Scientists from the University of Michigan found that exposure to low levels of thyrotropin due to endogenous or exogenous thyrotoxicosis in older adults is associated with an increased risk of cognitive impairment. The research was published in the journal JAMA Internal Medicine.
Thyrotoxicosis is a clinical syndrome that occurs when there is an increase in the level of thyroid hormones in the blood. Excess of these hormones affects the functioning of various organs and systems. Patients complain of dry skin, brittle hair, puffy faces, and may experience slight tremors of the eyelids, fingers, and even the whole body. There are slight temperature fluctuations, increased nervous excitability, sweating, feeling of heat and restlessness.
65 thousand patients aged 65 and over were included in the research. The authors found that the incidence of cognitive impairment by age 75 in thyrotoxicosis-exposed and unexposed patients was 11% and 6.4%. Across all age groups, thyrotoxicosis from all causes was associated with a risk of various cognitive impairments
“Increased risk of cognitive impairment is one of the potential adverse consequences of excess thyroid hormone, a common consequence of thyroid hormone therapy,” the authors said.
