The percentage of the population who are elderly will significantly increase over the next decade due to the aging of the baby-boom generation, putting additional stress on healthcare. The elderly are at higher risk for many disorders, especially cardiac-related problems and diminishing mental capacity. The impact will be felt in various domains, including additional pressures on existing infrastructure and increasing per capita costs for medical care. A potential approach to alleviate these problems is the implementation of home healthcare using new technologies. With remote interventions, the patient can remain at home, not only reducing costs but also benefiting from a familiar environment and support of family members. Methods are outlined that can contribute to the delivery of home healthcare in the areas of monitoring and support using intelligent agent methodologies. The methods are illustrated in two distinct applications: support and intervention for patients with dementia and remote monitoring of cardiac conditions. The methods outlined can also be adapted for use in other areas.
