For Katherine Price Snedaker, a Norwalk social worker and mother of three, her expertise in concussions has been hard-won. Her number of concussions is in the double digits, starting with her first diagnosed ones at age 16 and 19 from separate car accidents. There was no follow-up care, she said, and only recently has her plea for more attention for female concussions been gaining traction. Snedaker is executive director of PinkConcussions.com, a nonprofit devoted to the latest research on concussions among women. She’s also the founder of SportsCAPP.com, a youth sports concussion educational organization, and she is an associate member of the National Sports Concussion Coalition.
