Can microdosing improve mental health?

How psilocybin could transform mental health treatment

How magical are magic mushrooms, at least where depression is concerned? Some 24 volunteers participated in a study to evaluate the efficacy of using psilocybin in combination with psychotherapy to treat individuals suffering from depression. While some controversies remain about its use—psilocybin is known to cause psychosis sometimes—some scientists think the benefits outweigh the risks.

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.

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.

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.

How can octopuses and MDMA help scientists understand the human brain?

Research shows that psychedelics may induce something called "critical periods" in the adult brain, which can make our brains more open to learning and changing, like they once were back in early childhood. Psychedelics similarly change how social creatures like octopuses behave, which demonstrates that these animals could help us better understand our own neurobiology.

How to avoid a 'bad trip' advice includes relaxing your mind if you experience scary things and not fighting the feeling

In this video, Michael Pollan, author of "This Is Your Mind On Plants," underscores the gaps in existing understanding about the substances and recommends only taking guided experiences, for safety and help. He tackles how psychedelics work, explains microdosing and psychedelic risks, how the substances could be used to treat addiction, and the history of psychedelic stigma.

The 'definitive' history of magic mushrooms

Where did magic mushrooms come from, and how did they get their magical reputation? This article explains the history of the psychedelic fungi from pre-history to now. The earliest concrete evidence of psychedelic mushroom use is 12,000-year-old murals in Northern Australia that portray mushroom iconography. Considering how many species seek out and consume psychoactive substances, such as Siberian reindeer, it's possible human use of these psychedelic mushrooms may predate these murals.

Veterans reported single dose of ibogaine improved TBI, PTSD, anxiety, and depression

Research published in 2024 on the Central African plant-derived drug included 30 male combat vets who received ibogaine treatment in Mexico. It reported significant reductions in multiple mental health conditions and no serious side effects. Other work, however, has shown the substance can cause fatal cardiac arrhythmias, killing at least 19 people between 1990 and 2008. (Some users may encounter a paywall.)

How a dose of MDMA transformed a white supremacist

A man leading a faction of the US white nationalist movement took part in a psychedelic trial on the pleasantness of social touch and came away from it with his beliefs reportedly upended. He left researchers a note on a form, stating, "this experience has helped me sort out a debilitating personal issue. Google my name. I now know what I need to do."

Can the gut microbiome influence personality?

New research suggests the bacteria in our gut—through the hormones and molecules they produce—can contribute to conditions ranging from depression to anxiety, and much more. The findings suggest diets have a direct impact on mental health and may lead to new therapies.

Supplements ahead of exertional heatstroke helped protect mice against brain damage

In the lab, mice dosed with probiotics prior to inducing exertional heatstroke, had better cognitive outcomes. This evidence underscores the links between the gut microbiome and the brain, at least in rodents.

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.

MS Drugs reduce inflammation, helping reduce relapses and slow disease progression

Disease-Modifying Drugs calm the body's inflammatory response to help stave off relapses—when new or existing MS symptoms show up for a day or longer. Avoiding smoking, exercising, reducing stress via mindfulness, checking for vitamin D deficiencies, drinking more water and eating well, all can slow disease progression. [The jury's still out on if HRT around the time of menopause may reduce dementia risk](https://www.thelancet.com/journals/lanhl/article/PIIS2666-7568(25)00122-9/fulltext) Estrogen can reduce inflammation and support neural growth in the brain, and some research has suggested that beginning hormone replacement therapy around menopause—versus later in life—reduces Alzheimer's disease risk. Still, a recent systematic review concluded that taking HRT didn't affect dementia risk, regardless of when women started taking it, so the science remains unsettled.

Can you microdose GLP-1 agonists like Ozempic?

GLP-1 agonists like Ozempic can help with weight loss, diabetes, and anti-inflammation. For some users, normal doses are too much. So, they've started "microdosing"—taking a smaller amount than the lowest increment of the drug available. While not yet backed by clinical trials, some doctors observed positive effects for certain people.

Schizophrenia is being studied with pea-sized 'mini-brains'

Brain organoid research is enabling researchers to study distinct electrical firing patterns associated with schizophrenia. These "mini-brains" that are constructed in the lab from patients' cells could lead to better diagnosis approaches and drug development.

Some claim breathwork can improve mental health, help process trauma, and more

Research shows people who practice breathing exercises see a decrease in depression and stress levels, and that such exercises are about as effective at treating PTSD as conventional approaches. Even something as simple as extending exhales can slow one's heart rate and activate the parasympathetic nervous system.

Artificial lightning can improve the yield of shiitake mushroom growers

Researchers have found that shockwaves produced from lightning strikes homogenously break internal filaments called hyphae, transitioning the mushrooms from a vegetative growth to a fruiting phase. Repeated minor shocks near mushroom logs mimicked this effect.
