Insights

A 2-hour electroencephalography (EEG) monitoring is highly effective for diagnosing neurological abnormalities in children with developmental disabilities, even without apparent seizures. This diagnostic yield supports its use as a screening tool for this population.

Area of Science:

  • Pediatric Neurology
  • Neurophysiology
  • Developmental Disabilities

Background:

  • Developmental disabilities often present without clear seizure activity, making diagnosis challenging.
  • Electroencephalography (EEG) is a key diagnostic tool for identifying neurological abnormalities.

Purpose of the Study:

  • To evaluate the diagnostic yield of a 2-hour awake and asleep electroencephalography (EEG) monitoring in children with developmental disabilities.
  • To determine the utility of EEG in identifying subclinical neurological abnormalities in this population.

Main Methods:

  • Retrospective analysis of children under 9 years with developmental disabilities undergoing EEG.
  • Exclusion of patients with a history of seizures or parental suspicion of seizures.
  • Standardized 2-hour awake and asleep EEG monitoring was performed on all eligible patients.

Main Results:

  • Nineteen out of 32 (59%) patients exhibited abnormal EEG findings.
  • Fifteen patients (47%) showed epileptiform discharges.
  • Four children had abnormal background activity without epileptiform discharges.

Conclusions:

  • A 2-hour awake and asleep EEG monitoring demonstrates a high diagnostic yield in children with developmental disabilities.
  • EEG screening is justifiable for children with developmental disabilities due to its ability to detect abnormalities.
  • This study supports the routine use of EEG for early detection of neurological issues in this vulnerable group.

ATP Yield01:31

ATP Yield

Cellular respiration produces 30 - 32 ATP per glucose molecule. Although most of the ATP results from oxidative phosphorylation and the electron transport chain (ETC), 4 ATP are gained beforehand (2 from glycolysis and 2 from the citric acid cycle).
The ETC is embedded in the inner mitochondrial membrane and is comprised of four main protein complexes and an ATP synthase. NADH and FADH2 pass electrons to these complexes, which pump protons into the intermembrane space. This distribution of...

Reaction Yield02:22

Reaction Yield

The theoretical yield of a reaction is the amount of product estimated to form based on the stoichiometry of the balanced chemical equation. The theoretical yield assumes the complete conversion of the limiting reactant into the desired product. The amount of product that is obtained by performing the reaction is called the actual yield, and it may be less than or (very rarely) equal to the theoretical yield.

Intellectual Disability01:29

Intellectual Disability

Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

Learning Disabilities01:25

Learning Disabilities

Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Introduction to Developmental Psychology01:27

Introduction to Developmental Psychology

Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

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,...
