A new study by UCLA researchers has found that Naltrexone, a drug used to treat alcoholism, may also be a promising treatment for addiction to methamphetamine.

“The results were about as good as you could hope for,” said Lara Ray, a UCLA associate professor of psychology, director of the UCLA Addictions Laboratory and lead author of the new study.

The study, published in the journal Neuropsychopharmacology, was the first in the U.S. to evaluate Naltrexone for treating methamphetamine addiction. Researchers analyzed 22 men and eight women who use methamphetamine an average of three to four days a week.

During a four-day hospital stay, each person was each given either Naltrexone — 25 milligrams the first two days, 50 milligrams on days three and four — or a placebo daily. Ten days later, the subjects were readmitted to the hospital for four more days; those who had taken Naltrexone earlier were given placebos, and vice versa.

UCLA receives $1 million in new funds for role in worldwide ENIGMA brain study
UCLA will receive $1 million in new funding from the National Institutes of Health as part of a global initiative to pool data about the human brain. The Enhancing Neuro Imaging Genetics through Meta-Analysis (ENIGMA) consortium unites brain researchers in 33 countries to discover factors that help or harm the brain.
Two UCLA scientists receive NIH grants to further BRAIN Initiative research
In April 2013, UCLA scientists led by Chancellor Gene Block were among the guests at President Obama’s announcement of the BRAIN Initiative. The program is aimed at discovering new ways to treat, cure and prevent traumatic brain injuries and brain disorders such as Alzheimer’s disease and epilepsy. Today, two UCLA faculty members, Dr. X. William Yang, a professor of psychiatry, and Dr. Daniel Geschwind, a professor of psychiatry, neurology and genetics, were among more than 100 investigators who received funding through the National Institutes of Health’s first wave of investments in research supporting the initiative.
UCLA scientists hunt down origin of Huntington's disease in the brain
The gene mutation that causesHuntington's disease appears in every cell in the body, yet it kills only two types of brain cells. Why? UCLA scientists used a unique approach to switch the gene off in individual brain regions and zero in on those that play a role in causing the disease in mice.Published in the April 28 online edition of the journal Nature Medicine, the research sheds light on where Huntington's starts in the brain. It also suggests new targets and routes for therapeutic drugs to slow the devastating disease, which strikes an estimated 35,000 Americans.
Understanding the basic biology of bipolar disorder
Scientists from UCLA, UC San Francisco, Costa Rica and Colombia take steps to identify genetic component to mental illness  Mark Wheeler, 310-794-2265           Scientists know there is a strong genetic component to bipolar disorder, but they have had an extremely difficult time identifying the genes that cause it. So, in an effort to better understand the illness's genetic causes, researchers at UCLA tried a new approach.
