Someone with advanced dementia may not be able to get around. This might start with difficulty walking and then ultimately result in becoming bedbound. Immobility could result in a blood clot which could lead to death. In this case, the clot was a result only of immobility, meaning dementia was the initial cause. Alternatively, a person with advanced dementia may have difficulty swallowing. This leads to aspirations that can ultimately result in pneumonia and later death. In both of these scenarios, dementia was the initial factor leading to the individual’s death- making it the person’s true cause of death.
