My 82 yr old mother was prescribed Synthroid last May after tests on her carotid artery showed a problem with her thyroid (she had no symptoms). In June, my father started calling me and telling me how strange she was acting. So I called the Dr., and he said she was getting dementia, so put her on Aricept. Then she started getting depressed, not doing all her favorite things, not driving, etc. I called Dr. again and he put her on an antidepressant. I now know that this whole situation was caused by the Synthroid. It is so obvious. I am taking her off it for a few days to see how she acts. I sympathize with everyone who posted.
