While marijuana doesn't necessarily shrink your brain cells, it does change them, according to a pair of new studies. The studies were both published in the Journal of the American Medical Association's JAMA Psychiatry. In the first study, researchers used magnetic resonance imaging to compare the brains of marijuana users to non-users.
People with autism might be more creative problem solvers and divergent thinkers, according to a new study. The British study, published in the Journal of Autism and Developmental Disorders, involved the analysis of data from 312 people who took part in a series of tests on creativity.

A new report from an American Psychological Association taskforce states that there is no single factor to constitute a link between violent video games and a rise in criminal behavior, but there is a relationship between the two.

Kids who are picky eaters, even moderately picky eaters, are more prone to developing mental health afflictions, including anxiety, depression, and attention deficit disorder, according to a new study.

Insomniacs' brains may work differently to those who sleep regularly, according to a study from researchers at the Johns Hopkins Medical Center. In fact, results suggested insomnia might be associated with a beneficial trait related to brain flexibility.
Brain injuries during early childhood could lead to attention deficits in later childhood, according to a new study from researchers at VU University Amsterdam in the Netherlands. For the study the researchers examined health records between the ages of six and 13. They examined a total of 113 kids that suffered brain injuries and another 53 that suffered a form of trauma.
Those who drink excessive amounts of coffee may be at an increased risk for suffering Alzheimer's disease and dementia, according to a new study from researchers in Italy.

High blood sugar associated with prediabetes may increase the risk for Alzheimer's disease, a new study suggests. The study, published online in JAMA Neurology, involved researchers conducting memory tests on 150 adults with no mental impairments, at average age of 61. The researchers also measured insulin resistance and had the participants undergo a PET brain scan.
A new series of studies suggests that women's brains may be more vulnerable to contracting Alzheimer's disease than men. The studies were presented at the Alzheimer's Association International Conference in Washington, D.C. Another study suggests that women's daily activities and cognitive abilities decline faster than men's after undergoing surgery with general anesthesia.
