My seizure-like symptoms (limb jerking, slurred speech, lack of coordination, brain fog, etc.) began post-menopause. I'm presently age 55, went through menopause at age 49, and actual limb jerking, etc. began around age 53. However, the rapid blood pressure extremes (100 points in either direction - spikes and falls) since age 44. It's been a very long, expensive, and difficult road, only to find myself back to square one.
