Summary
Children with delayed visual evoked potential (VEP) results showed more developmental delays. VEP can indicate visual impairment and serve as an early sign for ophthalmologist consultation in children with developmental concerns.
Area of Science:
- Neuroscience
- Developmental Pediatrics
- Ophthalmology
Background:
- Developmental disorders in young children require accurate assessment.
- Visual evoked potential (VEP) is a tool to assess visual pathway function.
- Early identification of visual impairment is crucial for neurodevelopmental outcomes.
Purpose of the Study:
- To investigate neurodevelopmental outcomes in children with developmental disorders based on VEP results.
- To determine if VEP latency can predict developmental delays.
Main Methods:
- Retrospective analysis of 322 children under 42 months with developmental disability.
- Comparison of Bayley Scales of Infant and Toddler Development (BSID-II) scores between children with normal and delayed VEP latency.
- Mann-Whitney U-test used for statistical analysis.
Main Results:
- Children with delayed VEP latency exhibited significantly lower BSID-II index scores and developmental quotients.
- This difference was particularly pronounced in younger children (under 23 months).
- No significant differences in baseline characteristics were observed between groups.
Conclusions:
- Delayed VEP latency is associated with greater developmental delay in young children.
- VEP is a valuable, easily applicable tool for assessing children with suspected developmental delay and potential visual impairment.
- VEP results can prompt early ophthalmological consultation.

Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

01:27Introduction to Developmental Psychology
1.7K
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...

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,...
