Causes of ADHD- Why is ADHD caused?

Neurological diseases and diseases related to the brain are difficult to treat and comprehend. Neurologists, psychologists, psychiatrists and medical researchers, despite great studies, know very little about the human brain. Thus a great deal of research and study is required to ascertain the nature of the mental disease that a person is suffering from. The case is no different for ADHD.

What is ADHD?

Attention Deficit Hypersensitive Disorder or ADHD is a neurological disease which mainly affects children. A child is supposed to be suffering from ADHD when he shows signs of extreme restlessness, hyperactiveness, anxiety and impulsiveness. Children suffering from ADHD show these signs very regularly and under all the situations. These children lack the capacity to pay attention for a long time and can be easily distracted.

Causes of ADHD:

The exact cause of ADHD is not yet known. However experts believe that the following reasons might be the factors responsible for ADHD:

1) Experts believe that ADHD is biological in nature and is caused primarily due to a chemical imbalance in the brain.
2) Genetic factor can also be a chief cause for ADHD as per the experts' opinion. It has been observed that parents suffering from ADHD have children suffering from it too. Thus hereditary cause is also a prime reason for ADHD.
3) Identical tins show a tendency of suffering from ADHD more than the fraternal twins, even if the twins are raised separately.
4) There are other non-genetic factors responsible for causing ADHD. Other environmental factors like the child being exposed to toxic elements like lead or complications during pregnancy like insufficient oxygen or low birth weight or lack of essential fatty acids are responsible for it.
5) Mothers smoking during pregnancy period can play a vital role in making the child suffer from ADHD.
6) Some other causes include unbalanced and lack of nutritious diet, poor parenting and hormonal imbalance.


The above given causes are simply presumptions made by medical researchers. However the exact cause of ADHD which can be pin-pointed still remains a mystery. Thus the researches continue for finding out the exact cause and treatment of ADHD.
