> The new study shows that depression leads to Alzheimer's and not vice versa as hitherto thought.

it does no such thing.

Thank you for this. I would have naively accepted the article. Family members suffer from AD so this is particularly interesting for me. How can they pervert the nature of the findings so drastically?

I think it's pretty clear that the reporter just flat out misunderstood both the paper and the researchers. They even supply this quote: "Loss of memory and depression are two sides of the same coin," says D'Amelio.

Now, this is not an area that I'm terribly familiar with, so I also had trouble understanding the paper. I get the impression that the disease (in the mouse model) attacks the dopamine system first, so this can be an early warning that Alzheimer's may develop. Is that a correct interpretation?
