Shire plc announced today the positive results of studies of the investigational medication guanfacine extended release (GXR, previously referred to as SPD503), a selective alpha-2A-adrenoceptor agonist. These data from two short-term phase III placebo-controlled studies and two long-term phase III open-label studies, presented at the 2007 American Psychiatric Association (APA) annual meeting, demonstrated that GXR significantly improved all core symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) in children aged 6 to 17 years.
You may not be able to relive your youth, but part of your brain can. Johns Hopkins researchers have found that newly made nerves in an adult brain's learning center experience a one-month period when they are just as active as the nerves in a developing child. The study, appearing this week in Neuron, suggests that new adult nerves have a deeper role than simply replacing dead ones.
Shire plc today announced that VYVANSE™ (lisdexamfetamine dimesylate) effectively controlled Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms in children aged 6 to 12 years. In addition, 95 percent of children taking VYVANSE daily for 12 months showed overall improvement, according to phase III open-label extension trial results. Further analysis of phase II clinical data demonstrated that VYVANSE provided consistent time to maximum concentration of d-amphetamine from patient to patient.
A popular stereotype that boys are better at mathematics than girls undermines girls' math performance because it causes worrying that erodes the mental resources needed for problem solving, new research at the University of Chicago shows.
The scholars found that the worrying undermines women's working memory. Working memory is a short-term memory system involved in the control, regulation and active maintenance of limited information needed immediately to deal with problems at hand.
Colonoscopies are considered the gold standard for detecting colon cancer, the second leading cause of cancer deaths in the United States. Research presented today at Digestive Disease Week® 2007 (DDW®) discusses contributing factors that could prevent patients from getting optimal results from their colonoscopy, including age of the patient, location of the screening and proper technician training. DDW is the largest international gathering of physicians and researchers in the fields of gastroenterology, hepatology, endoscopy and gastrointestinal surgery.
Score one for body language: It seems that body shape and the way people walk hold major cues to their attractiveness to others, according to collaborative research findings published by Texas A&M University professor Louis G. Tassinary and co-author Kerri Johnson of New York University.
"People have always tried to identify the magical formula for beauty, and we knew body shape was important, but we found movement was also key," Johnson says.
Researchers at the University of Warwick have found that sexual orientation has a real effect on how we perform mental tasks such as navigating with a map in a car but that old age does not discriminate on grounds of sexual orientation and withers all men’s minds alike.
In adults with major depressive disorder, adding aripiprazole to antidepressant therapy (ADT) resulted in significant improvement in the primary endpoint, the Montgomery-Asberg Depression Rating Scale (MADRS) Total Score.
In this six-week, randomized, placebo-controlled study atypical antipsychotic aripiprazole was added to antidepressants in patients who did not have an adequate response to ADT alone. (1)(Berman, 2007, APA Poster) These findings are from one of two completed studies evaluating adjunctive aripiprazole with ADT.
Imagine if a naturally occurring chemical in your body could help make you feel more calm and relaxed – but it would only work during the long days of summer.
The same chemical would, instead, make you aggressive and nasty when you were exposed to less daylight during the winter.
That's exactly what occurs for a specific species of mouse, according to a new study at Ohio State University.
It's a scenario straight out of Gray's Anatomy – a paramedic or doctor plops a mask over the face of a person struggling to breathe and begins dispensing pure oxygen.
Yet growing research suggests that inhaling straight oxygen can actually harm the brain. For the first time, a new UCLA brain-imaging study reveals why. The findings fly in the face of national guidelines for medical practice and recommend a new approach adding carbon dioxide to the gas mix to preserve brain function in patients.
In people with mild cognitive impairment, up to one drink of alcohol a day may slow their progression to dementia, according to a study published in the May 22, 2007, issue of Neurology®. Mild cognitive impairment is a transitional stage between normal aging and dementia that is used to classify people with mild memory or cognitive problems and no significant disability.
Researchers at Boston University School of Medicine (BUSM) and McLean Hospital have found that practicing yoga may elevate brain gamma-aminobutyric (GABA) levels, the brain's primary inhibitory neurotransmitter. The findings suggest that the practice of yoga be explored as a possible treatment for depression and anxiety, disorders associated with low GABA levels.
Capturing the coldest atoms in the universe within the confines of a laser beam, University of California, Berkeley, physicists have made a device that can map magnetic fields more precisely than ever before.
A new study in this month’s Journal of Personality and Social Psychology explains why NPR listeners always think they are right. When it comes to financial decisions or even concerns about terrorism, people are likely to be influenced by what others think but repeated exposure to one viewpoint can have almost as much influence as exposure to shared opinions from multiple people.
Hearing an opinion multiple times increases the recipient’s sense of familiarity and in some cases gives a listener a false sense that an opinion is more widespread then it actually is.
The ability to regenerate nerve cells in the body could reduce the effects of trauma and disease in a dramatic way. In two presentations at the NSTI Nanotech 2007 Conference, researchers describe the use of nanotechnology to enhance the regeneration of nerve cells. In the first method, developed at the University of Miami, researchers show how magnetic nanoparticles (MNPs) may be used to create mechanical tension that stimulates the growth and elongation of axons of the central nervous system neurons.
