A Review of Alzheimer’s Disease and Emerging Patient Support Systems

Alzheimer's disease (AD) is the main and most common source of brain ill health and neurocognitive disorders. Dementia accounts for 80% of AD cases. This disease is considered one of the biggest challenges facing social organizations and medical care providers at present, whether they are within these organizations or at home. The most worrying problems facing the world are the significant rise in the prevalence of dementia, especially for those over the age of 65, with no treatment for this disease. Consequently, healthcare costs have increased steadily, which puts a burden on healthcare systems and puts pressure on families. Researchers have estimated that by 2050, there would be 152 million individuals worldwide living with dementia. The cost of dementia care is expected to exceed $1 trillion. Therefore, it is important for these patients to try to do what they can do for themselves, such as going out without a company and taking medicine on time for as long as possible. The aim of this study is to assist Alzheimer's disease patients to slow cognitive degradation and reduce the burden of care and psychological pressure on families and caregivers. The research reviews the existing studies into AD prevention, progression, planning, and relevant factors for risk reduction. Additionally, the study investigates assistance systems through computerized cognitive assessment, using technology tools and applications dealing with health information recording, drug monitoring, location, and behavior tracking.
