I am familiar with this information. My concern is chemo brain a precursor to dementia. Prior to chemo, my executive planning skills were excellent, rarely had word retrieval deficits, and my short term memory was equivalent (or better than a 20 year old). I have recovered minimally from chemo brain. My general practitioner does not believe there is chemo brain. Any suggestions how to successfully improve cognitive skills?
