Alzheimer's disease affects the brain in multiple ways, and can cause eating problems. Mealtimes can be impacted by the person’s inability to chew and swallow. Alzheimer's can also affect taste and smell, so food may not be as appetizing anymore. Eating utensils might be confusing, and the person with Alzheimer’s might not know what to do with food that is placed in front of him. The person might put too much food in the mouth at once, eat too quickly, attempt to swallow without chewing, or try to eat inedible items.
