An 80-year-old woman with advanced Alzheimer's experienced a dramatic but temporary improvement after receiving psilocybin.
Reported improvements included speaking in full sentences, recalling memories, regaining bladder control, dressing herself, and engaging socially.
A follow-up dose was associated with further gains in verbal expression, humor, and mobility.
The findings come from a single-patient case study, meaning much more research is needed before drawing broader conclusions.
