Reishi mushroom (Ganoderma lucidum), known as "Lingzhi" in Traditional Chinese Medicine (TCM), has a long history of use for promoting longevity, vitality, and general cognitive health. In traditional medicine systems, reishi is often recommended for its supposed ability to calm the mind, improve memory, and support brain function. However, direct references to its use specifically for treating or supporting dementia are limited and are mostly extrapolated from its general reputation as a "tonic" for aging and cognitive decline.

Scientific evidence for reishi's efficacy in dementia is limited. Preliminary in vitro and animal studies suggest that certain compounds in reishi, such as polysaccharides and triterpenoids, may have neuroprotective effects, anti-inflammatory properties, and the potential to reduce oxidative stress—all factors implicated in neurodegenerative diseases like Alzheimer's. However, these findings have not been robustly validated in human clinical trials. Only a handful of small studies and reviews mention possible cognitive benefits, but none provide strong clinical evidence for reishi as a treatment or significant support for dementia.

In summary, the use of reishi mushroom for dementia is grounded more in traditional beliefs and practices than in strong scientific evidence. While laboratory research hints at possible benefits, there is currently insufficient clinical data to recommend its use for dementia beyond its traditional context.
