Very interesting research, and I definitely think it has a basis!
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
