Probably a factor in a multi-factor answer.
Think of it this way, not only was lead gasoline banned, but over the last 30 years we have moved manufacturing jobs to Asia (which has not seen the decline in dementia that the west has).
Manufacturing exposes workers and the surrounding area to all kinds of dusts, chemicals, etc.
