This book is a sort of a more elaborate continuation of the first guide edited five years ago (in a small number of copies) of the guide "The Basics of Alzheimer's Disease." It tries to attract not only those being confronted with this endemic, which has spread throughout the entire humanity, the World Health Organization calling it "the medical terror of the 21st century," but also those who wish to be informed or learn about what can be done at this moment to stay away from this invisible enemy. The book is structured in 101 questions, the most frequent ones encountered in my medical practice in this field (over 15 years and a number of a few thousand patients), after being asked by relatives to publish it - even by the patients themselves eager to find solutions to their problems. The language used in this book is a very intelligible one for the reader, without affecting the scientific content of the information, but reducing this information to the very essence. Sometimes, the direct term "Alzheimer's" will be used, as is practiced nowadays, as well as in the scientific presentations in order to simplify the transmitted message.
