What is concussion?
A concussion is a type of traumatic brain injury that is caused by a bump or jolt to the head or by a hit to the body that causes the head and brain to move back and forth rapidly.
Signs of a concussion may include symptoms such as headache, nausea, dizziness, brain fog, memory issues, mood swings, confusion, vomiting, fatigue and loss of coordination. While concussion may result in you being unconscious, you can have concussion while being conscious.
A lot of concussions will spontaneously heal in two weeks, but 20-30% of people have ongoing symptoms that last longer than the expected recovery time (one to two months), which is termed post-concussion syndrome.
