Neurological complications of beta-thalassaemia major.

Neurological complications in beta-thalassaemia major are uncommon, with cerebral ischaemic episodes related to severe anaemia or convulsions as the most usual manifestations. Two such cases of children of 6 and 8 years are reported. Cerebral venous infarction is advanced as the probable cause of the symptoms. Caution should be exercised in giving rapid, large blood transfusions to thalassaemic patients adapted to long-standing severe anaemia.
