Diminished culpability in fetal alcohol spectrum disorders (FASD)

Area of Science:

• Neuroscience
• Forensic Psychology
• Developmental Psychology

Background:

• Fetal Alcohol Spectrum Disorders (FASD) are neurodevelopmental conditions resulting from prenatal alcohol exposure.
• Cognitive impairments, particularly in executive functioning, are characteristic of FASD, stemming from structural brain damage.
• Impaired executive functioning, including reasoning and impulse control, has legal implications for criminal responsibility, analogous to intellectual disability.

Purpose of the Study:

• To explore the biological basis for diminished criminal responsibility in individuals with FASD.
• To draw parallels between the legal culpability of individuals with FASD and those with intellectual disability.
• To argue for reduced criminal responsibility in FASD cases due to impaired executive functioning.

Main Methods:

• Review of existing literature on FASD, brain structure, executive functions, and legal culpability.
• Comparative analysis of cognitive deficits in FASD and intellectual disability.
• Application of legal principles, including mens rea and the rationale from the Atkins Supreme Court decision.

Main Results:

• FASD involves structural brain damage leading to functional limitations in cognition, especially executive functioning.
• Impaired executive functioning, affecting reasoning and impulse control, is a key factor in diminished criminal responsibility.
• The legal precedent set by the Atkins decision, which considers organic brain dysfunction, supports reduced culpability for individuals with similar FASD-related impairments.

Conclusions:

• There is a biological basis for diminished criminal responsibility in offenders with FASD.
• Impaired executive functioning in FASD directly impacts the legal concept of mens rea (guilty mind).
• Individuals with FASD exhibiting similar brain dysfunction to those with intellectual disability should have reduced criminal culpability.
