Can Medicinal Mushrooms Provide Improvements in Human Cognitive Abilities?

Summary

Hericium erinaceus (Lion’s Mane) is a medicinal mushroom with a long history of use in traditional healing. Modern research highlights its potential benefits for the brain and nervous system, including improvements in depression, anxiety, and cognitive performance.

A 12-week study by Saitsu et al. (2019) investigated the effects of Lion’s Mane on cognitive function in healthy adults over the age of 50. Participants were divided into two groups: one group consumed four daily supplements containing Lion’s Mane powder, while the other received a placebo.

Cognitive performance was evaluated using three tests:

  • Mini-Mental State Examination (MMSE) for overall cognitive function
  • Benton Visual Retention Test for visual memory and recognition
  • Standard Verbal Paired-Associate Learning Test (S-PA) for short-term memory

Key Findings:

  • No significant differences were found between the groups in S-PA (short-term memory) or Benton test scores.
  • A significant improvement in MMSE scores was observed in the Lion’s Mane group compared to the placebo group.
  • This indicates enhanced cognitive abilities related to memory, language, calculation, and orientation in participants taking Lion’s Mane.

Mechanism:
The cognitive benefits of Lion’s Mane are linked to compounds called hericenones, which stimulate the production of Nerve Growth Factor (NGF). NGF plays a critical role in maintaining and supporting neurons in the central nervous system and may help protect against age-related cognitive decline and neurological conditions like dementia.

Conclusion:
Supplementation with Lion’s Mane may support cognitive health in older adults, particularly by improving general cognitive function. Its neuroprotective properties suggest potential value in both maintaining brain health and addressing early neurological challenges.

 Mental Health Professionals Report Poor Literacy for Nutritional Medicine: International Survey Summary :  A 2021 international online survey by Mörkl et al. assessed nutritional literacy among mental health professionals (MHPs) across 52 countries. The sample included psychologists, psychiatrists, psychotherapists, and professionals in training, with most participants based in Europe and additional representation from Asia, North America, Oceania, South America, and Africa.
