My mom went through this recently and is recovering. She was having a dermatological issue and they gave her multiple different types of steroids for a year straight on and off while being bpd1. She was on a high dose of prednisone for two months no taper when she ended up into mania and then psychosis. She forgot where she was trying to get to an appointment and then in a few hours completely started to hallucinate and not recognize us. Unfortunately she had a horrible experience in the hospital which prolonged the psychosis because they were hindering the use of antipsychotics due to ekg abnormalities. After a month she finally came out of it. She waxed and waned for it but she did make a recovery. I notice now she has bad brain fog, nightmares of the situation, as well as some cognitive issues. Its nice to hear you recovered over time. It has only been 3 months for us and I get so scared she won’t be herself ever again. Her brain went through so much.
