Aim: This study aimed to assess the cognitive development of individuals with congenital hypothyroidism.
Methods: Using hospital records, we identified 180 patients with congenital hypothyroidism born between 1980 and 2018 in Turku and Kuopio University Hospital catchment areas. Cognitive development was evaluated in 22 adults (7 males and 15 females) and 20 children (8 males and 12 females) using age-specific Wechsler Intelligence Scales.

Context: Patients with congenital hypothyroidism (CH) are affected more often than the general population by other chronic diseases and neurological difficulties.
Objective: The aim of this nationwide population-based register study was to investigate the incidence of congenital malformations, comorbidities, and the use of prescribed drugs in patients with primary CH.
Methods: The study cohort and matched controls were identified from national population-based registers in Finland.
Introduction: Newborn screening of congenital hypothyroidism (CH) has enabled early treatment with levothyroxine (LT4), ensuring normal growth and development. The initial LT4 dose recommendation has increased over decades. We evaluated whether the increased LT4 dosing influenced thyroid-stimulating hormone (TSH) and thyroxine (fT4) concentrations, growth, or treatment-related symptoms.

Methods: Two independent study cohorts, a national and a regional, were collected from national registers and patient records.
