I have a professional position which requires concentration, good decision making, excellent writing and speaking skills and ability to problem solve WITH LIMITED SUPERVISION. I HAVE A MASTERS DEGREE AND HAVE ALWAYS DONE WELL. However, my boss recently has been noting that I am making mistakes, I am more uncertain with clients and my memory and cognition seems off. I take levothyroxine and effexor, topomax . I have history of migraines and take zomig probably about 5 times amonth. Should I have cognitive testing of some sort? Others have noticed limited problems of this sort as I have also but think it's due to my age and stress.
