injury prevention research, education and outreach in the nation, according to the funding agency, the Centers for Disease Control and Prevention (CDC).

Migraines not associated with cognitive decline

Migraines currently affect about 20 percent of the female population, and while these headaches are common, there are many unanswered questions surrounding this complex disease. Previous studies have linked this disorder to an increased risk of stroke and structural brain lesions, but it has remained unclear whether migraines had other negative consequences such as dementia or cognitive decline.

Effects on white matter brain volume from long-term alcoholism are different for men and women

(Boston) - Researchers from Boston University School of Medicine (BUSM) and Veterans Affairs (VA) Boston Healthcare System have demonstrated that the effects on white matter brain volume from long-term alcohol abuse are different for men and women. The study, which is published online in Alcoholism: Clinical and Experimental Research, also suggests that with abstinence, women recover their white matter brain volume more quickly than men.

Scientists take step toward developing blood test for Alzheimer's

The possibility of an inexpensive, convenient test for Alzheimer's disease has been on the horizon for several years, but previous research leads have been hard to duplicate.

Manipulating hormone-producing cells in the brain may help control blood sugar levels

Manipulating a group of hormone-producing cells in the brain can control blood sugar levels in the body - a discovery that has dramatic potential for research into weight-loss drugs and diabetes treatment.

Molecular missteps disrupt brain function in adult-onset muscular dystrophy

The molecular missteps that disrupt brain function in the most common form of adult-onset muscular dystrophy have been revealed in a new study published by Cell Press. Myotonic dystrophy is marked by progressive muscle wasting and weakness, as well as excessive daytime sleepiness, memory problems, and mental retardation.

Boys are little more susceptible to both bad and good exposures

A new study is the first to find a difference between how boys and girls respond to prenatal exposure to the insecticide chlorpyrifos. Researchers at the Columbia Center for Children's Environmental Health (CCCEH) at the Mailman School of Public Health found that, at age 7, boys had greater difficulty with working memory, a key component of IQ, than girls with similar exposures.

Trauma: spending more money doesn’t translate to higher survival rates

A large-scale review of national patient records reveals that although survival rates are the same, the cost of treating trauma patients in the western United States is 33 percent higher than the bill for treating similarly injured patients in the Northeast. Overall, treatment costs were lower in the Northeast than anywhere in the United States.
