TLDR
Children with high levels of both hormones were found to be significantly more distractable on an index of cognitive attention but were reportedly less hyperactive.
Abstract
The relationship between attention and thyroid hormone was examined using a retrospective database of 85 7-year-old children with congenital hypothyroidism who received psychological evaluations and thyroid function tests on the same day. Four unique subgroups with different levels of thyroxine and thyrotropin were compared on psychological tasks and measures of attention. Children with high levels of both hormones were found to be significantly more distractable on an index of cognitive attention but were reportedly less hyperactive. Level of thyroxine accounted for over 10% of the variance in attention.

European Society for Paediatric Endocrinology consensus guidelines on screening, diagnosis, and management of congenital hypothyroidism.

TL;DR: In this paper, a systematic literature search was conducted to identify key articles relating to the screening, diagnosis, and management of congenital hypothyroidism (CH) and the evidence-based guidelines were developed with the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system, describing both the strength of recommendations and the quality of evidence.

Neurocognitive Aspects of Hypothyroidism

TL;DR: The commonly held view that hypothyroid dementia is an imminently reversible condition is only partially supported by the medical literature, which is fraught with methodological and conceptual shortcomings.

Thyroid disease in pregnancy.

TL;DR: Thyroid testing during pregnancy should be performed on symptomatic women or those with a personal history of thyroid disease to establish the diagnosis of overt hypothyroidism and the goal of treatment with levothyroxine is to return TSH to the normal range.

Congenital hypothyroidism: influence of disease severity and L-thyroxine treatment on intellectual, motor, and school-associated outcomes in young adults.

TL;DR: Long-term outcome revealed enduring cognitive and motor deficits in young adults with CH relative to control subjects andVerbal functions and Arithmetic were associated with L-thyroxine treatment variables, suggesting that more optimal treatment might be possible.

Long-term sequelae of hearing impairment in congenital hypothyroidism

TL;DR: Hearing loss and its functional consequences were evaluated retrospectively in children with congenital hypothyroidism and revealed that early speech was delayed in hearing impaired children, whereas deficits persisted in later receptive language and auditory discrimination skills.

Analysis of the elements of attention: A neuropsychological approach

TL;DR: This work presents a heuristic for clinical research in which the measurement of attention is essential, and substitutes for the diffuse and global concept of “attention” a group of four processes and links them to a putative system of cerebral structures.

The characteristics of situationally and pervasively hyperactive children: implications for syndrome definition

TL;DR: P pervasive hyperactivity, a clinically distinctive behaviour pattern, was strongly associated with general behavioural disturbance, persistence of overall disorder and marked cognitive impairment, indicating the importance of identifying the type of hyperactivity.

Dimensions and Types of Attention Deficit Disorder

TL;DR: An empirically derived cluster analysis of three factors derived from factor analyses of teacher ratings of ADD symptoms produced three distinct clusters: patients without ADD, those with both inatt attention and hyperactivity, and a group that exhibited inattention and sluggish tempo but not hyperactivity.

TL;DR: In the study sample, attention deficit-hyperactivity disorder is strongly associated with generalized resistance to thyroid hormone.

Intellectual outcome in children with fetal hypothyroidism.

TL;DR: Although most children with athyrosis were found in the delayed group, the groups did not differ in birth weight, hormone levels, or family background, and there were no differences in behavior or temperamental characteristics.
