Pituitary, 2008
Central hypothyroidism (CH) is a rare cause of hypothyroidism due to an insufficient stimulation of an otherwise normal thyroid gland and it is caused by either pituitary (secondary hypothyroidism) or hypothalamic (tertiary hypothyroidism) defects.

Central hypothyroidism — a neglected thyroid disorder
Nature Reviews Endocrinology, 2017Central hypothyroidism is a rare and heterogeneous disorder that is characterized by a defect in thyroid hormone secretion in an otherwise normal thyroid gland due to insufficient stimulation by TSH. The disease results from the abnormal function of the pituitary gland, the hypothalamus, or both.

A 15-mth-old male child of consanguineous parents, presented with classical features of congenital hypothyroidism. Serum total thyroxine (T4), total triiodothyronine (T3) and TSH were low. There was no evidence of deficiency of other pituitary hormones. Magnetic resonance imaging of the pituitary was normal.

Endocrinology and Metabolism Clinics of North America, 1992
Central hypothyroidism is an uncommon condition characterized by insufficient thyroid gland stimulation by TSH, owing to hypothalamic and/or pituitary dysfunction. It is rarely isolated but more often occurs in conjunction with deficiencies of other pituitary hormones, as well as with neurologic symptoms and signs owing to hypothalamic/pituitary ...

Central Hypothyrodism (CeH) is the hypothyroid condition due to an insufficient stimulation by thyrotropin (TSH) of an otherwise normal thyroid gland. CeH is about 1,000-fold more rare than primary hypothyroidism and raises several challenges for the clinicians, mainly because they cannot rely on the systematic use of the “reflex TSH strategy” for ...

Central hypothyroidism is an exceedingly rare form of hypothyroidism that results from a variety of conditions affecting the hypothalamus and the pituitary gland. The classic biochemical abnormality seen in these patients includes a low serum level of circulating thyroxine (T4) concomitant with an inappropriately low level of thyrotropin.

Central Hypothyroidism in Children
2014Central congenital hypothyroidism (CCH) is an underdiagnosed disorder poorly described in childhood and adolescence. Congenital defects in thyroid-stimulating hormone (TSH) synthesis, secretion or bioactivity may lead to a state of 'regulatory' hypothyroidism expressed through aberrantly low or normal TSH levels and low thyroxine (T4), a hormonal ...

Central Hypothyroidism and Hyperthyroidism
Medical Clinics of North America, 1985Thyroid function is maintained by tonic secretion of TSH by the pituitary. TSH secretion, in turn, is dependent on hypothalamic TRH production. Therefore, diseases of the hypothalamus and pituitary are frequently associated with TSH deficiency, producing central hypothyroidism.

Central Sleep Apnea in Hypothyroidism
American Review of Respiratory Disease, 1983Abstract This is a report of a 45-yr-old male patient who developed central sleep apnea syndrome because of hypothyroidism. In response to L-thyroxine therapy, the patient became euthyroid, and the apneic phenomenon disappeared.

Functional central hypothyroidism in the elderly
Aging Clinical and Experimental Research, 2008Previous studies have shown that blood concentrations of free thyroxin and basal thyroid-stimulating hormone (TSH) decrease during adult life. Suggested mechanisms include reduced thyroid activity resulting from decreased serum TSH concentrations, impairment of peripheral 5'-deiodinase, and an increase in reverse 3,5,3'-triiodothyronine due to non ...
