Hi! I also experience short term memory loss and poor concentration. I attribute it to meds and not sleeping well but when i met with a neurologist well known for RSD he said RSD/CRPS causes changes which include stm loss and decrease concentration. For me it has been scarey because i have left the stove on and much more. These things have worked and helped me- I have a timer in kitchen incase i turn anything on or plug anything in. I have a calendar which everyone writes on and i check it every morning to make sure i dont miss or forget something. I have a pill box which is filled once a week so i am sure i take/took my meds(I could never remember if i took them or not) this has really helped. momof4
