Berkeley -- New research led by scientists at the University of California, Berkeley, shows for the first time that PET scans can track the progressive stages of Alzheimer's disease in cognitively normal adults, a key advance in the early diagnosis and staging of the neurodegenerative disorder.
In the process, the scientists also obtained important clues about two Alzheimer's-linked proteins - tau and beta-amyloid - and how they relate to each other.
A study by researchers at Bradley Hasbro Children's Research Center confirmed that teens who attend classes about relationships have lower tolerance for aggression and dating violence. Healthier dating attitudes can be acquired after even brief involvement in an anti-violence curriculum.
Co-authored by Meredith C. Joppa, Ph.D., and Christie J. Rizzo, Ph.D., researchers and colleagues on behalf of the BHCRC, the study was published in the Journal of School Health.
CHAMPAIGN, Ill. -- Is cellphone use detrimental to mental health? A new study from the University of Illinois finds that addiction to, and not simply use of, mobile technology is linked to anxiety and depression in college-age students.
The study was published in the journal Computers in Human Behavior.
DENVER, CO - A new study published in Behavioral Sleep Medicine shows that children who are taught at home get more sleep than those who go to private and public schools. The findings provide additional evidence of teens' altered biologicalclocks and support an argument for starting traditional high school later in the morning.
ATLANTA--Genetics and specific brain regions are linked to sex differences in chimpanzees' scratching behavior, a common indicator of anxiety in humans and others primates, according to a research study led by Georgia State University that shows chimpanzees can be models of human mental illness.
Researchers at the Luxembourg Centre for Systems Biomedicine (LCSB) of the University of Luxembourg and partners in Constance, Munich and Bochum are studying the causes of premature ageing of neurons in Parkinson's patients with a defective DJ1 (PARK7) gene. The genetic defect causes changes in the cellular metabolism meaning that neurons are subjected to oxidative stress and an increased immune response in the brain. The study has just been published in the scientific journal Neurobiology of Disease (DOI: 10.1016/j.nbd.2016.01.019).
Geneticists at the University of Helsinki and the National University of Singapore have teamed up to explore the evolution of musical aptitude in the first-ever empirical study of the evolution of music. The Finnish scientists in the project were supported by funding from the Academy of Finland. The study was published in Scientific Reports, a peer-reviewed scientific journal of the Nature Publishing Group.
When college students introduce a new boyfriend or girlfriend to their parents for the first time, Mom and Dad may have lots of questions for the love interest: Where did you grow up? What's your major? What are your plans after graduation?
New research suggests there might be another question worth asking: How do you manage your money?
In the brain, patterns of neural activity are perfectly balanced. The interplay between activating and inhibitory neurotransmitters ensures that the level of activity stays within the physiological range. During an epileptic attack excitation gains the upper hand resulting in the death of neurons. Researchers of the Bonn University Medical School have now discovered a key player in a signal transduction cascade, which protects neurons from hyperexcitation-induced cell death. These results open a new direction for the development of novel therapy options.
Sustained stress erodes memory, and the immune system plays a key role in the cognitive impairment, according to a new study from researchers at The Ohio State University.
The work in mice could one day lead to treatment for repeated, long-term mental assault such as that sustained by bullying victims, soldiers and those who report to beastly bosses, the researchers say.
"This is chronic stress. It's not just the stress of giving a talk or meeting someone new," said lead researcher Jonathan Godbout, associate professor of neuroscience at Ohio State.
Honeybees suffer severe learning and memory deficits after ingesting very small doses of the pesticide chlorpyrifos, potentially threatening their success and survival, new research from New Zealand's University of Otago suggests.
In their study, researchers from the Departments of Zoology and Chemistry collected bees from 51 hives across 17 locations in the province of Otago in Southern New Zealand and measured their chlorpyrifos levels. They detected low levels of pesticide in bees at three of the 17 sites and in six of the 51 hives they examined.
A new study led by Jeffrey P. Brosco, M.D., Ph.D., professor of clinical pediatrics at the University of Miami Miller School of Medicine, has identified a possible correlation between the prevalence of attention-deficit/hyperactivity disorder (ADHD) and increasing academic demands on young children. In an article published in JAMA Pediatrics, Brosco hypothesized that increased academic standards since the 1970s have contributed to the rise in diagnosis of ADHD.
Trial shows risk of suicide re-attempt substantially reduced after a novel psychiatric intervention
Researchers have identified three risk factors that make adults with mental illness more likely to engage in violent behavior. The findings give mental health professionals and others working with adults with mental illness a suite of characteristics they can use as potential warning signs, allowing them to intervene and hopefully prevent violent behavior.
Reston, Va. (March 1, 2016) - A recent study, reported in the March issue of The Journal of Nuclear Medicine, found evidence that genetic influence on cerebral glucose metabolism played a major role in the bilateral parietal lobes and the left temporal lobe of the human brain, while environmental influences after birth dominated in other regions.
