Metabolic Dysfunction Underlying Autism Spectrum Disorder and Potential Treatment Approaches

Area of Science:

• Neuroscience
• Metabolic Disorders
• Developmental Disorders

Background:

• Autism spectrum disorder (ASD) presents with core deficits in social communication and restricted behaviors, with unknown etiology.
• Current ASD treatments manage comorbidities but do not address core symptoms.
• Emerging evidence links mitochondrial dysfunction to ASD's diverse clinical manifestations.

Purpose of the Study:

• To review the evidence supporting metabolism-based therapies, specifically the ketogenic diet (KD), for treating ASD.
• To explore the role of mitochondrial function in ASD pathogenesis and therapeutic potential.
• To discuss emerging models of comorbid epilepsy and autism.

Main Methods:

• Review of existing scientific literature on ASD, mitochondrial dysfunction, and ketogenic diet therapy.
• Analysis of studies investigating ketogenic diet's effects on mitochondrial function and molecular targets.
• Examination of comorbid models linking epilepsy and autism.

Main Results:

• Mitochondrial dysfunction is implicated as a potential common pathway in ASD.
• The ketogenic diet (KD) enhances mitochondrial function and impacts molecular targets relevant to ASD.
• KD has a long-standing efficacy in treating intractable epilepsy, a common comorbidity in ASD.

Conclusions:

• Metabolism-based therapies, particularly the ketogenic diet (KD), offer a promising avenue for addressing core ASD symptoms and comorbidities.
• Further research is warranted to validate KD as an ASD treatment and identify novel therapeutic targets.
• Understanding mitochondrial mechanisms in ASD is crucial for developing effective interventions.
