Bad driving may have genetic basis, UCI study finds
Date:10/28/2009

Irvine, Calif., Oct. 28, 2009 Bad drivers may in part have their genes to blame, suggests a new study by UC Irvine neuroscientists.

People with a particular gene variant performed more than 20 percent worse on a driving test than people without it and a follow-up test a few days later yielded similar results. About 30 percent of Americans have the variant.

"These people make more errors from the get-go, and they forget more of what they learned after time away," said Dr. Steven Cramer, neurology associate professor and senior author of the study published recently in the journal Cerebral Cortex.

This gene variant limits the availability of a protein called brain-derived neurotrophic factor during activity. BDNF keeps memory strong by supporting communication among brain cells and keeping them functioning optimally. When a person is engaged in a particular task, BDNF is secreted in the brain area connected with that activity to help the body respond.

Previous studies have shown that in people with the variant, a smaller portion of the brain is stimulated when doing a task than in those with a normal BDNF gene. People with the variant also don't recover as well after a stroke. Given these differences, the UCI scientists wondered: Could the variant affect an activity such as driving?

"We wanted to study motor behavior, something more complex than finger-tapping," said Stephanie McHughen, graduate student and lead author of the study. "Driving seemed like a good choice because it has a learning curve and it's something most people know how to do."

The driving test was taken by 29 people 22 without the gene variant and seven with it. They were asked to drive 15 laps on a simulator that required them to learn the nuances of a track programmed to have difficult curves and turns. Researchers recorded how well they stayed on the course over time. Four days later, the test was repeated.
