Head circumference, biparietal diameter and brain growth in fetal and postnatal life.
The curves for biparietal diameter, head circumference and brain weight with increasing age have different shapes, and these differences have been explained. Interconversion procedures are suggested. One important consequence of changing growth velocities relates to assessing prognosis for catch-up following adversity. On the assumption that catch-up of brain growth must occur within the period of the brain weight growth spurt, the interpretation of head circumference charts is discussed.
