True about head circumference measurement

[Medicoman]

True about head circumference measurement –

• 1. Measured in supra–orbital ridge
• 2. Measured hydrocephalus/microcephaly
• 3. Serial measurement is useful
• 4. Helps in measurement of neurological development
• 5. All of these

exp:

Options 'a’

• Head circumference is measured from the occipital protuberance to the supraorbital ridge on the forehead.

Option 'b’

• If the head circumference growth exceeds 1 cm in 2 weeks during the first 3 months, hydrocephalus should be suspected.
• In microcephally head circumference is two standard deviation below the mean for age and sex.

Option `c, d, e’

• Head circumference measurements that progressively drop to lower percentiles with increasing age are indicative of a process or condition that has impaired the brain’s capacity to grow.
• So, serial measurement helps to assess neurological development and pediatric intelligence.
