Making sure an Alzheimer’s patient receives the proper nutrition can be difficult. Often the person may not be able to sense or identify hunger or fullness, or feeling thirsty. As the disease progresses, the person may not understand the timing of meals, the difference between breakfast, lunch or dinner, and may need coaching in using utensils, chewing and swallowing food. You can assist the person by gently moving his or her chin to remind them to chew, and by lightly stroking the throat to remind the person to swallow. You may want to serve mashed or steamed vegetables, bite-sized pieces of meat, or put food into a food processor before serving. Be consistent and feed the person in the same area and at the same time at every meal.
