Abstract: Nervonic acid was first found in the nervous tissue of mammals and was named for it. In recent years，nervonic acid has been widely concerned by neurobiology and nutrition experts at home and abroad because of its unique role in nervous system development and disease prevention and treatment. Nervonic acid is the main component of human brain complex lipids. As a kind of ultra-long chain monouns-aturated fatty acid，it is the core component of the myelin sheath of brain nerve cells，and has the function of repairing damaged brain nerve fibers and promotes neuron regeneration. The lack of nervonic acid in the human body can lead to insomnia，forgetfulness，brain atrophy，white matter disease and other neurological diseases，which can be effectively alleviated by supplementation of nervonic acid. In addition，nervonic acid can also improve metabolic abnorm-alities and cardiovascular and cerebrovascular diseases， and enhance immunity. Therefore，nervonic acid is of great significance to human health，and has aroused the research interest of a great number of medical workers. This article will review the application of nervoinc acid in the treatment of nervous system diseases at home and abroad，and make a summary of it.

Key words: nervonic acid, neurodegenerative diseases, demyelinating diseases of central nervous system, cerebrovascular diseases, unsaturated fatty acid
