Abstract
Dementia is an acquired, chronic, progressive neurodegenerative disease with a terminal phase characterized by profound cognitive impairment with an inability to communicate verbally; functional dependence for basic activities of daily living; and the presence of other common medical problems, including eating problems, infections, and pain. A mean survival of ten years from its diagnosis is estimated. Establishing a prognosis in advanced stages is a challenge due to uncertainty regarding its progress and the onset of complications. Therefore, care and decision-making must be aimed at the patient's needs and care objectives more than the estimated life expectancy, taking into account the patient's and family members’ preferences.
