Silibinin ameliorates STZ-induced impairment of memory and learning by up- regulating insulin signaling pathway and attenuating apoptosis

Alzheimer's disease (AD) is a neurodegenerative disease, mainly characterized by cognitive dysfunction and memory impairment. Due to its pathological similarities to type 2 diabetes mellitus (T2DM), such as β-amyloid deposition, oxidative stress, inflammation, disordered glucose metabolism, impaired signaling pathways of insulin and insulin-like growth factor-1 (IGF-1), we speculate that AD is another form of brain diabetes.
