The invention discloses application of cobra neurotoxin monomer molecules in treatment of senile dementia. The senile dementia, also known as Alzheimer disease, is a senile disease with progressive memory disorder, obstacle of judgment and reasoning ability as well as dyskinesia as main clinical features. Evidence shows that strong focal inflammatory responses exist in the brains of the patients with the senile dementia, and activated microglia and astrocytes exist near senile plaques; and the activated microglia and astrocytes can express a plurality of inflammatory cytokines, including interleukin-1[beta] (IL-1[beta]), tumor necrosisfactor-alpha (TNF-alpha) and the like.
