Associations Between Escitalopram and Psilocybin Therapy and Brain Resting-State Functional Connectivity in Major Depressive Disorder

mycolabadmin

This study compared how two depression treatments—a common antidepressant called escitalopram and psilocybin therapy—affect brain connectivity and depression symptoms. Both treatments reduced feelings of lacking pleasure and impulsive behaviors in depressed patients. The research found that while both worked, they affected different parts of the brain’s reward system in distinct ways, suggesting they may work through different mechanisms.

Exploring the Therapeutic Potential of Ketamine and Psilocybin in Comparison to Current Treatment Regimens for Treatment-Resistant Depression, Mood Disorders, and Post-traumatic Stress Disorder in the Pediatric Population: A Narrative Review

mycolabadmin

This review examines two emerging psychiatric treatments—ketamine and psilocybin—for treating hard-to-treat mental health conditions in children and teenagers. Both work by affecting brain chemicals differently than traditional medications and can provide rapid symptom relief, sometimes within hours or days rather than weeks. The study found promising results for depression, anxiety, PTSD, and bipolar disorder, though researchers emphasize that more studies are needed to ensure these treatments are safe for developing brains and that careful ethical guidelines must be established.

Sex-specific effects of psychedelic drug exposure on central amygdala reactivity and behavioral responding

Researchers studied how psilocybin’s active form affects the brain’s fear center in both male and female rats. They found that a single dose produced different effects in males versus females, with males showing lasting reductions in fear responses over 28 days while females showed variable changes. These findings help explain why psychedelics might work differently between sexes and could inform how they’re used to treat anxiety and depression in humans.

Decreases in State and Trait Anxiety Post-psilocybin: A Naturalistic, Observational Study Among Retreat Attendees

mycolabadmin

This study followed 52 people who attended psilocybin retreats in the Netherlands and measured their anxiety levels before, one day after, and one week after the experience. Participants showed significant reductions in both immediate anxiety (state anxiety) and long-term anxiety tendencies (trait anxiety) that lasted up to a week. The anxiety improvements were most strongly linked to feeling a sense of ego dissolution during the experience and to lasting changes in personality traits, particularly becoming less neurotic.

Psychedelic Psilocybin-Assisted Therapy Reduces Depressive Symptoms in Adults with Cancer and Depression

mycolabadmin

Researchers conducted a trial testing psilocybin-assisted therapy in cancer patients with depression. Participants received a single dose of psilocybin combined with therapy sessions. After eight weeks, most patients showed significant improvement in depression symptoms, with many achieving full remission. The treatment was generally safe with only mild side effects, and patients reported feeling more hopeful and better equipped to cope with their cancer diagnosis.

Psychedelics and Suicide-Related Outcomes: A Systematic Review

mycolabadmin

This comprehensive review examined how psychedelic substances like psilocybin and MDMA affect suicidal thoughts. Overall, psilocybin and MDMA-assisted therapy showed promise in reducing suicidal ideation in controlled clinical settings, with effects appearing within weeks. However, LSD use was associated with increased suicidal thoughts. The researchers conclude that while psychedelics show potential, more research is needed to ensure safety and understand how they work.

Psilocybin-induced changes in neural reactivity to alcohol and emotional cues in patients with alcohol use disorder: An fMRI pilot study

mycolabadmin

This pilot study examined how psilocybin affects the brains of people with alcohol use disorder. Using brain imaging (fMRI), researchers found that psilocybin increased activity in brain regions associated with decision-making and emotional control while decreasing activity in regions linked to cravings. These findings suggest psilocybin may help people with alcohol addiction by enhancing their ability to regulate emotions and resist urges to drink.

PolDrugs 2025: results of the third edition of the nationwide study on psychoactive substance use in the context of psychiatry and harm reduction

mycolabadmin

This Polish study surveyed nearly 2,500 recreational drug users about their substance use patterns and mental health. The survey found that marijuana is the most commonly used illicit drug, but worryingly, most users don’t test what they’re taking or measure doses carefully. The study also revealed increasing use of mephedrone and other stimulants that are sending more people to hospitals, while interest in psychedelics is declining. Importantly, more people are now seeing psychiatrists and being honest about their drug use.

Attitudes toward psychedelics and psychedelic-assisted psychotherapy among Australian mental healthcare providers

mycolabadmin

Australian doctors and mental health professionals have positive views about using psychedelics like psilocybin and MDMA to treat depression and trauma, which were recently approved by regulators. However, many still have safety concerns and gaps in their knowledge, particularly psychiatrists. Most doctors learn about psychedelics from podcasts and websites rather than formal training. The study recommends that professional organizations provide better education to prepare healthcare workers for this new treatment approach.

Direct comparison of the acute effects of lysergic acid diethylamide and psilocybin in a double-blind placebo-controlled study in healthy subjects

mycolabadmin

This study directly compared two popular psychedelic drugs, LSD and psilocybin (magic mushrooms), in 28 healthy volunteers. Researchers found that these substances produce very similar mental effects when given at equivalent doses, with the main difference being that LSD lasts longer. The study establishes that about 20 milligrams of psilocybin is roughly equivalent to 100 micrograms of LSD. These findings could help guide dosing for future psychiatric treatments using these psychedelics.
