Must take all the tests. Only partial indications got my mom’s MD to treat it as early onset Alzheimer’s: Research has recorded slight betterments after 6 months of Aricept (Donepezil) treatment. My mom shocked the system with total recovery after 2, in spite of Hippocampus atrophy.

Most clear indicator was lowered Abeta42, but both Tau and P-tau values were normal. All else was inconclusive, but some cognitive tests were predominantly worrying for about a year. Now she aced them all.
