«If depressive symptoms were really a risk factor for dementia, if they caused dementia, then we’d see alliances throughout the follow-up. It wouldn’t just be confined to the end of the follow-up.
“What we can say with aplomb is that it doesn’t look as if depressive symptoms are a cause of dementia.»
