Is it possible 2 take donepezil for mci?

Yes but not recommen. Yes, you can take donepezil (or for that matter, anything) for mild cognitive impairment but doesn't mean you'll get any benefit. In fact, studies have demonstrated no benefit from taking donepezil (or any other acetylcholinesterase inhibitor or nmda receptor antagonist) prior to actually being diagnosed w/alzheimer's dementia. So don't waste your money. Focus on nutrition & exercise instead.
