Attention-deficithyperactivity disorder (ADHD) is one of the most common, yet often unrecognised, neurodevelopmental disorders worldwide, significantly affecting individuals throughout their lives. While extensive research from high-income countries has deepened our understanding of ADHD’s neurobiological foundations and psychosocial effects, awareness and recognition in low- and middle-income countries, like India, remain limited, particularly regarding policy and disability frameworks. Globally, ADHD impacts approximately 5.6%–7.6% of children and about 2.5% of adults. Symptoms typically begin in early childhood and can persist into adolescence and adulthood for many individuals.1–3
In India, (ADHD) is not officially recognised under the rights of persons with disabilities (RPwD) Act of 2016, despite the significant clinical burden it presents. This lack of recognition creates systemic gaps in access to diagnosis, treatment, accommodations, and support services. Moreover, the prevailing unawareness among educators, health professionals, and policymakers leads to delays in identification and missed opportunities for timely intervention.
Longitudinal neuroimaging studies indicate that children with ADHD exhibit atypical brain network development during critical developmental years. In comparison to their typically developing peers, these children show disrupted functional and structural connectivity in brain regions essential for attention, sensory processing, and executive control, particularly within the parietal, temporal, and frontal cortices. These changes reflect both decreased neural efficiency and compensatory reorganization of the networks. Importantly, the developmental trajectories of these brain circuits differ from typical patterns, suggesting that ADHD is a disorder related to network maturation rather than a simple dysfunction. 4
The condition frequently occurs alongside notable comorbidities, including learning challenges, oppositional defiant disorder, childhood conduct disorder, as well as anxiety, depression, and substance use, particularly during adolescence and adulthood. These associated issues hinder functioning in academic, work, and social areas, and if left untreated, can lead to lasting adverse outcomes, such as dropping out of school, encountering legal issues, and struggling with job adjustment.
From a public health perspective, the lack of recognition for ADHD within India’s disability frameworks leads to significant missed opportunities. Official acknowledgement would enable access to accommodations through inclusive education policies, workplace modifications, and legal protections. It would also promote early screening, organised teacher training, the development of clinical pathways, and the incorporation of ADHD services into primary mental health care. The disability infrastructure in India, as guided by the RPwD Act, needs to evolve to include an improved understanding of hidden disabilities.
Many countries, including the UK, Canada, Australia, and the United States, have included ADHD in their education and disability benefit systems. Their experiences demonstrate that evidence-based accommodations, when supported by inclusive policies, can significantly improve quality of life and reduce long-term costs for society.5–8
As India aspires to meet its sustainable development goals and implement NEP 2020 effectively, prioritising neurodevelopmental conditions like ADHD is imperative. Recognising ADHD under the RPwD Act will be a vital step toward equitable access, reduced stigma, and long-overdue support for millions of children and adults in need.
