It would appear to be the other way around. Alzheimer's is one of the plagues of dying living in a earthen body of death described in Chapter12. the diminishing of hearing, seeing, smelling others e.t.c.
Ecclesiastes 9:4 For to him that is joined to all the living there is hope: for a living dog is better than a
dead lion.For the living know that they shall die: but the
dead know not any thing, neither have they any more a reward; for
the memory of them is forgotten. Also their love, and their hatred, and their envy,
is now perished; neither have they
any more a portion for ever in any thing that is done under the sun.
Not our memory of them is forgotten .
Its testimony in chapter 12 . Remember by acting in accordance to
Ecclesiastics 12
Remember now thy Creator in the days of thy youth, while the evil days come not, nor the years draw nigh, when thou shalt say, I have no pleasure in them; While the sun, or the light, or the moon, or the stars,
be not darkened, nor the
clouds return after the rain: In the day when
the keepers of the house shall tremble, and the strong men
shall bow themselves, and the grinders cease because they are few, and
those that
look out of the windows be darkened, And the doors shall be shut in the streets, when the sound of the grinding is low, and he shall rise up at the voice of the bird, and all the daughters of musick shall be brought low;
Also when they shall be afraid of that which is high, and fears shall be in the way, and the almond tree shall flourish, and the grasshopper shall be a burden, and
desire shall fail: because man goeth to his long home, and the mourners go about the streets:
Or ever the silver cord be loosed, or the golden bowl be broken, or the pitcher be broken at the fountain, or the wheel broken at the cistern. Then shall the
dust return to the
earth as
it was: and the
spirit shall return unto
God who gave
it.
