Abstract

New drug therapies for Alzheimer's disease (AD) are currently in late clinical development. Once approved, new healthcare infrastructure and services, including primary health care, will be required to meet the great demand for early and large-scale detection of AD. The need for assessment in this area was of great concern to adults. Early detection of cognitive impairment is further advanced by new technologies in the future. Identifying evidence is one of the most important steps in diagnosis to ensure that the correct diagnosis and procedure is needed. This review noted several different methods of cognitive impairment and early detection in the elderly, and the importance of having a positive attitude towards the family during discovery.
