Seizure and Brain Bleed

My 61-year-old, otherwise healthy, husband had a major seizure at 4:am Tuesday, think Grand Mal. This was the first time anything like this has happened, very frightening. Greg was rushed to our local hospital and released withing 4 hours. He had a CAT scan and it looks like he has a small brain bleed. Greg's neuro-onc didn't seem overly concerned. She has him back on Keppra 750mg twice a day. His short-term memory is even shorter if that's possible. His walk is even more hesitant.  We're waiting for the results of the second CAT scan, taken yesterday morning. We're back at UCLA next Wednesday for his routine MRI, blood and visit with neuro-onc. Has anyone had a similar experience? What does it mean to have a brain bleed, even a minor one? Do you recover from that or is the "new normal" reset?
Newest response from Greg's neuro-onc: "I don't think so.  These symptoms are quite typical of a bleed but as long as there is no worsening of the bleed, which sounds like there's not, he'll get better in about 3-6 months.  But he may feel better if we give a short burst of steroids for 4-5 days, 4 mg twice a day, before going back down to 4 mg."
Additional question: About a month ago, we stopped (cold turkey) almost all complementary meds, including chemo to give Greg a break. We also stopped cbd-thc sub-lingual spray. He continued to take curcumin+, metformin and just a couple of other meds but not the 25+ vitamins/supplements that have been part of his cocktail since September. Could that have something to do with the seizure/brain bleed?
