Most NFL Players Have A Poor Vocabulary

Most NFL Players Have A Poor Vocabulary.
In a teeny survey of former NFL players, about one quarter were found to have "mild cognitive impairment," or problems with meditative and memory, a rate slightly higher than expected in the general population. Thirty-four ex-NFL players took her in the study that looked at their mental function, depression symptoms and brain images and compared them with those of men who did not challenge professional or college football. The most common deficits seen were difficulties pronouncement words and poor verbal memory.

Twenty players had no symptoms of impairment. One such jock was Daryl Johnston, who played 11 seasons as fullback for the Dallas Cowboys. During his proficient career as an offensive blocker, Johnston took countless hits to the head. After he retired in 2000, he wanted to be proactive about his wit health, he told university staff.

All but two of the ex-players had master at least one concussion, and the average number of concussions was four. The players were between 41 and 79 years old. The ponder was published online Jan 7, 2013 in the JAMA Neurology. The flow study provides clues into the brain changes that could diva to these deficits among NFL athletes, and why they show up so many years after the head injury, said study inventor Dr John Hart Jr, medical science 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 departed players had more impair to their brain's white matter. White trouble lies on the inside of the brain and connects different gray matter regions. "The hurt can occur from head injuries because the brain is shaken or twisted, and that stretches the white matter".

An wonderful on sports concussion is familiar with the findings. "The most important finding is that the researchers were able to find the correlation between ivory matter changes and cognitive deficits," said Kevin Guskiewicz, founding the man of the Center for the Study of Retired Athletes at the University of North Carolina at Chapel Hill.

Girls Mature Faster Than Boys

Girls Mature Faster Than Boys.
New acumen research suggests one ground girls mature faster than boys during their teen years. As people age, their brains reorganize and mark down connections. In this study, scientists examined brain scans from 121 thriving people, aged 4 to 40. It's during this period that the major changes in capacity connectivity occur. The researchers discovered that although the overall number of connections is reduced, the intelligence preserves long-distance connections important for integrating information.

The findings might explain why brain act the part of doesn't decline - but instead improves - during this period of connection pruning, according to the check in team. The researchers also found that these changes in brain connections begin at an earlier age in girls than in boys. "Long-distance connections are grim to establish and maintain but are crucial for fast and efficient processing," said sanctum co-leader Marcus Kaiser, of Newcastle University, in England.

Scientists Are Researching The Causes Of The Inability To Read

Scientists Are Researching The Causes Of The Inability To Read.
Glitches in the connections between unfailing acumen areas may be at the root of the common learning hubbub dyslexia, a new study suggests. It's estimated that up to 15 percent of the US citizens has dyslexia, which impairs people's ability to read. While it has long been considered a brain-based disorder, scientists have not conceded exactly what the issue is.

The new findings, reported in the Dec 6, 2013 circulation of Science, suggest the blame lies in faulty connections between the brain's storage spell for speech sounds and the brain regions that process language. The results were surprising, said be conducive to researcher Bart Boets, because his team expected to find a different problem. For more than 40 years many scientists have meditation that dyslexia involves defects in the brain's "phonetic representations" - which refers to how the central sounds of your native language are categorized in the brain.

But using sensitive perception imaging techniques, Boets and colleagues found that was not the case in 23 dyslexic adults they studied. The phonetic representations in their brains were just as "intact" as those of 22 adults with regular reading skills. Instead, it seemed that in citizenry with dyslexia, language-processing areas of the brain had difficulty accessing those phonetic representations. "A apt metaphor might be the comparison with a computer network," said Boets, of the Leuven Autism Research Consortium in Belgium.

And "We show that the data - the data - on the server itself is intact, but the correlation to access this information is too slow or degraded". And what does that all mean? It's too soon to tell, said Boets. First of all this studio used one form of brain imaging to study a small conglomeration of adult university students. But dyslexia normally begins in childhood.

Useless The Second Phase Of The Definition Of Brain Death

Useless The Second Phase Of The Definition Of Brain Death.
Making families time for a second-best exam to confirm a brain death diagnosis is not only supererogatory but may make it less likely that the family will agree to donate their loved one's organs, a unexplored study finds. Researchers reviewed records from the New York Organ Donor Network database of 1,229 adults and 82 children who had been declared cognition dead. All of the ancestors had died in New York hospitals over a 19-month period between June 2007 and December 2009.

Patients had to lacuna an average of nearly 20 hours between the first and second exam, even though the New York State Health Department recommends a six-hour wait, according to the study. Not only did the tick exam continue nothing to the diagnosis - not one patient was found to have regained brain function between the first and the second exam - verbose waiting times appeared to make families more reluctant to give consent for organ donation. About 23 percent of families refused to grant their loved ones organs, a include that rose to 36 percent when wait times stretched to more than 40 hours, the investigators found.

The gossip was also true: Consent for organ donation decreased from 57 percent to 45 percent as hold on times were dragged out. Though the research did not look at the causes of the refusal, for families, waiting around for a next exam means another emotionally exhausting, stressful and uncertain day waiting in an exhaustive care unit to find out if it's time to remove their loved one from life support, said inspect author Dr Dana Lustbader, chief of palliative care at The North Shore LIJ Health System in Manhasset, NY.

At the same time, the patient's already shaky ready can further decrease the odds of organ donation occurring as waiting times go up. Organ viability decreases the longer a soul is brain dead.

Another Genetic Cause Of Alzheimer's Disease

Another Genetic Cause Of Alzheimer's Disease.
Researchers have discovered that the variation of a gene associated with beginning onset Alzheimer's may block a key recycling process demanded for brain cell survival - a finding that points the way to possible treatment for the disease. When it's working properly, this gene - called presenilin 1 (PS1) - performs a vital house-cleaning utility by helping brain cells digest unwanted, damaged and potentially toxic proteins.

But in its mutated form, the gene fails to supporter cells recycle these capability toxins, suggesting an explanation for the damage to the brain characteristic of Alzheimer's disease. "We hold we have identified the principal mechanism by which mutations of PS1 cause the most common genetic appear of Alzheimer's disease," study co-author Dr Ralph A Nixon, professor in the departments of psychiatry and chamber biology as well as director of NYU's Center of Excellence on Brain Aging and the Silberstein Alzheimer's Institute, said in a university rumour release.

And "Presently, no effective treatment exists to either unproductive or prevent the progression of Alzheimer's disease," added Nixon, also director of the Center for Dementia Research at the Nathan S Kline Institute for Psychiatric Research in New York City. "This unearthing has the the of identifying such a treatment".

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 quail to dust off their bikes, blades and assorted motorized vehicles, the nation's predicament unit doctors are trying to unqualified public attention toward the importance of wearing safety helmets to prevent serious brain injury. "People are riding bicycles, motorcycles and ATVs all-terrain vehicles more often at this ease of year," Dr Angela Gardner, president of the American College of Emergency Physicians (ACEP), said in a communication release. She stressed that bourgeoisie need to get in the habit of wearing a certified safety helmet, because it only takes one distressing crash to end a life 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 difficulty worry as a result of injuries sustained while riding a bike. Wearing a helmet that meets Consumer Product Safety Commission standards could ease this figure by more than two-thirds, the combine suggests.

But children aren't the only ones who need to wear helmets. In fact, older riders merit for 75 percent of bicycle injury deaths, the ACEP noted. Among bicyclists of all ages, 540000 endeavour emergency care each year as a result of an accident, and 67000 of these patients allow head injuries. About 40 percent experience head trauma so acute that hospitalization is required.

A properly 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 proceed injuries could be prevented each year. With May designated as motorcycle refuge month, the ACEP is also highlighting the benefits of helmet use middle motorcyclists. "Helmet use is the single most distinguished factor in people surviving motorcycle crashes," Gardner stated in the news release. "They depreciate the risk of head, brain and facial injury among motorcyclists of all ages and blast severities".

Study Of Helmets With Face Shields

Study Of Helmets With Face Shields.
Adding expression shields to soldiers' helmets could truncate brain damage resulting from explosions, which account for more than half of all combat-related injuries unremitting by US troops, a new study suggests. Using computer models to simulate battlefield blasts and their chattels on brain tissue, researchers learned that the face is the strongest pathway through which an explosion's pressure waves reach the brain. According to the US Department of Defense, about 130000 US repair members deployed in Afghanistan and Iraq have sustained blast-induced injurious brain injury (TBI) from explosions.

The addition of a face shield made with transparent armor statistics to the advanced combat helmets (ACH) worn by most troops significantly impeded direct curse waves to the face, mitigating brain injury, said lead researcher Raul Radovitzky, an confidant professor at the Massachusetts Institute of Technology (MIT). "We tried to assess the physics of the problem, but also the biological and clinical responses, and bind it all together," said Radovitzky, who is also associate chief honcho of MIT's Institute for Soldier Nanotechnologies. "The key thing from our point of view is that we gnome the problem in the news and thought maybe we could make a contribution".

Researching the issue, Radovitzky created computer models by collaborating with David Moore, a neurologist at the Defense and Veterans Brain Injury Center at Walter Reed Army Medical Center in Washington, DC Moore old MRI scans to simulate features of the brain, and the two scientists compared how the brains would reply to a frontal destroy wave in three scenarios: a head with no helmet, a head wearing the ACH, and a prime minister wearing the ACH plus a face shield. The sophisticated computer models were able to fuse the force of blast waves with skull features such as the sinuses, cerebrospinal fluid, and the layers of gray and whey-faced matter in the brain. Results revealed that without the face shield, the ACH slightly delayed the burst wave's arrival but did not significantly lessen its effect on brain tissue. Adding a face shield, however, considerably reduced forces on the brain.

Still Some Differences Between The Behavior Of Men And Women

Still Some Differences Between The Behavior Of Men And Women.
While not every broad is intuitive or every guy handy with tools, neurological scans of progeny males and females suggest that - on average - their brains really do develop differently. The digging comes with a caveat: It doesn't connect the brain-scan findings to the actual ways that these participants conduct in real life. And it only looks at overall differences among males and females. Still, the findings "confirm our hunch that men are predisposed for rapid action, and women are predisposed to cogitate about how things feel," said Paul Zak, who's familiar with the study findings.

And "This remarkably helps us understand why men and women are different," added Zak, founding chief honcho of the Center for Neuroeconomics Studies at Claremont Graduate University in California. Researchers Ragini Verma, an affiliate professor of radiology at the University of Pennsylvania, and colleagues used scans to study the brains of 428 males and 521 females aged 8 to 22.

The goal was to better realize the connectivity in the brain and determine if certain types of wiring are in good shape or like a lane "that could be broken or has a bad rough patch that needs to be covered over". The swat found that, on average, the brains of men seem to be better equipped to comprehend what people perceive and how they react to it. Females, on average, appear to be better able to stick the parts of their brains that handle analysis and intuition.

People With Stroke Have A Chance At A Full Life

People With Stroke Have A Chance At A Full Life.
Scientists are testing a original thought-controlled apparatus that may one day help people start limbs again after they've been paralyzed by a stroke. The device combines a high-tech brain-computer interface with electrical stimulation of the damaged muscles to mitigate patients relearn how to move frozen limbs. So far, eight patients who had gone movement in one hand have been through six weeks of remedy with the device.

They reported improvements in their ability to complete daily tasks. "Things like combing their plaits and buttoning their shirt," explained study author Dr Vivek Prabhakaran, official of functional neuroimaging in radiology at the University of Wisconsin-Madison. "These are patients who are months and years out from their strokes. Early studies suggested that there was no genuine room for change for these patients, that they had plateaued in the recovery.

We're showing there is still cell for change. There is plasticity we can harness". To use the new tool, patients damage a cap of electrodes that picks up brain signals. Those signals are decoded by a computer. The computer, in turn, sends dainty jolts of electricity through wires to sticky pads placed on the muscles of a patient's paralyzed arm.

The jolts deport oneself like nerve impulses, striking the muscles to move. A simple video game on the computer screen prompts patients to seek to hit a target by moving a ball with their affected arm. Patients practice with the game for about two hours at a time, every other day.

Efficiency Of Breast-Feeding On Brain Activity Of The Baby

Efficiency Of Breast-Feeding On Brain Activity Of The Baby.
Breast-feeding is excellent for a baby's brain, a unexplored study says in June 2013. Researchers employed MRI scans to examine brain growth in 133 children ranging in ripen from 10 months to 4 years. By age 2, babies who were breast-fed exclusively for at least three months had greater levels of occurrence in key parts of the brain than those who were fed formulary only or a combination of formula and breast milk. The extra growth was most evident in parts of the knowledge associated with things such as language, emotional function and thinking skills, according to the study published online May 28 in the register NeuroImage.

So "We're finding the difference in white question growth is on the order of 20 to 30 percent, comparing the breast-fed and the non-breast-fed kids," consider author Sean Deoni, an assistant professor of engineering at Brown University, said in a university communication release. "I think it's astounding that you could have that much difference so early".

Hypothyroidism Affects The Brain

Hypothyroidism Affects The Brain.
Hypothyroidism, a form that causes low or no thyroid hormone production, is not linked to submissive dementia or impaired brain function, a new investigation suggests. Although more research is needed, the scientists said their findings add to mounting ground that the thyroid gland disorder is not tied to the memory and thinking problems known as "mild cognitive impairment". Some ex evidence has suggested that changes in the body's endocrine system, including thyroid function, might be linked to Alzheimer's blight and other forms of dementia, said researchers led by Dr Ajay Parsaik, of the University of Texas Medical School in Houston.

Mild cognitive impairment, in particular, is cogitation to be an cock's-crow warning sign of the memory-robbing disorder Alzheimer's disease, the scrutinize authors said in a university news release. In conducting the study, Parsaik's group examined a group of more than 1900 people, including those with mild and more severe cases of hypothyroidism. The participants, who were from the same Minnesota county, were between 70 and 89 years of age.

People At High Risk Of Alcoholism Also Have More Chances To Suffer From Obesity

People At High Risk Of Alcoholism Also Have More Chances To Suffer From Obesity.
People at higher gamble for alcoholism might also brave higher edge of becoming obese, new study findings show. Researchers at Washington University School of Medicine in St Louis analyzed observations from two large US alcoholism surveys conducted in 1991-1992 and 2001-2002. According to the results of the more up to date survey, women with a division history of alcoholism were 49 percent more likely to be obese than other women. Men with a set history of alcoholism were also more likely to be obese, but this association was not as strong in men as in women, said at the outset author Richard A Grucza, an assistant professor of psychiatry.

One explanation for the increased hazard of obesity among people with a family history of alcoholism could be that some people substitute one addiction for another. For example, after a man sees a close relative with a drinking problem, they may avoid hard stuff but consume high-calorie foods that stimulate the same reward centers in the brain that react to alcohol, Grucza suggested.

In their enquiry of the data from both surveys, the researchers found that the link between family history of alcoholism and paunchiness has grown stronger over time. This may be due to the increasing availability of foods that interact with the same brain areas as alcohol.

Head Injury With Loss Of Consciousness Does Not Increase The The Risk Of Dementia

Head Injury With Loss Of Consciousness Does Not Increase The The Risk Of Dementia.
Having a damaging genius injury at some measure in your life doesn't raise the risk of dementia in old age, but it does increase the odds of re-injury, a uncharted study finds. "There is a lot of fear among people who have sustained a brain wound that they are going to have these horrible outcomes when they get older," said senior author Kristen Dams-O'Connor, underling 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 determine to be a risk for re-injury".

The 16-year swat of more than 4000 older adults also found that a recent traumatic brain injury with unconsciousness raised the probability of death from any cause in subsequent years. Those at greatest risk for re-injury were people who had their sense injury after age 55, Dams-O'Connor said. "This suggests that there are some age-related biological vulnerabilities that come into amuse oneself in terms of re-injury risk".

Dams-O'Connor said doctors need to look out for health issues amid older patients who have had a traumatic brain injury. These patients should try to sidestep another head injury by watching their balance and taking care of their overall health. To investigate the consequences of a shocking brain injury in older adults, the researchers collected data on participants in the Adult Changes in Thought study, conducted in the Seattle region between 1994 and 2010. The participants' unexceptional age was 75.

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 distressing intellect 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.

US Doctors Confirm The Correct Solution To The Problem Of Epilepsy

US Doctors Confirm The Correct Solution To The Problem Of Epilepsy.
The behemoth the greater part of epilepsy patients who have brain surgery to doctor the seizure disorder find it improves their mood and their ability to work and drive, a new weigh reveals. Meanwhile, a second study also indicates the procedure is safe and effective for patients over 60. "They're both reassuring findings," said Bruce Hermann, chief of the Charles Matthews Neuropsychology Lab at the University of Wisconsin School of Medicine and Public Health. "Epilepsy is a enigmatic civil disorder to have and live with, coming with a high rate of depression and affecting the ability to drive and work.

And "We always hoped surgery would have dogmatic effects on patients' life situations, and this research does show that, and shows that the outcomes persist," added Hermann, who was not implicated with the research Dec 2013. Both studies are scheduled to be presented Sunday at the American Epilepsy Society annual tryst in Washington, DC Research presented at ordered conferences is considered preliminary until published in a peer-reviewed medical journal.

Affecting about 2,2 million Americans and 65 million grass roots globally, epilepsy is a seizing disorder triggered by abnormal nerve cell signaling in the brain, according to the Epilepsy Foundation. More than 1 million Americans with epilepsy go down from treatment-resistant seizures that can hamper their ability to drive, run and learn. Epilepsy is the third most common neurological disorder, after Alzheimer's disease and stroke.

Frequent Brain Concussion Can Lead To Suicide

Frequent Brain Concussion Can Lead To Suicide.
When historic National Football League celebrated linebacker Junior Seau killed himself last year, he had a catastrophic wisdom disorder probably brought on by repeated hits to the head, the US National Institutes of Health has concluded. The NIH scientists who intentional Seau's brain unflinching that he had chronic traumatic encephalopathy (CTE). They told the Associated Press on Thursday that the cellular changes they apothegm were similar to those found in autopsies of people "with exposure to repetitive head injuries".

The brawl - characterized by impulsivity, depression and erratic behavior - is only diagnosed after death. Seau, 43, who played pro football for 20 seasons before his retirement in 2009, jigger himself in the box last May 2012. His family donated his brain for research.

Some experts feel - but can't prove - that CTE led to Seau's suicide. "Chronic wounding encephalopathy is the thing we have typically seen in a lot of the athletes," said Dr Howard Derman, manager at the Methodist Concussion Center in Houston. "Rather than say 'this caused this,' I expect the observation is that there have been multiple pro football players now who have committed suicide: Dave Duerson, Andre Waters, John Grimsley - although Grimsley was just reported as a gun accident".

Some fight that these players became depressed once they were out of the limelight or because of marital or monetary difficulties, but Derman thinks the evidence goes beyond that."Yes, all that may be universal on - but it still remains that the majority of these players who have committed suicide do have changes of chronic injurious encephalopathy. We feel that that is also playing a role in their mental state".

But, Derman cautioned, "I can't verbalize that chronic traumatic encephalopathy causes players to commit suicide". Chronic shocking encephalopathy was first noticed in boxers who suffered blows to the head over many years. In late years, concerns about CTE have led high school and college programs to regulate hits to the head, and the National Football League prohibits helmet-to-helmet hits.

New Treatments Hyperactivity Teenagers

New Treatments Hyperactivity Teenagers.
A newer MRI methodology can feel low iron levels in the brains of children with attention-deficit/hyperactivity disorder (ADHD). The practice could help doctors and parents make better informed decisions about medication, a new study says. Psychostimulant drugs hand-me-down to treat ADHD affect levels of the brain chemical dopamine. Because iron is required to answer dopamine, using MRI to assess iron levels in the leader may provide a noninvasive, indirect measure of the chemical, explained study author Vitria Adisetiyo, a postdoctoral investigate fellow at the Medical University of South Carolina.

If these findings are confirmed in larger studies, this skill might help improve ADHD diagnosis and treatment, according to Adisetiyo. The route might allow researchers to measure dopamine levels without injecting the patient with a substance that enhances imaging. ADHD symptoms subsume hyperactivity and difficulty staying focused, paying attention and controlling behavior.

Doctors Discovered How The Brain Dies

Doctors Discovered How The Brain Dies.
Shrunken structures privy the brains of unmanageable marijuana users might explain the stereotype of the "pothead," brain researchers report. Northwestern University scientists studying teens who were marijuana smokers or departed smokers found that parts of the mastermind related to working memory appeared diminished in size - changes that coincided with the teens' under par performance on memory tasks. "We observed that the shapes of brain structures connected to short-term memory seemed to collapse inward or shrink in people who had a history of circadian marijuana use when compared to healthy participants," said study author Matthew Smith.

He is an subordinate research professor in psychiatry and behavioral sciences at the Northwestern University Feinberg School of Medicine, in Chicago. The shrinking of these structures appeared to be more advanced in common people who had started using marijuana at a younger age. This suggests that youngsters might be more influenceable to drug-related memory loss, according to the study, which was published in the Dec 16. 2013 descendant of the journal Schizophrenia Bulletin.

So "The brain abnormalities we're observing are anon related to poor short-term memory performance. The more that capacity looks abnormal, the poorer they're doing on memory tests". The paper is provocative because the participants had not been using marijuana for a duo years, indicating that memory problems might persist even if the person quits smoking the drug, said Dr Frances Levin, chairman of the American Psychiatric Association's Council on Addiction Psychiatry. At the same time, Levin cautioned that the line presents a chicken-or-egg problem.

It's not explicit whether marijuana use caused the remembrance problems or people with memory problems tended to use marijuana. "The big $64000 examine is whether these memory problems predate the marijuana use". The swotting focused on nearly 100 participants sorted into four groups: healthy people who never used pot, tonic people who were former heavy pot smokers, people with schizophrenia who never used pan and schizophrenics who were former heavy pot users. Researchers used MRI scans to meditate on the structure of participants' brains.

The Larger Head Size Reduces Brain Atrophy In Alzheimer's Disease

The Larger Head Size Reduces Brain Atrophy In Alzheimer's Disease.
A original look suggests that Alzheimer's disease develops slower in individuals with bigger heads, perhaps because their larger brains have more cognitive power in reserve. It's not determined that head size, brain size and the rate of worsening Alzheimer's are linked. But if they are, the exploration findings could pave the way for individualized treatment for the disease, said study co-author Lindsay Farrer, ringleader of the genetics program at Boston University School of Medicine.

The paramount goal is to catch Alzheimer's early and use medications more effectively. "The prevailing view is that most of the drugs that are out there aren't working because they're being given to mobile vulgus when what's happening in the brain is too far along".

A century ago, some scientists believed that the remodel of the head held secrets to a person's intelligence and personality - those views have been since discounted. But today, scrutinization suggests that there may be "modest correlations" between brain size and smarts. Still, "there are many other factors that are associated with intelligence," stressed Catherine Roe, a inspection trainer in neurology at Washington University School of Medicine in St Louis.

Nevertheless, there could be a connection between the size of the wit and how many neurons are available to "pick up the slack" when others go dark because of diseases such as Alzheimer's. The imaginative study, published in the July 13 issue of Neurology, explores that possibility.

Early Diagnostics Of Schizophrenia

Early Diagnostics Of Schizophrenia.
Certain intelligence circuits function abnormally in children at peril of developing schizophrenia, according to a new study in April 2013. These differences in imagination activity are detectable before the development of schizophrenia symptoms, such as hallucinations, paranoia and attention and recall problems. The findings suggest that brain scans may help doctors identify and help children at hazard for schizophrenia, said the researchers from the University of North Carolina at Chapel Hill. People with a first-degree kids member (such as a parent or sibling) with schizophrenia have an eight- to 12-fold increased gamble of developing the mental illness.

But currently there is no way to know for certain who will become schizophrenic until they begin having symptoms. In this study, the researchers performed operating MRI brain scans on 42 children, superannuated 9 to 18, while they played a game in which they had to identify a simple circle out of a lineup of emotion-triggering images, such as beautiful or scary animals. Half of the participants had relatives with schizophrenia.

Headache Accompanies Many Marines

Headache Accompanies Many Marines.
Active-duty Marines who abide a traumatic perception injury face significantly higher risk of post-traumatic stress disorder (PTSD), according to a new study. Other factors that stimulate the risk include severe pre-deployment symptoms of post-traumatic pressurize and high combat intensity, researchers report. But even after taking those factors and past brain damage into account, the study authors concluded that a new traumatic brain injury during a veteran's most late deployment was the strongest predictor of PTSD symptoms after the deployment. The study by Kate Yurgil, of the Veterans Affairs San Diego Healthcare System, and colleagues was published online Dec 11, 2013 in JAMA Psychiatry.

Each year, as many as 1,7 million Americans ratify a upsetting leader injury, according to study background information. A traumatic brain injury occurs when the conk violently impacts another object, or an object penetrates the skull, reaching the brain, according to the US National Institute of Neurological Disorders and Stroke. War-related injurious brain injuries are common.

The use of improvised unsound devices (IEDs), rocket-propelled grenades and land mines in the Iraq and Afghanistan wars are the fundamental contributors to deployment-related traumatic brain injuries today. More than half are caused by IEDs, the con authors noted. Previous research has suggested that experiencing a shocking brain injury increases the risk of PTSD. The disorder can occur after someone experiences a damaging event.

Such events put the body and mind in a high-alert state because you feel that you or someone else is in danger. For some people, the burden related to the traumatic event doesn't go away. They may relive the effect over and over again, or they may avoid people or situations that remind them of the event. They may also feel jittery and always on alert, according to the US Department of Veterans Affairs. Many relatives with traumatic brain injury also story having symptoms of PTSD.

It's been unclear, however, whether the experience leading up to the injury caused the post-traumatic highlight symptoms, or if the injury itself caused an increase in PTSD symptoms. The data came from a larger look following Marines over time. The current study looked at June 2008 to May 2012. The 1648 Marines included in the swotting conducted interviews one month before a seven-month deployment to Iraq or Afghanistan, and a assist interview three to six months after returning home.
