Insights

Children with sickle cell disease (SCD) show declining cognitive function by 24 months. Early interventions are crucial to support neurocognitive development in these young children.

Area of Science:

  • Pediatric Neurology
  • Developmental Psychology
  • Hematology

Background:

  • Sickle cell disease (SCD) affects neurocognitive development in young children.
  • Understanding risk factors is crucial for early intervention.

Purpose of the Study:

  • To assess neurocognitive development in children with SCD from 6 to 36 months.
  • To examine contributions of biomedical and parenting risks to child functioning.
  • To investigate factors influencing parent adjustment.

Main Methods:

  • Longitudinal study of 89 African American children with SCD and their parents.
  • Neurocognitive and psychomotor development assessed at 6, 12, 24, and 36 months.
  • Parental cognitive processes, adjustment, and family functioning measured via self-report.

Main Results:

  • Cognitive functioning (MDI) declined significantly between 12 and 24 months.
  • Poorer cognitive function linked to learned-helplessness attributional style and HbSS phenotype.
  • Parental adjustment issues associated with daily stress, lack of knowledge, low efficacy, and HbSC phenotype.

Conclusions:

  • Young children with SCD are at risk for neurocognitive impairment.
  • Findings support early intervention programs to enhance neurocognitive development.

Three Developmental Domains01:29

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

Motor Skills Development During Early Childhood

Early childhood is a period of rapid motor development in which children refine gross and fine motor skills. These abilities increase independence and support social interaction, play, and learning.Gross Motor SkillsGross motor skills involve coordinated movements of large muscle groups, including running, jumping, and climbing. By about 2.5 years, most children can jump with both feet. Hopping, which requires greater balance and strength, usually emerges around age 4.Stair climbing also...

Domains of Human Development

Developmental scientists study human growth across three major domains: physical, cognitive, and psychosocial development. Although each domain describes a different aspect of development, they are closely connected. Changes in one domain can affect functioning in the other two, so human development reflects several interacting processes.Physical DevelopmentThe physical domain includes changes in the body and brain, sensory abilities, motor skills, and overall health. Physical conditions can...
Cognitive Neuroscience Approach01:21

Cognitive Neuroscience Approach

The cognitive neuroscience approach to development focuses on how the central nervous system supports emerging cognitive abilities. Neuroimaging and behavioral studies link specific neural systems to memory and cognitive processing in infancy.Distinct Memory Systems in the Developing BrainInfant long-term memory includes two distinct systems: implicit and explicit memory. Implicit, or nondeclarative, memory involves unconscious recall of skills and routines. It develops early and appears in...
Information Processing Approach01:30

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is also...
Vision During Infancy and Toddlerhood01:23

Vision During Infancy and Toddlerhood

At birth, vision is the least developed of the major senses because the visual system is still structurally and neurologically immature. The retinas, optic nerves, and visual regions of the brain continue to mature after birth. As a result, newborns have limited visual acuity, or sharpness and clarity of vision, and respond best to objects viewed at close range, roughly 8 to 12 inches away.Rapid Visual DevelopmentVision improves rapidly during the first few months as infants observe and...
