I admire your courage in sharing that scary information. Serial neuropshyc evaluations certainly are going to be helpful in your evaluation and follow-up. My wife had neuropsychological testing 7 years ago, which was consistent with MCI and only had one followup evaluation which confirmed the diagnosis and revealed no progression (but was only 6 months later). In those 7 years I have seen her transition to what I might describe as late MCI vs early dementia. Interestingly, her MMSE (mini mental status examination) which is used as a "rough" screen for dementia, has remained near normal all this time. All cognitive impairment is not the same.
