It’s not completely clear what causes Alzheimer’s disease but from what we can tell, no one is completely safe from the disease. Even very famous people succumb to it despite having access to the best resources and care. Early diagnosis of Alzheimer's disease is important for several reasons. First, it allows for earlier intervention and treatment, which can help slow the progression of the disease and improve quality of life for the individual. Early diagnosis also allows for better planning for the future, including financial and legal planning, and can facilitate discussions about end-of-life care. Additionally, early diagnosis can help with the identification and management of other potential contributing factors, such as depression or other medical conditions. Furthermore, early diagnosis can help people with Alzheimer's disease and their families access resources and support, such as support groups and care facilities.
