Alzheimer's Disease is the most common form of dementia, accounting for at least 50% of all diagnosed cases. It is distinct from the normal aging process. Alzheimer's Disease progresses from forgetfulness to confusion to the point where the person cannot be left alone. A diagnosis of Alzheimer's is frightening. Do not let fear keep you from seeking help. The best offense for families who must cope with this diagnosis is to investigate, read and question everything they can in order to better understand the possible causes, treatment and progression of the disease.
