Attention-deficit/hyperactivity disorder (ADHD) is one of the most commonly diagnosed pediatric neurobehavioral disorders, but it is known that sensory impairments in children are associated with a higher percentage of this disorder. On one hand, for this children is more difficult to focus while reading or listening to lectures in a classroom; on the other hand, ADHD is diagnosed based on tests that consider school performance and attentiveness (among others factors). So, these children could be misdiagnosed.

Given that children with vision impairment may be more likely to be diagnosed with ADHD than other children, to improve their visual acuity can lead to the change of diagnostic in some of them. It has been suggested that, in the United States, there is a significant possibility that almost 1 million children entering kindergarten diagnosed with ADHD did not have the disorder.

Dietary supplementation with omega-3 polyunsaturated fatty acids improves visual acuity (the ability to distinguish details and shapes of objects, e.g.: letters and numbers at a given distance) in school-age children with lower IQs or ADHD.
