As many as 5 million Americans suffer from Alzheimer’s disease, the most frequent cause of irreversible dementia in adults. Many times it falls on those closest to the afflicted person to provide care when confusion sets in. In his book, “The 36-Hour Day,” now in its 5th edition from Johns Hopkins University Press, Dr. Peter V. Rabins breaks care-giving into simple steps to help those faced with caring for a loved one with dementia. The book, originally published in 1981, was the first of its kind and is considered the definitive guide to caring for people with dementia.
