Brain Oxygenation

Adequate blood pressure is described as important for delivering oxygen to the brain. Some people with dementia-like or brain fog symptoms may improve after blood pressure medications are removed because brain oxygenation improves. Excessive medication-driven blood pressure lowering is linked to brain fog, stupor, and dementia-like symptoms in some older adults. Concerns about medication-related cognitive dulling are framed as especially relevant in retirement homes and assisted living facilities.
