Hi, The cause of your mother s symptoms can be a number of things. Certainly low pressure can cause fainting and disorientation. Whenever the blood pressure gets too low, our body responds by engaging the Flight or Fight response, releasing significant amount of epinephrine. This can causes vomiting and incontinence. However, I do share your concern about potential other causes, namely seizures. There are various types of seizures that can present this way and it is difficult to ascertain if this is the ongoing issue to not. She needs, for one thing, to have her blood pressure regimen loosened up somewhat. It is much safer to allow her blood pressure to run a little more of the higher side rather that push these medication doses higher and risk her falling and injuring herself. That is step one, namely speak to her physician and reduce the dosages of these medications if only temporarily. Next she needs evaluated for some sort of intracranial process, lab work, a CT scan of the head, and potentially an EEG to look specifically for seizures. A third consideration is to see if her heart is having periods of an irregular rhythm. If her heart rhythm is not in what is called the regular sinus rhythm then these symptoms also could result. An EKG and Echocardiogram definitely need to be completed. I share your concern and it does sound like there is more to this story. Please press her physician for medication reductions on the blood pressure regimen and also request a neurological work-up or even a referral to a neurologist. I am not sure if this was helpful or not, but please keep an eye on your mother! Take care. Hope I have answered your question. Let me know if I can assist you further.
