When a baby's head is too big, it is called macrocephaly.
Understanding Macrocephaly
Macrocephaly, meaning "large head," is a condition where an infant's head circumference is significantly larger than that of other infants of the same age and sex. Specifically, it is defined as a head circumference that is greater than the 97th percentile.
How is it Diagnosed?
A diagnosis of macrocephaly involves measuring the circumference of a baby's head. The measurement is taken around the widest part of their head and is compared to standardized growth charts that account for age and sex. If the measurement falls above the 97th percentile, the baby may be diagnosed with macrocephaly.
Key Points About Macrocephaly
- Definition: A larger than average head size for an infant.
- Measurement: Determined by measuring the circumference of the head.
- Percentile: A measurement greater than the 97th percentile is considered macrocephaly.
- Comparison: Measurements are compared against growth charts specific to age and sex.
What to Do
If your baby is diagnosed with macrocephaly, it's important to work closely with your child's pediatrician. This will help monitor the situation and determine if further testing or action is needed.
