Population aging causes the prevalence of hypertension to increase, which increases the incidence of dementia and leads to premature death. The simultaneous development of these two diseases accelerates the progression of dementia, leading to a reduction in the patient’s quality of life. This is difficult for caregivers, as it causes them to shoulder a greater burden and brings greater emotional stress, resulting in their wanting to end the care relationship or even neglect or abuse patients. In addition, their own mental and physical health is also severely affected, causing them to seek medical treatment themselves. In view of this problem, we propose a cloud-based physiological sound-controlled intelligent music and blood-pressure control system to assist family caregivers of dementia patients to reduce their burden as well as their stress. We interview family caregivers regarding the benefits of this system in assisting them and find that most caregivers find the system to be helpful.
