@turquoise-- I have lupus cerebritis too. I was diagnosed three years ago. I'm doing okay, certainly much better than when I was first diagnosed. A good treatment plan can help keep symptoms of lupus cerebritis under control or can at least help prevent further complications.
I too have similar symptoms like tingling and numbness. My neurological responses are poor. I have really bad reflexes, it takes a very long time for my body to respond. I have mental concentration issues and mild visual auras as well. When I was first diagnosed however, I was in a worse state with partial paralysis and seizures. So I'm thankful for how I am now.
I'm sure that with proper treatment your lupus cerebritis symptoms will lesson. Do you have a good doctor who has lost of experience with lupus?
