Obesity increases dementia risk: Winner of stupid medical article of the month

BBC NEWS | Health | Obesity increases dementia risk

I have a bad feeling this news story actually reflects the article. I think it's extraordinarily unlikely that obesity causes dementia; it will be very, very hard to extract a dementia/obesity relationship from obesity/IQ/wealth and IQ/dementia relationships. I'd be astounded if the authors were able to control for an obesity/IQ correlation.
