Depression :: Clinical depression linked to abnormal emotional brain circuits

In what may be the first study to use brain imaging to look at the neural circuits involved in emotional control in patients with depression, researchers at the University of Wisconsin-Madison have found that brains of people with clinical depression react very differently than those of healthy people when trying to cope with negative situations.

Sleep :: Grandparents, older adults encouraged to seek help for a sleep disorder

September 9th is National Grandparents Day, a day to honor grandparents across America as important members of our families and communities. Grandparents play important roles in life, including that of guardian, comforter, and mentor.

Stress :: Self-test for stress and fatigue tested in undersea mission

An undersea mission simulating the space environment will provide data for development of tools to quickly assess stress, fatigue and cognitive fitness in preparation for performing critical mission tasks.

Menopause :: Grapes, Soy and Kudzu Blunt Some Menopausal Side Effects

Menopausal women are at relatively high risk for memory loss, high blood pressure (hypertension) and diabetes. A decade ago, the standard treatment for these problems was long-term hormone replacement therapy (HRT). Since then, studies have shown that extensive use of HRT is associated with significant adverse effects.

ADHD :: Gene predicts better outcome as cortex normalizes in teens with ADHD

Brain areas that control attention were thinnest in children with attention deficit hyperactivity disorder (ADHD) who carried a particular version of a gene in a study by the National Institutes of Health?s (NIH) National Institute of Mental Health (NIMH). However, the areas, on the right side of the brain?s outer mantle, or cortex, normalized in thickness during the teen years in these children, coinciding with clinical improvement. Although this particular gene version increased risk for ADHD, it also predicted better clinical outcomes and higher IQ than two other common versions of the same gene in youth with ADHD.

ADHD :: Gene variant is associated with brain anatomy, clinical course of ADHD

A variant of the dopamine receptor gene may be associated with attention-deficit/hyperactivity disorder (ADHD) and with thinner tissue in areas of the brain that handle attention, but also appears associated with better clinical outcomes among individuals with the disorder, according to a report in the August issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Coffee & caffeine may protect memory in older women

Drinking more than three cups of coffee (or the equivalent in tea) per day or caffeine may help older women protect their thinking skills, according to a study published in the August 7, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

Dementia :: In women, caffeine may protect memory, thinking skills

Caffeine may help older women protect their thinking skills, according to a study published in the August 7, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

Brain :: Human knowledge is based upon directed connectivity between brain areas

Which brain processes enable humans to rapidly access their personal knowledge? What happens if humans perceive either familiar or unfamiliar objects? The answer to these questions may lie in the direction of information flow transmitted between specialized brain areas that together establish a dynamic cortical network. This finding is reported in the latest issue of the scientific journal PLoS ONE published on Aug. 1, 2007.
