<unk>  has been noted to be a common cause of young adult strokes, with some sources indicating a prevalence of up to 20% in this young adult population with annual incidence rates between 2.6-2.9 per 100,000, although these incidences may be misleading with true incidences being higher because clinical presentations can vary, many being minor or self-limited, and thus these dissections can go undiagnosed. In population-based studies, the peak age of presentation is approximately 45 years with a slight gender predisposition towards males (53-57%).<unk>  arteries, as mentioned above, are comprised of two pairs of arteries: vertebral and carotid. As such,<unk>  can be further categorized based on the involvement of artery: carotid vs. vertebral, and the location of the dissection: intracranial vs. extracranial.
