Difficulties with memory and a variety of different cognitive abilities that are severe enough to impede everyday activities are caused by Alzheimer's disease, which is the most prevalent form of dementia. Currently, between 60 and 80 percent of all dementia cases are caused by Alzheimer's disease.
Symptoms of Alzheimer's
Our brains undergo changes as we grow older. Most of us will ultimately experience some delayed thinking as well as occasional difficulties remembering specific things in the future. Brain cells are believed to be deteriorating when we experience severe memory loss, disorientation, or other significant changes in the way in which our minds work.
​
Alzheimer's disease usually starts in the region of the brain that controls learning. As Alzheimer's disease progresses through the brain, more severe symptoms emerge, such as disorientation, mood, and behavior changes; growing confusion about events, time, and place; unwarranted suspicions about family, friends; serious memory problems and behavioral issues; and slurred speech, swallowing, and walking.
