Vascular Brain Damage in Thalassemia Syndrome: An Emerging Challenge.

Thalassemia syndromes are the most prevalent monogenic hemoglobinopathy in the world. In Iran, thalassemia is a public health problem because this country has been located on the thalassemia belt. In recent decades, considering that the life expectancy of patients with thalassemia has dramatically improved, some unrecognized complications have emerged in these individuals. One of these complications is a hypercoagulable state that may lead to thromboembolic events (TEE). The TEE may involve any organ in the body, including the central nervous system. Ischemic cerebrovascular events in thalassemic patients have been divided into two categories, namely overt stroke and silent cerebral infarcts (SCI). Overt stroke often develops in patients with beta-thalassemia major; however, patients with thalassemia intermedia usually suffer from SCI. This review article discusses brain vascular involvement.
