Complications

Memory and language loss, impaired judgment and other cognitive changes caused by Alzheimer's can complicate treatment for other health conditions. A person with Alzheimer's disease may not be able to:

• Communicate that he or she is experiencing pain
• Explain symptoms of another illness
• Follow a prescribed treatment plan
• Explain medication side effects

As Alzheimer's disease progresses to its last stages, brain changes begin to affect physical functions, such as swallowing, balance, and bowel and bladder control. These effects can increase vulnerability to additional health problems such as:

• Inhaling food or liquid into the lungs (aspiration)
• Flu, pneumonia and other infections
• Falls
• Fractures
• Bedsores
• Malnutrition or dehydration
• Constipation or diarrhea
• Dental problems such as mouth sores or tooth decay
