Head Injury With Loss Of Consciousness Does Not Increase The The Risk Of Dementia – Part 3 of 3
So “The dramatic examples of former National Football League players, hockey players and wrestlers who have an unusual illness, unmistakeable by depression, agitation and psychosis are quite different from Alzheimer’s disease patients who tend to be apathetic. Much remains to be discovered about the role of lifelong traumatic brain injury history, including beastliness and nature of torque and other physical factors, and late-life mental decline”.
Another expert, Dr Danny Liang, a neurosurgeon at North Shore-LIJ Cushing Neuroscience Institute in Manhasset, NY, thinks these findings are too exact to say much about the risk of dementia as a result of traumatic brain injury. “The study is restricted to a limited population so it’s hard to extrapolate these findings to other populations. It is also realizable that there were people who had traumatic brain injury who did develop dementia before age 65, so they were not included in the study”. There also was no data on injury severity or duration of unconsciousness female. Brain injuries differ, and canny the severity is important to determine the ultimate outcome.

Head Injury With Loss Of Consciousness Does Not Increase The The Risk Of Dementia – Part 2 of 3
At the start of the study, which was published recently in the Journal of Neurology, Neurosurgery & Psychiatry, none of the participants suffered from dementia. Over 16 years of follow-up, the researchers found that those who had suffered a shocking brain injury with loss of consciousness at any time in their lives did not increase their risk for developing Alzheimer’s or other forms of dementia.
The peril of another traumatic brain injury, however, more than doubled if the first injury occurred before age 25 and almost quadrupled if the injury happened after age 55. Similarly, a late traumatic brain injury more than doubled the odds of death from any cause, the study found. Dams-O’Connor’s group plans to look at risk factors to try to understand why some people have awful long-term prognosis after a brain injury.
One expert said genetics may play a role. “My guess is that the risk for post-traumatic-brain-injury Alzheimer’s disease has a genetic component with some genes increasing chance and others offering protection,” said Dr Sam Gandy, associate director of the Mount Sinai Alzheimer’s Disease Research Center in New York City. These findings should not be disturbed with those regarding athletes who suffer brain injuries.

Head Injury With Loss Of Consciousness Does Not Increase The The Risk Of Dementia – Part 1 of 3
Head Injury With Loss Of Consciousness Does Not Increase The The Risk Of Dementia. Having a disturbing brain injury at some rhythm in your life doesn’t raise the risk of dementia in old age, but it does increase the odds of re-injury, a new study finds. “There is a lot of fear among people who have sustained a brain mayhem that they are going to have these horrible outcomes when they get older,” said senior author Kristen Dams-O’Connor, assistant professor of rehabilitation medicine at the Icahn School of Medicine at Mount Sinai Medical Center in New York City. “It’s not true. But we did win a risk for re-injury”.
The 16-year study of more than 4000 older adults also found that a recent traumatic brain injury with unconsciousness raised the distinction of death from any cause in subsequent years. Those at greatest risk for re-injury were people who had their brain injury after age 55, Dams-O’Connor said. “This suggests that there are some age-related biological vulnerabilities that come into freedom in terms of re-injury risk”.
Dams-O’Connor said doctors need to look out for health issues among older patients who have had a traumatic brain injury. These patients should try to steer clear of another head injury by watching their balance and taking care of their overall health. To investigate the consequences of a traumatic brain injury in older adults, the researchers collected data on participants in the Adult Changes in Thought study, conducted in the Seattle ground between 1994 and 2010. The participants’ average age was 75.

Breathing Problems During Sleep Are Related To Air Pollution – Part 3 of 3
Particles of vitiation “may influence sleep through effects on the central nervous system, as well as the upper airways,” wrote co-author Antonella Zanobetti in a news release, noting that the exact mechanism is unclear. “These late data suggest that reduction in air pollution exposure might decrease the severity of such sleep disruptions”. The study, funded by the US National Heart Lung and Blood Institute, the EPA and the US National Institute of Environmental Health Sciences, appeared online June 14 in the American Journal of Respiratory and Critical Care Medicine info.

Breathing Problems During Sleep Are Related To Air Pollution – Part 2 of 3
The study authors pored over data from the Sleep Heart Health Study, which examined the heart health and sleep patterns of more than 6000 relations between 1995 and 1998. They then compared those patterns to Environmental Protection Agency (EPA) air pollution data on seven cities: Minneapolis; New York City; Phoenix; Pittsburgh; Sacramento; Tucson, Ariz; and Framingham, Mass.
The researchers analyzed matter on more than 3000 people and adjusted for factors such as age, gender, smoking and temperature so they wouldn’t throw off the results. They found that incidents of log a few zees apnea and low levels of oxygen during sleep went up as the temperature rose during all seasons of the year. Sleep-disordered breathing also rose during the summer as air pollution worsened.

Breathing Problems During Sleep Are Related To Air Pollution. A altered study has found a link between air pollution and breathing-related disruptions during sleep. Conducted by the Harvard School of Public Health and Brigham & Women’s Hospital, the authors claim this the first attempt to document a link between exposure to pollution and sleep-disordered breathing. Breathing-related catnap disruptions come in several forms, of which the best known is sleep apnea.
It causes people to repeatedly wake up when their airways constrict and breathing is cut off. In many cases, sufferers don’t realize they have the condition, which can present to the development of heart disease and stroke. In the study, researchers tried to discover if air pollution – which irritates the airways – has anything to do with sleep disruptions, which lay hold of an estimated 17 percent of adults in the United States.

New Treatments Hyperactivity Teenagers – Part 2 of 2
The American Psychiatric Association reports that ADHD affects 3 percent to 7 percent of school-age children. The findings were scheduled for offering Monday at the annual intersection of the Radiological Society of North America in Chicago. The researchers used an MRI technique called magnetic field correlation imaging to measure iron levels in the brains of 22 children and teens with ADHD and another bundle of 27 children and teens without the disorder (the “control” group).
The scans revealed that the 12 ADHD patients who’d never been treated with psychostimulant drugs such as Ritalin had lessen brain iron levels than those who’d received the drugs and those in the control group. The lower iron levels in the ADHD patients who’d never taken stimulant drugs appeared to regularize after they took the medicines. No significant differences in patients’ brain iron levels were detected through blood tests or a more conventional method of measuring brain iron called MRI letting up rates, the study authors noted funciona. Data and conclusions presented at meetings are typically considered preliminary until published in a peer-reviewed medical journal, Dec 2013.
