Medical News Today: Abnormal brain iron levels ‘may be a biomarker of ADHD’

According to a recent study, the number of children diagnosed with attention deficit hyperactivity disorder in the US increased by 42% between 2003-04 and 2011-12. The increase sparked concern that many children are being incorrectly diagnosed with the condition. But a new study published in the journal Radiology details a biomarker of ADHD that is identified through a […]

Huffington Post: Drug Use Linked With Brain Differences In Teens

Teens who have used drugs even just once in their lives have brain characteristics that are different from those who have never used drugs, a new study finds. In the study, the researchers scanned the brains of 71 Mexican-American 16-year-olds, and asked the teens whether they had ever used drugs, including cigarettes, alcohol, marijuana and other drugs. […]

Boston Globe: Study of brain tumor cells reveals genetic diversity, complexity

Genetic tests have become the cutting-edge in cancer treatment, allowing doctors to choose drugs that target genetic mutations carried in a patient’s tumor. But the success of such therapies came with a quick letdown: the drugs eventually stopped working. Tumors turn out to be made up of cells don’t all have identical DNA, meaning that […]

Red Orbit: MRI Brain Scans Detect People With Early Parkinson’s

Oxford University researchers funded by Parkinson’s UK have developed a simple and quick MRI technique that offers promise for early diagnosis of Parkinson’s disease. The team demonstrated that their new MRI approach can detect people who have early-stage Parkinson’s disease with 85% accuracy, according to research published in Neurology, the medical journal of the American Academy […]

The Guardian: Intellectual disability may be caused by prenatal gene mutation

The mutation of a gene vital for foetal brain development could be responsible for impaired mental function in children born with intellectual disabilities, Australian researchers have discovered. The gene, TUBB5, is critical for building connections between nerve cells of the brain involved in speech, sight, co-ordination and higher level cognition, researchers found. It acts as […]

Live Science: ‘Good Health’ Genes Linked to Increased Risk of Brain Cancer

The same gene variants that are linked with having longer caps on chromosome tips and overall good health also may have a downside: They could increase the risk of brain cancer, a new study finds. These new findings may be the first to suggest that people with longer telomeres — the protective stretches of DNA found at […]

Psych Central: Imaging Suggests Evidence of Biological Basis for Adult ADHD

Emerging research discovers adults who have recovered from attention-deficit hyperactivity disorder (ADHD) have different levels of brain activity than adults who still suffer from ADHD. In a new study, MIT neuroscientists discovered key differences in a brain communication network that is active when the brain is at wakeful rest and not focused on a particular […]

The Star: Brain protein may be cause of high rates of depression in perimenopause

A new study suggests that elevated levels of a specific brain protein may explain why so many women experience depression during perimenopause. The work, led by Toronto scientist Dr. Jeffrey Meyer, concludes that high levels of a chemical called monoamine oxidase A, or MAO-A, may be to blame. The protein is known to break down […]
