The tests to know the current level of your mind (memory etc.) are available with the doctors (neurologists & psychiatrists). You can visit one of them and they can assess you for those functions of brain. It is difficult to say whether the memory problems are due to Eptoin
or due to routine aging in your case. Memory problems are generally not seen with Eptoin. There are many medications available as substitute for it and your neurologist can advice if there is a need to change it. There are also medications available for memory problems.
