Quality >> Quantity.

Mum passed away peacefully in the middle of the night. I'm waiting for paperwork to be done.

"And the best you can hope for is to die in your sleep."

On the internet, I read that Dementia with Lewy bodies has a mean survival time of 6 years from the onset of symptoms. Mum first became confused in mid-July 2007, so it's been just under 6 years. Does this mean that all of the supplements I gave her were worthless. Hell, no!

As mentioned in Look after your brain., mum's MMSE score increased from 14 to 26 out of 30 after taking medication and supplements. The medication gave a 3 point increase in MMSE score on average, so the rest of the increase in MMSE score was probably due to the supplements, which had no undesirable side-effects.

On Christmas day 2008, mum was capable of preparing Brussels sprouts for cooking, though she got the knives, forks & spoons mixed up when she tried to lay the table. Here's her final Christmas at home. Roast duck with all of the trimmings. Om, nom, nom!

Mum's last Christmas at home.

In conclusion, I believe that quality of life trumps quantity of life, so supplementation for the win.
