Severe Alzheimer's disease is characterized by almost total memory loss. The person in this last stage of Alzheimer's usually needs help with all of the basic activities of daily living. She will lose the ability to walk unassisted, and eventually even to sit up by herself. The body eventually forgets how to carry out the normal biological functions necessary to sustain life.
Activities for late stage Alzheimer's disease include music, especially familiar songs from the persons past, and those which provide sensory stimulation. Often, someone who has trouble putting a sentence together may sing a familiar song perfectly, start to finish. Focus also on sensory stimulation, particularly tactile stimulation. The Twiddle Muffs and our collection of aromatherapy animals are perfect to provice this tactile stimulation.
Even though communication skills are withering drastically at this point, watch for other cues. A smile or other body language can indicate that the music you are playing, the picture you are sharing, or the video you are watching together is bringing pleasure.
