Common antidepressants interact with the opioid pain medication tramadol to make it less effective for pain relief, according to a study published in the journal Pharmacotherapy. These findings have important implications for the opioid epidemic, suggesting that some patients suspected of drug-seeking may in fact be under-medicated and just are seeking more effective pain relief. They also could help explain why some people exceed the prescribed dose of tramadol, increasing their risk of addiction.
New research discovers employees who view pornography aren't just costing companies millions of dollars in wasted time, they're causing harm to the company.
A prevailing theory in neuroscience holds that people make decisions based on integrated global calculations that occur within the frontal cortex of the brain. However, Yale researchers have found that three distinct circuits connecting to different brain regions are involved in making good decisions, bad ones and determining which of those past choices to store in memory, they report June 25 in the journal Neuron.
'Our findings suggest that certain types of stores -- tobacco shops, convenience stores and those with a lot of tobacco advertising -- are more likely to sell tobacco to a young person without checking his or her ID.'
The development of neural circuits in youth, at a particularly important time in their lives, can be heavily influenced by external factors -- specifically the frequent and regular use of cannabis. A new study in the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP), published by Elsevier, reports that alterations in cognitive control--an ensemble of processes by which the mind governs, regulates and guides behaviors, impulses, and decision-making based on goals are directly affected.
Young gay and bisexual men are frequent users of alkyl nitrites, or poppers, but few show signs of addiction, risky consumption habits or other psychosocial problems, a study shows.
A new study by researchers at UC Berkeley's Haas School of Business has found that information acts on the brain's dopamine-producing reward system in the same way as money or food. The study is the first to demonstrate a common neural code for information and money.
A new study suggests it may be possible to disarm the emotional memories of trauma that drive PTSD symptoms.
New research from the national psychiatric project, iPSYCH, shows that a specific gene is associated with an increased risk of cannabis abuse. The gene is the source of a so-called nicotine receptor in the brain, and people with low amounts of this receptor have an increased risk of cannabis abuse.
A new study in the Faculty of Public Health's Journal of Public Health, published by Oxford University Press, finds that tobacco and alcohol usage are extremely common in British reality television shows.
