Autism spectrum disorder across the lifespan: Dynamic symptom trajectories and multidimensional support framework

Area of Science:

• Neurodevelopmental Disorders
• Lifespan Psychology
• Public Health

Background:

• Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition with core symptoms of social communication deficits and restricted, repetitive behaviors.
• While research often focuses on pediatric ASD, adult and geriatric populations have distinct needs that are less comprehensively addressed.
• Symptom presentation and challenges in ASD evolve dynamically across the lifespan.

Purpose of the Study:

• To provide an overview of ASD epidemiology and etiology.
• To examine age-dependent symptom evolution and challenges throughout the lifespan.
• To propose an individualized, stage-specific life-course support framework for ASD.

Main Methods:

• Literature review of epidemiology, etiology, and lifespan trajectories of ASD.
• Analysis of age-dependent symptom evolution and associated challenges.
• Development of a proposed life-course support framework for distinct developmental phases.

Main Results:

• ASD symptoms and challenges vary significantly across developmental stages, from childhood to advanced age.
• Current research and support predominantly focus on pediatric ASD, leaving older populations underserved.
• A comprehensive understanding of ASD across the lifespan is crucial for effective support.

Conclusions:

• A stage-specific, individualized life-course support framework is needed to address the diverse needs of individuals with ASD.
• This framework should empower functional resilience and transcend mere symptomatic management.
• Future research and practice should prioritize serving the entire autism spectrum across all life stages.
