Patient's question:
NoDoctor's answer:
Problems with the fontanelle can be closed after birth or within 3 months. The anterior fontanelle reaches its maximum size by 6 months and gradually shrinks, closing by 1 year of age, with the latest possible closure being at 1.5 years. Premature closure can lead to microcephaly, not only with early closure of the anterior fontanelle but also with a significantly smaller head circumference, which is more than 2 standard deviations below the normal range.
