Is there a link between childhood obesity and ADHD, learning disabilities?
Date:2/19/2013

URBANA A University of Illinois study has established a possible link between high-fat diets and such childhood brain-based conditions as attention deficit hyperactivity disorder (ADHD) and memory-dependent learning disabilities.

"We found that a high-fat diet rapidly affected dopamine metabolism in the brains of juvenile mice, triggering anxious behaviors and learning deficiencies. Interestingly, when methylphenidate (Ritalin) was administered, the learning and memory problems went away," said Gregory Freund, a professor in the U of I College of Medicine and a member of the university's Division of Nutritional Sciences.

The research was published in Psychoneuroendocrinology and is available pre-publication online at http://dx.doi.org/10.1016/j.psyneuen.2013.01.004.

Freund said that altered dopamine signaling in the brain is common to both ADHD and the overweight or obese state. "And an increase in the number of dopamine metabolites is associated with anxiety behaviors in children," he added.

Intrigued by the recent upsurge in both child obesity and adverse childhood psychological conditions, including impulsivity, depression, and ADHD, Freund's team examined the short-term effects of a high-fat (60% calories from fat) versus a low-fat (10% calories from fat) diet on the behavior of two groups of four-week-old mice. A typical Western diet contains from 35 to 45 percent fat, he said.

"After only one week of the high-fat diet, even before we were able to see any weight gain, the behavior of the mice in the first group began to change," he said.

Evidence of anxiety included increased burrowing and wheel running as well a reluctance to explore open spaces. The mice also developed learning and memory deficits, including decreased ability to negotiate a maze and impaired object recognition.
