| Anti-CD19 CAR T-cell therapy |
Classical early ICANS: encephalopathy, aphasia, seizure concern, EEG slowing |
Structured inpatient monitoring remains central; low threshold for early EEG when exam fluctuates. |
Consensus grading, EEG studies, pediatric neurotoxicity cohorts, CNS lymphoma meta-analysis, and product-specific safety context (1, 8–10, 21–26) |
| CD3-engaging bispecific antibodies |
Usually lower-grade neurotoxicity than CAR T, but recurrent exposure and step-up dosing create repeated risk windows. |
Safe use depends on observation systems, explicit escalation pathways, and—where adopted—mitigation strategies such as prophylactic tocilizumab. |
Meta-analyses, outpatient roadmap, prophylaxis cohort, and real-world teclistamab studies (4–6, 13–16, 27) |
| BCMA-directed CAR T-cell therapy |
Early ICANS plus delayed movement/neurocognitive syndromes, including Parkinsonism-like presentations |
Extend surveillance beyond initial recovery; specifically ask about gait, bradykinesia, executive decline, and late confusion. |
CARTITUDE movement/neurocognitive reports, delayed case literature, rescue reports, and ide-cel toxicity analyses (12, 17–20) |
