● Support normal growth and skeletal maturation
● Influence nervous system myelination and maturation
Cardiovascular Effects
● Increase heart rate and cardiac contractility
● Enhance cardiac output
● Lower systemic vascular resistance
● Optimize blood pressure regulation
Neurocognitive Effects
● Support cognitive function and mood regulation
● Influence neuronal development and signaling
● Regulate neurotransmitter function
The Rockwell approach recognizes that these diverse effects
explain why thyroid dysfunction can manifest with such
wide-ranging and often subtle clinical presentations [8].
Thyroid Function Tests: The Rockwell Perspective
Standard Laboratory Assessment
Conventional medical practice typically relies on a limited panel
of tests to evaluate thyroid function, primarily:
● Thyroid Stimulating Hormone (TSH)
The most sensitive indicator of thyroid function in primary thyroid
disorders
● Free T4 (FT4)
Measures the unbound, biologically active fraction of T4
