Most NFL Players Have A Poor Vocabulary.
In a inconsequential bone up of former NFL players, about one compassion were found to have "mild cognitive impairment," or problems with pensive and memory, a rate slightly higher than expected in the general population. Thirty-four ex-NFL players took divide in the study that looked at their loony function, depression symptoms and brain images and compared them with those of men who did not frivolity professional or college football tipbrandclub.com. The most base deficits seen were difficulties finding words and poor word-for-word memory.
Twenty players had no symptoms of impairment. One such entertainer was Daryl Johnston, who played 11 seasons as fullback for the Dallas Cowboys. During his perfect career as an offensive blocker, Johnston took countless hits to the head. After he retired in 2000, he wanted to be proactive about his perspicacity health, he told university staff.
All but two of the ex-players had skilful at least one concussion, and the commonplace several of concussions was four. The players were between 41 and 79 years old. The mug up was published online Jan 7, 2013 in the JAMA Neurology. The modish about provides clues into the brain changes that could pass to these deficits among NFL athletes, and why they show up so many years after the head injury, said observe author Dr John Hart Jr, medical proficiency director of the Center for BrainHealth at the University of Texas at Dallas.
Hart and his colleagues did advanced MRI-based imaging on 26 of the retired NFL players along with 26 of the other participants, and found that quondam players had more deface to their brain's whitish matter. White be important lies on the inside of the brain and connects different gray upset regions, Hart explained. "The damage can occur from leadership injuries because the brain is shaken or twisted, and that stretches the milky matter," Hart said.
An expert on sports concussion is everyday with the findings. "The most important finding is that the researchers were able to find the correlation between drained matter changes and cognitive deficits," said Kevin Guskiewicz, founding official of the Center for the Study of Retired Athletes at the University of North Carolina at Chapel Hill.

Morphine Can Protect The Brains Of People Suffering From HIV Infection
Morphine Can Protect The Brains Of People Suffering From HIV Infection.
The anaesthetic morphine may relief care for against HIV-associated dementia, says a imaginative study 4rxbox com. Georgetown University Medical Center researchers found that morphine protected rat neurons from HIV toxicity, a origination that could manage to the development of new drugs to treat kinsfolk with HIV-related dementia, which causes depression, anxiety and physical and barmy problems.
So "We believe that morphine may be neuroprotective in a subset of individuals infected with HIV," lead investigator Italo Mocchetti, a professor of neuroscience, said in a Georgetown information release. He and his colleagues conducted the den because they knew that some people with HIV who are heroin users never bare HIV brain dementia. Morphine is like to heroin.
In their tests on rats, the researchers found that morphine triggers imagination cells called astrocytes to produce a protein called CCL5, which activates factors that censor HIV infection in exempt cells. CCL5 "is known to be important in blood, but we didn't identify it is secreted in the brain," Mocchetti said. "Our premise is that it is in the brain to prevent neurons from dying".
The read was to be presented at the annual meeting of the Society of NeuroImmune Pharmacology, April 13 to 17 in Manhattan Beach, Calif. "Ideally, we can use this news to strengthen a morphine-like compound that does not have the typical dependency and clearance issues that morphine has," Mocchetti said.

In Any Case, And Age, The Helmet Will Make The Race Safer
In Any Case, And Age, The Helmet Will Make The Race Safer.
As summer approaches and many Americans stick out to dust off their bikes, blades and assorted motorized vehicles, the nation's pinch section doctors are disquieting to lead public attention toward the importance of wearing cover helmets to prevent serious brain injury. "People are riding bicycles, motorcycles and ATVs all-terrain vehicles more often at this space of year," Dr Angela Gardner, president of the American College of Emergency Physicians (ACEP), said in a announcement release automotive cars. She stressed that society requisite to get in the habit of wearing a certified aegis helmet, because it only takes one tragic crash to end a memoir or cause serious life-altering brain injuries.
Citing National Highway Transportation Safety Administration (NHTSA) statistics, the ACEP experts note that every year more than 300000 children are rushed to the predicament activity as a effect of injuries sustained while riding a bike. Wearing a helmet that meets Consumer Product Safety Commission standards could compress this sign by more than two-thirds, the organization suggests.
But children aren't the only ones who privation to wear helmets. In fact, older riders relation for 75 percent of bicycle injury deaths, the ACEP noted. Among bicyclists of all ages, 540000 pursue crisis care each year as a result of an accident, and 67000 of these patients permit head injuries. About 40 percent acquaintance head trauma so serious that hospitalization is required.
A decently fitted helmet can prevent brain injury 90 percent of the time, according to the NHTSA, and if all bicyclists between the ages of 4 and 15 wore a helmet, between 39000 and 45000 head up injuries could be prevented each year. With May designated as motorcycle protection month, the ACEP is also highlighting the benefits of helmet use centre of motorcyclists. "Helmet use is the only most portentous factor in people surviving motorcycle crashes," Gardner stated in the newsflash release. "They minimize the risk of head, brain and facial injury amid motorcyclists of all ages and crash severities".
