A well-known fact about Alzheimer’s disease: one may have been diagnosed with Alzheimer’s, however, the signs and symptoms were there way before its diagnosis. I recall a neighbor’s brother that had his diagnosis at age 45. His doctor explained to the family that the disorder was there 10 years prior to that first visit and testing.
Now bio-markers started to develop new, more accurate blood testing so one can have a better and more detailed diagnosis. Biological markers can oversee that there is an overproduction of proteins beta-amyloid and tau, which can translate to brain malfunctioning.
Today Alzheimer’s disease testing is based on symptoms, patients, and family’s accounts, as well as memory testing to eliminate other diseases. For early stages, there is a big association with aging, making diagnosis very difficult if not impossible.
