What Causes ADHD?

What causes Attention-Deficit Hyperactivity Disorder or ADHD? Despite advances in ADHD studies, the cause is still generally unknown. However, scientists believe that it has something to do with the genetic make-up of a person-genetic, in a sense, because the chemicals in the brain known as neurotransmitters are different than those with ADHD.

Causes of ADHD

There are some cases in which mothers who smoked or drank alcohol during pregnancy had children with the said condition. That goes as well for mothers who had difficult pregnancies.

Low birth weight, head injuries sustained in the frontal lobe of the brain or exposure to lead and other environmental chemicals for babies are said to increase risks of ADHD.

Moreover, the disorder can be passed down by fathers to their children genetically. Almost 1/3 of fathers with ADHD tend to have children with the said condition. Similarly, the same thing happens in cases where both parents have ADHD.

The Role of the brain

As shown in recent studies, children with ADHD tend to have brains that function rather abnormally as there is problems regarding nerve pathways.

In addition, there are cases when some parts of the brain are smaller than those with no ADHD. Dopamine, a brain chemical that is linked with brain functions such as movement, sleep, attention, learning and mood, also plays a factor in the acquisition of ADHD. Adults with this disorder tend to have a lethargic flow of dopamine in their system.

This is the reason why medicines like Ritalin and Adderall have been proven to be beneficial to those with ADHD because it stimulates dopamine production.

The same thing goes for nicotine and cocaine. In fact, the hypothesis is that people with ADHD tend to abuse substances. Fortunately, in recent studies, it has been proven that ADHD cannot be acquired by watching too much television as past researches have claimed.
