Abstract

The invention discloses the application of hederagenin or the medical salt thereof in the preparation of medicine for resisting senile dementia, cranial nerve damage and aging. According to the invention, the hederagenin or the medical salt thereof is used for treating the diseases, the curative effect is excellent, the side effect is small, the security is high, and a novel selection is provided for treating senile cerebral diseases.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to the application of helexin or a pharmaceutically acceptable salt thereof as an active ingredient in the preparation of anti-senile dementia, anti-cranial nerve damage and anti-aging medicines. Background technique [0002] Senile dementia, also known as Alzheimer's disease, is a primary degenerative brain degenerative disease of unknown etiology. Most of the onsets are in old age, the onset is insidious, the course of the disease is slow and irreversible, and the main clinical manifestation is intellectual impairment. The main pathological changes were diffuse atrophy of the cortex, widening of the sulci, enlarged ventricles, a large number of neurons, senile plaques, neurofibrillary knots and other lesions, and the content of choline acetylase and acetylcholine was significantly reduced. The onset before the age of 65 is formerly known as presenile dementia, or Al...
