1 in 5 Ontario students report serious brain injury: study

Posted: Published on June 26th, 2013

A new study shows 1 in 5 middle- and high-school students in Ontario report they have suffered at least one head injury that knocked them unconscious for more than five minutes or required overnight hospitalization. The studys authors say that suggests traumatic head injuries are far more common among young people than previous statistics indicated, likely because many incidents go unreported. The paper, published in the latest issue of the Journal of the American Medical Association, looks at the prevalence of such injuries among the provinces public school students in grades 7 through 12, as well as the circumstances surrounding them. Researchers at Torontos St. Michaels Hospital analyzed data from the Centre for Addiction and Mental Healths 2011 survey on drug use and health, which was filled out by close to 9,000 Ontario students aged 11 to 20. They found that roughly 5 per cent of students reported having a traumatic brain injury in the past year and more than half those cases (56 per cent) were sports-related. There was also a link with alcohol and cannabis, with frequent users showing significantly higher odds of a head injury in the past year than their tee-totalling peers. Boys were more likely … Continue reading →

Mild Brain Injuries Can Disable ADHD Kids

Posted: Published on June 26th, 2013

By Rick Nauert PhD Senior News Editor Reviewed by John M. Grohol, Psy.D. on June 26, 2013 Researchers have discovered that children with attention deficit hyperactivity disorder (ADHD) are more likely to demonstrate a moderate disability after sustaining a mild traumatic brain injury (TBI) than children without ADHD. As such, researchers suggest that perhaps children with ADHD should be steered away from engaging in sports or hobbies that carry increased risks of sustaining a TBI, and that children with ADHD receive special monitoring if a TBI occurs. Detailed findings of the study are phenomenon are reported and discussed in an article found in the Journal of Neurosurgery: Pediatrics. The researchers set out to find whether ADHD has an effect on outcome following mild traumatic brain injury (TBI). To do this, they examined the charts of all patients with ADHD who received a diagnosis of mild closed-head injury (an injury in which no neurosurgical treatment is required) at Childrens Hospital of Pittsburgh between January 2003 and December 2010. A mild closed-head injury results in what is termed a mild TBI, which is categorized by an initial Glasgow Coma Scale score of 13 to 15. From their review of patient charts, Dr. … Continue reading →

VEPS sensor detects signs of traumatic brain injury before it’s too late

Posted: Published on June 26th, 2013

Victims of penetrating head injuries usually seek immediate attention, as the hole in their skull is difficult to miss. However, people with closed-head injuries may show few immediate signs of the trauma, and appropriate diagnostic equipment (primarily a CAT scanner) is often not immediately available. A Mexican-US team of researchers has now developed a simple, easy to operate, and inexpensive electromagnetic sensor for traumatic brain injuries, suited to on site use by field personnel and paramedics. Traumatic brain injury (TBI) is a common feature of life around the world, causing some 60,000 deaths each year in the US alone. The primary causes of TBI include shootings, falls, and traffic accidents. Of additional concern has been the recent discovery of the long-term effects of mild but repeated TBI, usually in the form of concussions, in participants of sports such as football, hockey, and martial arts. Overall, about 20 percent of TBI lead to death within a month, with many others resulting in permanent brain dysfunction. Physicians believe many of these negative outcomes could be prevented by earlier diagnosis and treatment, ideally in the so-called "golden hour" immediately following the injury which offers the greatest chance of minimizing brain damage. Unfortunately, when … Continue reading →

Study of tropical fish reveals MS clues

Posted: Published on June 26th, 2013

An examination of the tiny, transparent zebrafish has shed light on how our nerve network protects itself, scientists said. They have discovered vital information about the way our bodies produce myelin, a fatty sheath that insulates and protects nerve fibres. The Edinburgh University team studied zebrafish because they share more than 80% of the genes associated with human diseases. The species has also been shown to respond to drugs in a similar way to humans. Their transparent bodies allows researchers to look directly into their nervous system without surgical or physical intervention. Myelin is critical for allowing nerve impulses to be transmitted quickly and affects our ability to walk, speak and see. The scientists found individual cells in the brain and central nervous system have only a matter of hours in which to generate this protective coating. They are now studying how the manipulation of genes and the use of drugs might promote myelin formation in zebrafish, potentially paving the way for the treatment of myelin-related conditions such as multiple sclerosis. The research is being published in the Developmental Cell journal. Contextual targeting label: Read more here: Study of tropical fish reveals MS clues … Continue reading →

Sneaky Delivery System Revolutionizes Multiple Sclerosis Treatment

Posted: Published on June 26th, 2013

By Maxx Chatsko | More Articles June 25, 2013 | Multiple sclerosis, or MS, is an autoimmune disorder in which the immune system attacks myelin surrounding nerves. It is a debilitating disease with no cure. Luckily, as our understanding of triggers in the immune system deepens, so does the likelihood of developing more effective treatments or even a cure. A new study shows just how far we have come. A team of scientists from Northwestern University, University Hospital Zurich in Switzerland, and University Medical Center Hamburg-Eppendorf in Germany demonstrated that resetting a patient's immune system was safe and reduced the targeting of myelin by 50%-75%. The phase 1 trial supported moving into a phase 2 trial in Switzerland after funds are raised. It is great news for patients and will likely revolutionize the way we treat autoimmune diseases and allergy medications. However, it will be a long time before it readily competes with Gilenya from Novartis (NYSE: NVS) . Fool contributor Maxx Chatsko breaks it down for investors in the following video. While you can certainly make huge gains in biotech and pharmaceuticals, the best investing approach is to choose great companies and stick with them for the long term. … Continue reading →

HRT, which is used to treat the symptoms of menopause, including hot flushes, has been previously linked with declining memory and a doubled risk of developing dementia. Researchers followed a group of more than 1,300 women between the ages of 50 and 55 who were on HRT medication called conjugated equine oestrogens (CEOs). The researchers, based at the Women's Health Centre of Excellence for Research at Wake Forest School of Medicine in Winston-Salem, North Carolina, gave one set of women placebos and one the HRT treatment, then studied the results after seven years.

HRT Not Linked To Cognitive Problems In Women 50 To 55

Posted: Published on June 26th, 2013

Editor's Choice Academic Journal Main Category: Menopause Also Included In: Women's Health / Gynecology Article Date: 26 Jun 2013 - 0:00 PDT Current ratings for: HRT Not Linked To Cognitive Problems In Women 50 To 55 The study showed that postmenopausal hormone therapy with conjugated equine estrogens (CEEs) is not linked to overall sustained benefit or risk to cognitive function in women of this age group. The therapy consists of a synthetic mixture of estrogen and is used to treat the symptoms of menopause, such as hot flashes and vaginal dryness. A previous report, the Women's Health Initiative Memory Study (WHIMS), found that women ages 65 and older taking postmenopausal hormone therapy with CEEs experienced deficits in global and domain-specific cognitive functioning. The authors explained that until now, it was not known whether the treatment had the same effect on younger women. Therefore, the new study, the Women's Health Initiative Memory Study of Younger Women (WHIMSY), analyzed whether younger postmenopausal women taking CEE-based hormone therapy resulted in longer-term influences on cognitive function. The team of experts, led by Mark A. Espeland, Ph.D., of the Wake Forest School of Medicine, Winston-Salem, N.C., presented the primary results from this investigation in JAMA … Continue reading →

Hormone replacement therapy not linked to memory woes in postmenopausal women

Posted: Published on June 26th, 2013

Women taking hormone replacement therapy (HRT) following menopause won't suffer memory problems or declines in their cognitive abilities, according to a new study. Researchers tracked more than 1,300 women who had been given hormone medications called conjugated equine estrogens (CEEs). The treatment consists of a synthetic mixture of estrogen, or female sex hormones, and is used to treat symptoms of menopause, including hot flashes and vaginal dryness. Hormone replacement therapy may also help stave off bone loss for older women. But, previous research of women over 65 has linked the medication to cognitive deficits like memory loss and a two-fold risk increase for dementia. For the new study, researchers randomized postmenopausal women between the ages of 50 and 55 to either receiving hormone therapy or placebo. After seven years, the researchers followed up with the women, and determined no overall differences in cognitive function scores between women taking the CEEs and the placebos. The research suggests giving the hormones at an earlier age of menopause may be more beneficial than prescribing them later. "Our findings provide reassurance that CEE-based therapies when administered to women earlier in the postmenopausal period do not seem to convey long-term adverse consequences for cognitive function," … Continue reading →

New study just adds to hormone replacement therapy debate

Posted: Published on June 26th, 2013

(CBS News) For the past decade, women who are post-menopausal have been getting conflicting information about hormone replacement therapy. Now, a new study in the Journal of the American Medical Association is adding to the debate. The study of 1,326 women taking synthetic hormones over seven years found no risk to cognitive functions for women 50-55, and some cognitive decline for women 65 and older. Dr. Sue Decotiis, a hormone replacement specialist at the New York University Langone Medical Center, said the study used products that are old. She explained, "With this study, they were using conjugated equine estrogens, and what that means is they get that from the urine of a horse. ... They were started to be used in the 1940s, and I'm certainly no longer using them in my practice." She said she's "not really" a fan of this study because they used something other than natural human estrogen known as beta estradiol. "They're not using the right product," she said. "It's sort of using the wrong key to get in your apartment. You're not going to get in. You're not going to get the right answers. We have to use the hormones that our body relates … Continue reading →
