Methods and systems to reduce neurotoxicity associated with the treatment of CD19.sup.+ B-cell hyperproliferative disorders are disclosed. Neurotoxicity is reduced by the use of agents that protect CD19.sup.+ neurovascular pericytes and/or CD19.sup.+ vSMCs from attack by CD19-targeted therapy, and by modification of CD19-targeted therapy to avoid CD19.sup.+ pericytes and/or CD19.sup.+ vSMCs.
