Causes of ADHD

Attention-deficit/hyperactivity disorder (ADHD) is the most common behavioral disorder among the children, affecting approximately 5 to 12 percent of the school age population. A child diagnosed with ADHD exhibits increased irritability, restlessness, overactivity, as well as age-inappropriate inattention. Many parents face the burden of caring children with ADHD. Oftentimes, these children are difficult to deal with. Their relationship and other social interactions are affected. Due to lack of focus and interest to engage in activities requiring concentration, these children have poor school performance.

Parents should bear in mind that although children with ADHD experience difficulty in coping up with their school activities and social interactions, they are also capable of succeeding. This chance depends on the parents themselves. In order for the parents to meet the needs of their children, it is important for them to understand the nature of this behavioral disorder. Through this, parents will be able to freely accept the condition of their children. It is important for parents to know what causes ADHD. Unfortunately, the exact etiology of this condition has not yet been identified but research studies point out several factors that may cause the occurrence of ADHD.

According to some studies, there is a close association between ADHD and the environment. Some cases of ADHD are found in children whose mothers smoke cigarettes heavily and consume alcoholic beverages. Therefore, it is important for a pregnant mother to refrain from these activities when carrying a child in her womb. Heavy metal toxicity such as lead poisoning is also one of the possible factors in the development of ADHD. This is the reason why toys and other home furnishings are banned from being lead-painted. Many other health problems, particularly growth and developmental problems can result to lead poisoning.

Trauma and injuries to the head during childbirth has also been attributed to ADHD. According to some studies, children who experienced brain injuries as a result of accidents during their early years in life can lead to this behavioral disorder. However, studies show that there are only small portion of the population of ADHD children who experienced any traumatic brain injuries during their childhood. Other studies also suggest that using certain food enhancers, preservatives and refined sugar can cause ADHD. In some cases, increased consumption of these food substances can exacerbate symptoms of ADHD.

Most researchers agree ADHD is more likely associated with genetic predisposition. According to them, children who are diagnosed with ADHD have siblings, parent or other close relatives who are also experiencing the same behavioral disorder. For some scientists, they attribute ADHD with the anatomical structure of the brain. Although what causes ADHD may remain unknown for years, experts still continue to conduct studies and researches in the intent of knowing the exact etiology of this behavioral condition.
