A "transient ischemic attack" (mini-stroke) happens when there's a temporary drop in the blood supply, depriving the brain of oxygen. My father had low-to-normal blood pressure so I doubt it was caused by "increased pressure". And it seems that a clot would have had longer lasting effects. There was no noticeable after effect from his strokes, other than loss of smell that was noticed sometime later. Also, an MRI showed that he had absolutely no coronary artery disease.
I said he had a "few" mini-strokes but I was talking about the ones that I was aware of. He possibly could have had many more during the night, when his blood pressure could have been too low, and not been aware of them.

Alzheimers is caused by plaque building up in the brain tissue causing the synapsis not to fire correctly.

Yes, but what causes the plaque to begin building up in the first place? I have read that one of the causes could be a lack of oxygen to the brain. And that's exactly what I described above with a transient ischemic attack.
