Yes. ADHD underdiagnosis in developing countries is significantly more widespread compared to high-income regions. While ADHD affects people globally at similar rates, the ability to recognise, diagnose, and treat it is heavily influenced by a country’s healthcare infrastructure, funding, and public understanding of mental health. 

In many low-income nations, ADHD remains under-recognised both by the public and within medical communities. Mental health is often deprioritised, and awareness gaps about neurodevelopmental conditions like ADHD persist. Without adequate training or resources, professionals may not have the tools to identify symptoms and families may not have the means or confidence to seek help.

Why ADHD Is Missed in Low-Income Countries 

Several factors contribute to ADHD underdiagnosis in developing countries: 

Limited healthcare infrastructure  

Mental health services are often under-resourced or absent altogether, especially outside urban centres. 

Lack of specialist training  

General practitioners may not be trained to spot ADHD, especially in adults or in less overt cases. 

Cultural and social barriers  

In some societies, ADHD-related behaviours are misunderstood or stigmatised, discouraging open discussion or medical inquiry. 

In conclusion, the result is that millions of people particularly children go without diagnosis or treatment, limiting their educational and life potential. Improving ADHD awareness and access in developing countries is essential for global mental health equity.
