How do you get a concussion and what can you expect?
- May be caused by a direct blow to the head, face, neck or elsewhere on the body with an “impulsive” force transmitted to the head. You do not need to hit your head to receive a concussion; it can be caused by a whiplash or acceleration/deceleration of the body/head/neck
- Concussions typically result in a rapid onset of short-lived impairment of neurological function that resolves spontaneously. In some cases, the signs and symptoms may evolve over minutes to hours
- Concussions can result in neuropathological changes, which reflect in a functional disturbance not a structural injury. Most often, no abnormalities are seen on standard neuroimaging (i.e., CT scan, CAT scan, MRI etc)
- Concussions result in a graded set of clinical and cognitive symptoms that typically follow a sequential course. However, in some cases the symptoms may be prolonged
- Duration of symptoms is highly variable and may last from several minutes to days, weeks, or months and even longer in some cases
