Turmeric is helpful for preventing and treating alzheimers.

Yeah, I heard of that before but I didn't know to what extent.

How young can people develop Alzheimer? I know its for older individuals, but are there any cases of those who aren't in that age bracket getting it?

I would try to occupy their thoughts with their good memories and steer them away from the bad ones. If they have forgotten someone has died then just change the subject to some other good memory.

That seems like a good idea.
Although it is worth acknowledging that it won't be an easy task.
