“so high blood pressure is associated with dementia risk particularly when you have it like before you know the 50s like so when you start when you get it in your you know before the 50s or you know midlife once you start to get high blood pressure in older age like 70 80. it's not as much associated with you know the the Alzheimer's disease and dementia risk so um it really does seem like cumulative exposure is the the key factor there”
