Burch HB. Accordingly, a recent meta-analysis aiming to evaluate the risk of cognitive impairment and dementia in mild thyroid dysfunction showed an association between sHT and risk of developing dementia, whereas elderlg risk was not found in sHT [ 54 ]. Among patients with subclinical hypothyroidism, those at greater risk of progressing to clinical disease, and who may be considered for therapy, include patients with thyroid-stimulating hormone levels greater than 10 mIU per L and those who have elevated thyroid peroxidase antibody titers. With the knowledge of the extreme variability of thyroid hormone physiopathology in the elderly, it is crucial to avoid a superficial diagnosis and therefore, inappropriate treatment [ 44 ].

REVIEW article

Franklyn JA. Overall, these severee show how the aging process is characterized by a downregulation of the hypothalamus-pituitary-thyroid-peripheral-tissues axis, although it is yet to be established whether these changes reflect an adaptive mechanism to reduced metabolic functions or instead, represent a protective mechanism to preserve the body from excessive catabolism. In summary, there is little evidence in the literature to clearly link overt hypothyroidism with reduced mobility or increased frailty, and in subclinical hypothyroidism there is some published data suggestive of improvements in these domains compared to euthyroid individuals, although the data is conflicting here.

As a service to our readers, Harvard Health Publishing provides access to our library of archived content. However, it is still a matter of debate whether the reduced thyroid function in the elderly as a result of either reduced pituitary gland secretion or reduced hormone production is just a consequence of a reduced metabolic request or instead represents a real protective condition against the increased catabolism seen in the aging process [ 38 ].

Reduced blood volume, weaker contractions of the heart muscle, and a slower heart rate—all caused by low thyroid hormone levels—can contribute to heart failure, when your heart can't pump out blood as effectively as it should The ineffective pumping may cause subtle symptoms such as feeling less energetic or just walking more slowly. However, the target TSH and thyroid hormone levels are uniform across the age groups and age-specific ranges are not utilised.

Conclusions Current evidence suggests that threshold for treating mild subclinical elderl in older people should be high. The fundamental clinical principle in the case of glandular deficiency is replacement therapy, while available; in the case of overt hypothyroidism, the treatment of choice is l -T4 replacement therapy, also in the elderly [ 56 ].

The eldsrly consequences of thyroxine replacement in adult hypopituitary patients. Complex alteration of thyroid function in healthy centenarians. Beside the serum TSH cutoff value, clinicians should be advised to decide on a case-by-case basis, particularly if patients have other risk factors for cardiovascular disease and encompass gypothyroidism and symptoms possibly associated with sHT. Thyroid hormones exert an important metabolic function across adulthood and in the aging phases [ 45 ]. Apart from the higher mortality in patients with suppressed TSH the most important risks of overtreatment are those affecting the heart 50the bones 91the brain 92 and muscle function In the Health, Aging and Body Composition Study, an elderly population 70 to 79 years of age was assessed to evaluate the incident-adjudicated dementia and change in the cognitive performance; among the whole population, over 9 years of follow-up, the risk to develop dementia was found increased in sHT but not in sHT [ 53 ].

  • Treatment may therefore begin with L-T4 in a dose of 25 to 50 micrograms daily, and the dose increased in steps every weeks until the laboratory tests show a gradual return of blood thyroid hormone and thyroid-stimulating hormone TSH levels to the normal range.

Arch Intern Med. Subsequently, a number of cross-sectional studies have been performed across hypothroidism geographical locations and studying various age groups. However, there is no reliable laboratory index of peripheral thyroid hormone action, but some tests 2760including sex steroid- binding globulin, serum ferritin, serum angiotensin- converting enzyme, as well as oxygen consumption resting energy expendituresystolic time interval, and cardiac contractility 6162may be useful in rare unclear cases of following the individual response in situations of suspected thyroid hormone resistance or during long-term suppressive therapy with T4. Thyroid hormone receptors regulate many key physiologic processes. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide.

Thanks for visiting. Overt hypothyroidism determines changes in myocardial contractility, vascular resistance, and endothelial function, which are usually reversible with adequate treatment [ 4 ]. Neurol Barcelona, Spain ;— They may also have:. Interestingly, another recent meta-analysis from 13 studies demonstrates a substantial relationship between sHT and cognitive impairment only in individuals younger than 75 years of age and those with higher TSH concentrations, whereas no correlation was found while considering all of the studies as a whole [ 55 ]. The value of ultrasonography in predicting autoimmune thyroid disease.

To date, no studies evaluating a systematic approach to symptom monitoring via patient-reported outcomes have been published, severe hypothyroidism in elderly it may offer a valuable source of information and facilitate adherence. For the latter, the often-complex L-T4 regimen, with doses varying over weekdays to achieve optimal titration, may be a particular challenge. Lacking good evidence the treatment target is mostly empirically based and could be either a TSH ideally related to an age specific reference rangeb other biochemical and clinical indices of thyroid function or c patient-experienced variables, e.

In addition, thyroid hormone requirements change with age and older patients on replacement therapy are more susceptible to the effects of thyroid hormone excess such as osteoporosis and atrial fibrillation.

  • Age and gender substantially influence the relationship between thyroid status and the elderly profile: results from a large cross-sectional study. According to these considerations, a comprehensive, multidimensional geriatric assessment [ 58 ] may be helpful in the clinical approach to older patients with increased serum TSH values [ 44 ].

The severe hypothyroidism in elderly symptoms are also quite common in euthyroid individuals and thus often overlap with the symptoms developed in hypothyrkidism with hypothyroidism 9. There is growing evidence that treatment of subclinical hypothyroidism may not be beneficial, particularly in an older person. Both overt hypothyroidism as well as minor elevations of serum thyrotropin TSH levels associated with thyroid hormones within their respective reference ranges termed subclinical hypothyroidism are relatively common in older individuals. Oxford Academic. Home » Older Patients and Thyroid Disease.

Read elderly Issue. Thus, suppressed TSH has in population studies consistently been associated with a higher mortality and other adverse effects compared to people with normal or even higher TSH concentrations Table 5 87 — Drugs interfering with l -T4 absorption are also a frequent cause of hypothyroidism, despite proper replacement therapy, especially in the elderly [ 19 ]. A Comprehensive Guide for the Clinician. Search Menu.

Primary gland failure can result from congenital abnormalities, autoimmune destruction Hashimoto diseaseiodine deficiency, and infiltrative diseases. This was a large and appropriately powered study, and the authors argue that in this very elderly cohort, whilst depression, dementia and thyroid dysfunction are all relatively common, the relationship appears coincidental rather than causal. The fewer symptoms in older patients will also impede recognition of a potential treatment effect in randomized clinical trials. Timing and magnitude of increases in levothyroxine requirements during pregnancy in women with hypothyroidism. The tests include measurement of circulating TSH and thyroid hormones in the serum. The log TSH-free T4 relationship in a community-based cohort is nonlinear and is influenced by age, smoking and thyroid peroxidase antibody status.
