Do amyloid-beta plaques cause Alzheimer's disease?

Resolves to my credence in 2030.

ChatGPT summary of the debate:

"- Amyloid plaques are sticky clumps of protein that build up in the brains of people with Alzheimer's disease.

  • The scientific community has been divided on the role of amyloid plaques in Alzheimer's for many years.

  • Some researchers believe that amyloid plaques are the main cause of Alzheimer's and that removing them from the brain would cure the disease. This view is supported by studies that have shown that mice genetically engineered to produce less amyloid plaques do not develop Alzheimer's, and that drugs that reduce amyloid levels can slow down the progression of the disease in some people.

  • Others argue that amyloid plaques are a consequence of the disease rather than a cause, and that removing them would not cure Alzheimer's. They point to the fact that many people with high levels of amyloid plaques do not have Alzheimer's, and that some people with Alzheimer's have little or no amyloid in their brains.

  • There is also evidence to suggest that amyloid plaques might play a role in the spread of Alzheimer's from one brain region to another, but more research is needed to confirm this.

  • In recent years, the scientific community has shifted towards a more nuanced view of amyloid plaques, recognizing that they may play a role in the development and progression of Alzheimer's, but that the disease is likely caused by a complex interplay of genetic, environmental, and lifestyle factors.

  • More research is needed to fully understand the role of amyloid plaques in Alzheimer's and to develop effective treatments for the disease."
