Insights

Researchers identified early biomarkers for autism spectrum disorder (ASD) in infants with tuberous sclerosis complex (TSC). This collaborative study also examined seizures, development, and epilepsy in young children with TSC.

Area of Science:

  • Neuroscience
  • Developmental Pediatrics
  • Genetics

Background:

  • Tuberous Sclerosis Complex (TSC) is a genetic disorder associated with increased risk of neurodevelopmental conditions, including autism spectrum disorder (ASD).
  • Early identification of biomarkers for ASD in infants with TSC is crucial for timely intervention.
  • Longitudinal research is needed to understand the complex interplay of neurological, developmental, and behavioral factors in TSC.

Purpose of the Study:

  • To identify early biomarkers for autism spectrum disorder (ASD) in infants with tuberous sclerosis complex (TSC).
  • To investigate the relationship between seizures and early development in infants and young children with TSC.
  • To explore early biomarkers for epilepsy and developmental delay in this population.

Main Methods:

  • A 6-site collaborative network (TACERN) conducted longitudinal research.
  • Multidisciplinary teams (psychology, neurology, pediatrics, genetics, speech-language pathology) assessed neurological status, brain structure/function, and neurodevelopmental phenotype.
  • Data collection focused on behavioral challenges, seizures, and developmental trajectories.

Main Results:

  • Identification and measurement of early symptoms indicative of ASD in infants with TSC.
  • Established correlations between seizure activity and early developmental outcomes.
  • Identified potential early biomarkers for epilepsy and developmental delay in young children with TSC.

Conclusions:

  • The TACERN network successfully facilitated collaborative research on TSC and ASD.
  • Key insights were gained into early ASD symptoms, seizure-development relationships, and biomarkers for epilepsy/delay in TSC.
  • Lessons learned from this multisite collaboration inform future research and clinical training for TSC-related neurodevelopmental disorders.

Impact of Groups on Groups

Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

Impact01:30

Impact

Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Sustainable Development

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Impact Loading01:19

Impact Loading

Impact loading occurs when a moving object collides with a stationary structure, such as a rod with a uniform cross-sectional area fixed at one end. Under these conditions, the rod absorbs the kinetic energy from the striking object, leading to deformation and subsequent stress development. As the rod returns to its original position and reaches maximum stress, the absorbed energy, initially manifested as kinetic energy, transforms entirely into strain energy.
In cases of elastic deformation,...
