What are the reasons for a child's large head?

Patient's question:

Patient age: One year old
My daughter is only one year old, and her head is a bit larger than that of her peers.

Doctor's answer:

Medical Analysis: Hello, if the child is healthy, with no intellectual or walking problems, and normal limb mobility, then there is nothing wrong with having a large head. If considering medical causes for a large head, it could be due to brain edema or a brain tumor.
Advice: I suggest taking the child to the hospital for an MRI to rule out any medical possibilities. It's often the case that children with larger heads are quite intelligent. Wishing the child good health.
