Piccini CD, Morillos MB, Formoso CR, Rodrigues MADC, Londero RG. Increased cerebrospinal fluid pressure and nephrotic syndrome: A case report and literature review. Clin Neurol Neurosurg 2023; 225:107567. [PMID: 36592532 DOI: 10.1016/j.clineuro.2022.107567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 12/09/2022] [Accepted: 12/18/2022] [Indexed: 12/24/2022]
Abstract
OBJECTIVE To analyze how nephrotic syndrome (NS) correlates to increased intracranial pressure (ICP), and to present a case of an adult patient whose initial manifestation of NS was cephalalgia, with the later identification of raised ICP. METHODS Data were retrospectively retrieved from the patient's record, and a literature search with the keywords "nephrotic syndrome", "intracranial hypertension" and "headache" was conducted in PubMed and Embase. RESULTS This is a rare description of co-occurrence of NS and raised ICP in a 48-year-old man, in which ICP normalizes after NS remits. There is no known cause for the raised ICP of our patient. Ten reports (n = 13) of concomitant occurrence of increased ICP and NS were described in the literature, both in children and adults. Cerebral venous thrombosis (CVT) was the most likely underlying cause for the majority of them. For one patient, the underlying cause was meningoencephalitis. Finally, in one case, the cause is unknown, but CVT was not discarded. CONCLUSION The early suspicion of elevated ICP is warranted in patients with new-onset headache and NS. It is possible that NS could both directly and indirectly lead to increased ICP through yet unknown mechanisms, although this direct causal relationship cannot be currently established.

Neuroophthalmology 2022; 47:63-74. [PMID: 36891406 PMCID: PMC9988343 DOI: 10.1080/01658107.2022.2153874] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 11/10/2022] [Accepted: 11/20/2022] [Indexed: 12/23/2022] Open
Abstract
Idiopathic intracranial hypertension (IIH) affects both children and adults. There are currently no clinical trials in IIH for those who are adolescents or children. The aims of this narrative review were to characterise the differences between pre- and post-pubertal IIH and to highlight the need to be more inclusive in clinical trial planning and recruitment. A detailed search of the scientific literature was performed using the PubMed database, from inception until 30 May 2022 using keywords. This included English language papers only. The abstracts and full texts were reviewed by two independent assessors. The literature revealed that the pre-pubertal group had a more variable presentation. The presenting features in the post-pubertal paediatric group were more akin to adults with headache as the dominant feature. They were also more likely to be female and have an increased body mass index. A clear limitation of the literature was that a number of paediatric studies had variable inclusion criteria, including secondary causes of raised intracranial pressure. Pre-pubertal children do not display the same predilection towards the female sex and obesity as post-pubertal children, who have a similar phenotype to the adult cohort. Inclusion of adolescents in clinical trials should be considered given the similar phenotype to adults. There is a lack of consistency in the definition of puberty, making the IIH literature difficult to compare. Inclusion of secondary causes of raised intracranial pressure has the potential to confound the accuracy of analysis and interpretation of the results.

[PMID: 36452803 PMCID: PMC9702258 DOI: 10.1007/s12070-021-02766-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2021] [Accepted: 07/11/2021] [Indexed: 11/28/2022] Open
Abstract
To study the various computed tomography (CT) cisternogram findings in idiopathic cerebrospinal fluid (CSF) leaks and the long term treatment modalities after surgical repair of idiopathic CSF leaks. This was a descriptive study conducted among 25 patients in MCV memorial ENT trust hospital, Pollachi between May 2014 and May 2020 amongst patients who underwent CT cisternogram for unilateral or bilateral spontaneous rhinorrhea with or without associated headache, visual disturbances and papilloedema diagnosed to be idiopathic CSF leak by investigations. These patients then underwent CSF leak repair and postoperatively were managed with weight reduction, low salt diet and diuretic therapy. Post surgery these patients were followed up for a period of 12 months and were evaluated on the basis of presence or absence of headache, rhinorrhea and papilloedema at the end of 1st month, 3rd month, 6th month and 1 year and data was collected. CT cisternogram findings were evaluated by proportion method and evaluation of long term management was done using proportion and repeated measures ANOVA for all patients. Evidence of the presence of previously mentioned CT cisternogram or contrast MRI findings at the end of 1 year of post-surgical treatment was recorded where patients were willing for the same. CT Cisternography was done for all patients and 72% patients had empty sella appearance while 28% had partially empty sella. Other findings included perioptic filling, optic blunting and arachnoid pits which were found in 11(44%), 8(32%) and 12(48%) of patients respectively. Only 3(12%) out of 25 patients had an encephalocoele. The commonest site of leak in CT cisternography was the cribriform plate (52%) followed by lateral recess of sphenoid (48%). None of the patients had multiple sites of leak in CT cisternography. On follow up post surgery maximum resolution of symptoms was found at the end of 12 months where 23 out of 25 patients improved. In our study, out of 25 only 5 patients agreed to undergo post diuretic therapy MRI scan out of which 2 patients had partially empty sella and 3 had normal sella indicating resolution of BIH. CT cisternography is an important investigation which aids in the diagnosis of CSF rhinorrhea due to idiopathic intracranial hypertension (IIH). The medical management of IIH post surgery such as weight reduction, salt restriction and diuretic therapy is also crucial to prevent recurrence of symptoms.

Abstract
AIM To describe the clinical characteristics of children with pseudotumor cerebri syndrome (PTCS) who were diagnosed according to the modified Dandy criteria and to reclassify them according to the newly proposed diagnostic criteria by Freidman. METHODOLOGY This retrospective study included the period from January 2016-to July 2021. RESULTS 50 patients were included; 34 males and 16 females with a male to female ratio of 2.1:1. The average age at onset of symptoms was 8 years. Obesity was noticed in 6 (12%) patients; 34 (68%) had symptoms upon presentation. The most common presenting symptom was headache (28 patients; 56%), papilledema was present in 33 (66%) patients. Most patients (37; 74%) had an initial cerebrospinal fluid (CSF) pressure ≥280 mmH2O. At last follow-up, papilledema resolved in 11/32 (34.3%) patients, and headache resolved in 17/23 (74%) patients. 22/50 (44%) patients fulfilled the definite criteria proposed by Freidman, 11/50 (22%) fulfilled the probable, 10/50 (20%) were categorized as possible, and 7 (14%) patients were categorized as unmet. CONCLUSION PTCS is a chronic condition. Managing patients who do not have papilledema or who do not meet the newly proposed higher CSF pressure is challenging. Although, applying the newly proposed criteria captured most of our patients, however, around one quarter were managed based on clinical experience. This study indicates a strong need for future guidelines tailored specifically for children, taking into consideration that the cut-off point of CSF pressure might not be similar for all populations.

Abstract
BACKGROUND The pathophysiology underlying pseudotumor cerebri syndrome (PTCS) is complex and not well understood. There are clear differences between PTCS in adults and pediatrics. Few and isolated case reports have suggested that adrenal function may be involved, yet no large cohort study has examined this relationship. METHODS We conducted a retrospective single-center study of children who presented with a diagnosis of PTCS and had cortisol testing measured between January 2010 and September 2019. We included all subjects meeting the revised PTCS diagnostic criteria after the chart review. Based on morning, random or 1-μg cosyntropin stimulated cortisol levels, adrenal functioning was classified as: (1) insufficient (peak cortisol <16 μg/dL and AM cortisol <5 μg/dL), (2) at risk (peak cortisol 16-20 μg/dL, AM cortisol 5-13 μg/dL, or random <13 μg/dL), or (3) sufficient (peak cortisol >20 μg/dL and AM or random cortisol >13 μg/dL). RESULTS A total of 398 individuals were reviewed, and 64 were included for analysis. Of these, 40.6% were men, of mixed race and ethnicity with a mean age of 10.5 (SD 4.7) years. Of these, 23% and 52% had insufficient or at-risk cortisol levels. The majority of those in the insufficient (70%) or at-risk (80%) groups were exposed to topical, nasal, or inhaled glucocorticoids but not systemic. Only 60% and 12% of those with PTCS with insufficient or at-risk cortisol testing, respectively, underwent definitive testing with a stimulation test. CONCLUSIONS Glucocorticoid use and hypocortisolism are prevalent in PTCS and need consideration as a potential underlying cause. Most children had insufficient or at-risk cortisol levels, and many did not undergo further testing/workup. Children who present with PTCS, particularly young, males should be evaluated for adrenal insufficiency and its risk factors, including nonsystemic steroids. Prospective studies are necessary to further evaluate the effect of cortisol in relation to pediatric PTCS.

Abstract
BACKGROUND Idiopathic intracranial hypertension is characterized by increased intracranial pressure without any pathological findings on neuroimaging, except for signs of high intracranial pressure. Before diagnosing idiopathic intracranial hypertension secondary causes of increased intracranial pressure should be excluded. OBJECTIVE to characterize the phenotype of patients with secondary intracranial hypertension and to identify possible risk factors for secondary intracranial hypertension. METHODS We have systematically searched the PubMed database. The publications were analyzed according to the patient phenotype, age, gender, comorbidities, body mass index/weight status, and additional medication. The results are summarized in four categories: medication, infection, hormonal induced intracranial hypertension and miscellaneous groups of diseases related to sIH. RESULTS We identified 105 eligible papers which included 272 cases. There were 49.6% pediatric cases. Among the adult group,70.9% were women. A total of 40.4% of all cases were obese or overweight, 27% among adults and 13.4% among pediatric cases. Increased BMI and recent weight gain, anemia, renal diseases and hypertension were the most frequent comorbidities related to sIH. CONCLUSION Among sIH patients, 40.4% were obese or overweight; two thirds were women. We recommend that even patients with a typical IIH phenotype should be screened for secondary causes.

Abstract
Nance-Horan syndrome (NHS) is a rare X-linked developmental disorder caused mainly by loss of function variants in the NHS gene. NHS is characterized by congenital cataracts, dental anomalies, and distinctive facial features, and a proportion of the affected individuals also present intellectual disability and congenital cardiopathies. Despite identification of at least 40 distinct hemizygous variants leading to NHS, genotype-phenotype correlations remain largely elusive. In this study, we describe a Sicilian family affected with congenital cataracts and dental anomalies and diagnosed with NHS by whole-exome sequencing (WES). The affected boy from this family presented a late regression of cognitive, motor, language, and adaptive skills, as well as broad behavioral anomalies. Furthermore, brain imaging showed corpus callosum anomalies and periventricular leukoencephalopathy. We expand the phenotypic and mutational NHS spectrum and review potential disease mechanisms underlying the central neurological anomalies and the potential neurodevelopmental features associated with NHS.

Abstract
Wieacker-Wolff syndrome (WWS) is an X-linked Arthrogryposis Multiplex Congenita (AMC) disorder associated with broad neurodevelopmental impairment. The genetic basis of WWS lies in hemizygous pathogenic variants in ZC4H2, encoding a C4H2 type zinc-finger nuclear factor abundantly expressed in the developing human brain. The main clinical features described in WWS families carrying ZC4H2 pathogenic variants encompass having a short stature, microcephaly, birth respiratory distress, arthrogryposis, hypotonia, distal muscle weakness, and broad neurodevelopmental delay. We hereby report a Sicilian family with a boy clinically diagnosed with WWS and genetically investigated with exome sequencing (ES), leading to the identification of a c.593G>A (p. R198Q) hemizygous pathogenic variant in the ZC4H2 gene. During the first year of life, the onset of central hypoadrenalism led to recurrent hypoglycemic events, which likely contributed to seizure susceptibility. Also, muscle biopsy studies confirmed a pathology of the muscle tissue and revealed peculiar abnormalities of the neuromuscular junction. In conclusion, we expand the phenotypic spectrum of the WWS-related neurodevelopmental disorders and discuss the role of ZC4H2 in the context of the potential neuroendocrinological and neuromuscular features associated with this condition.

Abstract
OBJECTIVES Brain morphology and its relation to endocrine parameters were examined, in order to determine the link of these parameters to treatment outcome to psychopharmacological treatment in depressed patients. METHODS We examined the potentially predictive value of Magnetic Resonance Imaging (MRI) parameters related to mineralocorticoid receptor (MR) function on the treatment outcome of depression. 16 inpatients with a major depressive episode (MDE) were studied at baseline and 14 of them approximately six weeks later. Physiological biomarkers and 3-T-structural MRI based volume measures, using FreeSurfer 6.0 software, were determined. RESULTS Non-responders (<50% reduction of HAMD-21; n = 6) had a significantly smaller volume of the right anterior cingulate cortex, a significantly larger ventricle to brain ratio (VBR) and third ventricle volume, and smaller volumes of the central and central-anterior corpus callosum (CC) in comparison to responders (n = 7; all p ≤ 0.05). Correlational analysis (Spearman) demonstrated that larger ventricle volume was correlated to a worse treatment outcome, higher body mass index (BMI) and smaller CC segment volume, whereas the total CC volume was negatively correlated to the saliva aldosterone/cortisol concentration ratio (AC-ratio). CONCLUSION Large ventricular volume may be a predictive marker for worse treatment response to standard antidepressant treatment, potentially via compression of white matter structures. A mediating role of the previously identified markers BMI and the AC-ratio, is suggested.

Abstract
Objective:
The purpose was to study the epidemiological and clinical features of Pediatric Pseudotumor Cerebri; we especially evaluated age, sex, sexual maturity, weight, symptoms, duration of the episode, visual acuity, correlation with systemic diseases or drugs.
Methods:
We investigated a population of 40 children (80 eyes), aged between 2 and 18 years, that referred to our Centre (Città della Salute e della Scienza di Torino - presidio Ospedale Regina Margherita) from 2000 to 2018.
All the patients were monitored with visual field exam, fundus exam and Frisen classification, pupillary reflexes, best corrected visual acuity, orthoptic exam.
Then, the demographic characteristics, BMI (body max index) and weight changes, the correlation with systemic diseases or drugs, the Relative Afferent Pupillary Defect (RAPD), the VI cranial nerve deficit, the time required for the diagnosis, the modality of onset, the correlation between diagnosis delay and best corrected visual acuity, the resolution time and the probability of recurrence were studied.
Results:
We observed 2 age peaks in our population, one consisting of adolescents (aged between 11 and 14 years) and one consisting of younger children aged between 4 and 7 years, with a statistically significant correlation between age and BMI.
The deficit of the VI cranial nerve and the diplopia were resolved within the first month, despite the longer time of resolution of the papilledema.
Headache was the main onset symptom, but after reclassifying onset symptoms per weight classes, in overweight children, we found an increased variability of symptoms (dizziness, postural instability, photophobia, nausea, vomit, strabism and diplopia, visual fogging, drowsiness, irritability). Moreover, we found only one totally asymptomatic case, during a routine visit, in a 6 years old overweight child with Down syndrome.
Conclusion:
The Pediatric Pseudotumor Cerebri is, even nowadays, a little known pathology.
To provide a correct diagnostic assessment, it will be imperative to recollect the epidemiological features of this disease.

Abstract
Pseudotumor cerebri syndrome (PTCS) is defined by the presence of elevated intracranial pressure in the setting of normal brain parenchyma and cerebrospinal fluid. PTCS can occur in the pediatric and adult populations and, if untreated, may lead to permanent visual loss. In this review, discussion will focus on PTCS in the pediatric population and will outline its distinct epidemiology and key elements of diagnosis, evaluation and management. Finally, although the precise mechanisms are unclear, the underlying pathophysiology will be considered.

ANNALES D'ENDOCRINOLOGIE 2017; 78:9-13. [PMID: 28168953 DOI: 10.1016/j.ando.2016.07.993] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/22/2016] [Revised: 07/06/2016] [Accepted: 07/13/2016] [Indexed: 11/24/2022]
Abstract
OBJECTIVES There is a growing evidence of increased risk of cerebrovascular events in primary aldosteronism (PA). Nevertheless, acute neurologic ailment as presenting feature of PA is uncommon. Our aim is to highlight the diagnosis challenges in stroke unmasking PA and to discuss the underlying physiopathology and management dilemmas. MATERIALS AND METHODS We hereby describe three consecutive rare cases of stroke revealing PA. All patients had brain imaging and thorough biological and morphological assessment to rule out other etiologies of stroke. The diagnosis of primary aldosteronism was established according to the Endocrine Society Clinical Practice Guideline, with a review of the literature on the spectrum of neurologic manifestations in PA. RESULTS We report on three cases, two women and a man, presenting with ischemic or hemorrhagic stroke, of early onset in two of them. All of the reported patients had hypertension and hypokaliemia. This association prompted the assessment of renin angiotensin aldosterone system (RAAS) disclosing PA, which was due to bilateral adenomas in the first one or bilateral adrenal hyperplasia in the two others. All patients refused the surgical option and received spironolactone with recurrence of stroke in one of them due to treatment incompliance. CONCLUSION Although cerebrovascular events are quite common in PA, their occurrence as initial feature can be misleading. The association of hypokaliemia and refractory hypertension in ischemic or hemorrhagic strokes should prompt an assessment of the RAAS to rule out PA and initiate adequate management as soon as possible in order to avoid further complications.

Abstract
Severe visual loss may occur in patients with pseudotumor cerebri (PTC), also known as idiopathic intracranial hypertension. Transverse sinus stenosis is 1 cause of PTC syndrome. Although the role of transverse sinus stenosis in the pathogenesis of the disease remains controversial, recent case series of transverse sinus stenting have reported very high rates of symptom response and resolution of papilledema with improvement or at least stabilization of the visual fields and visual acuity (Ahmed et al., 2011).1 We report a previously unpublished complication of diffuse, nonaneurysmal subarachnoid hemorrhage following angioplasty and stenting in a patient with refractory PTC.

Pediatric Idiopathic Intracranial Hypertension: Age, Gender, and Anthropometric Features at Diagnosis in a Large, Retrospective, Multisite Cohort. Ophthalmology 2016; 123:2424-2431. [PMID: 27692528 DOI: 10.1016/j.ophtha.2016.08.004] [Citation(s) in RCA: 44] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2016] [Revised: 07/27/2016] [Accepted: 08/02/2016] [Indexed: 10/20/2022] Open
Abstract
PURPOSE To examine anthropometric and maturational characteristics at diagnosis in pediatric idiopathic intracranial hypertension (IIH). DESIGN Retrospective, international, multisite study. PARTICIPANTS Pediatric patients (2-18 years of age at diagnosis) with IIH. MAIN OUTCOME MEASURES Body mass index (BMI), height, and weight Z-scores; sexual maturation. METHODS Cases of IIH were identified retrospectively based on diagnostic code, pediatric neuro-ophthalmologist databases, or both and updated diagnostic criteria (2013) were applied to confirm definite IIH. Anthropometric measurements were converted into age- and gender-specific height, weight, and BMI Z-scores CDC 2000 growth charts. When available, sexual maturation was noted. RESULTS Two hundred thirty-three cases of definite IIH were identified across 8 sites. In boys, a moderate association between age and BMI Z-scores was noted (Pearson's correlation coefficient, 0.50; 95% confidence interval [CI], 0.30-0.66; P < 0.001; n = 72), and in girls, a weak association was noted (Pearson's correlation coefficient, 0.34; 95% CI, 0.20-0.47; P < 0.001; n = 161). The average patient was more likely to be overweight at diagnosis at age 6.7 years in girls and 8.7 years in boys, and obese at diagnosis at age 12.5 years in girls and 12.4 years in boys. Compared with age- and gender-matched reference values, early adolescent patients were taller for age (P = 0.002 in girls and P = 0.02 in boys). Data on Tanner staging, menarchal status, or both were available in 25% of cases (n = 57/233). Prepubertal participants (n = 12) had lower average BMI Z-scores (0.95±1.98) compared with pubertal participants (n = 45; 1.92±0.60), but this result did not reach statistical significance (P = 0.09). CONCLUSIONS With updated diagnostic criteria and pediatric-specific assessments, the present study identifies 3 subgroups of pediatric IIH: a young group that is not overweight, an early adolescent group that is either overweight or obese, and a late adolescent group that is mostly obese. Data also suggest that the early adolescent group with IIH may be taller than age- and gender-matched reference values. Understanding these features of pediatric IIH may help to illuminate the complex pathogenesis of this condition.

Abstract
Pseudotumor cerebri syndrome (PTCS) is defined by the presence of elevated intracranial pressure (ICP) in the setting of normal brain parenchyma and cerebrospinal fluid (CSF). Headache, vision changes, and papilledema are common presenting features. Up to 10% of appropriately treated patients may experience permanent visual loss. The mechanism(s) underlying PTCS is unknown. PTCS occurs in association with a variety of conditions, including kidney disease, obesity, and adrenal insufficiency, suggesting endocrine and/or metabolic derangements may occur. Recent studies suggest that fluid and electrolyte balance in renal epithelia is regulated by a complex interaction of metabolic and hormonal factors; these cells share many of the same features as the choroid plexus cells in the central nervous system (CNS) responsible for regulation of CSF dynamics. Thus, we posit that similar factors may influence CSF dynamics in both types of fluid-sensitive tissues. Specifically, we hypothesize that, in patients with PTCS, mitochondrial metabolites (glutamate, succinate) and steroid hormones (cortisol, aldosterone) regulate CSF production and/or absorption. In this integrated mechanism review, we consider the clinical and molecular evidence for each metabolite and hormone in turn. We illustrate how related intracellular signaling cascades may converge in the choroid plexus, drawing on evidence from functionally similar tissues.

Abstract
Idiopathic intracranial hypertension (IIH), also known as primary pseudotumor cerebri syndrome (PTCS), is a condition of unknown etiology which affects primarily overweight, reproductive-aged women and causes increased intracranial pressure (ICP). This review discusses the recently revised diagnostic criteria for PTCS for adults and children. Additionally, the role of obesity in the epidemiology, etiology, and management of IIH as well as the current knowledge of obesity profiles and markers in IIH are reviewed. We also highlight the emerging, unifying theory of the neuroendocrine effects on the mineralocorticoid receptor to explain a possible mechanism for the increased cerebrospinal fluid production and ICP in secondary PTCS.

Adrenal disorders and the paediatric brain: pathophysiological considerations and clinical implications. Int J Endocrinol 2014; 2014:282489.

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.
