LSD-like drugs may inspire new antidepressants

Psychedelic DMT—part of ayahuasca—shows antidepressant promise in small clinical trial

Proponents say this short-acting psychedelic, formally known as dimethyltryptamine, could be particularly promising for medicinal use because longer-acting psychedelics can sideline someone for hours after a treatment with hallucinations. DMT is the primary psychoactive ingredient in ayahuasca, a psychoactive brew used across various South American cultures for spiritual, social, and medicinal purposes.

Mental health applications of psychedelics

Scientists are investigating psilocybin, ketamine, LSD, and MDMA (also known as ecstasy) as potential treatments for mental health issues. These drugs enable an altered state of consciousness, which can have beneficial or harmful impacts depending on the nature of the experience. Research suggests these drugs can be effective in treating substance use disorders, mental health conditions, including depression and anxiety, and psychiatric disorders, including schizophrenia.

Psychedelics are being fast-tracked for research after a 2026 executive order

Many such compounds (including LSD, psilocybin, and more) are classified as Schedule I drugs—illegal to possess and federally regarded as having no medical use. Researchers say such restrictions have created significant hurdles for formal clinical trials. With this executive order, the FDA will enable work particularly focused on depression, PTSD, and alcohol use disorder.

Psychedelic drugs are having a scientific renaissance

After decades of repression, psychedelic research is making a resurgence. Hear from a host of experts in this 20-minute video on what that could mean for the future of mental health. The current science on psychedelics believes LSD can cause a particular brain network to quiet or deactivate.

LSD's molecular structure closely resembles the neurotransmitter serotonin

Lysergic acid diethylamide (C20H25N3O) is a colorless, odorless, and flavorless chemical compound that can induce altered perception, mood, and cognition. One of its roles in the brain is as a serotonin agonist, meaning it enters serotonin receptors and triggers a fraction of the response the neurotransmitter would typically warrant.

Australian psychiatrists already prescribe psilocybin and MDMA for depression and PTSD

The country green lighted the treatments for July 1, 2023, onward, with MDMA—ectasy—as a post-traumatic stress disorder treatment, and psilocybin—magic mushrooms—as an option for people with treatment-resistant depression.

An overview of modern clinical research on LSD

Researchers have determined that LSD, taken in a medical setting, decreases anxiety related to "life-threatening disease," reduces brain reactivity to fearful faces, increases the meaning and emotional response derived from music, and more. No complications of LSD administration have been observed in medical settings, though acute adverse effects, including exhaustion, nausea, and difficulty concentrating.

JJ Schildkraut theorized depression is linked to brain chemical imbalances—in 1965

Schildkraut was one of the first to put forward this idea, which stemmed from lab animal research. A decade later, researchers published the first landmark paper on fluoxetine—better known by trade name Prozac—which increases serotonin levels in the brain.

US FDA recently approved the first new schizophrenia drug in decades

Though other antipsychotics block dopamine receptors, a new drug, Cobenfy, influences dopamine levels via a different pathway—it stimulates a pair of specialized receptors in the brain that control the release of a substance called acetylcholine. This alternative approach may help patients avoid serious side effects like weight gain. (Some users may experience a paywall.)

LSD was discovered accidentally after its inventor touched his face and hallucinated

Unlike many drugs, the first time a human ever tripped on acid was recorded first-hand by a scientist. Swiss chemist Albert Hofmann, curious about the "not unpleasant intoxicated-like condition" that overcame him after an accidental exposure, set up a rigorous experiment to test the drug's effects on himself.

An LSD scientist's role in a US mind control project

Within a decade of LSD's discovery, the US government had launched a secret initiative involving hypnosis and hallucinogens. LSD researcher Louis Jolyon West conducted experiments for the CIA's MKUltra project, which focused on the potential of mind control. He later took part in a criminal trial that hinged on testimony whose sourcing was seemingly inspired by MKUltra experiments. This article explores light shed by West's personal archive.

Bupropion is the only antidepressant approved for the preventive treatment of SAD

Clinical trials showed a 44% reduction in risk for recurrence of SAD for those who took the drug compared to a placebo group. Bupropion is a norepinephrine–dopamine reuptake inhibitor, which increases dopamine (other common antidepressants, known as selective serotonin reuptake inhibitors, sometimes can suppress dopamine, but not always).

GLP-1 drugs are under investigation for treating Alzheimer's, Parkinson's, and drug addiction

Researchers are investigating GLP-1 applications for a variety of chronic conditions. One area of interest stems from how study participants using GLP-1 for diabetes and obesity reported describing less longing for wine and cigarettes while taking the medication—intriguing researchers about using the drugs for addiction applications. The drug, they theorize, could bind to receptors that mediate desire. (Some users may experience a paywall.)

'Brave New World' author Aldous Huxley turned to LSD on his deathbed

As "Brave New World" author Aldous Huxley lay dying of cancer in 1963, he asked his wife Laura to dose him with the hallucinogen LSD. A month later, Laura Huxley wrote a letter detailing the author's final trip, which she notes ended "so slowly, so gently, like a piece of music just finishing in a sempre piu piano dolcemente."

How scientists are using molecules found in acidophiles to develop new medical treatments

The Berkeley Pit, an open-pit copper mine in Butte, Montana, that ceased operations in 1982 and is now filled with highly acidic water, is home to various species of fungi and yeast. These extremophiles produce unique compounds that may have anti-inflammatory benefits and have already been used to create an antibiotic for staph infections.

Gene expression patterns are similar between ASD, schizophrenia, and bipolar disorder

Postmortem brain tissue analysis suggests there are genetic and epigenetic similarities between individuals with autism, schizophrenia and bipolar disorder. All three conditions appeared to have activation of genes in astrocytes and suppression of specific genes that function at the junction between neurons, called synapses. (Some users may encounter a paywall.)

Opioids mimic naturally produced endorphins to dull pain

Once in the body, opioids bind to naturally occurring opioid receptors typically used by endorphins to temper pain. They trigger the release of dopamine, a desire-related hormone, and decrease noradrenaline, a neurotransmitter involved in heart and breathing rate regulation, meaning high doses can slow these processes to dangerous levels.

Support groups can offer insights into current and potential treatments

Beyond connecting with patients with similar experiences, support groups can also become centers for advocacy and for sharing research advances and medical experiences, including potential side effects from novel therapies or clinical trials.

Doctors are prescribing social activities—and seeing good results

Physicians, especially in the UK, are asking patients what they enjoy and then prescribing a consistent regimen of doing that type of activity to improve fitness and overall health, including community exercise classes, volunteering, and spending time in nature. This approach may provide better incentives to stick with an activity.

Post-treatment Lyme disease syndrome may be caused by bacterial remnants in the liver

PTLDS, which refers to lingering symptoms of Lyme after antibiotic treatment, is an area of active research. Rodent research published in 2025 suggests that these ongoing symptoms may potentially be due to the body's inflammatory response to lingering cellular components from the bacteria that cause Lyme, Borrelia burgdorferi. In rodents, components of the bacteria's cellular wall may remain in the liver after the bacteria were eliminated with antibiotics.
