Experts warn that the growing number of dementia cases may become the social problem of this century. The World Alzheimer Report predicts that the burden placed on social resources by cases of dementia will continue to grow as the number of cases escalates. A reason behind the growing number of people suffering from dementia is due to an increase in life expectancy, with more people living into their eighties and nineties that than ever before. In addition to the increasing number of cases, a difference in how differing European countries care for patients with Alzheimer’s has also been found. The World Alzheimer report noted that in counties with higher income, patients are more likely to be looked after by professional healthcare workers, than by family members themselves.
