Is thyroid status a common denominator of age-related disease?

Doctoral Thesis

Worldwide, life expectancy has increased, which also resulted in an increasing number of people reaching old age. With aging, several age-related diseases commonly occur, such as dementia, osteoporosis and cardiovascular disease. The occurence of these diseases with age is highly heterogeneous. The research described in this thesis assessed the role of thyroid hormones in the etiology of age-related diseases. Based on the results, variation in blood levels of thyroid hormones do not appear to play a major role in the development of cogniitve decline, osteoporosis, anemia, diabetes mellitus or cardiovascular disease. Therefore, we conclude that is unlikely that thyroid hormones are a modifiable risk factor in the aging process. Nevertheless, many other research questions remain regarding thyroid hormones and older individuals.
