Ovary-Sparing Hysterectomy followed by neurological issues

On May 27th, I will be 1 year post-hysterectomy. As of January '26, I have been experiencing seizures, headaches, shakiness, low blood pressure, and imbalance issues. I did what felt like a lot of research about hysterectomies prior, but now seeing studies of how much the Uterus actually is in connection with the brain.
Has anyone experienced cognitive changes following their hysterectomy?
