Alzheimer's Disease (cont.)
IN THIS ARTICLE
Memory loss is usually the first sign of Alzheimer's disease. Having some short-term memory loss in your 60s and 70s is common, but this doesn't mean it's Alzheimer's disease.
Compare these examples of normal memory problems and the types of memory problems that may be caused by Alzheimer's disease.
Alzheimer's disease also causes changes in thinking, behavior, and personality. Close family members and friends may first notice these symptoms, although the person may also realize that something is wrong.
Following are some of the symptoms of the different stages of Alzheimer's disease. They vary as the disease progresses. Talk to your doctor if a friend or family member has any of the signs.
Mild Alzheimer's disease
Usually, a person with mild Alzheimer's disease:
These symptoms often are more obvious when the person is in a new and unfamiliar place or situation.
Some people have memory loss called mild cognitive impairment. People with this condition are at risk for Alzheimer's disease or another type of dementia. But not all people with mild cognitive impairment progress to dementia.
Moderate Alzheimer's disease
With moderate Alzheimer's disease, a person typically:
Severe Alzheimer's disease
With severe Alzheimer's disease, a person usually:
Other conditions with similar symptoms
Early in the disease, Alzheimer's usually doesn't affect a person's fine motor skills (such as the ability to button or unbutton clothes or use utensils) or sense of touch. So a person who develops motor symptoms (such as weakness or shaking hands) or sensory symptoms (such as numbness) probably has a condition other than Alzheimer's disease. Conditions such as Parkinson's disease, for instance, may cause motor symptoms along with dementia.
Other conditions with symptoms similar to those of Alzheimer's disease may include:
