    Neurophysiological testing in children with precocious puberty revealed normal brain stem auditory evoked potentials and visual evoked potentials. Abnormal electroencephalograms (EEGs) in these children may indicate underlying diencephalic disease rather than widespread neurological issues.

    Area of Science:

    • Pediatric Endocrinology
    • Neurophysiology
    • Developmental Pediatrics

    Background:

    • Precocious puberty involves early onset of secondary sexual characteristics.
    • Hormonal imbalances in precocious puberty may raise concerns about neurodevelopmental effects.
    • Central nervous system (CNS) function requires evaluation in affected children.

    Purpose of the Study:

    • To assess neurophysiological function in children with precocious puberty and precocious adrenarche.
    • To investigate potential CNS effects of early hormonal changes.
    • To correlate electroencephalogram (EEG) findings with underlying neurological conditions.

    Main Methods:

    • Recording of brain stem auditory evoked potentials (BAEPs) and pattern reversal visual evoked potentials (VEPs).

  • Performance of electroencephalograms (EEGs) in 19 children (2-8 years old).
  • Clinical evaluation including history and neuroimaging for specific cases.

    • Main Results:

    • All patients exhibited normal BAEPs and VEPs, indicating intact auditory and visual pathways.
    • EEG abnormalities were observed in 7 patients (3 with diffuse slowing, 4 with possible paroxysmal features).
    • No evidence of neurophysiological dysfunction related to hormonal aberrations was found.

    Conclusions:

    • Neurophysiological conduction pathways are generally unaffected in children with precocious puberty.
    • Abnormal EEGs in this cohort are more likely associated with occult diencephalic disease.
    • Hormonal aberrations in precocious puberty do not appear to cause widespread neurophysiological dysfunction.
