Congenital hypothyroidism

Congenital hypothyroidism is a partial or complete absence of function of the thyroid gland that affects infants from birth. People with congenital hypothyroidism have lower-than-normal levels of these vital hormones. Hypothyroidism is a condition that occurs when the thyroid gland does not grow or function properly. In the majority of cases, a normal-sized or enlarged thyroid gland is present, but thyroid hormone manufacturing is reduced or absent. Despite the fact that the procedure itself is unimpaired, it is still true that decreased or absence of thyroid hormone production is owing to inadequate stimulation of the manufacturing process. The lack of thyroid hormones is responsible for congenital hypothyroidism. Affected babies may have no signs of gastrointestinal hypothyroidism, but some babies with congenital hypothyroidism are less active and sleep more than normal. Hypothyroidism can also be related to disorders that affect other organs and tissues in the body.

Brain-lung-thyroid syndrome

Brain-lung-thyroid syndrome is a group of disorders that influence the brain, lungs, and thyroid gland. About 51% of those affected people have problems with all three organs, about 31% have brain and thyroid disorders, and around 10% have brain and lung disease, and about 10% have heart and lung problems. Nearly everyone with brain-lung-thyroid disease has brain-related movement abnormalities. Individuals with brain-lung-thyroid syndrome may have other abnormalities, such as difficulty coordinating movements, muscle twitches, and voluntary muscle contractions that result in twisting and repetitive movements. Many affected individuals have decreased thyroid function from birth, resulting in lower-than-normal thyroid hormone levels. Even though the thyroid hormone levels are not correct, some people have a milder condition called compensated or subordinate hypothyroidism, in which thyroid hormone levels are within the normal range. Although most people with brain-lung-thyroid disease have a normal-sized thyroid, some affected individuals have a reduced in size or absent, in certain affected individuals. Although a shortage of thyroid hormones can lead to intellectual impairment and other health problems, it is unclear if brain-lung-thyroid syndrome sufferers have hypothyroidism or brain abnormalities related to the condition. Lung problems in brain-lung-thyroid syndrome are typical. Other impacted individuals experience extensive lung damage or scarring in the lungs, both of which can lead to respiratory difficulties. People with brain-lung-thyroid disease also have persistent respiratory infections that can be life-threatening. People with brain-lung-thyroid syndrome have a higher risk of lung cancer than those in the general population.
