“...scientists found that playing tackle football before the age of 12 increased the odds of problems with behavioral regulation, apathy and executive functioning later in life by twofold, and the odds of suffering symptoms of depression threefold.”

“Experiencing head trauma at early ages could lead to problems later because young brains are particularly vulnerable. Between the ages of 10-12, says Dr. Robert Cantu, a professor of neurology at BU and a leading expert on head trauma, the brain is maximizing its connectivity and fine-tuning its structural development. Intelligence, mood tendencies, and impulse control are starting to take shape. Repeated hits to the head can only disrupt the cognitive growth process. “They can keep your brain from reaching its genetically-endowed potential,” says Cantu.”
