The Causes of Attention Deficit Hyperactivity Disorder

There are many causes of attention deficit hyperactivity disorder. They are brain structure, brain chemicals, nerve pathways, genetic factors, dietary factors, and environmental factors.

Brain Structure And Causes of Attention Deficit Hyperactivity Disorder

Studies using modern imaging methods show there is a variation in the size of some parts of the brain in kids with ADHD when related to kids who do not have ADHD. The regions showing difference are the caudate nucleus and globus pallidus, the prefrontal cortex, and the cerebellum.

Brain Chemicals

Irregular activity of some brain chemicals present in the prefrontal cortex may cause attention deficit hyperactivity disorder. The chemicals such as dopamine and norepinephrine are of very special concern. These chemicals are neurotransmitters, or chemical couriers, that impact both mental and emotional performance. They also have an important role in the “reward response.”

Nerve Pathways

Another region of concern is a network of nerves known as the basal-ganglia thalamocortical nerve tract. Irregularities along this neural path have been linked with causes of attention deficit hyperactivity disorder, Tourette syndrome, and obsessive-compulsive troubles, all of which share some indications.

Genetic Factors

Genetic elements may act as the most significant role in ADHD. The relations of attention deficit hyperactivity disorder children, both boys and girls have much greater level of ADHD, asocial, mood, anxiousness, and substance abuse troubles than the families of non-ADHD kids. A research described that most of the children with a diagnosing of ADHD dealt it with their twin.

About half of adults and most of children with a genetic immunity to thyroid hormone, necessary for normal brain growth, have ADHD. Individual who have this problem seem to have a more serious kind of ADHD. The thyroid trouble is not a usual cause of ADHD. Only people with a family background of thyroid illness are at danger.

Dietary Factors

Infant deficiency disease is a big risky attention deficit disorder symptom. Even if kids get adequate food later on, babies who suffer from poor nutrition may have behavior troubles, the most prevailing being attention-deficit trouble.
Lacks in Zinc and Essential Fatty Acids also cause attention deficit hyperactivity disorder. Various dietary elements have been studies in link with ADHD which also includes sensitivities to some food chemicals, lack of fatty acids (substances that cook up fats and oils) and zinc, and sensitive to sugar.

Environmental Factors

Studies recommend that antenatal vulnerability to alcohol, environmental lead, tobacco, and other poisonous substance may raise the danger for ADHD and behavioral troubles.
