Especially in old age, it is common to become more forgetful and to struggle to remember important things. However, mental fitness can be practiced and improved by both young and old together. This applies to healthy individuals as well as to those suffering from Alzheimer’s or other forms of dementia. The training book "Take Time for Grandma and Grandpa" contains memory exercises at all difficulty levels for older adults and their relatives. Through short daily practice sessions, memory performance, concentration, and attention skills are enhanced. Word fluency and general knowledge are also trained. The exercises are suitable for individuals already diagnosed with Alzheimer’s. The authors, Croy and Gatterer, are psychotherapists who have incorporated their professional and personal experiences with cognitive training for older adults into this book.
