What are common physical complications associated with advanced Alzheimer's?

In advanced stages of Alzheimer's disease, individuals often experience significant physical complications due to the progression of the disease. One of the primary challenges is difficulty swallowing, known as dysphagia. This condition can lead to malnutrition and dehydration, as individuals may struggle to eat and drink effectively. As a result, the risk of aspiration—where food or liquids enter the airway—greatly increases, leading to respiratory infections such as pneumonia.

Moreover, individuals with advanced Alzheimer's may also experience limited mobility and overall decline in physical health, which can further contribute to the likelihood of infections. As the disease progresses, the immune response tends to weaken, making it harder for the body to fight off infections. Therefore, the association of difficulty swallowing and increased risk of infections is a significant aspect of the physical complications arising from advanced Alzheimer's disease.
