Yes, there is a connection between concussion and BP. It can be due to the over-stimulation causing a fight or flight action or it can be an injury to the adrenal system causing an adrenal fight or flight reaction from very simple triggers like a startle.

I believe every patient who presents with PCS symptoms and has incidents of high BP should be trained about when to use an emergency supply of BP meds. I know too many people who have had very upsetting and dangerous situations due to these BP spikes. They can be deadly. Strokes and heart attacks.
