@whs2026 Hello Bill. I was reading over your comments trying to understand your situation. May I ask what Mayo specialists have ruled out? You mentioned Parkinson’s, but also a concussion, so it makes me wonder if you had a neck injury or shoulder injury? I do know that a fainting episode can look like a seizure when the brain doesn’t get enough blood and oxygen supply because of dropping blood pressure. I once passed out during some painful neurological testing, and they sent me for an EEG to test my brain and a sleep study. I didn’t have seizures. I also have a condition called Thoracic Outlet Syndrome or TOS which is a compression of nerves and blood vessels in the shoulder. It causes tightness from the neck to the scapula. If I turn my head, the pulse diminishes in the base of my neck. Some patients can pass out from this lowered pulse that can affect circulation to the brain. Also, if the cervical spinal alignment is off, it can stretch the vertebral arteries that run inside the cervical vertebrae. That is also part of the blood supply for the brain. I was getting dizziness and some vertigo when my vertebrae were twisting due to muscle spasms. I was in need of spine surgery at the time for a bad disk. My experiences with these issues caused some similar symptoms and weakness when an episode of crashing blood pressure happened. For me that was a response to fear and not related to heart function. Fainting is a protective response if blood pressure is spiking and it’s meant to be a safety valve to release high blood pressure. That is something that has to be evaluated of course. Has anyone evaluated your cervical spine or tested you for thoracic outlet syndrome? Have they ruled out cardiovascular issues? What others details can you share?
