What Causes Attention Deficit Hyperactivity Disorder (ADHD)?

 

Attention deficity hyperactivity disorder (ADHD) is a neurobehavioral issue that affects many children worldwide. If untreated, ADHD may progress into adulthood and can cause learning difficulties and a poor quality of life. ADHD actually influences the manner in which a person’s brain processes information and leads to changes in behavior.

The exact reasons for this disorder are unknown. Yet some experts believe that genes, nutrition and the nervous system of the body all play a role during its development, as well as other factors. Here are some factors that affect the development of ADHD.

Genes     

There is evidence that genes can affect ADHD. Specialists have discovered that ADHD keeps running in families in twin and family studies. It’s been found to influence close relatives of individuals with ADHD. You and your siblings will probably have ADHD if your father or mother has it.

Nobody knows which of these genes have a greater impact on ADHD. Numerous studies have identified whether an association exists between ADHD and a gene known as DRD4. Initial research shows that this gene affects dopamine receptors in the brain. Yet, there may be more than one gene that can lead to ADHD. It is also noteworthy that ADHD has been diagnosed in people with no family history of this disorder.

Neurotoxins

Numerous scientists accept there might be an association between ADHD and certain neurotoxic compounds like lead and a few pesticides. Lead exposure in children leads to learning problems, inattention, hyperactivity, and impulsivity.

Nutrition

There is no solid proof that certain foods and additives may cause hyperactivity in children. Processed foods often contain artificial flavorings, colorings and preservatives but experts have not yet determined whether all these can lead to the development of ADHD or not.

Smoking and alcohol use during pregnancy

Maternal smoking is related to the development of ADHD in children later on in life. Children whose mothers took alcohol during pregnancy may also develop ADHD later in life according to a 2012 study.

Myths: What Doesn’t Cause ADHD?

Research has discovered no proof that ADHD is caused by:

  • Increased sugar intake
  • Watching TV
  • Video games
  • Poverty
  • Poor parenting practices

Actually, these factors can cause ADHD to worsen but there are very few studies that have shown that they can actually cause ADHD.
