Baby Large Head Circumference
Depends on gender ;: Velocity of growth. Has the head circumference grown normally along a single curve between 5th-95th%ile or increased too rapidly, e.g., jumping from 25th to 95th %ile (as may be seen in autism or hydrocephalus), or too slowly, e.g., dropping from 25th to 5th%ile, (indicating insufficient brain growth)? Girls' range at 9 months is 41.6-46.6 cm; avg. Is 44 cm. Boys, 43-47.4 cm; avg. Is 45.4 cm. ...Read more
Large heads in infancy need to be followed by pedi MD over time. By itself, can be due to parental large head. If it is out of range and no family history and other things are occurring, i.e. delayed speech and behaviors this can be a soft sign to autism spectrum disorders. If increasing head size over time, can also be due to CSF fluid leaks causing that ...Read more
17 wk old niece head circumference is on 99th percentile.50th percentile for height and weight. Is this a problem? Her mother has quite a large head.
Is there a correlation between abnormally large head circumference and an increased chance of neonatal seizures?
Yes.: Weight varies with height. But head size has nothing to do with height or weight. So although it is possible that someone's body could grow to match their large head, there is no guarantee it will happen. Further, the percentage of your body length that is your head is about 30% at birth, but only 10% as an adult, so babies tend to have bigger heads than adults. ...Read more

Relative study: His rating means that 10% of infants at this age have a larger head circumference (size) while 90% are smaller.If the size has increased from 25-50-75-90% over several months it would suggest growth was too rapid. If usually in that range, it just means the kid has a big head. It hasn't bothered me any, except for having trouble finding a helmet/hat that would fit. ...Read more

My child was diagnosed with macrocephaly.
I took her in to get an MRI done It came back normal. Is her head going to be abnormally large when teenager?
Error in dates / Pbm: Having a large head is relative. If you are supposed to be "x" weeks along you are supposed to have a head of a certain size, if your head is bigger, you might be further along. You might also have a developing problem in your head, but that is where a more specific ultrasound or interpretation by a specialist needs to be considered. ...Read more
Macrocephaly: Macrocephaly is diagnosed when the circumference of the head is more than two standard deviations above average for the child's age, sex, race, and period of gestation and may be caused by many conditions. Macrocephaly would be the diagnosis if the ofc (occipito-frontal circumference) is >90%ile for his age and gestation. ...Read more

Genetics: There are by definition 3% of the normal adult population that are classified as having an over sized head & 3% that would be considered small. When I see it in a kid i usually find either mom or dad has one as well. There are syndromes & birth defect (hydrocephalus) that can also produce a large head, but by far the largest group just inherited the feature. ...Read more
Depends on situation: For many, it means you have a genetically larger head size, as I do, making finding a hat that fits a bit difficult. For some infants, it can mean a build up of pressure within the skull caused by abnormal fluid flows within the brain, requiring a surgical procedure. ...Read more

Can a Thin Person have a Large Head, or does he need a smaller equal size head to adapt to his Body?
Large head: Our head size is more influenced by genetics than it is by our body size. Although as kids we go through a stage of having big heads, later on body and head will seem more proportional. ...Read more

A 4 months: Old should be holding his head without head lagging unless ex-premie, then need to correct age.

Maternal age 35 yrs. 36 weeks pregnant. Large head parameters within physiological range bpd 9.24. Single loop of cord around neck.? El lscs or vd
10 week old baby length and weight both 85th percentile. Head circumference 95th percentile. Does this mean he has a big head in proportion to body?
Not really: I don't consider that difference worth anything more than noting. Big babies are big all over and this falls within the normal variation of such measurements. If the kid was 50% weight/length and 95% head, I would just measure the parents head to see where baby inherited it from. There are other issues to consider with a big head, but not from the reported info. ...Read more
Is there any means of treating macrocephaly. I'm 6ft 3" 24 years old and my head is 63cm in diameter. I've only noticed its size in the last 3 years.?
Other Sx ???: By definition, you have a big head circumference. It is likely one of your parents do too. If you've lived this long and had no problems other than finding a hat that fits, ignore the issue & live your life knowing you fall in the top 3% in something. If you think the size is increasing, have unexplained headaches, etc. See your doc. You only beat me by 2 cm. ...Read more
Impatient because her head is still swollen! And is macrocephaly (enlarged head) a correct diagnosis for fluid in the brain, what to do?
Can't advise : This is really not something that a physician that is not involved in her care can comment on. I see you are from NYC. Some very best neurosurgeons practice in NY. I'd follow their advice, and get a second opinion if you aren't sure about the recommendation. ...Read more
I m concerned for baby head growth. She is 18 days old. Born with 37 CM head circumference today 40 cm.is that normal.
Large head: 40 cm at 18 days is large. IF there is no bulging of the fontanelle, the difference may be due to molding durign the delivery. Was this a large baby? Is there a family history of large heads. If there is any concern, speak to your pediatrician andi f necessary have an ultrasound done. ...Read more
