ADHD: Scientists discover brain’s anti-distraction system

ADHD: Scientists discover brain’s anti-distraction system

Two Simon Fraser University psychologists have made a brain-related discovery that could revolutionize doctors’ perception and treatment of attention-deficit disorders. This discovery opens up the possibility that environmental and/or genetic factors may hinder or suppress a specific brain activity that the researchers have identified as helping us prevent distraction. The Journal of Neuroscience has just published a paper about the discovery by John McDonald, an associate professor of psychology and his doctoral student John Gaspar, who made the discovery during his master’s thesis research.

Impact of childhood bullying still evident after 40 years

The negative social, physical and mental health effects of childhood bullying are still evident nearly 40 years later, according to new research by King’s College London. Continue reading

Radiation therapy for cervical cancer increases risk for colorectal cancer

Radiation therapy for cervical cancer increases risk for colorectal cancer

Researchers at the University of Texas Medical Branch at Galveston are the first to recommend that young women treated with radiation for cervical cancer should begin colorectal cancer screening earlier than traditionally recommended. The UTMB researchers, finding a high incidence of secondary colorectal cancers among cervical cancer survivors treated with radiation, offer new recommendations that the younger women in this group begin colorectal cancer screening about eight years after their initial cervical cancer diagnosis instead of waiting until age 50 Continue reading

New technique detects microscopic diabetes-related eye damage

New technique detects microscopic diabetes-related eye damage

Indiana University researchers have detected new early-warning signs of the potential loss of sight associated with diabetes. This discovery could have far-reaching implications for the diagnosis and treatment of diabetic retinopathy, potentially impacting the care of over 25 million Americans. “We had not expected to see such striking changes to the retinas at such early stages,” said Ann Elsner, professor and associate dean in the IU School of Optometry and lead author of the study.

Suicide epidemic among India’s ‘marginalized’ farmers

Suicide epidemic among India’s ‘marginalized’ farmers

A new study has found that India’s shocking rates of suicide are highest in areas with the most debt-ridden farmers who are clinging to tiny smallholdings — less than one hectare — and trying to grow ‘cash crops’, such as cotton and coffee, that are highly susceptible to global price fluctuations. The research supports a range of previous case studies that point to a crisis in key areas of India’s agriculture sector following the ‘liberalization’ of the nation’s economy during the 1990s.

‘Brain training’ overcomes tics in Tourette syndrome, study finds

‘Brain training’ overcomes tics in Tourette syndrome, study finds

Teenagers diagnosed with Tourette Syndrome (TS) were slower than their typically developing peers when asked to perform a task that involved them simply moving their eyes to look at targets. However, they significantly outperformed their peers when the task was more demanding and required them to choose between looking at or away from targets. Continue reading

How kids’ brain structures grow as memory develops

How kids’ brain structures grow as memory develops

Our ability to store memories improves during childhood, associated with structural changes in the hippocampus and its connections with prefrontal and parietal cortices. New research from UC Davis is exploring how these brain regions develop at this crucial time Continue reading

Eavesdropping on brain cell chatter

Eavesdropping on brain cell chatter

Everything we do — all of our movements, thoughts and feelings — are the result of neurons talking with one another, and recent studies have suggested that some of the conversations might not be all that private. Brain cells known as astrocytes may be listening in on, or even participating in, some of those discussions. But a new mouse study suggests that astrocytes might only be tuning in part of the time — specifically, when the neurons get really excited about something. Continue reading

Cancer drugs block dementia-linked brain inflammation, study finds

Cancer drugs block dementia-linked brain inflammation, study finds

A class of drugs developed to treat immune-related conditions and cancer — including one currently in clinical trials for glioblastoma and other tumors — eliminates neural inflammation associated with dementia-linked diseases and brain injuries, according to UC Irvine researchers. In their study, assistant professor of neurobiology & behavior Kim Green and colleagues discovered that the drugs, which can be delivered orally, eradicated microglia, the primary immune cells of the brain. These cells exacerbate many neural diseases, including Alzheimer’s and Parkinson’s, as well as brain injury Continue reading
