Brief Summary
Alzheimer's disease (AD) is a common neurodegenerative disease characterized by progressive cognitive impairment and memory impairment, and is also a major cause of global dementia, characterized by progressive decline in memory and daily living behavior. The incidence rate of AD increases with age. The prevalence rate of AD among men over 65 years old in China is 3.4%, and that of women is 7.7%, with a total prevalence rate of 5.9%. Among them, people over 65 years old can live for an average of 4 to 8 years after being diagnosed with Alzheimer's disease. According to statistics, there were approximately 5.98 million AD patients in China in 2005, reaching 10.2 million in 2020 and 22.5 million by 2040, making it the largest country with AD. At present, the treatment of AD is mostly limited to drug therapy, including Acetylcholine enzyme inhibitor, N-methyl-D-aspartate receptor antagonist and brain cell metabolism promoter. Although there are many types of drugs, their efficacy is not satisfactory, as they not only cannot effectively prevent and cure AD, but also cannot slow down the progression of AD. Regarding the surgical treatment of AD, neuromodulatory surgery, especially DBS (Deep Brain Electrical Stimulation), involves implanting stimulation electrodes into deep neural nuclei in the brain and performing electrical stimulation to change the excitability of the corresponding nuclei or neural circuits, and has been included in alternative treatment plans. In the past 20 years, DBS technology has been continuously explored for the treatment of AD, but an increasing number of clinical trials have shown that there is no effective target for AD-DBS. Therefore, there is an urgent need for new treatment methods to improve the current treatment status.
