Hormonal imbalances during development may have long-lasting effects. Using functional magnetic resonance imaging (fMRI), we compared 14 youths with Congenital Adrenal Hyperplasia (CAH), a genetic disorder of hormonal dysfunction, with 22 healthy controls on memory encoding of emotional faces. Patients remembered fewer faces than controls, particularly fearful faces. FMRI data to successfully encoded fearful faces revealed that males with CAH showed significant activations in amygdala, hippocampus, and anterior cingulate relative to unaffected males, while females with CAH demonstrated deactivations relative to unaffected females in these regions. Findings indicate that steroid abnormalities during development can have important effects on neural correlates of emotional memory.

    • "Neurological outcomes have not been systematically reported in these children, but a mild reduction in cognitive capacities and memory has been described in some, likely due to the effects of supraphysiological doses of corticosteroid replacement on the amygdala and hippocampus development [59, 60].

    ABSTRACT: Various neurological and psychiatric manifestations have been recorded in children with adrenal disorders. Based on literature review and on personal case-studies and case-series we focused on the pathophysiological and clinical implications of glucocorticoid-related, mineralcorticoid-related, and catecholamine-related paediatric nervous system involvement. Childhood Cushing syndrome can be associated with long-lasting cognitive deficits and abnormal behaviour, even after resolution of the hypercortisolism. Exposure to excessive replacement of exogenous glucocorticoids in the paediatric age group (e.g., during treatments for adrenal insufficiency) has been reported with neurological and magnetic resonance imaging (MRI) abnormalities (e.g., delayed myelination and brain atrophy) due to potential corticosteroid-related myelin damage in the developing brain and the possible impairment of limbic system ontogenesis. Idiopathic intracranial hypertension (IIH), a disorder of unclear pathophysiology characterised by increased cerebrospinal fluid (CSF) pressure, has been described in children with hypercortisolism, adrenal insufficiency, and hyperaldosteronism, reflecting the potential underlying involvement of the adrenal-brain axis in the regulation of CSF pressure homeostasis. Arterial hypertension caused by paediatric adenomas or tumours of the adrenal cortex or medulla has been associated with various hypertension-related neurological manifestations. The development and maturation of the central nervous system (CNS) through childhood is tightly regulated by intrinsic, paracrine, endocrine, and external modulators, and perturbations in any of these factors, including those related to adrenal hormone imbalance, could result in consequences that affect the structure and function of the paediatric brain. Animal experiments and clinical studies demonstrated that the developing (i.e., paediatric) CNS seems to be particularly vulnerable to alterations induced by adrenal disorders and/or supraphysiological doses of corticosteroids. Physicians should be aware of potential neurological manifestations in children with adrenal dysfunction to achieve better prevention and timely diagnosis and treatment of these disorders. Further studies are needed to explore the potential neurological, cognitive, and psychiatric long-term consequences of high doses of prolonged corticosteroid administration in childhood.

    ABSTRACT: Little is known about how steroid hormones contribute to the beneficial effect of incentives on cognitive control during adolescent development. In this study, 27 adolescents with Congenital Adrenal Hyperplasia (CAH, mean age 15.6 years, 12 female), a disorder of cortisol deficiency and androgen excess, and 36 healthy participants (mean age 16.3 years, 18 female) completed a reward-based antisaccade task. In this mixed-saccade task, participants performed eye movements towards (prosaccades) or away (antisaccades) from a peripherally occuring stimulus. On incentive trials, monetary reward was provided for correct performance, while no such reward was provided on no-incentive trials. Consistent with the hypothesis, the results showed that healthy, but not CAH adolescents, significantly improved their inhibitory control (antisaccade accuracy) during incentive trials relative to no-incentive trials. These findings were not driven by severity of CAH (salt wasters vs. simple virilizers), individual hormone levels, sex, age-at-diagnosis, or medication type (dexamethasone vs. hydrocortisone). In addition, no significant differences between groups were found on orienting responses (prosaccades). Additional analyses revealed an impact of glucocorticoid (GC) dosage, such that higher GC dose predicted better antisaccade performance. However, this effect did not impact incentive processing. The data are discussed within the context of steroid hormone mediated effects on cognitive control and reward processing.

    ABSTRACT: This chapter provides a review of neural and behavioral sex differences, with a focus on cognitive abilities, and taking a developmental perspective. There are moderate to large sex differences in some aspects of cognition, notably spatial ability. Differences arise in a number of ways, including social factors such as experience and stereotype threat, genes on the X chromosome, and sex hormones present during prenatal life and perhaps later in life. There are sex differences in several aspects of brain structure and function; the origins of these differences and their direct links to cognition are just beginning to be understood. Future work should focus on the genetic and hormonal origins of brain sex differences, links between brain and behavioral (including cognitive) sex differences, and the ways in which brain sex differences are changed by sex-differential experiences.
