Cognitive, Brain and Intracranial Artery Involvement in Beta Thalassemia

Background: Brain involvement in beta thalassemia is scarcely known so far, and available data show different degrees of abnormalities in terms of neuroradiologic findings and cognitive impairment, mainly showing asymptomatic white matter lesions in transfusion dependent thalassemia (TDT; Karimi et al, Ann Hematol 2016) or in non transfusion dependent thalassemia (NTDT; Karimi et al, Ann Hematol 2012; Pazgal et al, Thrombosis Research 2016), arterial stenosis in NTDT (Musallam et al, EJH 2011) and a general impairment in cognitive function in TDT (Elalfy et al, Hematology 2017). To our knowledge there are no studies investigating neuroimaging and cognitive function in both groups of patients, comparing results to healthy subjects.
