Transcranial magnetic stimulation in children.

Area of Science:

• Neuroscience
• Pediatric Neurology
• Developmental Biology

Background:

• Developmental disabilities often involve atypical motor skill maturation.
• Neurophysiologic tools like transcranial magnetic stimulation (TMS) offer insights into motor cortex function.
• Understanding neuromotor maturation is key to developing interventions for childhood disorders.

Purpose of the Study:

• To review the existing literature on the application of TMS in pediatric populations.
• To explore the potential of TMS-derived parameters in understanding typical and atypical neuromotor development.
• To assess the utility of TMS in identifying disease burden and treatment efficacy in children.

Main Methods:

• Systematic review of studies using TMS in pediatric populations.
• Analysis of TMS-evoked parameters in typically developing children and those with neurological disorders.
• Comparison of TMS findings with other neurophysiologic modalities like fMRI.

Main Results:

• TMS-evoked parameters demonstrate age-related changes in typically developing children.
• Certain TMS parameters are altered in children with various neurological disorders.
• No single TMS parameter is currently diagnostic for any specific disorder.

Conclusions:

• TMS parameters can reflect disease burden and may indicate treatment response in pediatric neurological conditions.
• Combining TMS with other modalities like fMRI may enhance its utility.
• Further research is needed to establish TMS parameters as reliable biomarkers for disease progression and intervention efficacy.
