 What if your loved one already has Alzheimer's? The Processed Apples Institute funded a study suggesting apple juice may help prevent Alzheimer's, but now they're back. After changing their name to the Apple Products Research and Education Council, they funded a new study in which instead of dripping apple juice on nerve cells in a Petri dish, they had 21 Alzheimer's patients drink a cup of apple juice every day for a month to see what would happen. It's in the lab, but does it work in the nursing home? After a month of apple juice, no changing cognitive performance or did-day functioning, but they did report improvements in mood and behavior. Less apathy, agitation, anxiety, depression, delusion did seem to hallucinate a bit more, though. But this is a tiny study, no placebo control. But hey, look, there's worse things doctors could give them than apple juice, though if I was going to repeat this study, I'd choose pomegranate or purple grape, though then one would miss out on funds from Big Apple.
