But this one from June 2019 came to the opposite conclusion:
Blood pressure and risk of dementia and its subtypes: A historical cohort study with long-term follow up in 2.6 million people June 2019
In the short-term, elevated BP is linked to a reduced risk of dementia, possibly due to reverse causation.

Researchers
conducted this systematic review and meta-analysis to explore if there
was a connection between blood pressure lowering and dementia or
cognitive impairment. They included 12 trials with 92,135 candidates
[mean (SD) age was 69 (5.4) years] for the primary outcome measure. A
significant link was seen between blood pressure reduction with
antihypertensive agents and lower risk of dementia or cognitive
impairment vs control, as seen in 7.0% vs 7.5% of patients over a mean
trial follow-up of 4.1 years. Findings suggested that there may be a lower risk of dementia or cognitive impairment associated with lower
blood pressure.
