Gross motor development is widely considered to be the result of innate, biological factors, with postnatal factors co… For example, folic acid intake of 400 micrograms (mcg) daily for three months prior to conception and during early pregnancy significantly decreases the risk of certain birth defects of a baby’s brain (anencephaly) and spine (spina bifida).. The development of the disabled child and future life chances, including those of siblings, are critically affected by the support and services received by the disabled child and their families during the early years following diagnosis. Another commonly known issue is that of folate deficiency, which can cause various neural tube defects, such as spina bifida. Proper nutrition is a vital factor in a child’s overall development. Developmental disabilities are a set of physical and mental conditions that cause an impediment in the normal functioning of various biological systems in the human body. Evidence is increasing, however, that chemicals in the environment are contributing to changing patterns of disease in children, the wide prevalence of neurodevelopmental disabilities such as ADHD and autism, increasing rates of asthma and certain childhood cancers, and, possibly, disorders of endocrine function and reproduction. It is characterized by rapid development, particularly of the brain, where connections between brain cells are being made to provide the necessary building blocks for future development.
