Alzheimer's disease has long been known as Alzheimer's disease, because Alzheimer's disease is predominantly older than 65 years old, and because Alzheimer's disease accounts for a similar proportion of Alzheimer's disease in Alzheimer's disease. Big. So many times, Alzheimer's disease has become synonymous with Alzheimer's disease. However, as far as the beginning of Alzheimer's disease is concerned, the academic community has always been inconsistent.

Their important research results are published in the famous journal "Acta Neuropathologica" in the field of neurology (2).
