Summary
Children with dyslexia exhibit impaired executive functions, including inattention and impulsivity. Cortexin treatment showed slightly better results than encephabol in improving reading skills and cognitive functions.
Area of Science:
- Neuroscience
- Developmental Psychology
- Pediatrics
Background:
- Children with dyslexia often present with executive function deficits.
- Understanding these deficits is crucial for effective intervention.
Purpose of the Study:
- To investigate executive function disorders in children with dyslexia.
- To evaluate the efficacy of Cortexin in treating these deficits.
Main Methods:
- 60 children with dyslexia (ages 8-11) and 60 controls were assessed.
- Executive functions were evaluated using neurological exams, EEG, and cognitive tests (working memory, attention, impulsivity).
- Dyslexia group received Cortexin or Encephabol; outcomes were compared after one month.
Main Results:
- Children with dyslexia showed higher inattention/impulsivity and lower working memory than controls.
- Both treatments improved reading skills, attention, and working memory.
- Cortexin demonstrated slightly superior efficacy (73.3% improvement) compared to Encephabol (60.0%).
Conclusions:
- Executive function impairments are evident in children with dyslexia.
- Cortexin treatment led to significant neurophysiological changes, suggesting enhanced brain regulatory system activation.
- Cortexin appears to be a promising therapeutic agent for dyslexia-associated executive function deficits.

01:25Learning Disabilities
376
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.

01:30Information Processing Approach
286
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...

01:27Language and Cognition
545
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

01:30Attention-Deficit/Hyperactivity Disorder
535
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms

01:30Oppositional Defiant Disorder
285
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

01:24Working Memory
543
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...
