• The main characteristics of this disease are: memory loss; apraxia‐aphasia‐agnosia; personality changes; and symptoms affecting behavior such as aggressive behavior and disorientation. Alzheimer's engenders exceptional distress both in the informal caregiver network and in the organizations that produce services for those affected by the disease. Among the main causes of this distress we can mention: Alzheimer's disease damages the process of recognizing people, even relatives, and therefore can also damage one's feelings of gratitude toward caregivers, engendering, for example, difficulty in establishing and managing the relationship with the sufferer; the causes of Alzheimer's are still partly unknown, soliciting the fear of the disease's heritability; Alzheimer's has very diversified phases which entail the need to diversify the care and services offered.
