Understanding ADHD

ADHDDo you have trouble completing tasks? Is it a struggle for you to sit still? Have you acted on impulse once too often? These are the main symptoms of attention deficit hyperactivity disorder (ADHD).

ADHD is fairly prevalent. According to the CDC, more American parents began reporting a diagnosis of ADHD for their children over the past few years.1 The CDC says these cases increased by 22% between 2003 and 2007.

Statistics don’t do this disorder any justice, though. ADHD is debilitating. For children, it can make it difficult to focus and behave in school. Their grades may suffer as a result.

ADHD starts during childhood but can continue into adulthood. And scientists have noted that adults with this disorder can have trouble keeping jobs and relationships.2

But there’s good news. Scientists recently made an important discovery. Last year, the science journal, UAB Divulga, reported that researchers had linked ADHD to abnormalities in the reward circuitry of the brain.3

The journal says this reward system is located in a part of the brain called the ventral striatum, which contains a collection of nerve cells known as the nucleus accumbens. Why is all this important? Well, McGill University notes that the nucleus accumbens uses the neurotransmitter, dopamine, during the reward process, and dopamine can make you feel good.4

A few years ago, the newspaper, Psychiatric News, said that ADHD may be caused by a dopamine deficiency.5 The newspaper cited a study showing that a drug used to treat ADHD also increased dopamine levels.

One study found that the herb, Centella asiatica (Gotu kola), might regulate several neurotransmitters, including dopamine.6

“It is very striking that Centella asiatica improves not only the cognitive performance but also the mood,” the study says. “The high dose of Centella asiatica could increase calmness and alertness after 1 and 2 months of treatment.” That means that people who take this herb might think clearly and feel good.

Overcoming the challenges of ADHD involves improving your thought process and remaining calm.
