Alzheimer's is the most common cause of dementia, a general term for memory loss and other cognitive abilities. People with dementia generally demand on high level of care, most of which is not formally provided, that is family care. Due to the demands of everyday life, family members are no longer able to take care of the people with dementia, which is why the demand for formal types of care is increased. Palliative care is a comprehensive type of care for people suffering from incurable disease and their family members. Ethics has an important role in the context of decision making and planning when providing palliative care. Going from the early to the late stages of the illness, the verbal communication becomes scarce and later disappears completely. Person with AD is left with non-verbal communication or "body language" that his environment learns to understand and recognize. Social work with persons with dementia and their family caregivers contributes a social perspective to solving the multidimensional problems of persons with dementia and their caregivers.
