My mother had psychiatric problems since the last 25 years (bipolar disease). We took treatment for some 8 years and stopped. Two months back we started treatment under a neuropsychiatrist. He started my mother on Clonazepam, Olanzapine and Valproate. She has been having memory problems and intense daytime drowsiness since then. An MRI taken a month back revealed dementia. Is this a coincidence that the symptoms started after the medicines? Or is it that the medicines have precipitated dementia? Can anyone here in anyway relate to this situation?
