Can abs braking cause or worsen a concussion? My abs braking system stopped my car going about 60mph. I don’t have any effects from the seatbelt and aside from being shaken up I felt okay. I did sustain a concussion 3 months ago and have some PCS symptoms and anxiety. I did talk to a neurologist online (that’s how the appts are now) and they did say sudden braking can cause/worsen concussion. I guess I’m looking for any experiences with this as I really don’t want to be back where I was two months ago and go backwards in my healing. Thanks!
