My cognitive function was rather severe - it was enough to be measurable by neuropsych testing - and caused the loss of my business, my career, and my PhD dissertation. For almost 2 years, I didn't even drive as I'd get disoriented within a block or 2 of the home I've lived in for 25 years.
I had improvements once the fatgiue was addressed, and more improvements since my lupus has "quieted". While I am probably 90-95% back to my pre-lupus normal, as Bill says, my memory and ability to learn has been permanently compromised.
My recommendations -- use all the tricks you can find to help supplement your memory, make sure your sleep and eating habits support heath, avoid stress as much as possible, and give yourself plenty of time to read and fully comprehend the material.
As Bill says, Life is good but different!
