A key feature of Alzheimer’s disease is memory loss and losing one’s ability to think and make decisions (also called “cognitive ability”). Those changes can begin slowly, during a phase called “mild cognitive impairment” (or MCI). A variety of diseases can cause MCI, but the most common is Alzheimer’s disease.
