Improving working memory abilities in individuals with Down syndrome: a treatment case study

Area of Science:

• Cognitive Psychology
• Neurodevelopmental Disorders
• Genetics

Background:

• Individuals with Down's syndrome (DS) exhibit significant deficits in working memory (WM) compared to typically developing peers.
• Visuo-spatial WM is generally better preserved than verbal WM in individuals with DS.

Purpose of the Study:

• To investigate the efficacy of a targeted intervention for improving short-term memory (STM) and WM abilities in adolescents with DS.
• To assess the impact of a school-based visuo-spatial WM training program on cognitive performance.

Main Methods:

• A school-based intervention program targeting visuo-spatial WM was administered to two teenage participants with DS over six weeks.
• WM abilities were assessed before and after the intervention using a battery of tasks.
• Performance was compared to age- and non-verbal mental age-matched typically developing controls.

Main Results:

• Participants demonstrated improvements in specific trained WM tasks, particularly those assessing visuo-spatial WM.
• Some improvements were also observed in non-trained WM tasks, suggesting potential generalization of skills.
• The intervention showed promise in enhancing WM abilities in the studied individuals with DS.

Conclusions:

• Targeted interventions can potentially improve working memory skills in individuals with Down's syndrome.
• The findings have significant implications for educational and clinical strategies aimed at supporting cognitive development in DS.
• Further research is warranted to explore the long-term effects and broader applicability of WM training in this population.
