Got ADD? Blame Your Ears
New study suggests that behavioral problems could be due to disorders in the ear.
According to a new study in Science magazine, ear disorders could be the cause of behavioral disorders.
This is kind of a big deal. Traditionally, behavioral problems such as ADHD and ADD are thought to be tied to brain activity, though many scientist have often noted that children with inner-ear issues often have behavioral problems as well.
Albert Einstein College of Medicine of Yeshiva University in New York conducted the study on mice, discovering, amongst many findings, that when they blocked the activity of the Slc12a2 gene in the inner ear (a gene also found in humans), this caused relatively normal mice to become increasingly active.
The study raises the question of how sensory impairment could potentially cause molecular changes in the brain, leading to behavior disorders that are universally believed to originate solely in the brain.
