The [American Medical Society for Sports Medicine](https://journals.lww.com/cjsportsmed/Fulltext/2013/01000/American_Medical_Society_for_Sports_Medicine.1.aspx) clearly pointed out in their position statement from 2013 that neither helmets nor mouth guards protect you from concussions. Helmets protect your skull from getting cracked but the brain will still smash into your skull when you get hit. Mouth guards are for dental protection. The [AMSSM](https://www.amssm.org/) concludes that the best way to prevent concussions in sports is to change the behavior on the field and to change the rules to reduce the impact. As an individual you can now monitor how well you are doing by using novel smart technologies such as embedded [head-impact sensors in your mouthguard](https://www.sisuguard.com/sisusense/). Awareness of head-impact will make you adjust properly, and ultimately, hope that most violent games will change. Until then, we need to know what to look for if you suspect a concussion, especially if you play sports like football, ice hockey, lacrosse and field hockey. A research team from Virginia Tech showed that a high school football player receives 565 hits/season on average; 5% of which are over 50G. We also know that all the “minor” hits can accumulate over time. So, as a player, coach or parent you need to be alert and look for symptoms. These are signs [CDC](https://www.cdc.gov/) suggests you should look for in a player that could signal a concussion: - Can’t recall events *prior to* or *after* a hit or fall. - Appears dazed or stunned. - Forgets an instruction, is confused about an assignment or position, or is unsure of the game, score, or opponent. - Moves clumsily. - Answers questions slowly. - Loses consciousness *(even briefly)*. - Shows mood, behavior, or personality changes. And these are the more severe symptoms a player with a clinical concussions may have: - Headache or “pressure” in head. - Nausea or vomiting. - Balance problems or dizziness, or double or blurry vision. - Bothered by light or noise. - Feeling sluggish, hazy, foggy, or groggy. - Confusion, or concentration or memory problems. - Just not “feeling right,” or “feeling down”. Many of these signs and symptoms occur right after the hit to the head, but they can develop hours or even days later. You can also accumulate hits that matter over time, and way down the road you may start having headaches and other symptoms. This is more common in lower impact sports like basketball and soccer. Just remember, whenever you are worried about a possible concussion you should to see a doctor.
