In 1972, Britain bumped up the total school years mandated for its children from 15 to 16 years.
That created a "natural experiment": Would Britons who got that extra year of education fare any better, neurologically, as they aged?
Unfortunately, the answer is "no."
"This surprised us," said study co-author and brain researcher Nicholas Judd
Many people turn to mindfulness meditation to help them manage their chronic pain, a practice that’s been used for centuries.
However, it’s been an open question whether meditation is simply functioning as a placebo, rather than actually quelling pain.
Now, a new study involving brain scans has revealed that's not the case.
Huntington's disease is a devastating, fatal neurological illness with little means of treatment, but a new study in mice offers a glimmer of hope.
Huntington's occurs when inherited genes cause key proteins to fold and clump together within brain cells. Over time, this severely hampers brain function and patients lose the ability to talk, walk, swallow and focus. There's no cure, a...

People who regularly use marijuana experience changes in their brain structure and function, but it’s not clear that cannabis is the cause, a new study finds.
Researchers found specific differences in the brains of people who’d ever used weed, particularly in areas densely packed with cannabinoid receptors. However, genetic analysis couldn’t pin down any specific associa...
Most kids with attention issues won't go on to develop serious psychiatric conditions like psychosis or schizophrenia.
However, a new study finds poor attention spans in childhood, plus certain genes, could play a role in raising the risk for these conditions.
Of course, much more research is needed to pinpoint precursors to psychotic symptoms in a person's teens or 20s, said a t...
