Causes of developmental delay can be difficult to pinpoint, and a variety of things can contribute to it. A timely intervention will improve developmental outcomes and the family’s adjustment.

Dependent upon level of exposure lead can lead to reduced IQ, behavioural changes such as reduced attention span, increased antisocial behaviour and reduced educational attainment.18 Natural exposure occurs in soil but pollution, leaded gasoline, paint products, pesticides and industrial activity can raise lead levels in the air, soil and water sources.17 In developing countries there are fewer pollution controls and the use of older ceramics and some traditional medicines also increase the exposure to toxins such as lead. Fetal alcohol spectrum disorders (FASDs) are a group of conditions that can occur in a person whose mother drank alcohol during pregnancy. The virus causes neuronal damage and cell death, leading to progressive encephalopathy with motor disabilities, as well as to microcephaly and brain atrophy, with cognitive and language delays. These infections can affect a child in utero, should a mother be infected, or in a child’s early years. Iodine deficiency is considered by the WHO to be the leading and most preventable cause of brain damage worldwide.21 A component of thyroid hormones, iodine is essential for brain development, particularly from the second trimester of pregnancy through the third year of life.

Once, scientists thought that all learning disabilities were caused by a single neurological … Storage in teeth and bones accumulates over time and may be remobilized during pregnancy.18 Undernourished children are more susceptible to lead because their bodies absorb more lead if other nutrients such as calcium are lacking.
