What Causes Attention Deficit Hyperactivity Disorder?

The cause of ADHD is still unknown. There is no official research or studies finding the cause ADHD to child or adult but there are hypotheses. They say that watching too much TV, eating sugar, or poor school or education are the causes of ADHD, but there is not enough research to support these claims. 1

Researches have recognized that there are many factors that may cause ADHD. Although sometimes parents blame themselves on how they raise their children as the reason for having ADHD, it can be assumed that ADHD can be hereditary. About one in four children with ADHD has at least one relative with the disorder. Plus, it is more likely that if one of the identical twins has ADHD, the other one could have the disorder as well.

Other factors that may play a role in ADHD is the chemical imbalance that leads adults and children with ADHD to have low levels of dopamine (dopa decarboxylase) which sends messages to a part of the brain that is concerned in attention, movement and motivation.

The environment also plays an important role for a child and the possibility of having ADHD. Children who are exposed to some environmental toxins like lead and PCBs (polychlorinated biphenyls) have a greater risk of having problems in their development as well as behavioral concern. Some children who are diagnosed with ADHD could have been exposed to these toxins. Plus, if pregnant women are exposed to PCB, there is a possibility that their child will show symptoms of ADHD. Also, alcohol drinking and smoking by pregnant women may increase the chance of having children with ADHD, as it may reduce activity of the neurons that produce dopamine. 2
