I have not experienced any of the memory or higher thought process issues that you describe - yet.
The most significant long term effects that I suffer with have to do with my reconstruction and the aftermath of the radiation - contracture and scar tissue discomfort. But even that is helped by the stretching. I also had some signicicant nerve damage from the axillary node dissection - sensation on my right side has really not returned. That and a little lymphodemia (I use a compression sleeve when I travel on planes).
But life is good - all worth it to be here :) I am able to do everything I ever did - just not as painless as it used to be - but very liveable....
Be Well
I have been on Arimidex for just over 3 years. I have had minimal obvious side effects, but some tough not so obvious side effects. It seems the longer I am on it, the side effects have been creeping in. I now have trigger thumb, hands are stiff. Had a bad fall in October, landing on my back and causing compression fractures in several vertebrae. I believe the anastrzole is complicating my recovery. Struggle with higher thought processes and memory issues.
However, considering the alternatives.....the AI has not been so bad. I did not have to have chemo or rads.....so if dealing with some bothersome side effects of an AI is all I have to do to help me remain NED....so be it!
Thanks for sharing your experience with Arimidex.
Sometimes the AIs get such a bad rep that people are afraid to even give them a try, to see if they can tolerate them.
Best wishes for continued good quality of life, and NED (no evidence of disease)!
