Where is adhd most common in the world?
ADHD is a global phenomenon and is found in all countries and cultures around the world. However, the prevalence of ADHD can vary widely between countries and regions. According to the World Health Organization, the prevalence of ADHD ranges from around 1% to 20% among school-aged children worldwide, with an estimated global average of about 5%. However, it is important to note that these estimates are based on studies that used different diagnostic criteria and assessment methods, so the true prevalence of ADHD may be difficult to determine with precision. Additionally, ADHD is often underdiagnosed and undertreated in many parts of the world, particularly in low- and middle-income countries.
