A working memory intervention for children with prenatal alcohol exposure: Pilot study

Area of Science:

• Neuroscience
• Developmental Psychology
• Cognitive Rehabilitation

Background:

• Prenatal alcohol exposure (PAE) can negatively impact cognitive functions, particularly working memory and attention.
• Computerized cognitive training programs offer a potential avenue for intervention in affected children.
• Working memory and attention are crucial for academic success and daily functioning.

Purpose of the Study:

• To evaluate the short- and long-term effects of the Cogmed© working memory training program.
• To assess the impact of the intervention on children with PAE and typically developing children.
• To determine if cognitive improvements are maintained over time.

Main Methods:

• A 25-session Cogmed© intervention was administered to 38 children (ages 4-13).
• Participants were divided into two groups: PAE (n=20) and typically developing (n=18).
• Cognitive assessments were conducted immediately after the intervention and at a five-week follow-up.

Main Results:

• Both PAE and typically developing groups showed significant improvements in working memory and attentional control post-intervention.
• These cognitive gains were partially retained at the five-week follow-up assessment.
• Preliminary evidence suggests sustained benefits of computerized interventions for attention and working memory.

Conclusions:

• Computerized working memory training may be an effective intervention for improving cognitive functions in children.
• The positive effects of Cogmed© on working memory and attention appear to have some long-term durability.
• Further research is warranted to explore the broader applicability and long-term efficacy of such interventions.
