Both my 80-year-old parents are diagnosed with Mild Cognitive Impairment. They have become impulsive, disorganized, argumentative, and forgetful. They can no longer maintain their train of thought or follow the thread of a conversation. They regularly forget to take their medicines (even though I visit weekly to dispense into pill containers) and they miss Dr appointments. They show very poor judgment and they're overwhelmed by making decisions or planning a task. And they have recently started to have trouble finding their way around familiar locations. My dad is in worse shape and was diagnosed with MCI about five years ago. He no longer knows what year it is or what city he is in. My mom's diagnosis was last year and doctors can't say whether it is truly an intermediate dementia stage, or caused by the stress of caring for my father. I'm 60 miles away. I call daily and make weekly visits to check on them and refill their pill containers. I have arranged for nursing and PT home visits, as well as placing a home health caregiver in their house 40 hours a week. But they fired the first caregiver and ran the second off. I'm nearing my wit's end. My question is about what I can expect as time passes. Does MCI always develop into full dementia? Will they get Alzheimer's? Is it possible for them to get better? (They are both on Namenda and Donepezil.) I need to know what to expect or at least what to prepare for. Thanks for whatever advice you can provide.
