From the writer of “My Demented Mom” blog, who writes about a fact that enrages me about victims of Alzheimer’s and related dementias: the mass abandonment of friends and family unwilling or too scared to see it through. Yes, perhaps the funeral is the easy part. Face it: dementia does and will happen to people you love, maybe even yourself. Fear will not prevent it from happening. Bravery will help you create a fulfilling experience despite the slow deterioration of one’s memory, faculties and personhood.
