    The newly identified nuchocephalic reflex is linked to brain function. Its presence in adults may indicate cerebral dysfunction, while in children, it typically disappears by age four.

    Area of Science:

    • Neuroscience
    • Neurology
    • Developmental Neuroscience

    Background:

    • The nuchocephalic reflex is a newly described reflex.
    • Its developmental trajectory and clinical significance remain largely uncharacterized.

    Purpose of the Study:

    • To investigate the nuchocephalic reflex in a diverse age group.
    • To determine the reflex's correlation with cognitive function and cerebral dysfunction.

    Main Methods:

    • A controlled study involving 146 subjects aged 11 hours to 94 years.
    • Assessment of the nuchocephalic reflex.
    • Cognitive assessment using a shortened Wechsler Adult Intelligence Scale for subjects over 16.

    Main Results:

    • The nuchocephalic reflex was uninhibited in infants and typically inhibited by age 4.

  • In adults (>16 years), the reflex presence correlated with diffuse cerebral dysfunction.
  • The reflex demonstrated sensitivity as an indicator of higher cortical function status in adults.

    • Conclusions:

    • The nuchocephalic reflex exhibits distinct developmental patterns.
    • Its presence in adults serves as a sensitive indicator of higher cortical function and potential cerebral dysfunction.
    • The predictive value of the reflex varies across different adult age ranges.
