Macrocephaly In Babies: Big Head in Babies

August 12, 2021

Macrocephaly is a medical condition where a baby’s head is unusually larger than other infants of the same age and gender. While the condition may be harmless or benign in most cases, it may indicate an underlying medical condition like a brain tumour or genetic syndrome in some babies. In some cases, macrocephaly head circumference is caused due to family history. This is often diagnosed as benign familial macrocephaly. Other than the larger than normal size of the head, this does not lead to any additional health concerns. However, if the condition is due to a fluid build-up in the infant’s brain, it will require immediate medical attention. This extra fluid will place undue pressure on the brain leading to several health complications.

  • Certain metabolic conditions
  • Brain tumours
  • Some types of infection
  • Greig cephalopolysyndactyly syndrome
  • Chronic hematomas
  • Alexander disease
  • Sotos syndrome
  • Other genetic syndromes

Symptoms Of Macrocephaly

Although the primary symptom of macrocephaly is a larger than usual head, it may also be accompanied by other symptoms, which will help doctors identify the underlying medical condition.


  • A fast-growing head
  • Delay in reaching different developmental milestones
  • Comorbidity
  • Autism
  • Epilepsy
  • Mental disorders


The doctors will also ask parents to keep an eye out for other signs like excessive sleepiness, poor feeding, unusual eye movement, vomiting, extreme irritability or a bulging soft spot.


Although the macrocephaly definition may seem to scare parents, finding the cause behind the condition will help doctors come up with a treatment plan. The treatment measures differ from case to case and may include surgery, oral medication, occupational therapy, speech therapy, physical therapy and behavioural therapy. Babes with familial macrocephaly grow up with no major problems and do not require any treatment as such.
