This text explores how the use of technology, and in particular artificial intelligence, enables further research into a disease that has a very broad epidemiological profile namely Alzheimer's disease. The current focus is on technological advances and their impact on today's society, particularly in the medical field. Through careful research and numerous studies, it is anticipated that the combination of technological innovation and medicine could be a turning point for research, prevention, and diagnosis of many medical conditions, including dementia. In pursuit of this goal, robot models are being developed that can help the elderly with dementia. Artificial intelligence thus tends not only to improve and refine knowledge of the disease itself, but also to enable health systems to use it to provide better services to patients. The result will be healthcare based on a 4.0 model
