A descriptive cross-sectional study was undertaken with Sinhala speaking students from grades 1 and 2 in the Gampaha District of Sri Lanka to determine how akshara graphical features influence emerging reading skills. A battery of locally validated assessments evaluated akshara knowledge (recognition and production), word reading (accurate and fluent), accurate sentence reading and visual perceptual skills. The study examined the graphic complexity of akshara by examining the number of disconnected components (DC), connected points (CP) and simple features (SF).

Most children with autism spectrum disorder live in low- and middle-income countries. Most of them do not have access to timely and culturally acceptable interventions. Research from high-income countries and low- and middle-income countries, such as Sri Lanka, show that parent-mediated intervention programmes improve functional outcomes, highlighting the importance of parents as partners.

Majority of under-five children with developmental disabilities live in low- and middle-income countries (LMIC). A considerable proportion of disabilities results from perinatal adversities. The neonatal and infant mortality rates in India, Bangladesh, and Sri Lanka have improved over the last two decades, implying survival of infants at risk for developmental impairments.

Introduction: Time-critical neonatal trials in low-and-middle-income countries (LMICs) raise several ethical issues. Using a qualitative-dominant mixed-methods design, we explored informed consent process in Hypothermia for encephalopathy in low and middle-income countries (HELIX) trial conducted in India, Sri Lanka and Bangladesh.

Methods: Term infants with neonatal encephalopathy, aged less than 6 hours, were randomly allocated to cooling therapy or usual care, following informed parental consent.

Objective: To assess the developmental progression and compare the developmental attainments of children treated with two hormonal therapies for infantile spasms (IS) over two years (seizure and EEG outcomes of this RCT published previously).

Methods: Newly diagnosed infants with IS were randomised to receive adrenocorticotrophin (ACTH) or prednisolone for 14 days. All underwent Bayley III Infant and Toddler Assessments in cognitive (Cog), receptive (RC) and expressive (EC) communication, fine (FM) and gross (GM) motor developmental subsets at baseline (T0), one-year (T1) and two-years (T2).

Introduction: Cerebral palsy (CP) describes a heterogeneous group of motor disorders resulting from disturbance in the developing brain. CP occurs in approximately 2.1 per 1000 live births in high-income countries, but in low- and middle-income countries (LMICs) the prevalence and severity of CP may be greater and aetiological risk factors different.
