According to Discovery Fit & Health, an inner ear dysfunction in children could cause neurological changes that lead to behavioral abnormalities related to attention deficit hyperactivity disorder (ADHD). Therefore, adolescents who suffer from inner ear problems could be at risk of developing ADHD, according to a recent study.

ADHD Linked to Inner Ear ProblemsFindings published online in the journal Science reveal that children and adolescents with severe inner ear problems could develop behavioral problems, such as hyperactivity. When a Ph.D. student at Albert Einstein College of Medicine noticed that some mice in a laboratory were continuously chasing their own tails, researchers — including Dr. Jean Herbert, a neuroscience and genetics professor at the college — decided to examine if poor hearing and restlessness were caused by a faulty gene in animals and humans,reports the Daily Mail. Inner ear problems typically derive from genetic defects, though they can also stem from infection or injury.

The scientists took healthy mice and deleted the gene associated with poor hearing from either the inner ear, various parts of the brain that control movement, or the entire central nervous system (CNS). Patients of severe inner ear problems have a mutation of the gene Slc12a2, which mediates the transport of sodium, potassium, and chloride molecules in various tissues, including those in the inner ear and CNS, according to the Albert Einstein College of Medicine of Yeshiva University.
