To the Editor: I practiced as a family physician & geriatrician from 1982 until my retirement in 2023, getting to know so many great people in the St. Cloud area. One of the biggest challenges my patients, their families and I faced was working through whether a loved one's behaviors could be a manifestation of Alzheimer's Disease. Even by 2023, there were no blood tests to aid in diagnosing Alzheimer's - only invasive and expensive procedures, like spinal taps and PET scans.
