Study summary

Alzheimer's disease (AD) is the main cause of dementia. At present, AD is incurable. Cholinesterase inhibitors, especially donepezil, are the first choice for mild and moderate AD. Sodium oligomannate (GV-971) is a marine-derived oligosaccharide. It is proposed that it can reconstitute the gut microbiota, and inhibit neuroinflammation in the brain as observed in animal models. It reduces Aβ deposition in the brain of Aβ-transgenic mice. The reduction in both Aβ deposition and neuroinflammation may synergistically contribute to the improvement of cognitive impairment and delay the progress of the disease. The State Food and Drug Administration of China (SFDA) approved it for the treatment of mild to moderate AD in 2019. Due to the different mechanism of cholinesterase inhibitor and GV-971, theoretically, they may synergistically improve cognitive function and delay disease progression. They are also used in patients with AD, but there is a lack of data on their effectiveness and safety. Therefore, the purpose of this observational study is to compare the efficacy and safety of donepezil and GV-971 monotherapy and combination therapy in patients with mild and moderate AD, which is of great significance for guiding the treatment of mild and moderate AD.

  • memory loss for at least 12 months, with a tendency of progressive deterioration;
  • brain magnetic resonance imaging(MRI) scan suggesting a significant possibility of AD ;
  • no obvious physical signs during nervous system examination;
  • stable and reliable caregivers,
  • elementary school or higher education level
  • signed an informed consent form
