Struggling with post-concussion vision problems? Here is some great advice from Neuro-optometrist Dr. Shirley Blanc.

We say we're fine, even when the truth is we're ecstatic, exhausted, grateful. Or even freaking out. Every time we just go through the motions, we miss out on t...he chance to connect for real. In times of crisis like this, we need each other more than ever. Connecting doesn't just feel good - it's good for our mental health. #mentalhealthweek #mentalhealthawareness

Concussion patients often feel anxious following their injury. Check out this video to find out more about post-concussion anxiety: https://youtu.be/UE3d10FsbQE

In shortpossibly. But only in certain scenarios #Concussions are caused by acceleration (or deceleration) of the brain inside the skull. The brain has two dist...inct layers of tissue (white and gray matter) which are different densities, and thus, accelerate and decelerate at different rates. This causes the two layers to stretch away from one another as well as shear across one another. This is the biomechanics around concussion injuries. Research using accelerometers has found that concussion happens around 95 G’s (with a range between 70-120G) of linear acceleration (Broglio et al.). Reconstructions of football-related concussions found that the head reached peak acceleration within the first 6 to 20ms following impact (Viano et al., 2007). When multiple variables are tested in an effort to reduce acceleration of the head (such as helmet thickness, helmet material, etc.), the best results come from increasing STIFFNESS of the neck. Whaaaaaaat? It makes sensestay with me If the neck had ZERO movement, any hit to the head would require the entire body to move with the head. This would obviously reduce the acceleration of the head because the moment arm would increase substantially. If the neck was completely immobile, it would be likely very difficult to get a concussion at all! Becausephysics So why don’t we all just strengthen our necks?? Well it’s not that simple. You see, a strong neck is only helpful if you are AWARE the hit is coming. Why? Because the peak acceleration of the head happens in the first 6-20 ms, but it takes over 90ms to even initiate contraction of the muscles of the cervical spine and another 150ms to reach even 1/2 of your tensile strength. In other words, if you know the hit is coming a good 1/2 second before impact, then a strong neck may serve you well, however, if you do not know the hit is coming (which is the VAST majority of concussions), then the #concussion has occurred before you’ve even started to contract that big strong neck you’ve been working so hard on. #stiffnessnotstrength
