Global cognition and executive functions of older adults with type 1 diabetes mellitus without dementia. J Diabetes Investig 2024; 15:922-930. [PMID: 38525910 PMCID: PMC11215676 DOI: 10.1111/jdi.14191] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 02/23/2024] [Accepted: 03/07/2024] [Indexed: 03/26/2024] Open
Abstract
AIMS/INTRODUCTION This study aimed to characterize the global cognition and executive functions of older adults with type 1 diabetes mellitus in comparison with type 2 diabetes mellitus. MATERIALS AND METHODS This study included 37 patients with type 1 diabetes mellitus aged ≥65 years and 37 age- and sex-matched patients with type 2 diabetes mellitus. Patients with dementia scoring <24 on the Mini-Mental State Examination were excluded. General cognition, memory, classic, and practical executive function were investigated. RESULTS Patients with type 1 diabetes mellitus demonstrated lower psychomotor speed scores on Trail Making Tests A and B (P < 0.001, P < 0.013) than those with type 2 diabetes mellitus. The dysexecutive syndrome behavioral assessment revealed similar results in patients with types 1 and 2 diabetes mellitus. The Wechsler Memory Scale-Revised verbal episodic memory and Montreal Cognitive Assessment Japanese version were similar in terms of general cognition, but worse delayed recall subset on the latter was associated with type 2 diabetes mellitus (P = 0.038). A worse Trail Making Test-A performance was associated with type 1 diabetes mellitus and age (P < 0.004, P < 0.029). CONCLUSIONS Executive function of psychomotor speed was worse in older outpatient adults without dementia with type 1 diabetes mellitus than in those with type 2 diabetes mellitus but with no significant differences in the comprehensive and practical behavioral assessment of dysexecutive syndrome. Patients with type 1 diabetes had more severely impaired executive function, whereas those with type 2 had greater impaired memory than executive function.

Altered gray matter volume in children with newly diagnosed type 1 diabetes mellitus. Pediatr Res 2022; 93:1342-1347. [PMID: 35918400 DOI: 10.1038/s41390-022-02227-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 06/29/2022] [Accepted: 07/08/2022] [Indexed: 11/08/2022]
Abstract
BACKGROUND Type 1 diabetes mellitus (T1DM) affects the development of cognitive function in children, which may be due to deficits in brain structures or functions. It is unclear whether children with T1DM experience alterations in the gray matter (GM) structure at the initial stages of the disease. This study investigated GM structure alterations in children with newly diagnosed T1DM. METHODS Based on 3D T1-weighted MR images, we investigated the gray matter volume (GMV) of 35 newly diagnosed T1DM children and 35 age- and sex-matched healthy controls using voxel-based morphometry. The brain regions with significant differences in GMV between the newly diagnosed T1DM children and the controls were extracted and the correlation with clinical data was assessed. RESULTS Compared with the control group, children with newly diagnosed T1DM had a lower GMV in the right inferior and middle temporal gyri, right lingual gyrus, and left superior frontal gyrus. In T1DM subjects, the GMV of the right middle temporal gyrus was positively correlated with IQ but was negatively correlated with HbA1c. CONCLUSIONS Our findings provide compelling evidence that GM abnormalities occur during early disease stages in T1DM children, which may be a potential neurobiological mechanism underlying cognitive deficits. IMPACT Using an efficient method to analyze gray matter changes in T1DM is very important. The anterior, posterior, and temporal brain regions are susceptible to T1DM in children. Recent glucose variability may affect regional gray matter volume in children with newly diagnosed T1DM. Structural changes were documented in the gray matter of the brain even at the early stages of the disease in children with T1DM.

Abstract
BACKGROUND Several factors could affect the cognitive dysfunction in patients with type 1 diabetes (T1D). OBJECTIVES To report the characteristic of cognitive dysfunction in T1D and find its association with the retinal thickness. SUBJECTS We recruited one hundred and seven patients with T1D in our study. METHODS Detailed clinical and demographic factors and Cambridge Automated Neuropsychological Test Battery (CANTAB) were performed in all participants. The age at onset>5 years old and ≤5 years old groups was defined as old- and young-onset groups. The levels of the average values of 5-year glycated hemoglobin (HbA1c_5) before study were collected. Ophthalmic study and central retinal thickness (CRT) were performed. RESULTS The median age of T1D was 24.9 years old and 57 participants were women. The median age at onset was 7.4 years old, and mean disease duration was 17.2 years. After adjusting off multiple covariates by the regression analyses, the young-onset group had significantly a longer latency in sustained attention than old-onset group (P = 0.02). The HbA1c_5 showed a significantly negative association with the sustained attention (P = 0.03). The average values of CRT showed significantly negative correlations with the reaction time in sustained attention and visual searching (P = 0.04 and P < 0.01, respectively). CONCLUSIONS Our results suggest that age at onset and glycemic control had significant impacts on different cognitive domains in T1D. The CRT had a significant correlation with sustained attention, which could be a surrogate markers of brain structural changes in T1D.

Abstract
AIMS/HYPOTHESIS We aimed to examine the association of type 1 diabetes with school wellbeing among Danish children. METHODS This is a population-based cohort study involving 436,439 Danish children, of which 1499 had a confirmed diagnosis of type 1 diabetes. The children were enrolled in grade levels 4 to 9 (middle school) in Danish public schools in the years 2014-2017. Questionnaire outcomes from the yearly National Wellbeing Survey related to self-efficacy, perceived competences, peer and teacher support, bullying and somatic symptoms were analysed. Ordered logistic regression was used to compare outcomes of children with and without type 1 diabetes, and to compare subgroups of children with type 1 diabetes by different levels of HbA1c and diabetes duration. Primary outcomes were answers to seven pre-specified questionnaire items (scale, 1 to 5). RESULTS A total of 817,679 questionnaires were initiated, of which n = 2681 were from children with type 1 diabetes. Compared with the background population, children with type 1 diabetes expressed more peer support; adjusted OR 1.17 (95% CI 1.08, 1.27). Children with diabetes also reported more often having a headache; adjusted OR 1.09 (95% CI 1.00, 1.19). Overall, children with poor glycaemic control (HbA1c >70 mmol/mol) had worse outcomes on the wellbeing measures compared with the background population. Even after adjusting for socioeconomic status, they still reported significantly worse perceived competences, less teacher support and more somatic symptoms (stomach ache and headache). CONCLUSIONS/INTERPRETATION In Denmark, children with type 1 diabetes generally feel well supported in school but have more headaches than other children. Poor glycaemic control is associated with worse psychological school-related wellbeing. Graphical abstract.

Abstract
BACKGROUND Challenges with type 1 diabetes (T1D) blood glucose management and illness-related school absences potentially influence children's educational outcomes. However, evidence about the impact of T1D on children's education is mixed. The objectives were to estimate the effects of T1D on children's educational outcomes, and compare time since T1D diagnosis (recent diagnosis [≤2 years] and 3 to 10 years long exposure) on educational outcomes. METHODS This whole-of-population study used de-identified, administrative linked-data from the South Australian Early Childhood Data Project. T1D was identified from hospital ICD-10-AM diagnosis codes (E10, ranging E101 to E109), from 2001 to 2014. Educational outcomes were measured in grade 5 by the National Assessment Program-Literacy and Numeracy (NAPLAN, 2008-2015) for children born from 1999 to 2005. Analyses were conducted using augmented inverse probability of treatment weighting. Multiple imputations was used to impute missing data. RESULTS Among 61 445 children born in South Australia who had undertaken NAPLAN assessments, 162 had T1D. There were negligible differences in the educational outcomes of children with and without T1D, and between recently diagnosed and those with longer exposure. For example, the mean reading score was 482.8 ± 78.9 for children with T1D and 475.5 ± 74.3 for other children. The average treatment effect of 6.8 (95% CI - 6.3-19.9) reflected one-tenth of a SD difference in the mean reading score of children with and without T1D. CONCLUSION Children with T1D performed similarly on literacy and numeracy in grade 5 (age ~ 10-years) compared to children without T1D. This could be due to effective T1D management.

Abstract
BACKGROUND/PURPOSE This study aimed to clarify whether brain-derived neurotrophic factor (BDNF) is a biomarker for cognitive dysfunction in children with type 1 diabetes. METHODS We conducted a cross-sectional case-control study of children aged between 6 and 18 years with type 1 diabetes and healthy volunteers. Serum BDNF level was measured in all of the studied children, and they all underwent intelligence tests with the Wechsler Intelligence Scale for Children, Fourth Edition (WISC-IV). We further compared the cognitive function and BDNF levels in the diabetic children with positive glutamic acid decarboxylase 65 antibody (GAD65-Ab) and those with negative GAD65-Ab. RESULTS Forty-five children with type 1 diabetes (mean age 14.0 ± 2.6 years, 42% male) and 50 normal controls (mean age 13.2 ± 2.3 years, 54% male) were recruited. The serum BDNF level was significantly lower in the diabetes group than in the controls (15.92 ± 7.2 vs. 18.5 ± 5.1 ng/mL, respectively, t = -2.03, p = 0.045) and much lower in the subgroup with GAD65-Ab positive type 1 diabetes. The average Full-Scale IQ, verbal comprehension, perceptual reasoning and working memory scores in the diabetes group were significantly lower than in the controls (all p < 0.05). Among the children with type 1 diabetes, poor glycemic control was related to lower general cognitive abilities (r = -0.34, p < 0.02), lower verbal comprehension (r = -0.305, p < 0.05), and lower perceptual reasoning scores (r = -0.346, p = 0.02). CONCLUSION The children with type 1 diabetes had a lower serum BDNF level and poorer neurocognitive function than normal healthy children, especially those with GAD65-Ab positive diabetes. Poor glycemic control was correlated with worse cognitive performance.

Abstract
BACKGROUND The effect of prior hypoglycaemia on cognitive function in type 1 diabetes is an important unresolved clinical question. In this systematic review, we aimed to summarize the studies exploring the impact of prior hypoglycaemia on any aspect of cognitive function in type 1 diabetes. METHODS We used a multidatabase search platform Healthcare Database Advanced Search to search Medline, PubMed, EMBASE, EMCARE, CINAHL, PsycINFO, BNI, HMIC, and AMED from inception until 1 May 2019. We included studies on type 1 diabetes of any age. The outcome measure was any aspect of cognitive function. RESULTS The 62 studies identified were grouped as severe hypoglycaemia (SH) in childhood (⩽18 years) and adult-onset (>18 years) diabetes, nonsevere hypoglycaemia (NSH) and nocturnal hypoglycaemia (NH). SH in early childhood-onset diabetes, especially seizures and coma, was associated with poorer memory (verbal and visuospatial), as well as verbal intelligence. Among adult-onset diabetes, SH was associated with poorer cognitive performance in the older age (>55 years) group only. Early versus late exposure to SH had a significant association with cognitive dysfunction (CD). NSH and NH did not have any significant association with CD, while impaired awareness of hypoglycaemia was associated with poorer memory and cognitive-processing speeds. CONCLUSION The effect of SH on cognitive function is age dependent. Exposure to SH in early childhood (<10 years) and older age groups (>55 years) was associated with a moderate effect on the decrease in cognitive function in type 1 diabetes [PROSPERO ID: CRD42019141321].

Abstract
The effect of type 1 diabetes on the developing brain is a topic of primary research interest. A variety of potential dysglycaemic insults to the brain can cause cellular and structural injury and lead to altered neuropsychological outcomes. These outcomes might be subtle in terms of cognition but appear to persist into adult life. Age and circumstance at diagnosis appear to play a substantial role in potential CNS injury. A history of diabetic ketoacidosis and chronic hyperglycaemia appear to be more injurious than previously suspected, whereas a history of severe hypoglycaemia is perhaps less injurious. Neurocognitive deficits manifest across multiple cognitive domains, including executive function and speed of information processing. Some evidence suggests that subtle brain injury might directly contribute to psychological and mental health outcomes. Impaired executive function and mental health, in turn, could affect patients' adherence and the ability to make adaptive lifestyle choices. Impaired executive functioning creates a potential feedback loop of diabetic dysglycaemia leading to brain injury, further impaired executive function and mental health, which results in suboptimal adherence, and further dysglycaemia. Clinicians dealing with patients with suboptimal glycaemic outcomes should be aware of these potential issues.

Abstract
IMPORTANCE Type 1 diabetes has been associated with cardiovascular disease and late complications such as retinopathy and nephropathy. However, it is unclear whether there is an association between type 1 diabetes and school performance in children. OBJECTIVE To compare standardized reading and mathematics test scores of schoolchildren with type 1 diabetes vs those without diabetes. DESIGN, SETTING, AND PARTICIPANTS Population-based retrospective cohort study from January 1, 2011, to December 31, 2015 (end date of follow-up), including Danish public schoolchildren attending grades 2, 3, 4, 6, and 8. Test scores were obtained in math (n = 524 764) and reading (n = 1 037 006). Linear regression models compared outcomes with and without adjustment for socioeconomic characteristics. EXPOSURES Type 1 diabetes. MAIN OUTCOMES AND MEASURES Primary outcomes were pooled test scores in math and reading (range, 1-100). RESULTS Among 631 620 included public schoolchildren, the mean (SD) age was 10.31 (SD, 2.42) years, and 51% were male; 2031 had a confirmed diagnosis of type 1 diabetes. Overall, the mean combined score in math and reading was 56.11 (SD, 24.93). There were no significant differences in test scores found between children with type 1 diabetes (mean, 56.56) and children without diabetes (mean, 56.11; difference, 0.45 [95% CI, -0.31 to 1.22]). The estimated difference in test scores between children with and without type 1 diabetes from a linear regression model with adjustment for grade, test topic, and year was 0.24 (95% CI, -0.90 to 1.39) and 0.45 (95% CI, -0.58 to 1.49) with additional adjustment for socioeconomic status. CONCLUSIONS AND RELEVANCE Among Danish public schoolchildren, there was no significant difference in standardized reading and mathematics test scores of children with type 1 diabetes compared with test scores of children without diabetes.

Abstract
This study examined nonverbal intelligence and scholastic achievement in children with type 1 diabetes. In a retrospective case–control study, 69 children (35 males) ages 5–10 years with type 1 diabetes and 69 healthy controls matched to patients by age, gender and socioeconomic status were compared according to their performance on Raven’s Coloured Progressive Matrices and their scholastic grades. No differences in nonverbal intelligence and grades were observed between children with type 1 diabetes and healthy control subjects. Raven’s Coloured Progressive Matrices scores inversely correlated with duration of illness both in children with early onset of type 1 diabetes and poor metabolic control. Possible explanations of the results and implications are discussed.

Abstract
The purpose of this study is to examine differences in parenting styles between mothers of children with type 1 diabetes and mothers of healthy children and to explore relationships between parenting styles and glycemic control of children with diabetes. Mothers of 63 children with diabetes and mothers of 83 children without diabetes reported their parenting styles using the Blocks' Child Rearing Practices Report, when their child was 9⁻10 years old. Glycemic control of the children with diabetes was evaluated 1 year after diagnosis (<6 years of age) and at the time of the study (at 9⁻10 years). Mothers of children with diabetes used more psychological control than mothers of healthy children. Among girls with diabetes, poorer early glycemic control was associated with mothers' subsequent greater use of psychological control. Behavioral control was positively associated with poorer current glycemic control. In boys, psychological control was positively associated with poorer current glycemic control. Psychological control in families with diabetes needs attention, because it has shown to be associated with poorer diabetes care.

[PMID: 30517159 PMCID: PMC6281208 DOI: 10.1371/journal.pone.0208116] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2018] [Accepted: 11/12/2018] [Indexed: 01/24/2023] Open
Abstract
Aims To investigate while accounting for health at birth 1) associations between health problems during childhood, measured as hospitalizations, and school achievement in the final year of compulsory school, measured as overall grade points and eligibility for upper secondary education, 2) if and how gender moderates the association between health problems and school achievement, 3) if and how the timing of a health problem during childhood is associated with later school achievement. Methods Analyzes were performed on a population-based cohort (n = 115 196) born in 1990 in Sweden (51.3% boys, 48.7% girls) using data from several national registries. Multiple linear regression and logistic regression were used to analyze associations between study variables. Results Overall grade points and eligibility for continuation to upper secondary school were lower for individuals exposed to hospitalizations. Only the association between hospitalizations and overall grade points was moderated by gender and only for ages 13–16 years. Exposure close to actual grading had worst outcomes. Conclusions Health problems, measured through hospitalizations, was significantly associated with lower school achievements among Swedish children. Girls exposed to health problems requiring hospitalizations had relatively poorer school achievements as compared to boys. Health problems requiring hospitalization during junior high school had the greatest negative association with final achievement at compulsory school.

Abstract
Type 1 diabetes mellitus (T1DM) is a major subtype of diabetes and is usually diagnosed at a young age with insulin deficiency. The life expectancy of T1DM patients has increased substantially in comparison with that three decades ago due to the availability of exogenous insulin, though it is still shorter than that of healthy people. However, the relation remains unclear between T1DM and dementia as an aging-related disease. We conducted a systematic review of existing literature on T1DM and cognition impairments by carrying out searches in electronic databases Medline, EMBASE, and Google Scholar. We restricted our review to studies involving only human subjects and excluded studies on type 2 diabetes mellitus or non-classified diabetes. A meta-analysis was first performed on the relationship between T1DM and cognitive changes in youths and adults respectively. Then the review focused on the cognitive complications of T1DM and their relation with the characteristics of T1DM, glycemic control, diabetic complications, comorbidities, and others. First, age at onset, disease duration, and glycemic dysregulation were delineated for their association with cognitive changes. Then diabetic ketoacidosis, angiopathy, and neuropathy were examined as diabetic complications for their involvement in cognitive impairments. Lastly, body mass index and blood pressure were discussed for their relations with the cognitive changes. Future studies are needed to elucidate the pathogenesis of T1DM-related cognitive impairments or dementia.

Abstract
BACKGROUND Support in diabetes self-care in school is essential to achieve optimal school performance and metabolic control. Swedish legislation regulating support to children with chronic diseases was strengthened 2009. OBJECTIVE To compare the results of a national survey conducted 2008 and 2015 measuring parents' and diabetes specialist teams' perceptions of support in school. METHOD All pediatric diabetes centers in Sweden were invited to participate in the 2015 study. In each center, families with a child being treated for T1DM and attending preschool class or compulsory school were eligible. The parents' and the diabetes teams' opinions were collected in two separate questionnaires. RESULTS Forty-one out of 42 eligible diabetes centers participated and 568 parents answered the parental questionnaire in 2015. Metabolic control had improved since the 2008 survey (55.2 ± 10.6 mmol/mol, 7.2% ± 1.0%, in 2015 compared with 61.8 ± 12.4 mmol/mol, 7.8% ± 1.1% in 2008). The proportion of children with a designated staff member responsible for supporting the child's self-care increased from 43% to 59%, (P < .01). An action plan to treat hypoglycemia was present for 65% of the children in 2015 compared with 55% in 2008 (P < .01). More parents were satisfied with the support in 2015 (65% compared with 55%, P < .01). CONCLUSIONS This study shows that staff support has increased and that more parents were satisfied with the support for self-care in school in 2015 compared with 2008. More efforts are needed to implement the national legislation to achieve equal support in all Swedish schools.

Abstract
The health problems related to the nervous system are on rise in young infants leading to high mortality amongst this age group. A chronic medical condition (CC) is present in this age group to the tune of 10–20%. We searched the electronic database PubMed for pre-clinical as well as clinical controlled trials reporting variable chronic conditions especially in pediatric patients. Most of these reports revealed that type 1 diabetes mellitus is the most common CC in young infants. In female patients, metabolic control is often disturbed during CC in this age group. Poor metabolism regulation often results in long-term complications, including cognitive disorders. In cognitive disorders, memory loss and learning problems are the most among adolescents. Executive problems are observed to be associated with low physical activities. The review article concludes that knowledge about factors influencing treatment adherence is crucial in chronically ill infants. Further, we should focus on protective factors in order to prevent health risk behavior.

Abstract
The relation between metabolic control (HbA1c) and achievement (grade point average [GPA]) was examined over a period of 2.5 years (every 6 months) employing a dynamical systems approach that allowed for the examination of whether HbA1c was associated with change in subsequent GPA and vice versa. Metabolic control tends to deteriorate (i.e., with higher HbA1c reflecting poorer metabolic control) during adolescence. It was hypothesized that these higher levels of HbA1c would limit subsequent increases in GPA. The sample included 252 adolescents (Mbaseline age = 12.49 years, SD = 1.53; 53.6% female) with Type 1 diabetes. Mothers' report and school records provided information on relevant demographics and GPA; medical records provided values of HbA1c. Two simultaneous coupled change equations (i.e., examining current values in 1 variable associated with changes in the other) controlling relevant risk indicators (i.e., age, sex, disease duration, insulin delivery method, IQ) revealed higher levels of HbA1c limited increases in GPA. Higher levels of GPA, however, were not associated with change in HbA1c except for 2 instances where moderation existed by disease duration and IQ. Higher GPA was associated with slower increases in HbA1c over time for youth with shorter disease duration and lower IQ. These results affirm the importance of maintaining good metabolic control to facilitate adequate school performance across the adolescent years. Further, the results suggest that factors related to school achievement may protect adolescents who are newly diagnosed or who have low cognitive ability from subsequent deterioration in metabolic control.

Abstract
AIMS To determine if children and young people aged < 23 years with Type 1 diabetes differ in academic ability from age-matched control subjects without Type 1 diabetes and whether academic scores are related to glycaemic control. METHODS Using a cross-sectional study design, we administered cognitive and academic tests (Woodcock-Johnson III Spatial Relations, General Information, Letter-Word Recognition, Calculation and Spelling tests) to young people with Type 1 diabetes (n=61) and control subjects (n=26) aged 9-22 years. The groups did not differ in age or gender. Participants with Type 1 diabetes had a disease duration of 5-17.7 years. History of glycaemic control (HbA1c , diabetic ketoacidosis and severe hypoglycaemic episodes) was obtained via medical records and interviews. RESULTS The participants with Type 1 diabetes had a lower mean estimated verbal intelligence (IQ) level compared with those in the control group (P=0.04). Greater exposure to hyperglycaemia over time was associated with lower spelling abilities within the group with Type 1 diabetes (P=0.048), even after controlling for age, gender, socio-economic status, blood glucose level at time of testing and verbal IQ (P=0.01). History of severe hypoglycaemia or ketoacidosis was not associated with differences in academic abilities. CONCLUSIONS In children and young people, Type 1 diabetes was associated with a lower verbal IQ. Moreover, increased exposure to hyperglycaemia was associated with lower spelling performance. These results imply that hyperglycaemia can affect cognitive function and/or learning processes that may affect academic achievement.

Abstract
BACKGROUND Type 1 diabetes may be associated with structural and functional alterations in the brain. The role of diabetic ketoacidosis (DKA) in causing these alterations has not been well explored. METHODS We used immunohistochemical staining to investigate cellular alterations in brain specimens from juvenile rats with DKA before, during, and after treatment with insulin and saline, and compared these to samples from diabetic rats and normal controls. RESULTS Glial fibrillary acidic protein (GFAP) staining intensity was increased in the hippocampus during DKA and increased further during insulin/saline treatment. Twenty-four and 72 h after treatment, hippocampal GFAP intensity declined but remained above control levels. There were no significant changes in GFAP intensity in the cortex or striatum. OX42 staining intensity was increased during untreated DKA and increased further during insulin/saline treatment in the hippocampus and cortex. NeuN staining intensity was decreased after DKA treatment in the striatum but not in other regions. CONCLUSIONS DKA causes inflammatory changes in the brain including reactive gliosis and activation of microglia. These findings are present during untreated DKA, but intensify during insulin/saline treatment. The hippocampus was disproportionately affected, consistent with previous studies showing deficits in hippocampal functions in rats after DKA recovery and decreased memory capacity in children with a history of DKA.

Abstract
AIM Few studies have focused on the psychological adjustment of pre-adolescent children with type 1 diabetes. This study examined psychosocial functioning in nine- and 10-year-old children with early-onset type 1 diabetes, and their mothers, and associations between psychosocial functioning and diabetes management. METHODS The mothers of 63 children with early-onset diabetes and 86 healthy children evaluated their own psychosocial functioning, and their child's, with standardised rating scales. We used general linear models to analyse the children's behaviour problems and the mothers' well-being. Associations between the children's behaviour problems, diabetes-related measures and the mothers' well-being were studied with partial correlations. RESULTS Children with diabetes had more internalising problems than the controls (p = 0.001), and these were associated with poor glycaemic control at the early stage of the illness (p = 0.033) and the use of insulin pumps in girls (p = 0.004). Mothers in the diabetes group had more child-related stress than the controls (p < 0.001), and poorer well-being was associated with the children's behavioural problems (p < 0.024). CONCLUSION Children with early-onset diabetes faced an increased risk of internalising problems in middle childhood. The mothers' psychological distress was associated with children's behaviour problems rather than their diabetes.

Abstract
OBJECTIVE To investigate the prevalence of severe hypoglycemia in Danish children and adolescents with type 1 diabetes and to pinpoint predictors of this acute complication in children on modern treatment modalities. RESEARCH DESIGN AND METHODS The study is based on data from DanDiabKids, a national diabetes register for children and adolescents. The register contains data on patients with type 1 diabetes with an ascertainment rate of 99%. Data from 3320 patients aged 0-18 yr was included in the study period from 1998 to 2009 and analyzed using a negative binomial model. RESULTS One thousand nine hundred and ninety-nine episodes of severe hypoglycemia in 867 patients were registered conferring an overall incidence of severe hypoglycemia of 15.1 [95% confident interval (CI): 13.8; 16.4] per 100 patient years. This remained unchanged during the study period. Duration of diabetes, age and treatment in centers managing less than 100 patients significantly increased the risk of severe hypoglycemia (p < 0.001). Patients on insulin pump therapy had a 42% reduced risk of severe hypoglycemia compared with pen treated patients (p = 0.01). Patients treated with five or more daily insulin injections had a 31% (95% CI: 17; 49) reduced risk of severe hypoglycemia compared to patients on fewer daily injections (p = 0.015). CONCLUSIONS Despite improvements in metabolic control over a decade the prevalence of severe hypoglycemic events remained unchanged. More intensive treatments such as insulin pump therapy and multiple daily injections on a national level seems to be a protective factor for developing severe hypoglycemia up to 2009.

Abstract
A constant supply of glucose to the brain is critical for normal cerebral metabolism. The dysglycemia of type 1 diabetes (T1D) can affect activity, survival, and function of neural cells. Clinical studies in T1D have shown impairments in brain morphology and function. The most neurotoxic milieu seems to be young age and/or diabetic ketoacidosis at onset, severe hypoglycemia under the age of 6 years followed by chronic hyperglycemia. Adverse cognitive outcomes seem to be associated with poorer mental health outcomes. It is imperative to improve outcomes by investigating the mechanisms of injury so that neuroprotective strategies independent of glycemia can be identified.

Abstract
Aim: To evaluate the social performance of young adults with type 1 diabetes (T1D) since childhood with particular interest in its relation to the severity of diabetic retinopathy (DR). Methods: The prevalence of DR was evaluated in a population-based Finnish cohort of children with T1D during 1989–1990. The subjects were contacted 18 years later for evaluation of DR, education, employment, and family relations. Results: 136 of 216 subjects participated in the study in 2007 (mean age 30±3 years, mean diabetes duration 23±4 years, 78 men). There were 42 subjects (31%) with proliferative diabetic retinopathy (PDR). A university degree was held by 9%, a degree from a university of applied sciences by 33%, and 45% had a vocational school education; 7% were full-time students while 4% had received no education after comprehensive school. PDR was associated with lower education. Sixty percent of the subjects with PDR and 68% of those with non-PDR held full-time jobs. Four percent of the non-PDR group were unemployed while 26% of subjects with PDR were outside working life because of either unemployment or retirement. Seventy-one percent of the subjects had a spouse, and 60 subjects had a total of 119 children. PDR did not compromise the likelihood of having a spouse and children. Conclusions: The majority of young adults with T1D take active roles in society by working and raising families. However, patients with PDR lacked secondary education significantly more often and were less likely to work than those with non-PDR.

Abstract
Type 1 diabetes mellitus (T1DM) is one of the most prevalent chronic conditions affecting individuals under the age of 18 years, with increasing incidence worldwide, especially among very young age groups, younger than 5. There is still no cure for the disease, and therapeutic goals and guidelines are a challenge. Currently, despite T1DM intensive management and technological interventions in therapy, the majority of pediatric patients do not achieve glycemic control goals. This leads to a potential prognosis of long term diabetic complications, nephrological, cardiac, ophthalmological and neurological. Unfortunately, the neurological manifestations, including neurocognitive and behavioral complications, may present soon after disease onset, during childhood and adolescence. These manifestations may be prominent, but at times subtle, thus they are often not reported by patients or physicians as related to the diabetes. Furthermore, the metabolic mechanism for such manifestations has been inconsistent and difficult to interpret in practical clinical care, as reported in several reviews on the topic of brain and T1DM. However, new technological methods for brain assessment, as well as the introduction of continuous glucose monitoring, provide new insights and information regarding brain related manifestations and glycemic variability and control parameters, which may impact the clinical care of children and youth with T1DM. This paper provides a comprehensive review of the most recently reported behavioral, cognitive domains, sleep related, electrophysiological, and structural alterations in children and adolescences from a novel point of view. The review focuses on reported impairments based on duration of T1DM, its timeline, and modifiable disease related risk parameters. These findings are not without controversy, and limitations of data are presented in addition to recommendations for future research direction.

J Diabetes 2014; 6:499-513. [PMID: 25042689 DOI: 10.1111/1753-0407.12193] [Citation(s) in RCA: 92] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2013] [Revised: 05/07/2014] [Accepted: 06/29/2014] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Type 1 diabetes (T1D) can have a significant impact on brain structure and function, which is referred to as T1D-associated cognitive decline (T1DACD). Diabetes duration, early onset disease, and diabetes-associated complications are all proposed as factors contributing to T1DACD. However, there have been no comparisons in T1DACD between children and adults with T1D. To obtain a better insight into the occurrence and effects of T1DACD in T1D, the aim of the present meta-analysis was to investigate differences between children and adults and to analyse factors contributing T1DACD. METHODS Two electronic databases were consulted: PubMed and ISI Web of Knowledge. Literature published up until the end of 2013 was included in the analysis. Effect sizes (Cohen's d), which are standardized differences between experimental and control groups, were calculated. RESULTS There was a small to modest decrease in cognitive performance in T1D patients compared with non-diabetic controls. Children with T1D performed worse while testing for executive function, full intelligence quotient (IQ), and motor speed, whereas adults with T1D performed worse while testing the full, verbal and performance IQ, part of the executive function, memory, spatial memory, and motor speed. Episodes of severe hypoglycemia, chronic hyperglycemia, and age of onset can be significant factors influencing cognitive function in T1D. CONCLUSIONS The findings in the literature suggest that T1DACD is more severe in adults than children, indicating that age and diabetes duration contribute to this T1DACD.

Abstract
The adult brain accounts for a disproportionally large percentage of the body’s total energy consumption (1). However, during brain development,energy demand is even higher, reaching the adult rate by age 2 and increasing to nearly twice the adult rate by age 10, followed by gradual reduction toward adult levels in the next decade (1,2). The dramatic changes in brain metabolism occurring over the first two decades of life coincide with the initial proliferation and then pruning of synapses to adult levels.The brain derives its energy almost exclusively from glucose and is largely driven by neuronal signaling, biosynthesis, and neuroprotection (3–6).Glucose homeostasis in the body is tightly regulated by a series of hormones and physiologic responses. As a result, hypoglycemia and hyperglycemia are rare occurrences in normal individuals, but they occur commonly inpatients with type 1 diabetes mellitus (T1DM) due to a dysfunction of peripheral glucose-insulin-glucagon responses and non-physiologic doses of exogenous insulin, which imperfectly mimic normal physiology. These extremes can occur more frequently in children and adolescents with T1DM due to the inadequacies of insulin replacement therapy, events leading to the diagnosis [prolonged untreated hyperglycemia and diabetic ketoacidosis (DKA)], and to behavioral factors interfering with optimal treatment. When faced with fluctuations in glucose supply the metabolism of the body and brain change dramatically, largely to conserve resources and, at a cost to other organs, to preserve brain function (7). However,if the normal physiological mechanisms that prevent these severe glucose fluctuations and maintain homeostasis are impaired, neuronal function and potentially viability can be affected (8–11).

Abstract
Objective To examine the effect of type 1 diabetes on academic performance. Methods Ethnically Saudi students with type 1 diabetes, and age, sex, ethnicity and socio-economic status-matched nondiabetic control students were recruited from eight schools. Overall academic grades were recorded, based on the scores obtained in written examinations in English, mathematics, physics, chemistry, biology and humanities. Results Students with type 1 diabetes ( n = 36) obtained significantly lower academic grades compared with their nondiabetic control classmates ( n = 36) (86.58 ± 1.48 vs 90.62 ± 1.36). Conclusions Overall academic performance is significantly lower in students with type 1 diabetes compared with their nondiabetic classmates. This decline in academic performance may be explained by an association between diabetes and cognitive function.
