Etiopathogenic Factors of Cerebrovascular Disease in Young Adults: A Review of the Literature

Cerebrovascular disease (CVD) has been studied for many years, representing a cause of high morbidity and mortality; it has a great impact at a social, economic, and psychological level in the young adult population. There are different etiological factors that we do not find in the adult population, for that it is important to know how to differentiate them. There is no definitive etiological factor in this population given that the epidemiologic profile fluctuates considerably throughout regions and provinces, even if the same country is considered to make comparisons. CVD in young adults is caused by many etiological factors, predominantly the rare ones, such as cardioembolic, small vessel disease, due to thrombophilias, and undetermined cause. Despite being the main cause, the undetermined etiology is overestimated because it deserves for a detailed investigation in search of one of the rare causes, also, because of the lack of more complex studies in centers worldwide. No atherosclerotic large vessels diseases, such as cervicocephalic artery dissection, moyamoya disease, systemic vasculitis, and other rare syndromes should be considered to make an accurate diagnosis approach.
