> We report the case of an octogenarian Japanese-American woman with a 10-year history of Alzheimer’s disease, including 5 years of marked hypofunction and predominantly monosyllabic speech.

> The patient received 5 g of orally administered psilocybin-containing mushrooms

> Approximately 19 h post-administration, spontaneous autobiographical speech emerged. Over subsequent days and weeks, functional improvements included restoration of urinary continence, improved ambulation, autonomous dressing, increased emotional responsiveness, sustained social interaction, contextual memory retrieval, preserved working memory for social context, and spontaneous conversational engagement.

This is exactly that, a treatment using psilocybin that was successful. It's not claiming to have developed a treatment protocol, the title is precise.
