Claudia H. Kawas, M.D., addresses Alzheimer's disease and related conditions in older adults, noting the challenge of accurate diagnosis and the resemblance of other brain conditions to Alzheimer's. She introduces "resistance" and "resilience," explaining how some individuals remain cognitively intact despite brain changes. Kawas suggests declining dementia risk due to improved vascular health management, emphasizing the complexity of cognitive decline and the need for further research.
