Head circumference percentile adults
Due to the way percentiles are calculated, by definition approximately 10% of a population should be <10th percentile (small head circumference), approximately 80% between the 10th and 90th percentiles (normal head circumference), and approximately 10% >90th percentile (large head circumference).Head circumference correlated to adult brain volume without dementia, and it is a non-invasive, fast, and inexpensive method to indirectly measure child or adult brain volume. As HC remains constant across the life span, these results suggest that microcephaly might be a risk factor for dementia at old age, as structural changes in the brain ...

However, there is considerable variation in forearm length, mainly due to height. To illustrate, the table below shows forearm length percentiles for both genders. The 50th percentile is the average ...Among these measurements, the growth of the brain can be monitored by means of head circumference, because cognitive function, intracranial volume, and brain volume are closely related to the magnitude of head circumference [4-6]. In addition, many medical problems, including various syndromes, may be related to microcephaly and macrocephaly.Abstract.
