What happens when you have a concussion?

What primarily causes a concussion?

• A chemical imbalance in the brain

• Neurons stretching or tearing after the brain jolts and hits the skull

• An infection inside the protective membranes

• Lack of sleep after head impact

Which of the following is NOT a common symptom of a concussion?

• Blurry vision

• Balance problems

• Increased appetite

• Memory and thinking difficulties

The video describes "post-concussion syndrome (PCS)". What increases the likelihood of developing PCS?

• Resting completely for several weeks after injury

• Playing through a concussion or returning to sports too soon

• Immediately sleeping after a concussion

• Taking anti-inflammatory medication right away

What did Diffusion Tensor Imaging (DTI) studies of soccer players who head the ball frequently find?

• No measurable changes in the brain structure

• Structural damage to axon bundles and worse short-term memory performance

• Immediate concussions after each header

• That tau protein clumps decreased with more headers

What is the role of tau protein in CTE development?

• Tau proteins repair damaged microtubules and prevent disease

• Tau proteins dislodge and clump after repeated subconcussive hits, disrupting neuron transport and spreading damage

• Tau proteins are unrelated to brain injuries and only affect muscles

• Tau proteins instantly cause dementia after a single concussion
