Answers

(1) Drug-resistant epilepsy, not associated with acute brain complications or CNS leukaemic involvement, is a rare complication in survivors of ALL, with only few cases reported in the literature.


(2) Generalized epileptic encephalopathies, such as Lennox Gastaut syndrome, and multifocal and focal epilepsies (associated with hippocampal sclerosis or radiation-induced cavernous angiomas) are described.


(3) It has been postulated that the main neurotoxic agents related to the CNS oncological treatment are intrathecal methotrexate and brain radiotherapy.
