XSIQ * Health and Human Development - Summary of development across the lifespan Summary of development across the lifespan Over a lifespan, development occurs with a certain predictability. However, variables such as socioeconomic levels, nutrition and level of education influence development. PRENATAL Increase in number and size of nerve cells to attain 25% adult brain weight and size at birth. Brain is particularly susceptible to teratogens in weeks 3 to 5 in the embryonic period. INFANCY Extensive and rapid growth. CHILDHOOD Slows down. 75% of adult sized brain at age 3 and brain reaches maximum size by age 10. ADOLESCENCE Nerve connections and associations continue to build up. Myelination continues. ADULTHOOD No likely change to capacity. LATE ADULTHOOD 65-70 year olds in an industrialised country have lost 20% of nerve cells that were present at birth. This leads to less acuity but not capacity. Development across the lifespan.
