    Area of Science:

    • Neurology
    • Pediatrics
    • Immunology

    Background:

    • Myasthenia gravis (MG) is a neuromuscular disorder affecting neuromuscular transmission.
    • Distinguishing between autoimmune and congenital forms of MG is crucial for patient management.

    Observation:

    • This study reviewed 11 children with myasthenia gravis symptoms by age 3.
    • Six patients had persistent neonatal myasthenia gravis (a non-immunological familial disorder).
    • Five patients had juvenile onset myasthenia gravis (an autoimmune disorder).

    Findings:

    • Juvenile onset myasthenia gravis, previously thought rare in early childhood, was observed in 5 of 11 young patients.
    • The availability of anti-acetylcholine receptor antibody assays aids in differentiating autoimmune MG from congenital forms.

  • Autoimmune myasthenia gravis may be underdiagnosed in children under 3 years old.

    • Implications:

    • Early and accurate diagnosis of myasthenia gravis subtypes is vital.
    • Distinguishing between autoimmune and congenital MG impacts treatment strategies and prognosis.
    • Increased awareness of juvenile onset myasthenia gravis in young children is warranted.
