Brain abnormalities identified that result from prenatal meth exposure
Children whose mothers abused methamphetamine (meth) during pregnancy show brain abnormalities that may be more severe than that of children exposed to alcohol prenatally, according to a study in the March 17 issue of the Journal of Neuroscience. While researchers have long known that drug abuse during pregnancy can alter fetal brain development, this finding shows the potential impact of meth. Identifying vulnerable brain structures may help predict particular learning and behavioral problems in meth-exposed children. (2010-03-16)

PROSPER prevention programs dramatically cut substance abuse among teens
Prevention is often the best medicine, not only for physical health, but also public health, according to researchers at Penn State and Iowa State University. (2013-06-04)

Natural compound mitigates effects of methamphetamine abuse, University of Missouri researchers find
Researchers at the University of Missouri have found that resveratrol may also block the effects of the highly addictive drug, methamphetamine. (2013-11-19)

University of Montana earns army grant to develop drug for traumatic brain injuries
The US Army has awarded University of Montana researcher Dave Poulsen a $1 million grant to further develop a drug that limits damage caused by traumatic brain injuries. (2013-08-20)

Meth addiction mechanism discovered
Researchers have identified, for the first time, long-term changes in the brain circuitry of methamphetamine-addicted mice that can explain why the craving of addiction is so stubborn and long-lived. The research could lead to more effective treatments for addiction to methamphetamine and related drugs. (2008-04-09)

Reward, aversion behaviors activated through same brain pathways
New research at Washington University School of Medicine in St. Louis may help explain why drug treatments for addiction and depression don't work for some patients. The conditions are linked to reward and aversion responses in the brain. And the research suggests that some treatments simultaneously stimulate reward and aversion responses, resulting in a net zero effect. (2015-09-02)

New American Chemical Society podcast: Toward a vaccine for methamphetamine abuse
Scientists are reporting development of three promising formulations that could be used in a vaccine to treat methamphetamine addiction -- one of the most serious drug abuse problems in the United States. That's the topic of the latest episode in the American Chemical Society's (ACS) award-winning 'Global Challenges/Chemistry Solutions' podcast series. (2011-09-14)

Scripps research study links chronic methamphetamine abuse and cardiovascular disease
Scientists at the Scripps Research Institute have found that chronic abuse of the highly addictive drug methamphetamine may be an unrecognized risk factor in the development of a number of potentially serious cardiovascular disorders frequently reported by methamphetamine abusers. (2007-06-25)

Stress steroid mediated withdrawal anxiety in dependent rats reversible by flumazenil
SUNY Downstate Medical Center announced today that Sheryl Smith, Ph.D., professor of physiology and pharmacology, has published new findings demonstrating a reproducible pathology that may help shed light on anxiety and mood volatility in methamphetamine dependence. (2013-10-07)

Brain protein central to both Parkinson's, drug addiction identified
Scientists have identified a protein that appears not only to be central to the process that causes Parkinson's disease but could also play a role in muting the high from methamphetamine and other addictive drugs. The action of the protein, known as organic cation transporter 3 or oct3, fills a longstanding gap in scientists' understanding of the brain damage that causes symptoms like tremor, stiffness, slowness of movement and postural instability. (2009-05-04)

Brain region recovery possible in former methamphetamine users
Adaptive changes in chemical activity in certain regions of the brain of former methamphetamine users who have not used the drug for a year or more suggest some recovery of neuronal structure and function, according to an article in the April issue of Archives of General Psychiatry, one of the JAMA/Archives journals. (2005-04-04)

Proposed addiction treatment successful, safe in second small trial
