Childhood Predictors

Objective: The study aimed to identify early childhood risk factors for de novo and subthreshold late-onset ADHD. Method: ADHD symptoms were assessed in 9,875 participants from the Twins Early Development Study (TEDS) using the Conners’ Parent Rating Scale at ages 8, 12, 14, and 16 years, along with other childhood characteristics and adolescent outcomes. Multinomial logistic regressions were implemented to identify early childhood predictors of late-onset ADHD and childhood-onset persistent ADHD, with non-ADHD controls as the reference category. Results: Male sex, increased childhood conduct problems, and low socioeconomic status predicted de novo late-onset ADHD. Additional risk factors predicted subthreshold late-onset ADHD and childhood-onset persistent ADHD. Late-onset ADHD symptoms were also accompanied by increased co-occurring behavioral and emotional problems. Conclusion: Findings of different childhood predictors between subthreshold and de novo late-onset ADHD suggest further investigation into time-varying environmental and biological factors driving psychopathological changes is warranted to fully characterize late-onset ADHD.

Abstract Background Attention-deficit hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders, affects 5% of children worldwide and characterized by impaired inattention, hyperactivity and impulsivity. One of the risk factors that precipitate ADHD is food. Food affects behavior of children by different ways such as food allergy, food intolerance and gut–microbiota–brain axis. The study aimed to assess effect of diet modification on ADHD outcome and the role of food as a precipitating factor for ADHD symptomatology. The study included 47 children newly diagnosed with ADHD, not receiving medical or behavioral therapy, their ages ranged from 6 to 9 years and their intelligence quotient not below 70 with no associated comorbidities. All participants were subjected to Full history taking, clinical examination, anthropometric measurements, 24 h dietary recall. Dietary analysis and Conner’s parent rating scale-revised short form (CPR-RS) were done before and after diet modification program for 5 weeks. Results There was improvement in ADHD symptoms as measured by CPR-RS after 5-weeks of diet modification program. Carbohydrate and protein intake decreased significantly after diet modification program. Energy intake did not show statistical difference while fat intake increased significantly after the diet program. Vitamin A, C, riboflavin, thiamin and iron intakes decreased significantly after diet program but were within the recommended dietary allowance. Conclusion Following the Diet modification program, ADHD symptoms were improved as documented by decrease in CPR scores. Diminished carbohydrate and protein intake in diet were positively associated with improvement of ADHD symptoms. Diet modification program succeeded in reducing obesity and then ADHD symptoms.

AbstractImportanceKnowledge of the mechanisms underlying the intergenerational transmission of risk for attention-deficit/hyperactivity disorder (ADHD) symptoms can inform psychosocial interventions.ObjectiveTo investigate whether parental genetic risk factors associate with their children’s ADHD symptoms due to genetic transmission of risk or due to parental genetic liability that influences offspring ADHD via parenting environments (genetic nurture).Design and participantsThis study is based on the Norwegian Mother, Father and Child Cohort Study and uses data from the Medical Birth Registry of Norway. This prospective cohort study consisted of 5,405 mother-father-offspring trios recruited between 1999 – 2008.ExposuresWe calculated polygenic scores for parental traits previously associated with ADHD, including psychopathology, substance use, neuroticism, educational attainment and intellectual ability.Main outcomes and measuresMothers reported on their 8-year-old children’s ADHD symptoms using the Parent/Teacher Rating Scale for Disruptive Behavior Disorders.ResultsMaternal polygenic scores for ADHD, autism spectrum disorder (ASD), neuroticism and smoking predicted child ADHD symptoms in bivariate analyses. After jointly modelling maternal, paternal and child polygenic scores, ADHD symptoms were predicted by children’s polygenic scores for ADHD (β = 0.10; 95% CI 0.07 to 0.14), smoking (β = 0.07; 95% CI 0.03 to 0.10) and educational attainment (β = −0.09; 95% CI −0.13 to −0.05), indicating direct genetic transmission of risk. Mothers’ polygenic scores for ASD (β = 0.05; 95% CI 0.02 to 0.08) and neuroticism (β = 0.05; 95% CI 0.01 to 0.08) predicted children’s ADHD symptoms conditional on fathers’ and children’s scores, implicating genetic nurture, or effects due to population stratification or assortative mating.ConclusionsThese results suggest that associations between some parental traits and offspring ADHD symptoms likely reflect a nuanced mix of direct genetic transmission (ADHD, smoking and educational attainment) and genetic nurture (ASD and neuroticism). If confirmed, these findings support previous evidence that maternal ASD or neuroticism may be possible targets for intervention to help break the chain of the intergenerational transmission of ADHD risk.

Epilepsy affects 1 out of every 26 people during their lifetime. Worldwide, the incidence of epilepsy ranges from 28.0/100,000 to 235.5/100,000, with the large variation attributable to differences in methodology across studies. The prevalence of active epilepsy provides important information about the burden of epilepsy in the population and spurs public health planner to assess the needs of the epilepsy population. The active prevalence of epilepsy ranges from 2.4/1,000 to 22.8/1,000 worldwide and more than 65 million people have active epilepsy. Risk factors for childhood-onset and adult-onset epilepsy are discussed, considering epilepsy etiologies (e.g., severe traumatic brain injury), newer risk factors without bidirectional relationships with epilepsy (e.g., low socioeconomic status), risk factors with bidirectional relationships (e.g., psychiatric disorders), and different types of acute symptomatic seizures (e.g., febrile seizures).

Objectives: We wanted to determine: (1) whether ADHD symptoms were more common in mothers of children with ADHD; (2) whether mothers of children with ADHD differed in their parenting strategies; and (3) whether there was a difference in care-giving arrangements for children with ADHD and without ADHD. This was done by comparing mothers of children with ADHD with mothers of children without ADHD in Singapore. Methods: Mothers of children with ADHD ( n=46) and mothers of children without ADHD ( n=45) completed the Conners’ Parent Rating Scale-Revised, the Conners’ Adult ADHD Rating Scale-Self Report and the Alabama Parenting Questionnaire. Results: Mothers of children with ADHD did not report higher levels of current ADHD symptoms compared with the control group. However, they did use less adaptive parenting strategies. There were also no differences in the reported behaviours of children cared for by a paid worker and those cared for by mothers. Conclusions: Data support the Singapore Clinical Guidelines recommendations for the promotion of parenting skills, and referral to parenting programmes for parents of children with ADHD. The promotion of parenting skills and referral to parenting programmes for mothers of children with ADHD might include the option of electronic forms of programme delivery. The model of using paid help in the home, which is commonplace in Singapore, does not seem to disadvantage children with ADHD.

Background: Apathy has been shown to be an important feature of degenerative, vascular or traumatic brain disorder. Its presence is associated with high depression scores, higher age, low performance on frontal tasks, and more severe deep white matter hyperintensities. In late-life depression, lack of interest or motivation are often more prominent than depressed mood, especially in the late-onset type. It was hypothesized that in a heterogeneous sample of elderly depressed patients, apathy is associated with late-onset type of depression, cognitive dysfunction or vascular risk factors.Method: The Apathy Evaluation Scale (AES) was administered to twenty-nine elderly (≥60 years) inpatients with a DSM-IV major depression or dysthymic disorder. The severity of the depression was measured with the Montgomery-Åsberg Depression Rating Scale (MADRS) and cognitive function with the Mini-mental State Examination (MMSE). The presence of vascular risk factors was traced in the patient's medical records.Results: Apathy was found in 86% of the patients. The AES-score was correlated with the negative symptom score, but not with total MADRS or MMSE-score. No difference in AES-score between early-onset depressed (n = 16) and late-onset depressed (n = 13) patients was found, and between patients with or without vascular risk.Conclusion: Apathy is a main feature of moderate to severe depressive illness in elderly patients and related to the negative symptoms of the disorder. Further studies should include less severely depressed patients and investigate the relation between depression severity and apathy.

Objective. To evaluate the short-term efficacy and side effects associated with two methylphenidate hydrochloride (MPH) dosing patterns. Methods. Twenty-five boys with attention deficit hyperactivity disorder (ADHD) participated in a 5-week, triple-blind, placebo-controlled, crossover evaluation of MPH administered twice (b.i.d.) versus thrice (t.i.d.) per day (mean dose 8.8 ± 5 mg, .30 ± .1 mg/kg/dose). Four dosing conditions (placebo, titration [gradual increase to target dose], b.i.d., and t.i.d.) were used. Dependent measures obtained on a weekly basis included: parent and teacher ratings of child behavior, parent-child conflicts, parent report of stimulant side effects, child self-report of mood symptoms, a sleep log, laboratory measures of attention, and actigraphic recording of sleep activity. Results. All dosing conditions resulted in significant effects on ADHD symptoms when compared with baseline. Relative to placebo, t.i.d. dosing was characterized by improvement on the greatest number of behavioral measures, and both b.i.d. and t.i.d. were generally more effective than titration. Direct comparisons of b.i.d. and t.i.d. dosing revealed that t.i.d. was associated with greater improvement on the Conners Parent Rating Scale Impulsivity/Hyperactivity factor, with a similar marginally significant effect for the ADD-H Teacher Rating Scale Hyperactivity factor. The analysis of clinically significant change favored a three-times-a-day dosing schedule over placebo on both parent and teacher ratings of impulsivity/hyperactivity and attention. Compared with placebo, appetite suppression was rated, on average, as more severe in the t.i.d. and titration conditions, but not in the b.i.d condition. However, the number of subjects who exhibited any or severe appetite suppression did not differ significantly between the b.i.d. and t.i.d. schedules. Although there was no difference in sleep duration for children on b.i.d. and t.i.d. schedules, total sleep time appeared to decrease slightly on t.i.d. relative to placebo according to both parent ratings and actigraphic assessment. There were no significant differences between b.i.d. and t.i.d. on any other side effects or sleep variables. Conclusions. For many children with ADHD, t.i.d. dosing may be optimal. There are few differences in acute side effects between b.i.d and t.i.d. MPH dosing. The dosing schedule should be selected according to the severity and time course of ADHD symptoms rather than in anticipation of dosing schedule-related side effects.

BACKGROUND: Over the last decades, the hypothesis that an allergic response could lead to the development of attention-deficit/hyperactivity disorder (ADHD) was raised and clinical studies investigated the co-existence of both. These studies had shown that allergic diseases and neurobehavioral disorders were concurrent and could be associated with genetic factors, neuroimmunity and microbial dysbiosis. To date, this was the first study in the Philippines to evaluate the prevalence and association of allergic diseases, its severity and ADHD symptoms. OBJECTIVE: The objective of this study was to determine the association of allergic diseases and ADHD symptoms among children aged 6–12 years based on parental report using the Filipino version of the Vanderbilt ADHD Parent Rating Scale. METHODS: School-aged children between 6 and 12 years with physician diagnosed allergies (bronchial asthma, allergic rhinitis, atopic dermatitis, allergic conjunctivitis, drug allergy, food allergy and/or acute or chronic urticaria) were randomly selected. Skin prick test (SPT) to aeroallergens was done. The parents completed the Filipino version of the Vanderbilt ADHD Diagnostic Parent Rating Scale (VADPRS), a screening tool for ADHD. RESULTS: Among the 415 patients, 135 (32.5%) of them screened positive for ADHD symptoms. Upon assessment of the Vanderbilt parent rating subscale responses, 13.49% of the children were categorized as predominantly inattentive subtype, 6.02% as predominantly hyperactive/impulsive subtype and 13.01% as combined inattention/hyperactivity. Three hundred and seventy six (91%) children were diagnosed with asthma. Among these asthmatics, 119 (32%) had ADHD symptoms with the following subtypes – predominantly inattentive subtype (13.56%), predominantly hyperactive/impulsive subtype (5.05%) and combined inattention/hyperactivity (13.03%). Combined inattention/hyperactivity subtype had a significant proportion of severe asthmatics, as compared to mild or moderate asthma (p value = 0.026). Furthermore, 389 (94%) children were diagnosed with allergic rhinitis. Among these patients, 130 (33%) had ADHD symptoms with the following subtypes – predominantly inattentive subtype (13.62%), predominantly hyperactive/impulsive subtype (6.43%) and combined inattention/hyperactivity (13.37%). However, evidence was not sufficient to demonstrate an association between ADHD subtypes and allergic rhinitis severity. Lastly, 206 (50%) children were diagnosed with atopic dermatitis. Among these patients, 71 (34%) had ADHD symptoms with the following subtypes – predominantly inattentive subtype (14.56%), predominantly hyperactive/impulsive subtype (4.85%) and combined inattention/hyperactivity (15.05%). However, there was insufficient evidence to demonstrate a link between ADHD subtypes and atopic dermatitis severity. CONCLUSION: Children with allergies, especially those with severe asthma, are more likely to have ADHD symptoms.

This study examines the prevalence of loneliness amongst older people in Great Britain, and makes comparisons with the findings of studies undertaken during the last five decades. In addition, the risk factors for loneliness are examined using a conceptual model of vulnerability and protective factors derived from a model of depression. Loneliness was measured using a self-rating scale, and measures of socio-demographic status and health/social resources were included. Interviews were undertaken with 999 people aged 65 or more years living in their own homes, and the sample was broadly representative of the population in 2001. Among them the prevalence of ‘severe loneliness’ was seven per cent, indicating little change over five decades. Six independent vulnerability factors for loneliness were identified: marital status, increases in loneliness over the previous decade, increases in time alone over the previous decade; elevated mental morbidity; poor current health; and poorer health in old age than expected. Advanced age and possession of post-basic education were independently protective of loneliness. From this evidence we propose that there are three loneliness pathways in later life: continuation of a long-established attribute, late-onset loneliness, and decreasing loneliness. Confirmation of the different trajectories suggests that policies and interventions should reflect the variability of loneliness in later life, for undifferentiated responses may be neither appropriate nor effective.

AbstractWe investigated to what extent parent-rated attention-deficit/hyperactivity disorder (ADHD) and impairment at age 3 years predicted elevated ADHD symptoms at age 5 years, and whether teacher-rated ADHD symptoms improved these predictions. This study is part of the longitudinal, population-based Norwegian Mother, Father and Child Cohort Study. Parents of 3-year-old children (n = 1195) were interviewed about ADHD and impairment, and teachers rated child ADHD symptoms by the Strengths and Difficulties Questionnaire or the Early Childhood Inventory-4. At 5 years of age, the children (n = 957) were classified as ADHD-positive or -negative using Conners’ Parent Rating Scale. Relying solely on parent-rated ADHD or impairment at age 3 years did moderately well in identifying children with persistent elevation of ADHD symptoms, but gave many false positives (positive predictive values (PPVs): .40–.57). A small group of children (n = 20, 13 boys) scored above cut-off on both parent-rated ADHD and impairment, and teacher-rated ADHD symptoms, although adding teacher-rated ADHD symptoms slightly weakened the predictive power for girls. For this small group, PPVs were .76 for boys and .64 for girls. Limiting follow-up to these few children will miss many children at risk for ADHD. Therefore, we recommend close monitoring also of children with parent-reported ADHD symptoms and/or impairment to avoid delay in providing interventions. Clinicians should also be aware that teachers may miss ADHD symptoms in preschool girls.
