Cervical artery dissection: A common cause of stroke in young adults.

Cervical artery dissection is a common cause of stroke in young adults and can lead to significant disability. Clinicians should be able to recognize the clinical presentation and diagnose this condition to prevent cerebral ischemia and its complications. Consider cervical artery dissection in a young adult with new-onset, unilateral head pain with or without neck pain with antecedent neck trauma, with or without neurologic deficits or risk factors for dissection. Early diagnosis can lead to better outcomes but the overall prognosis is good for young adults with cervical artery dissection.
