Congenital Hypothyroidism Screening and Management
Summary
Congenital hypothyroidism (CH) is a common yet often clinically silent endocrine disorder in newborns, affecting approximately 1 in 2,000 to 1 in 4,000 live births worldwide. Early detection through population-based newborn screening (NBS) is critical to prevent irreversible neurocognitive impairment. Screening strategies predominantly measure thyroid stimulating hormone (TSH) or thyroxine (T4) levels in heel-prick blood spots within the first days of life, although the choice of marker and threshold varies by region. Once CH is diagnosed, prompt initiation of levothyroxine therapy at appropriate doses ensures rapid restoration of euthyroidism, optimises cognitive outcomes and guides follow-up to distinguish permanent from transient forms. Management protocols include frequent biochemical monitoring in infancy, structured trials off treatment at around three years of age and tailored approaches for special populations, such as preterm or low-birth-weight infants and those with central CH. Recent efforts focus on refining screening thresholds, addressing logistical and educational barriers to universal coverage and understanding the evolving incidence of transient hypothyroidism.

Congenital Hypothyroidism Screening and Management publication trend
The graph below shows the total number of articles in congenital hypothyroidism screening and management across all publications each year (not limited to Nature Index journals).
Technical terms
Congenital hypothyroidism (CH): Thyroid hormone deficiency present at birth due to thyroid dysgenesis, dyshormonogenesis or central causes.
Newborn screening (NBS): Population-based testing of neonates shortly after birth to identify conditions where early intervention improves outcome.
Thyroid stimulating hormone (TSH): Pituitary hormone that regulates thyroid hormone synthesis; elevated levels indicate primary thyroid dysfunction.
Transient congenital hypothyroidism (tCH): Temporary thyroid insufficiency in neonates that resolves, often by age three, without lifelong treatment.
Levothyroxine: Synthetic form of thyroxine (T4) used as first-line therapy to restore normal thyroid hormone levels.
