INCLEN diagnostic tool for attention deficit hyperactivity disorder (INDT-ADHD): development and validation

Scalable Transdiagnostic Early Assessment of Mental Health (STREAM): a study protocol

INTRODUCTION

Early childhood development forms the foundations for functioning later in life. Thus, accurate monitoring of developmental trajectories is critical. However, such monitoring often relies on time-intensive assessments which necessitate administration by skilled professionals. This difficulty is exacerbated in low-resource settings where such professionals are predominantly concentrated in urban and often private clinics, making them inaccessible to many. This geographic and economic inaccessibility contributes to a significant 'detection gap' where many children who might benefit from support remain undetected. The Scalable Transdiagnostic Early Assessment of Mental Health (STREAM) project aims to bridge this gap by developing an open-source, scalable, tablet-based platform administered by non-specialist workers to assess motor, social and cognitive developmental status. The goal is to deploy STREAM through public health initiatives, maximising opportunities for effective early interventions.

METHODS AND ANALYSIS

The STREAM project will enrol and assess 4000 children aged 0-6 years from Malawi (n=2000) and India (n=2000). It integrates three established developmental assessment tools measuring motor, social and cognitive functioning using gamified tasks, observation checklists, parent-report and audio-video recordings. Domain scores for motor, social and cognitive functioning will be developed and assessed for their validity and reliability. These domain scores will then be used to construct age-adjusted developmental reference curves.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from local review boards at each site (India: Sangath Institutional Review Board; All India Institute of Medical Science (AIIMS) Ethics Committee; Indian Council of Medical Research-Health Ministry Screening Committee; Malawi: College of Medicine Research and Ethics Committee; Malawi Ministry of Health-Blantyre District Health Office). The study adheres to Good Clinical Practice standards and the ethical guidelines of the 6th (2008) Declaration of Helsinki. Findings from STREAM will be disseminated to participating families, healthcare professionals, policymakers, educators and researchers, at local, national and international levels through meetings, academic journals and conferences.

Effectiveness of structured physiotherapy in constipation in children with neurodevelopmental disorders-a randomized trial

INTRODUCTION

Constipation is one of the major issues faced by children with neuro-developmental disorder (NDD). The aims of the study were to: 1) examine the effectiveness of a structured physiotherapy program on constipation in children with NDD; and 2) compare if conventional physiotherapy along with structured physiotherapy intervention has any combined effect on constipation in children with NDD.

METHOD

Thirty-five children with neurodevelopmental disorder were assessed and randomly allotted into two groups. Twenty-two completed the intervention for 2 weeks and were statistically analyzed at baseline and post 4 weeks at a single tertiary center. The outcome measures used were Pediatric quality of life inventory (PedsQL), Peds QL Gastrointestinal symptoms scale, Bristol stool form scale, and defecation frequency. Group A received the conventional treatment, whereas group B received structured physiotherapy along with the conventional treatment.

RESULTS

Group A had no significant outcomes, whereas in group B there were statistically significant differences for all outcome measures. Comparatively, a statistically significant change was noted for PedsQL GI symptoms scale (p = .045) and its constipation sub-scale (p = .002) in group B along with change in the Bristol stool form.

CONCLUSION

Combined effect of structured along with conventional physiotherapy was better in terms of form of stool, constipation, and its associated quality of life factors as compared to conventional physiotherapy alone.

Altered cerebellar lobular volumes correlate with clinical deficits in siblings and children with ASD: evidence from toddlers

BACKGROUND

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by impaired social and communication skills, narrow interests, and repetitive behavior. It is known that the cerebellum plays a vital role in controlling movement and gait posture. However, recently, researchers have reported that the cerebellum may also be responsible for other functions, such as social cognition, reward, anxiety, language, and executive functions.

METHODS

In this study, we ascertained volumetric differences from cerebellar lobular analysis from children with ASD, ASD siblings, and typically developing healthy controls. In this cross-sectional study, a total of 30 children were recruited, including children with ASD (N = 15; mean age = 27.67 ± 5.1 months), ASD siblings (N = 6; mean age = 17.5 ± 3.79 months), and typically developing children (N = 9; mean age = 17.67 ± 3.21 months). All the MRI data was acquired under natural sleep without using any sedative medication. We performed a correlation analysis with volumetric data and developmental and behavioral measures obtained from these children. Two-way ANOVA and Pearson correlation was performed for statistical data analysis.

RESULTS

We observed intriguing findings from this study, including significantly increased gray matter lobular volumes in multiple cerebellar regions including; vermis, left and right lobule I-V, right CrusII, and right VIIb and VIIIb, respectively, in children with ASD, compared to typically developing healthy controls and ASD siblings. Multiple cerebellar lobular volumes were also significantly correlated with social quotient, cognition, language, and motor scores with children with ASD, ASD siblings, and healthy controls, respectively.

CONCLUSIONS

This research finding helps us understand the neurobiology of ASD and ASD-siblings, and critically advances current knowledge about the cerebellar role in ASD. However, results need to be replicated for a larger cohort from longitudinal research study in future.

Intermediate-term neurodevelopmental outcomes and quality of life after arterial switch operation beyond early neonatal period

OBJECTIVES

The study objective was to evaluate the cardiac, neurodevelopmental, psycho-social and health-related quality of life (HRQOL) outcomes of children who underwent an arterial switch operation (ASO).

METHODS

Children who underwent ASO were evaluated on follow-up at 3-5 years with cardiovascular, neurodevelopmental and HRQOL assessment using validated tools. Children with developmental delay, attention-deficit hyperactivity disorder, autism spectrum disorder, neuromotor and speech and language impairment were considered to have neurodevelopmental disorder (NDD). The impact of socioeconomic status (Kuppuswamy classification), perioperative cardiac, nutritional and psycho-social factors on outcomes was analysed.

RESULTS

There were 61 (89.7%) survivors at a mean follow-up of 50.9 ± 7.6 months. The median age at surgery was 41 days (22-74.5). One-third of patients had growth restriction. Two children had residual cardiovascular lesions requiring intervention. The mean HRQOL score was >90 in all scales of the Paediatric Quality of Life Inventory™ 3.0 Cardiac Module. Neurological abnormalities were seen in 19 patients (31.1%) of whom 17 (27.9%) patients had NDD and 12 had developmental delay. Speech and language impairment, attention-deficit hyperactivity disorder, and neuromotor impairment were found in 16.4%, 3.3% and 6.7% patients, respectively. On multivariate analysis, increasing time to lactate normalization and low socioeconomic status were associated with developmental delay after ASO.

CONCLUSIONS

While intermediate-term cardiac outcomes and HRQOL after ASO were fairly satisfactory, NDD was identified in one-fourth of these children. Increasing time to lactate normalization after ASO and low socioeconomic status were associated with suboptimal intermediate neurodevelopment outcomes after ASO.

The Development and Validation of DSM 5-Based AIIMS-Modified INDT ADHD Tool for Diagnosis of ADHD: A Diagnostic Test Evaluation Study

BACKGROUND

The current study was planned at a tertiary centre in northern India to develop and validate a Diagnostic and Statistical Manual-5 (DSM-5)-based diagnostic tool and design a severity score for attention deficit hyperactivity disorder (ADHD) in children aged 6-18 years. An existing DSM-IV-based tool, INDT (International Clinical Epidemiology Network [INCLEN] diagnostic tool) for ADHD has been modified and named All India Institute of Medical Sciences (AIIMS)-modified INDT ADHD tool.

METHOD

The first phase was development of the tool and the second phase was validation of the same against the gold standard of diagnosis by the DSM-5. A severity score was developed for ADHD in concordance with the Conners rating scale.

RESULTS

The tool was validated in 66 children with a sensitivity and specificity of 100 per cent and 90 per cent, respectively. A cut-off score of 12 was decided for labelling severity of ADHD, which corresponded to 63 in the Conners rating scale.

CONCLUSION

This diagnostic tool for ADHD based on DSM-5 has acceptable psychometric properties. The severity score will be useful for prognostication, monitoring treatment response, and designing intervention trials.

A systematic review of tools used to screen and assess for externalising behaviour symptoms in low and middle income settings

BACKGROUND

Mental health issues, often manifested as behavioural difficulties, in children are estimated to be high in low and middle-income countries (LMIC) settings. There is a paucity of definitive data due to a lack of well-validated tools to use across settings. This review aims to provide evidence on what tools are used and which have been adapted and validated in LMIC settings.

METHODS

We performed a systematic review to identify tools used to assess or screen externalising behaviour problems in children and adolescents in LMIC and assess their cultural adaptations. We searched for studies measuring externalising behaviour in children from 0 to 19 years published up to September 2018. Articles were assessed to identify tools used and analysed using the Ecological Validity Framework.

RESULTS

We identified 82 articles from over 50 LMICs who had studied externalising behaviour in children. Twenty-seven tools were identified, with a predominance of studies using tools from the USA and Europe. Most studies did not describe an adaptation and evaluation process, with only one study following recommended criteria. New tools were identified which both screen and assess externalising behaviour which have not yet been utilised across settings.

CONCLUSIONS

Although tools from the USA and Europe are often utilised to screen and assess for externalising behaviour problems in children in LMICs, the conceptual frameworks behind the use of these tools in other cultural contexts are not always carefully examined. In order to have valid data across cultures, we should aim to adapt and validate tools before use. Provision of processes to validate tools across LMIC settings would be beneficial.

Neurodevelopmental disorders in children aged 2-9 years: Population-based burden estimates across five regions in India

BACKGROUND

Neurodevelopmental disorders (NDDs) compromise the development and attainment of full social and economic potential at individual, family, community, and country levels. Paucity of data on NDDs slows down policy and programmatic action in most developing countries despite perceived high burden.

METHODS AND FINDINGS

We assessed 3,964 children (with almost equal number of boys and girls distributed in 2-<6 and 6-9 year age categories) identified from five geographically diverse populations in India using cluster sampling technique (probability proportionate to population size). These were from the North-Central, i.e., Palwal (N = 998; all rural, 16.4% non-Hindu, 25.3% from scheduled caste/tribe [SC-ST] [these are considered underserved communities who are eligible for affirmative action]); North, i.e., Kangra (N = 997; 91.6% rural, 3.7% non-Hindu, 25.3% SC-ST); East, i.e., Dhenkanal (N = 981; 89.8% rural, 1.2% non-Hindu, 38.0% SC-ST); South, i.e., Hyderabad (N = 495; all urban, 25.7% non-Hindu, 27.3% SC-ST) and West, i.e., North Goa (N = 493; 68.0% rural, 11.4% non-Hindu, 18.5% SC-ST). All children were assessed for vision impairment (VI), epilepsy (Epi), neuromotor impairments including cerebral palsy (NMI-CP), hearing impairment (HI), speech and language disorders, autism spectrum disorders (ASDs), and intellectual disability (ID). Furthermore, 6-9-year-old children were also assessed for attention deficit hyperactivity disorder (ADHD) and learning disorders (LDs). We standardized sample characteristics as per Census of India 2011 to arrive at district level and all-sites-pooled estimates. Site-specific prevalence of any of seven NDDs in 2-<6 year olds ranged from 2.9% (95% CI 1.6-5.5) to 18.7% (95% CI 14.7-23.6), and for any of nine NDDs in the 6-9-year-old children, from 6.5% (95% CI 4.6-9.1) to 18.5% (95% CI 15.3-22.3). Two or more NDDs were present in 0.4% (95% CI 0.1-1.7) to 4.3% (95% CI 2.2-8.2) in the younger age category and 0.7% (95% CI 0.2-2.0) to 5.3% (95% CI 3.3-8.2) in the older age category. All-site-pooled estimates for NDDs were 9.2% (95% CI 7.5-11.2) and 13.6% (95% CI 11.3-16.2) in children of 2-<6 and 6-9 year age categories, respectively, without significant difference according to gender, rural/urban residence, or religion; almost one-fifth of these children had more than one NDD. The pooled estimates for prevalence increased by up to three percentage points when these were adjusted for national rates of stunting or low birth weight (LBW). HI, ID, speech and language disorders, Epi, and LDs were the common NDDs across sites. Upon risk modelling, noninstitutional delivery, history of perinatal asphyxia, neonatal illness, postnatal neurological/brain infections, stunting, LBW/prematurity, and older age category (6-9 year) were significantly associated with NDDs. The study sample was underrepresentative of stunting and LBW and had a 15.6% refusal. These factors could be contributing to underestimation of the true NDD burden in our population.

CONCLUSIONS

The study identifies NDDs in children aged 2-9 years as a significant public health burden for India. HI was higher than and ASD prevalence comparable to the published global literature. Most risk factors of NDDs were modifiable and amenable to public health interventions.

ADHD research in India: A narrative review

INTRODUCTION

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder with no clear etiopathogenesis. Owing to unique socio cultural milieu of India, it is worthwhile reviewing research on ADHD from India and comparing findings with global research. Thereby, we attempted to provide a comprehensive overview of research on ADHD from India.

METHODS

A boolean search of articles published in English from September 1966 to January 2017 on electronic search engines Google Scholar, PubMed, IndMED, MedIND, using the search terms "ADHD", "Attention Deficit and Hyperactivity Disorder", "Hyperactivity" ,"Child psychiatry", "Hyperkinetic disorder", "Attention Deficit Disorder", "India"was carried out and peer - reviewed studies conducted among human subjects in India were included for review. Case reports, animal studies, previous reviews were excluded from the current review.

RESULTS

Results of 73 studies found eligible for the review were organized into broad themes such as epidemiology, etiology, course and follow up, clinical profile and comorbidity, assessment /biomarkers, intervention/treatment parameters, pathways to care and knowledge and attitude towards ADHD.

DISCUSSION

There was a gap noted in research from India in the domains of biomarkers, course and follow up and non-pharmacological intervention. The prevalence of ADHD as well as comorbidity of Bipolar Disorder was comparatively lower compared to western studies. The studies found unique to India include comparing the effect of allopathic intervention with Ayurvedic intervention, yoga as a non pharmacological intervention. There is a need for studies from India on biomarkers, studies with prospective research design, larger sample size and with matched controls.

Consensus Statement of the Indian Academy of Pediatrics on Evaluation and Management of Attention Deficit Hyperactivity Disorder

JUSTIFICATION

Attention-Deficit/Hyperactivity Disorder (ADHD) is highly prevalent in children worldwide. Management of ADHD requires a systematic, multidisciplinary approach and therefore evidence-based, standardized national guidelines are essential.

PROCESS

A meeting for formulation of national consensus guidelines on neurodevelopmental disorders was organized by Indian Academy of Pediatrics in Mumbai, on 18th and 19th December, 2015. The invited experts included Pediatricians, Developmental Pediatricians, Pediatric Neurologists, Psychiatrists, Remedial Educators and Clinical Psychologists. The participants framed guidelines after extensive discussions.

OBJECTIVE

To provide consensus guidelines on evaluation and management of ADHD in children in India.

RECOMMENDATIONS

ADHD is a chronic condition and thus education of patients, families, and teachers regarding the diagnosis is an integral part of management. Involvement of patient the and the family in the management program is extremely vital. Management of ADHD centers on the achievement of target outcomes, which are chosen in collaboration with the child, parents, and school personnel. Coexisting conditions must be treated concurrently with ADHD. Modalities of management of ADHD include behavioral interventions, medications, and educational interventions. These modalities can be implemented individually or in combination.

CDC Kerala--The Untold Story

This article is our life time experience in conceptualizing and systematically developing Child Development Centre (CDC) Kerala in the last 25 years, from a research project to a national training centre in child and adolescent development and premarital counseling. CDC Kerala's major contribution was in creating a 'conceptual framework' of a valid link between childhood disability, low birth weight, adolescent girls' nutrition and fetal onset adult lifestyle diseases. It all started with a randomized controlled trial (RCT) proving beyond doubt that early stimulation is effective in improving the neurodevelopmental status of high risk babies at one and two years and the same cohort was followed-up in detail at 5, 13, 16, 19 and 24 completed years. The process of establishing CDC Kerala is being presented under (i) clinical child development, (ii) adolescent care counseling, (iii) young adults and premarital counseling and (iv) institution building.

INCLEN Diagnostic Tool for Neuromotor Impairments (INDT-NMI) for primary care physician: development and validation

OBJECTIVE

To develop and validate a diagnostic tool for use by primary care physicians for diagnosing neuro-motor impairment among 2-9 year old children in primary care settings.

STUDY DESIGN

Modified Delphi technique involving national (n=49) and international (n=6) experts was used for development of INDT-NMI. The tool was then validated through a cross sectional study.

SETTING

Neurology specialty clinics of three tertiary care pediatric centers in New Delhi, India.

PARTICIPANTS

454 children aged 2-9 years [mean (SD) age: 60.4 (23.7) mo], selected through systematic random sampling, underwent assessment for identification and classification of neuromotor impairments (NMI).

INTERVENTION

All study subjects were first administered INDT-NMI (candidate test) by a trained physician followed by expert assessment for NMI and other neurodevelopment disorders (NDD) by team of two pediatric neurologists (Gold standard).

RESULTS

According to expert evaluation, 171 (37.8%) children had neuromotor impairments. There were four categories of subjects: NMI alone (n=66); NMI+other NDDs (n=105); Other NDDs without NMI (n=225) and 'Normal' group (n=58). Using expert evaluation as gold standard, overall sensitivity of the INDT-NMI was 75.4% and specificity was 86.8%. INDT-NMI helped graduate physicians to correctly classify 86.6% (112/129) children with NMI into different types (cerebral palsy, neuromotor diseases and other NMI). Graduate physicians assigned 40 children (8.8%) as 'indeterminate', 38 (95%) of whom had either NDD and/or NMI and thus merited referral. Misclassification of NMI occurred in those with mild changes in muscle tone, dystonia, or ataxia and associated NDDs.

CONCLUSIONS

Graduate primary care physicians with a structured short training can administer the new tool and diagnose NMI in 2-9 year old children with high validity. INDT-NMI requires further evaluation in actual primary care settings.
