[When Philosophy Sheds Light on Alzheimer's Disease].

This article examines our relationship with the patient through three classic problems of philosophy: the relationship between mind and body, the voluntary or involuntary nature of our actions, and finally what constitutes our identity. All three determine at once who we are, our responsibility and our relationship with others. Yet these problems, often addressed in school essays, are not confined to an academic setting but also offer a way to enrich our relationships with others.
