CINCINNATI--Radiological imaging is being used more often to evaluate stroke diagnosis and outcomes, with penumbra, or tissue that is at risk of progressing to dead tissue but is still salvageable if blood flow is returned, as a potential target for therapy.

However, there have been few studies about what happens to the penumbra without treatment to restore blood flow through the blocked arteries, known as reperfusion treatment.

Washington, D. C. May 25, 2016 -- Teaching is an occupation with a high risk of developing vocal problems -- teachers have more than twice the voice problems than people in other professions, as the voice is the major tool in classroom instruction and is often used for long periods of time and in noisy environments. Additionally, females face a significantly higher risk than men of developing long-term vocal problems. Therefore female teachers, the predominate population of teaching workforce, face a dual risk for developing prolonged voice problem.

Researchers at the University of Bergen in Norway have examined the associations between workaholism and psychiatric disorders among 16,426 working adults.

"Workaholics scored higher on all the psychiatric symptoms than non-workaholics," says researcher and Clinical Psychologist Specialist Cecilie Schou Andreassen, at the Department of Psychosocial Science, at the University of Bergen (UiB), and visiting scholar at the UCLA Semel Institute for Neuroscience and Human Behavior.

Workaholics score higher on all clinical states

Montreal, May 25, 2016 -- Humans aren't much different from other animals. Just like Pavlov's dogs, we can become conditioned to associate environmental cues with rewards. Innocent enough when the sight of your sneakers makes you want to go for a run, but not necessarily so when the sight of the liquor store prompts you to want a drink.

After Alzheimer's, Parkinson's disease (PD) is the leading neurodegenerative disorder, affecting close to a million Americans, with 50,000 new cases diagnosed every year. A progressive disorder of the nervous system affecting movement, PD typically strikes adults in mid-life. In many cases, the spread of the disease to other brain areas leads to Parkinson's disease dementia, characterized by deterioration of memory, reason, attention and planning.

Researchers from the University of Rochester suggest that children raised in poverty may have been mistakenly labeled as "maladapted" for what appears to be a lack of self-control. The new study finds that what looks like selfishness may actually be beneficial behavior that's based on a child's environmental context--that is to say, from being raised in a resource-poor environment.

America is a mobile society, with most children and their families moving once or more during childhood. Moving can bring new opportunities if families relocate to safer, more comfortable homes, or to communities with better schools. However, previous research has found that more frequent residential moves can lead to stress and disrupt children's routines, with negative repercussions for healthy development.

Educators call it the fourth-grade slump: a time when some children, faced with increasingly complex schoolwork, start to lose interest in reading. Yet classroom teachers may not employ the strategies that can get these students back on track, according to speech-language pathology researchers at University of the Pacific.

Mild cognitive impairment (MCI) is a slight but noticeable and measurable decline in cognitive abilities, such as remembering names or a list of items. While changes may not be severe enough to disrupt daily life, a clinical diagnosis of MCI indicates an increased risk of eventually developing Alzheimer's disease or another type of dementia.

Canadian military personnel have higher rates of suicidal thoughts and suicide attempts, but they are also more likely to access mental health support than civilians, found new research in CMAJ (Canadian Medical Association Journal)

Suicide prevention has been a focus in Canada in recent years, with initiatives such as the Mental Health Commission of Canada and major investments in military and veteran mental health aimed at reducing this cause of death. Despite these initiatives, suicide rates have remained mostly unchanged.

INDIANAPOLIS -- The visible impacts of depression and stress that can be seen in a person's face -- and contribute to shorter lives -- can also be found in alterations in genetic activity, according to newly published research.

WASHINGTON -- Google the term "spiked drink," and you'll get more than 11 million hits, directing you to pages that describe being slipped a mickey, tips on how to avoid becoming a victim and even kits to test drinks for illicit drugs. So is drink spiking a growing problem or are these tales of people who just drank too much? Or is this phenomenon merely an urban legend?

TAMPA, Fla. (May 24, 2016) - The current special issue of Technology and Innovation, Journal of the National Academy of Inventors, Volume 18, Number 1 (all open access), is devoted to the evolution of neuroimaging technology, with seven articles chronicling the latest advances in this critical area. In addition, the journal's regular features include the article by the U.S.

TAMPA, Fla. (May 24, 2016) - The effort to find ways to detect and diagnose preclinical Alzheimer's disease (AD) has taken a big step forward with the use of positron emission tomography (PET), a "nuclear medicine" for imaging processes in the body, when PET is used with a special 'tracer' that binds to the amyloid plaques in the brain that are a characteristic cause of AD.
