In honor of CTE Awareness Month, Dr. Michael Alosco from the Boston University CTE Center is sharing a key truth about CTE.

CTE isn’t shaped by one or two concussions.
It develops after thousands of repetitive head impacts over time.

Every hit matters. Understanding this shifts the focus from isolated injuries to long-term exposure, and underscores why prevention and limiting repeated head impacts is so important.
