  • First LSD Study In 40 Years Shows Promising Medical Uses

    By Emily Thomas

    After a decades-long pause on LSD medical research, the results of the first LSD study approved by the U.S. Food and Drug Administration in 40 years have put the drug’s potential medical benefits back in the spotlight.

    Picking up where the medical community left off in the ’60s, scientists recently investigated the effects of LSD-assisted therapy on 12 terminally ill patients approaching death. The findings of this controlled study, published Tuesday in the peer-reviewed Journal of Nervous and Mental Disease, showed that LSD paired with psychotherapy alleviated end-of-life anxiety in patients suffering from terminal illnesses.

    Conducted in Switzerland, where scientist Albert Hoffman first synthesized LSD in 1938, the study separated the 12 patients into two groups that underwent two preparatory therapy sessions before being administered LSD. For the trial, patients stopped taking any anti-anxiety or antidepressant medications and avoided alcohol for 24 hours prior to the study. One group was administered 200 micrograms of LSD and the other group 20 micrograms (a barely noticeable dosing). Each individual underwent two dosing sessions separated by a few weeks and were assisted by therapists, who walked them through their experiences with the psychedelic’s effects. No prolonged negative effects of the drug were reported.

    The low-dosage group reported that their anxiety got worse, while the higher-dosage group said their drug-therapy sessions had profound positive effects on their anxiety — a clinical indication that psychedelic therapy may have potential as a medical treatment. In follow-up sessions, patients reported their reduced anxiety levels were maintained.

    “People are more scared of dying than they are of using drugs. That’s why we were able to start LSD research with people who were anxious about dying, that and the combination of Albert Hoffman and good contacts with the Swiss equivalent of the FDA,” Rick Doblin, founder of the Multidisciplinary Association for Psychedelic Studies, which largely funded the study, told The Huffington Post over the phone.

    Neal M. Goldsmith, Ph.D., a New York-based psychotherapist and author of the book Psychedelic Healing, explained the significance of this research to HuffPost. “It has long-term implications for society. In the short term it’s going to help patients, people. So the question really becomes, what’s the benefit of a spiritual epiphany or relief or relaxation? And what’s the effect of that on a dying patient?” he said. “We’re going to be a better society once we learn to reintegrate psychedelics. It both requires changes in society and it creates changes.”

    While it is unknown from a medical standpoint what exactly happens to the brain under the effects of LSD, Doblin said the psychoactive ingredients interact with the brain’s filtering system and allow for suppressed thoughts and feelings to reveal themselves, making way for confrontation and potentially for healing.

    Doblin said LSD-assisted therapy is partly a cathartic and mystical experience, a transcendence of time and space that helps patients fearing death shift their thinking from focusing on the time they don’t have left to the time they do have.

    “Something is fundamentally changed by successful LSD-assisted psychotherapy,” he said. “That’s not to say it works in everybody, but there can be permanent changes in people’s attitudes and in their brains.”

    A patient named Peter, who was involved in the study, told The New York Times about his experiences. “I had what you would call a mystical experience, I guess, lasting for some time, and the major part was pure distress at all these memories I had successfully forgotten for decades,” he said. “These painful feelings, regrets, this fear of death. I remember feeling very cold for a long time. I was shivering, even though I was sweating. It was a mental coldness, I think, a memory of neglect.”

    That sentiment of the psychedelic’s effects on the psyche is not isolated to this trial. A 2012 study, published in the Journal of Psychopharmacology, showed that LSD had a “significant beneficial effect” on alcohol abuse. In that trial of 500 patients, 59 percent of those who were administered LSD showed reduced levels of alcohol misuse.

    LSD was officially made illegal in the U.S. in 1966 as a result of “increased nonmedical use,” shutting down all research of its potential medical benefits. Now LSD is classified as a Schedule I substance alongside heroin and marijuana, meaning it is considered to serve no legitimate medical purpose and has a high potential for abuse.

    As the FDA begins to loosen its restrictions on researching psychedelics’ therapeutic capabilities, studies are emerging from many major university medical research communities. Johns Hopkins University is conducting a study of psilocybin (the psychedelic compound found in certain mushroom species) and its effects on cancer patients to find out if the substance can produce personally and spiritually meaningful experiences. New York University’s Psilocybin Cancer Project is also investigating the psychedelic’s effect on reducing depression and anxiety in cancer patients. At Harvard Medical School, a study of MDMA sessions with cancer patients suffering from end-of-life anxiety is in the works.

    “LSD was the last of the drugs to re-enter the lab, because it’s the quintessential symbol of the ’60s. So our ability to do this study and the publication of the article in The New York Times is the culmination of the end of the suppression of psychedelic research,” Doblin told HuffPost.

    The Swiss group’s first clinical trial is just a small step toward what some scientists hope will bring psychedelic therapy to the mainstream through a medical route, following the decades-long halt in research. A larger study pool, Doblin said, would prove that LSD has a place in the medical community.

    “Let’s say that we had the money to have studies that were just like we did that had 400 subjects, two large scale phase-three studies. The results of this study, if we could show with that many people, would be enough to prescribe [LSD] as medicine,” Doblin said. “The political suppression of this research is over. I don’t think the genie is going to be put back in the bottle.”

  • Hearing Loss Tied to Depression in Study

    Hearing Loss Tied to Depression in Study

    Women, non-seniors more likely to be affected this way, researchers say

    Day-to-day noises like rattling cutlery can seem

    THURSDAY, March 6, 2014 (HealthDay News) -- Hearing loss is associated with depression among American adults, especially women and those younger than age 70, according to new research.

    While other studies previously have found the same link, many of them looked only at older adults or at specific regions or ethnicities, and results have been mixed, the researchers pointed out.

    In the new study, as hearing declined, the percentage of depressed adults increased -- from about 5 percent in those who had no hearing problems to more than 11 percent in those who did.

    "We found a significant association between hearing impairment and moderate to severe depression," said study author Dr. Chuan-Ming Li, a researcher at the U.S. National Institute on Deafness and Other Communication Disorders. "The cause-and-effect relationship is unknown," Li said, citing a need for further studies.

    The study was published online March 6 in JAMA Otolaryngology--Head & Neck Surgery.

    The new findings make sense, according to two experts in the field who reviewed the study conclusions.

    "It is not surprising to me that they would be more likely to be depressed," said James Firman, president and CEO of the National Council on Aging. "People with hearing loss, especially those who don't use hearing aids, find it more difficult to communicate with other people, whether in family situations, social gatherings or at work."

    Experts who care for those with hearing loss have long noticed the link, said Robert Frisina, director of the Global Center for Hearing & Speech Research at the University of South Florida, in Tampa. "When they come in [to see about their hearing], they mention this," he said.

    Even so, Frisina noted, the study is valuable because it adds solid data to the anecdotal information.

    For the new study, the researchers looked at data from the U.S. National Health and Nutrition Examination Survey, including more than 18,000 adults aged 18 and older. The younger people self-reported on their hearing status, while hearing tests were given to those 70 and older. All participants filled out a questionnaire designed to reveal depression.

    As hearing loss became worse, the depression did, too, except among those who were deaf. These adults, Frisina said, may be accustomed to coping with the loss.

    Hearing loss was linked with an increased risk of depression in adults of all ages, but was most pronounced in the respondents aged 18 to 69, the investigators found. Women had higher rates of depression than men did.

    Among those 70 and older, no link was found between self-reported hearing loss and depression. However, a link was found for women in this age group if the hearing test found a hearing loss.

    That could be because women start to lose hearing in higher frequencies after age 65, and those frequencies are crucial to understand speech in noisy environments, the study authors noted.

    While it is difficult to sort out cause and effect, Frisina said, the researchers did take into account other conditions that could affect hearing, including trouble seeing, and the link held. "It's probably a pretty strong link," he added.

    Those who think they are having trouble hearing should seek help, he suggested. Often, family and friends notice the loss first. "If you have hearing loss, you need to go to an audiologist and otolaryngologist and have it diagnosed properly, and then you can look at treatment options," Frisina said.

    Researchers Say the Chemical Gets Into Money From Contact With Cash Register Receipts
    Aug. 12, 2011 -- Paper money may contain trace levels of bisphenol A (BPA), a chemical found in some plastics and other consumer products, a study shows.
    But only small amounts of BPA are absorbed through our skin when we handle the money, the study shows.
    The study is published in Environmental Science & Technology.
    BPA is considered an endocrine disruptor, which means it looks or acts like a hormone in the body. It may be associated with behavioral and reproductive issues. Young children may be particularly vulnerable to these effects. As a result, many manufacturers have taken steps to eliminate the BPA in baby bottles and some sippy cups.
    The study analyzed BPA levels in 156 forms of paper money from 21 countries. All of them contained some BPA.
