The main features of attention
deficit hyperactivity disorder are inattention, hyperactive and impulsive. No
one knows exactly what causes ADHD. It sometimes runs in families, so genetics
maybe a factor. They may also be environmental factors. A complete evaluation
by a trained professional is the only way to know for sure if the child has
ADHD or not.

Three main things that cause ADHD
are the genetic, biological and chemical. 90% of people with ADHD inherit from their parents. One interesting
clue to a genetic component of ADHD is looking at families. For example, children
with a sibling that has been diagnosed with ADHD are more likely to develop it
themselves. Furthermore, if those siblings are identical twins, meaning they
have the same DNA, their chances of developing ADHD is considerably higher.
Having identical DNA does not mean that the twin is definitely going to develop
ADHD. However, which again suggest that both genetic factors and environmental
factors play a part.

Besides
that, research has diagnosed some of possible variations in the brains of
people with ADHD compared to those who do not have the condition, despite the
fact that the exact significance of these is not clear. As an example, studies
involving brain scans have suggested that certain areas of the brain may be
smaller in people with ADHD, whereas other areas can be larger. Research has
also proven that the brain may take an average of two to three years longer to
mature in children with ADHD, as compared to children who don’t have the
condition. Other researches have suggested that human beings with ADHD might
also have an imbalance within the stage of neurotransmitters in the brain, or
that these chemicals may not work properly.

Various
other causes have also been suggested as playing a role in the development
of ADHD, including being born prematurely (before the 37th week of
pregnancy) , having a low birth weight, brain damage either in the womb or in
the first few years of life, drinking alcohol, smoking or misusing drugs while
pregnant.

However, the evidence
for many of these factors is inconclusive, and more research is needed to
determine if they contribute to ADHD.Treatment for
attention deficit hyperactivity disorder (ADHD) can help relieve the symptoms
and make the condition much less of a problem in day-to-day life. Treatment for
ADHD can be tricky, since symptoms may vary from patient to patient, although
most often involves both behavioral psychotherapy and medication. ADHD can be treated using medication or therapy, but a
combination of both is often the best. A specialist, such as a
pediatrician or psychiatrist, usually arranges treatment although the condition
may be monitored by your GP. 

There are five sorts of prescription for the treatment of
ADHD, which is methylphenidate, dexamfetamine, lisdexamfetamine, atomoxetine,
guanfacine. These medications
are not a permanent cure for ADHD, but may help someone with the condition
concentrate better, not be too impulsive, feel calmer and practice new skills.

On the other hand, behavioral psychotherapy is often targeted
at children, and focuses on teaching the child better time management and
organizational skills. For example, having structured routines that they can
follow and then giving rewards when they stick to the routines. Also, involving
both parents and teachers are important, and both behavioral parents training
and behavioral classroom management have been shown to be helpful for children
with ADHD.

As well as taking medication, different therapies also can be
useful in treating ADHD in children, teenagers and adults. Treatment is
likewise powerful in treating extra issues, for example, such as conduct or
anxiety disorders, which may appear with ADHD. Example of therapy is Psycho education, Behavior therapy, Parent training, education
programmes, and Social skills training.

Besides, there are other ways of treating ADHD that some
people with the condition find helpful, such as diet and taking supplements.
However, there is no strong evidence that these will work, and they should
not be attempted without medical advice.
