Brief Glimmer of Function: Psilocybin Sparks Temporary Gains in an Alzheimer’s Case

A case report describes an elderly Japanese-American woman with advanced Alzheimer’s who ingested psilocybin mushrooms in two supervised sessions and, within hours to weeks, showed improved alertness, memory recall, mobility and independence; however, the observations come from a single patient with no biomarkers, controls, or standardized testing, so they cannot prove that psilocybin reverses Alzheimer’s or guide therapy. The report suggests possible temporary changes in brain networks and neuroplasticity but remains unproven, and safety concerns and the lack of controlled data mean this should not inform self-treatment outside supervised research.
