Alzheimer’s disease (AD), also known as Alzheimer disease, accounts for 60% to 70% of cases of dementia. It is a chronic neurodegenerative disease that usually starts slowly and gets worse over time. The most common early symptom is difficulty in remembering recent events (short-term memory loss). As the disease advances, symptoms include problems with language, disorientation (including easily getting lost), mood swings, loss of motivation, not managing self care and behavioral. As a person’s condition declines, they often withdraw from family and society. Gradually, bodily functions are lost, ultimately leading to death. Although the speed of progression can vary, the average life expectancy following diagnosis is three to nine years.
In the present book, ten typical literatures about Alzheimer’s disease published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on medical science, neurology, genetics, ect. We hope this book can demonstrate advances in Alzheimer’s disease as well as give references to the researchers, students and other related people.
