Various recent studies have linked the following conditions to an increased risk of dementia:
- Rosacea in older patients (American Neurological Ass’n.),
- late-life (age 55+) depression lasting over three years (Rotterdam study),
- an out-of-control immune system—common to AD, Parkinson’s, and Huntington’s (Univ. of Adelaide),
- and long-term use of Warfarin in patients under age 70 with atrial fibrillation (Salt Lake City study).
In addition, intra-cerebral hemorrhage was found to lead to dementia within four years in 1/3 of subjects (Lancet Neurology).
As a comparison, the George Institute for Global Health in a review of over 4 million records during a 7-year period found that patients between the ages of 30 and 50 with high blood pressure had a 62% increased risk of dementia, versus a 26% higher risk of dementia at ages 51-70.
