Psych Central: Age + Stress = Short-Term Memory Loss

A new study suggests prolonged stress causes a surge in the hormone cortisol, which can result in short-term memory loss among older adults. University of Iowa (UI) researchers have published the study in theJournal of Neuroscience. Short-term increases in cortisol are critical for survival. They promote coping and help us respond to life’s challenges by […]

Health CMi: Acupuncture Reverses Brain Damage After Stroke

A new MRI study finds acupuncture and electroacupuncture effective for treating brain tissue injuries and neurological disorders caused by cerebral ischemia/reperfusion injury (CIRI). This type of brain damage is caused by the return of blood circulation to the brain after a period of ischemia, restricted blood supply. The sudden return of blood to oxygen and […]

Singularity Hub: Scientists Trigger Stem Cells To Produce New Brain Cells

It turns out that an apple a day — or at least an apple spinach salad — does keep the doctor away. But it’s not true that when brain cells die we can’t make more. When and how remain active questions, however, so there’s no free pass to collectively disregard our mothers’ safety tips just yet. Researchers […]

io9: Are We About to Cross the Blood-Brain Barrier, and Transform Medicine?

One of the greatest frustrations for doctors dealing with brain tumors is called the blood brain barrier (BBB). It’s the defense our bodies have created to keep toxins from passing from our blood into our brains — but it also stops medicines from making the crossing too. Now that may be about to change. Today […]

Financial Times: David Cameron launches world’s biggest dementia study

The world’s biggest study of dementia will be unveiled by David Cameron on Thursday as part of a push worth more than £100m to accelerate research into Alzheimer’s and other brain disorders. The UK prime minister will announce the creation of a 2m-strong group of UK volunteers aged 50 and over who will share their medical data and lifestyle […]

US News & World Report: Anxiety May Affect Kids’ Brains

Children with anxiety problems actually have a bigger “fear center” in their brain, researchers report. The study included 76 children aged 7 to 9, which is when anxiety-related traits and symptoms can first be reliably detected, according to the Stanford University School of Medicine researchers. The parents provided information about their youngsters’ anxiety levels, and […]

Daily Digest News: Study: Chronic stress can change the brain

Chronic stress has the ability to change a person’s brain in ways that can affect memory and lead to mental illness. Research out of the University of California, Berkeley has determined that prolonged and excessive levels of stress hormones alter the structure of the brain by causing extra white matter to be produced. Abnormalities in […]

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 […]
