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

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.

Social acceptability of psilocybin-assisted therapy for existential distress at the end of life: A population-based survey

This study surveyed 2,800 Canadians about their views on using psilocybin (a psychedelic compound from certain mushrooms) to help patients with terminal illnesses manage existential distress and anxiety. About 79% of respondents thought it was a reasonable medical option, and 85% believed the government should cover the costs. People who had previous experience with psilocybin, those exposed to palliative care, and those with progressive political views were most supportive of this therapy.

The therapeutic potential of microdosing psychedelics in depression

This review examines whether taking very small doses of psychedelic drugs like LSD and psilocybin might help treat depression. While users report benefits and some studies show subtle positive effects on mood and thinking, scientists have not yet confirmed whether microdosing actually works as a depression treatment. More research with depressed patients is needed to understand if this approach is truly helpful and safe for regular use.

Psychotomimetic compensation versus sensitization

This paper proposes a new way to understand why drugs that can cause psychosis-like effects (such as psilocybin, LSD, and ketamine) can also help treat depression and anxiety. The authors suggest that these drugs trigger compensatory responses in the brain that temporarily help us cope with stress, similar to how a runner’s high feels good during exercise. However, if someone uses these drugs repeatedly or experiences chronic stress, they may become sensitized and more vulnerable to developing actual psychotic symptoms over time.

Psilocybin microdosers demonstrate greater observed improvements in mood and mental health at one month relative to non-microdosing controls

This study followed nearly 1000 people who microdose psilocybin (small regular doses of psilocybin mushrooms) and compared them to 180 people who don’t microdose over one month. Microdosers showed greater improvements in mood, depression, anxiety, and stress compared to the control group. Interestingly, when older adults combined psilocybin with lion’s mane mushrooms and niacin, they showed better improvements in motor control and speed. The effects were fairly consistent across different ages and genders, suggesting psilocybin microdosing may have real benefits for mental health.

Biological markers of treatment response to serotonergic psychedelic therapies: a systematic review

This review examines how scientists can predict which patients will benefit most from psychedelic-assisted therapy for depression by measuring biological markers in the brain and blood. Researchers found that certain brain changes and protein levels—particularly involving the amygdala, specific brain regions, and inflammation markers—appear linked to treatment success. While the current studies are small, they suggest that measuring these biological markers could eventually help doctors personalize psychedelic treatments for depression.

A review of the neuroscience of religion: an overview of the field, its limitations, and future interventions

This review examines how neuroscience studies the brain’s role in religious experiences and behaviors. While current brain imaging technology has revealed connections between specific brain regions and religious practices like prayer and meditation, these technologies limit what researchers can study because they require people to stay still. The authors suggest that newer technologies like functional near-infrared spectroscopy could allow scientists to study the full range of religious behaviors, including movement-based rituals that are important to many faiths.

CORRECTION: Efficacy of psilocybin for treating symptoms of depression: systematic review and meta-analysis

A major research study examining psilocybin’s effectiveness for treating depression has been corrected due to mathematical and data handling errors. The researchers fixed these issues by recalculating statistics and removing duplicate data from their analysis. While the main conclusions remained similar after correction, the authors emphasize this research is still preliminary and should lead to further study before clinical use.

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

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.

Analysis of Psilocybin-Assisted Therapy in Medicine: A Narrative Review

This review examines how psilocybin, the active compound in magic mushrooms, may help treat difficult-to-treat conditions like smoking addiction, alcohol dependence, and depression. Clinical trials show psilocybin-assisted therapy achieves better smoking cessation rates (80%) than standard medications and reduces depression symptoms as effectively as common antidepressants. The treatment works differently than daily medications, requiring only a few supervised doses weeks apart, potentially offering a new option for millions of people.
