Anti‑NMDA Receptor Encephalitis #
Anti‑NMDA Receptor Encephalitis
Definition #
A rare autoimmune encephalitis in children caused by antibodies targeting the N‑methyl‑D‑aspartate (NMDA) receptor, leading to psychiatric symptoms, seizures, and movement disorders. Early recognition allows prompt immunotherapy, which can reverse neurologic deficits. Challenges include differentiating it from primary psychiatric illness and securing timely antibody testing.
Antisense Oligonucleotide Therapy #
Antisense Oligonucleotide Therapy
Definition #
Short, synthetic nucleic‑acid strands designed to bind specific mRNA transcripts, reducing pathogenic protein production. In pediatric neurology, ASOs such as nusinersen have transformed the management of spinal muscular atrophy by increasing SMN protein levels. Major challenges involve intrathecal delivery, long‑term safety monitoring, and cost considerations.
Autologous Hematopoietic Stem Cell Transplantation (aHSCT) #
Autologous Hematopoietic Stem Cell Transplantation (aHSCT)
Definition #
A procedure in which a child’s own stem cells are harvested, the immune system is ablated with chemotherapy, and the cells are reinfused to reset auto‑reactive immunity. AHSCT is investigated for refractory autoimmune neurologic disorders such as multiple sclerosis and neuro‑Behçet disease. Risks include infection, organ toxicity, and uncertain durability of neurologic improvement.
Brain‑Derived Neurotrophic Factor (BDNF) Modulation #

It is approved for pediatric NMOSD and has shown efficacy in preventing relapses. Considerations involve heightened infection risk, especially meningococcal disease, and lifelong vaccination requirements.
Enzyme Replacement Therapy (ERT) #
Enzyme Replacement Therapy (ERT)
Definition #
Intravenous infusion of functional enzymes to compensate for genetic deficiencies, as in Gaucher disease or mucopolysaccharidosis. While systemic manifestations improve, central nervous system involvement often persists due to limited enzyme crossing of the blood‑brain barrier, prompting research into intrathecal delivery and modified enzymes.
Fetal Gene Therapy #

Definition #
Controlled reduction of core body temperature to 33‑35 °C for 72 hours after hypoxic‑ischemic insult, limiting excitotoxic cascades and inflammation. While standard for term neonates, application to older children after traumatic brain injury is experimental, with concerns about coagulopathy and infection.
Optogenetic Modulation #
Optogenetic Modulation
Definition #
Genetic introduction of light‑sensitive ion channels into specific neuronal populations, allowing precise activation or inhibition with patterned illumination. In mouse models of pediatric epilepsy, optogenetics has terminated seizures on demand. Human translation faces challenges in safe light delivery and long‑term expression.

Definition #
Surgical implantation of a cuff electrode around the left vagus nerve delivering intermittent electrical pulses. In children with drug‑resistant epilepsy, VNS can achieve ≥50 % seizure reduction in many cases. Adjustments to stimulation parameters are required as the child grows, and device replacement surgery is needed every 5‑7 years.
Wnt Signaling Pathway Modulators #
Wnt Signaling Pathway Modulators
Definition #
Agents that influence the Wnt/β‑catenin cascade to promote neuronal differentiation and synaptic formation. Experimental therapies aim to correct developmental anomalies seen in conditions like lissencephaly. Precise dosing is essential to avoid oncogenic activation.
