Atherosclerosis of carotid and vertebral arteries: Large vessel stenosis of the carotid or vertebral arteries is the single largest cause of TIAs. Cerebral embolism Embolic sources - Valvular disease, ventricular thrombus, and thrombus formation due to atrial fibrillation Arterial dissection Arteritis - Inflammation of the arteries occurring primarily in the elderly, especially women Noninfectious necrotizing vasculitis (primary cause) Drugs Irradiation Local trauma Sympathomimetic drugs (eg, cocaine) Mass lesions (eg, tumors, subdural hematomas) - Rarely cause transient symptoms TIA etiologies in children, which are different than those in adults, include the following: Congenital heart disease with cerebral thromboembolism (most common) Drug abuse (eg, cocaine) Clotting disorders CNS infection Neurofibromatosis Vasculitis Idiopathic progressive arteriopathy of childhood (moyamoya) Fibromuscular dysplasia Marfan disease Tuberous sclerosis Tumor
