In some cases the sense of smell may return and for others the loss will be permanent.
Research supports the existence of changes in smell due to age. The causes of this loss are varied. There has not been considerable research into searching for a treatment as with other sensory declines. Loss of out sense of smell is not considered to be of greater consequence in our society. With the rare exception of those whose careers depend on it, there is little societal impact caused by a loss of sense of smell. For the person, they may not enjoy all of the things that they used to, but it does not carry any significant impairment with it.
There has been no formal effort dedicated towards research to restore the sense of smell, exclusive of any underlying conditions. The loss of a sense of smell is considered to go along with certain diseases or physical abilities. The underlying condition for the loss is treated and the sense of smell may come back. However, a loss of sense of smell is not treated as a condition in itself, but is treated alongside another condition. A loss of sense of smell may mean placing the person in danger and may place them at greater risks for certain hazards, but in general, this is not considered to be something that cannot be overcome with assistive devices.

Cognitive Changes Developmental cognitive occur starting age 50 moving end life. Developmental and cognitive changes The essay aims at exploring the developmental and cognitive changes that occur starting at the age of fifty years moving through end of life. The developmental changes are easily noticeable or observable, hence not much of literature or scholarly articles have been written about it. On the other hand a lot of materials, studies and researches have
In year 1799 anesthetic properties of Nitric Oxide were discovered by Humphery Davy (1778-1829) he advised that the by using nitric oxide, pain and shock of the surgical procedure can be negated. Third person who continue with Morton and Wells philosophy was Charles T. Jackson. The Fourth man who contributed to anesthetics was Thomas Mortan (Blatner, 2009). In the year 1848 James Simpson used chloroform in obstetric surgery, he
Moreover, older persons perform less accurately on the witness stand, the authors continue. One particular study of 51 senior citizens and 62 college students reflected the fact that the older people "forgot more details and were more easily swayed by suggestions from the people administering the test, as compared with college students" (Gaydon, 679). These seniors were not suffering from Alzheimer's or any other malady; they just didn't have a
Alopecia areata is a systemic hair loss disorder, which affects roughly around 4.7 million people in the United States alone. [NAAF]. It is characterized as an autoimmune disease that leads to either localized or complete hair loss. The disease is independent of race, gender or age specifications, and hence affected people represent a diverse group. The effects of the disease may either be permanent or reversible depending on the nature
Taste and Smell Age Related Changes in Perception of Flavor and Aroma It has been posited that the perception of flavor and aroma are derived from the senses of chemical irritation, taste and smell (Rawson, 2003). Together, these senses constitute what has been termed chemosensation, although these sensory systems are purportedly considerably variant in their physiology and anatomy. Nevertheless, they do have the ability to regenerate, and their noted susceptibility to aging and
While it is true that in many countries like Canada there has been a reduction in vulnerabilities such as poverty among the elderly, it is equally true that; some 3.3 million seniors still live below the poverty line Good housing and proper medical care are often out of reach for the poor elderly -- or so expensive that little money is left over for other needs. Hundreds of thousands of
