New findings in a large MRI study on ADHD suggest the disorder is more neurological than behavioural. The study, self-described by its researchers as the largest-ever MRI study on ADHD--indeed, it's titled Subcortical brain volume differences in participants with attention deficit hyperactivity disorder in children and adults: a cross-sectional mega-analysis--was published Wednesday in The Lancet Psychiatry. [...]
A study published last month in the journal of Nature Neuroscience used MR imaging to research the changes in the brain brought about by pregnancy. The study, entitled 'Pregnancy leads to long-lasting changes in human brain structure', discovered a reduction of gray matter regions pertaining to social cognition in the brains of pregnant women. The research was [...]
A new MRI study has located the cingulate cortex as the brain region responsible for forming positive or negative associations with people's faces. The researchers also experimented with manipulating the emotional responses of their subjects, ie. inducing them to feel a certain way about certain faces. "Face recognition is a very important social function for [...]
Essential tremor, a neurological disorder that affects millions of people, is not a terminal condition but is one that greatly impedes upon quality of life. Characterized by continuous and rhythmic shaking, most often occurring in the hands or voice, sufferers of essential tremor are unable to perform routine tasks such as tying shoelaces or picking [...]
Packing on the pounds may increase your body mass index, but it won't increase brain volume, according to a new MRI study. Although the human brain inevitably shrinks as it ages, researchers have found that the brains of obese subjects appear 10 years older at middle age than their fitter counterparts. The UK study, entitled [...]
A Canadian MRI study has found similarities in the brain scans of children with autism, Obsessive Compulsive Disorder (OCD) and ADHD. The team of Toronto researchers imaged the white matter of 200 young participants in the landmark study. Up until now, autism, OCD and ADHD have been classified and studied as three separate disorders, despite [...]
You're not hungry, you're thirsty. It's almost too easy: dieters everywhere have heard this advice for decades, but now it's been backed up by MRI science. The study, conducted by Wageningen University in the Netherlands, worked with 19 participants to collect the data. Done in three parts, the research looked at MRI scans of the stomach, [...]
While there are injuries inherent in every sport, few expose players to such fast-paced stop-start motions in the lower joints the way basketball does. (Squash is another sport that exposes players to jerking movements, but it has nothing on basketball in terms of popularity!) A recent study published June 22 in the Clinical Journal of [...]
It's not exactly a secret that CT technology, although useful in its diagnostic application, has harmful effects due to the large amounts of ionizing radiology associated with it. But it wasn't until just weeks ago that anyone was aware that the cost of treating cancers induced by CT scanning in the US numbered in the hundred [...]
To ride the elevator or climb the stairs may not seem like an important decision, but when it's a decision you make every day it could have lasting implications on not only your physical fitness, but your cognitive function as well. A new Canadian MRI study from researchers at Concordia University has found that younger-looking [...]
