Post-Psychedelic Reductions in Experiential Avoidance Are Associated With Decreases in Depression Severity and Suicidal Ideation

Now I know how to deal with my feelings rather than repress them” (1) Serotonergic psychedelics, a class of pharmacological agents that act as serotonin 2A receptor (5-HT2AR) agonists, including psilocybin, lysergic acid diethylamide (LSD), and dimethyltryptamine (DMT; contained in the brew ayahuasca), are currently receiving attention within psychiatry and mental health as novel interventions for a wide range of mental health concerns [for reviews, see (2, 3)]. Randomized controlled trials and open-label trials have found promising results for psychedelic therapy in the treatment of distress associated with a life-threatening illness [e.g., (4–6)], substance use disorders [e.g., (7–10)], obsessive-compulsive disorder (11), depression [e.g., (12–14)], and suicidal ideation (13, 15).

Experiential Avoidance as a Potential Transdiagnostic Mechanism Psychedelics, Depression, and Suicidal Ideation Summary. Neuroimaging study suggests a single dose of ayahuasca produces lasting changes in two important brain networks. Consuming a single dose of the psychedelic brew ayahuasca can result in lasting changes in higher-order cognitive brain networks, according to a new study published in the Journal of Psychopharmacology.

Ayahuasca, a concoction used for centuries by indigenous Amazon tribes, contains the powerful psychedelic drug dimethyltryptamine (DMT) and monoamine oxidase inhibitors. The brew is typically prepared using leaves from the Psychotria viridis shrub and the bark of the Banisteriopsis caapi vine. The new neuroimaging research suggests that ayahuasca may produce long-lasting effects on mood by altering the functional connectivity of the brain’s salience and default mode networks. “As a clinical neuroscientist, I am interested in approaches that can improve the life of patients with neuropsychiatric disorders,” said study author Lorenzo Pasquini, a postdoctoral fellow at the Memory and Aging Center at the University of California, San Francisco. Anesthesia-Related Memory Loss Lasts Days, Study Warns. People who are put under general anesthesia may wind up with memory and cognitive deficits for days or weeks after surgery.

Anesthesia-Related Memory Loss Lasts Days, Study Warns

But now, a new study in mice reveals a possible way to reverse the ill effects of anesthesia drugs on memory. In the study, scientists gave mice a common anesthetic, and found the drug caused memory impairments that lasted up to a week. But when they gave the mice another drug, after the anesthetic, the memory effects were reversed, the researchers say. The findings suggest that doctors should tell their patients that anesthesia may affect their memory, said Dr. Beverly Orser, a professor of anesthesiology at the University of Toronto, in Canada, co-author of the study published today (Nov. 3) in The Journal of Clinical Investigation. Drug-induced amnesia. Introduction: Skin diseases affect a large percentage of people and can result in a markedly decreased quality of life.

Drug-induced amnesia

Nearly 25% of all physician office visits are for skin complaints, but only about one third of these visits occur with dermatologists. Most of the remaining visits for skin complaints occur with primary care physicians including Family Physicians, Internists, and Pediatricians. Primary care physicians, however, have an ever-increasing knowledge base of medicine to master and receive little formal training in dermatology. Several studies have shown that non-dermatologists have difficulty diagnosing many diseases of the skin. Improving the diagnostic accuracy and dermatologic care that these physicians provide to a large number of patients will significantly impact healthcare quality and cost-effective care by reducing error. New opioid douses pain without being addictive or deadly in primates. While the opioid epidemic continues kill more than 40 American every day, researchers and health experts are frantically searching for ways to curtail use of the highly addictive, pain-quenching drugs.

In March, the Centers for Disease Control and Prevention even released new guidelines directing doctors to simply refrain from prescribing opioids. But if a new study holds up, the health agency may be able to reverse course. Why Is Everyone Freaking Out About MDMA? TheDEA.org: The History of MDMA.
