Having Alzheimer disease or caring for a person with the condition may be a challenge. You can ease the stress of illness by seeking support through Alzheimer disease resources. Sharing with others who have common experiences and problems can help you not feel alone.
How quickly Alzheimer disease gets worse is different for each person. If Alzheimer disease develops quickly, it is more likely to worsen quickly.
People with Alzheimer disease often die earlier than normal, although a person may live anywhere from 3 to 20 years after diagnosis.
Families will likely need to plan for their loved one's future care.
The final phase of the disease may last from a few months to several years. During that time, the person becomes totally disabled. Death usually occurs from an infection or organ failure.
