Autism spectrum disorders (ASD) represent a group of neurodevelopmental conditions characterized by challenges in social communication and restricted, repetitive behaviours. ASD affects children worldwide and contributes substantially to non‑fatal health burden, particularly in childhood and adolescence, underscoring the need for early identification and inclusive support systems [1]. Despite growing global awareness, access to diagnostic services and evidence‑based care remains uneven across regions, with many low‑ and middle‑income countries lacking structured screening programs and trained professionals [2]. These disparities position autism not only as a clinical concern but as an urgent global health and equity issue that demands advocacy, research, and policy change.

Recent systematic reviews estimate global prevalence of autism in children at approximately 0.77%, although rates vary substantially by region and methodology [3]. This variation reflects differences in health system capacity, socio‑cultural recognition of neurodevelopmental conditions, and access to diagnostic services. In many contexts, caregivers and providers lack awareness of early signs, leading to delays in identification until well beyond critical developmental periods. Stigma around neurodevelopmental differences further limits help‑seeking behaviour and engagement with health systems.

Timely diagnosis is essential, as early intervention has been linked to improvements in communication skills, functional abilities, and long‑term outcomes for autistic individuals [3]. However, global inequities persist: families in low‑resource settings are far less likely to access early detection services compared with those in high‑income countries, and interventions may be unavailable, unaffordable, or culturally inappropriate. Innovative approaches, including telehealth assessment strategies and machine learning–assisted screening tools, show promise for expanding diagnostic reach where specialist availability is limited [4]. Coupling technological innovation with community‑based health worker training could accelerate early recognition and referral pathways in underserved regions.

Inclusive care must extend beyond timely diagnosis to embrace person‑centred, neurodiversity‑affirming practices. Health systems should move away from deficit‑centred models toward approaches that honour individual strengths, support meaningful participation in education and community life, and involve autistic individuals and their families in shared decision‑making. Inclusive care also requires ongoing professional education, culturally sensitive communication, and public health campaigns that challenge stigma and misinformation.

Medical students and future healthcare professionals have a unique role to play in advancing these goals. As emerging clinicians and health advocates, students can champion ASD education within medical curricula, including developmental surveillance and culturally informed care. Engagement in community outreach, research, and public awareness initiatives allows students to bridge evidence and practice, promote early detection, and support family‑centred services. Collaborating with non‑governmental organizations and community leaders enhances culturally adapted models of support that respond to local needs.

Policy advocacy is equally important. Students can contribute to national and global dialogues advocating for autism to be integrated into universal health coverage and mental health frameworks. Investments in workforce capacity building, interdisciplinary care teams, and comprehensive data systems are necessary to ensure services are equitable and rights‑based.

By embracing advocacy, education, and innovation now, medical students can help shape health systems that are more inclusive, equitable, and responsive to autistic individuals worldwide.
