Abstract: The present invention relates to diagnosing, preventing, delaying or reverting the progression of pathologies associated with abnormal amyloid deposits, such as that exemplified by Alzheimer's disease (AD). More specifically, the method involves administration of specific molecules that function as Piezo agonists, such as Yoda1, Jedi1, 5 Jedi2, or functional analogs thereof, that are able to modulate microglial activation towards anti-inflammatory state and/or interfere with the formation of amyloidogenic peptides and/or increase their efflux from the central nervous system.

Abstract: This invention relates to a method for diagnosing a subject's increased risk of progressing to Alzheimer disease by measuring the concentration of a metabolite and comparing them to respective mean concentration of healthy subjects. According to the invention the increased risk of progressing to Alzheimer's disease by a subject with mild cognitive impairment can be diagnosed without invasive technology.
