Alzheimer's Disease | Memantine on Aggression and Agitation of Alzheimer's Disease (AD)

Alzheimer's Disease research study

What is the primary objective of this study?

Alzheimer's disease (AD), is associated with behavioral disturbances in approximately 50% of AD patients in Beijing. Agitation, and aggression specifically, is considered the most serious noncognitive symptom experienced in patients with dementia. Memantine is a recognized treatment for Alzheimer's disease either alone or in combination with cholinesterase inhibitors. Its efficacy in vascular dementia is also established. Family members continue to play a central role in home care for the demented elderly in China. This proposal is to conduct a study in Beijing, China to investigate the efficacy and safety of Memantine in the treatment of agitation and aggression in AD patients. In addition, this proposal aims to explore the impact of memantine on caregiver burden of AD patients in Chinese culture.
