Executive functioning and working memory in fetal alcohol spectrum disorder

Area of Science:

• Neuroscience
• Developmental Psychology
• Pediatrics

Background:

• Fetal Alcohol Spectrum Disorders (FASD) are associated with prenatal alcohol exposure.
• Executive functioning (EF) and working memory are crucial cognitive domains.
• Deficits in these areas are frequently observed in individuals with FASD.

Purpose of the Study:

• To critically review existing research on executive functioning (EF) and working memory in individuals with FASD.
• To identify patterns and inconsistencies in the current literature.
• To highlight areas for future research and clinical implications.

Main Methods:

• Systematic literature review of studies investigating EF and working memory in FASD.
• Analysis of research findings concerning cognitive flexibility, planning, inhibition, and fluency.
• Examination of studies linking prenatal alcohol exposure to neurodevelopmental changes.

Main Results:

• Individuals with FASD consistently demonstrate deficits across various EF domains, including cognitive flexibility, planning, inhibition, and fluency.
• Working memory impairments are a common finding in FASD.
• These EF deficits are observed independently of facial dysmorphology and are not solely attributable to lower IQ.

Conclusions:

• Prenatal alcohol exposure significantly impacts the development of executive functions and working memory.
• Further research with larger sample sizes and standardized measures is needed to clarify inconsistencies.
• Understanding the specific EF profile in FASD is crucial for improved diagnosis and targeted interventions.
