Insights

Cognitive postconcussive symptoms (PCS) are more persistent than somatic PCS in children up to two weeks after injury. Early interventions targeting cognitive symptoms may help manage persistent PCS in young athletes.

Area of Science:

  • Pediatric Sports Medicine
  • Neuroscience
  • Clinical Psychology

Background:

  • Postconcussive symptoms (PCS) are common after mild traumatic brain injury in children.
  • Tracking symptom evolution is crucial for effective management and recovery.
  • The Child Sports Concussion Assessment Tool 3 (Child SCAT) is used to evaluate concussion symptoms.

Purpose of the Study:

  • To investigate somatic and cognitive PCS using the Child SCAT symptom evaluation subtest (cSCAT3-SE).
  • To track PCS in children aged 5-12 years up to 2 weeks post-injury.
  • To compare the time course of somatic versus cognitive PCS.

Main Methods:

  • 96 participants (aged 5-12 years) completed assessments at 48 hours, 2-4 days, and 2 weeks post-injury.
  • The Wilcoxon signed-rank test analyzed differences between cognitive and somatic symptoms over time.
  • The Friedman test analyzed differences within symptom types over time.

Main Results:

  • Cognitive PCS were significantly higher than somatic PCS at all time points.
  • Cognitive PCS significantly declined from 4 days onwards post-injury.
  • Somatic PCS significantly declined as early as 48 hours post-injury.

Conclusions:

  • Cognitive PCS are more persistent than somatic PCS in children up to 2 weeks post-injury.
  • Differences in symptom presentation emerge within days of injury.
  • Symptom-specific interventions may benefit children with persistent PCS.

Traumatic Memory01:20

Traumatic Memory

Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

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...

Role of Cerebellum and Prefrontal Cortex in Memory

The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...
