Cognitive decline has become such a pervasive issue in modern society; it has become normalized across the political spectrum. Some of today's government officials show serious cognitive decline, and even the de facto President of the United States routinely stumbles around in a stupor, taking cues from handlers and mumbling incoherently at times.

Cognitive decline is a serious health issue worldwide, but in many cases, there are ways to reverse the damage, prevent the death of neurons and regenerate neuronal pathways. Lion's mane mushroom is an important medicinal food that can promote the biosynthesis of nerve growth factor and effectively combat dementia.

Lion's mane mushroom promotes the biosynthesis of nerve growth factor
A study published in Mycology finds that Lion's mane mushroom (Hericium erinaceus) synthesizes two very important compounds for nerve growth – Hericenones and erinacines. These compounds are derived from the fruiting body and mycelium of the mushroom. Both compounds promote the biosynthesis of nerve growth factor (NGF) and therefore have value in the prevention and treatment of dementia.

Scientists have isolated two erinacine derivatives and two erinacine diterpenoids (Cyatha-3 and 12-diene with isomer) that promote NGF. Scientists have also demonstrated NGF-stimulating activity from three other compounds in Lion's mane - Hericenones C, D and E. One of the compounds, 3-Hydroxyhericenone F, showed protective activity against endoplasmic reticulum stress-dependent Neuro2a cell death.
