"Don't blame me, blame my genes if I can't drive."
That is surely the implication of a study conducted by neuroscientists at the University of California, Irvine (UCI), which found the variant in seven of 29 people who performed at least 20 percent worse on the test than the other 22 people who did not have the gene variant.
The particular gene variant, which seems to be inherited, interferes with the availability of the brain-derived neurotrophic factor (BDNF), that keeps memory strong by supporting communication among the brain cells. Previous studies indicated that persons with the BDNF variant have less brain response than those without the variant while performing tasks. Additionally, those with the variant don't recover as well from a stroke.
But... the good news is that the 30 percent of us who carry the BDNF variant usually maintain their cognitive abilities longer than others if a disease such as Parkinson's, Huntington's, or multiple sclerosis strikes us.
There is no commercially available test to determine if you have the BDNF variant. Sometimes it's better not to know....
But how's your driving?
