Deep dives
Redefining Alzheimer's Disease
Alzheimer's disease is identified as a distinct biological process rather than being synonymous with dementia. The prevailing view is that Alzheimer's should be defined by the presence of specific brain pathology, such as amyloid plaques and tau tangles, that can occur in asymptomatic individuals. This perspective emphasizes that Alzheimer's disease begins with biological changes in the brain many years before clinical symptoms become apparent. Recognizing Alzheimer's as a disease continuum allows for better understanding and treatment approaches that target the disease before significant cognitive decline occurs.
