Soft Spot On Top Of Head (Definition)

In an infant, the space where two skull-bone sutures join forms a membrane-covered "soft spot" called a fontanel (fontanelle). The fontanels allow for growth of the skull during an infant's first year. The fontanels should feel firm and very slightly curved inward to the touch. A tense or bulging fontanel occurs when fluid builds up in the skull cavity or when pressure increases in the brain (increased intracranial pressure).

My anterior fontanelle was prematurely closed shortly after birth b/c i was a premie. Does this mean I have craniocynostosis?

No: The closure of the soft spot does not define craniosynostosis.It can be undetectable in size or as large as a grapefruit and the kid turn out fine.It is the behavior of the skull bones define a problem.If they fuse, not just close in , a person will have a ridge develop at the point of fusion and abnormalities develop in the shape of the head, that is craniosynostosis. ...Read more

4-26 months is the: Range of closure of the anterior fontanelle. If he has no increased intracranial pressure, congenital hypothyroidism, or skeletal anomalies, it's probably an "outlier." early-onset hyperactivity is seen with family history of adhd, prenatal exposure to drugs & alcohol, & some genetic syndromes.
