The aging process currently encompasses quite a generation and exceeds three decades. The common framework for describing different older adult populations is “young-old” , “old” , and “old-old.” The “young-old” are people in their 60s and early 70s who are active and healthy. The “old” are people in their 70s and 80s who have chronic illnesses and are slowing down with some bothersome symptoms. The “old-old” or “oldest-old” are often sick, disabled, and maybe even nearing death. When caring for older adults as a clinician or as a caregiver, predicting the longer term then planning for the foremost likely aging trajectories are key steps. This paper presents a model for the clinical and public health needs of adults over age 85. The changes related to a chronologic age of 85 are often divided into a couple of domains: normal aging, common diseases, and functional, cognitive/psychiatric, and social changes. Although changes are often described in every organ system, this review will address changes with public health and clinical decision-making implications. the utilization of hearing aids could reverse adverse effects on the standard of life, and cognitive function in elderly adults. Unfortunately, among individuals with deafness in one study, only 14.6% reported currently employing a hearing aid. Often, insurance doesn't offer coverage for these devices.
