Again, from The Nun Study, some general sense of what might change or not. Lower linguistic ability in early life predicts dementia and earlier death. Again, even a smaller set of cohorts, 74 nuns ages 74-97. And again they used the same autobiographies written at 30-60, a long time ago, to measure idea density and they looked at the ratio of the idea density to neurofibrillary tangle count. They found the idea of density related to the tangle counts but unrelated to any vascular changes that the individuals might have experienced before their death.
