PURPOSE OF REVIEW: As treatment of the leukemias improves, patients are surviving longer. Recognizing and rapidly treating metastatic complications or avoiding neurotoxic therapies improves outcome, reduces morbidity and mortality, and limits long-term sequelae. RECENT FINDINGS: Neurologic dysfunction may result from leukemic infiltration of the nervous system or as a consequence of chemotherapy or prophylactic craniospinal irradiation. The present review summarizes common problems in the neurologic complications of leukemia and discusses recent advancements in their diagnosis and treatment. SUMMARY: Topics covered in detail include central nervous system prophylaxis, leptomeningeal metastasis, and common hematologic complications affecting the brain. The findings aid in the clinical management of patients with leukemia.
