Intelligence quotient (IQ) decreases the later the condition is detected and treated. Early detection and timely treatment to prevent this devastating outcome have resulted in one of the great success stories of newborn screening program implementation. Conditions that can cause hypothyroidism in infants are listed in Table 520-1.
