Yes definitely...unfortunately this is part of lupus. I have CNS vasculitis and had seizures for several months before they found out how to stop them and to treat my lupus with chemo. Guess even those who don't have lupus of the brain have concentration problems. It's really troublesome when I was trying to train for a new job.
Hope it gets better...I carry a sticky notepad around with me or program reminders into my phone with an alarm so I don't forget. Don't know if that will help!
