Research from the University of Rochester finds that caring for others dips during adolescence. But when young people feel supported from their social circles, their concern for others rebound.
Two secrets of one of the brain's most enigmatic regions have finally been revealed. In a pair of studies published in Cell and Neuron, scientists from the Gladstone Institutes have discovered a specific neural circuit that controls walking, and they found that input to this circuit is disrupted in Parkinson's disease. The research reveals two potential new targets to treat movement disorders.
A new study provides some of the first evidence about patterns of marijuana use in states that have legalized medical marijuana. It finds that medical marijuana users are more likely to vaporize or consume edible forms of the drug than recreational users. Researchers also found that 41 percent of people reported having used marijuana recreationally at least once, while only about 7 percent reported using marijuana for medical purposes.
Researchers at Columbia University Medical Center (CUMC) and New York State Psychiatric Institute have found that while cigarette smoking rates have declined among younger people in the United States, those who do smoke are more likely to have a psychiatric or substance use disorder compared with those who began smoking in earlier decades.
Researchers at University of Florida Health have discovered the mechanics of how dopamine transports into and out of brain cells, a finding that could someday lead to more effective treatment of drug addictions and neurological disorders such as Parkinson's disease.
When compared with their heterosexual peers, sexual-minority youth score lower on key indicators of positive youth development -- and those disparities may be due in part to more bullying of these adolescents, University of Pittsburgh Graduate School of Public Health researchers have found.
In a first of its kind study, researchers followed meth-exposed children to age 7.5 and found more supportive home environments could make a difference in their behavior and emotional control.
Policy changes since 2001 had varying effects on the number of people consuming medical marijuana.
Working with mice, researchers at Johns Hopkins have contributed significant new evidence to support the idea that high doses of cocaine kill brain cells by triggering overactive autophagy, a process in which cells literally digest their own insides. Their results, moreover, bring with them a possible antidote, an experimental compound dubbed CGP3466B.
Doctors have no approved medicine to help treat marijuana dependence and abuse, but in small new clinical trial topiramate reduced the amount of cannabis heavy smokers used when they lit up. The results also show, however, that many volunteers couldn't tolerate the drug's side effects.
