High-dose psilocybin briefly revives function in advanced Alzheimer's: a case study

A published Frontiers in Neuroscience case report describes an 80-year-old woman with advanced Alzheimer's who temporarily regained urinary continence, walking ability, self-care, and conversational capacity after a single five-gram dose of psilocybin-containing mushrooms (with a follow-up three-gram session showing continued improved verbal expression). While the improvements spanned multiple domains and persisted for weeks, researchers caution that this is a single observational case without controls or standardized testing, and not evidence of a cure. The findings suggest dormant brain-network capacities may be temporarily re-engaged by psychedelic-induced neuroplasticity, highlighting the need for formal, controlled trials and safety assessments, particularly in vulnerable older adults; ongoing studies like UC Berkeley's PLASTICITY aim to explore aging brains and neuroplasticity with psychedelics.
