Attention deficit hyperactivity disorder (ADHD or ADD) is a brain illness with a variety of possible causes, yet doctors are still unable to specify which one is responsible for the symptoms of ADHD. Researchers believe that ADHD is linked to a gene involved in the production of dopamine, a neurotransmitter that regulates the brain's capacity to sustain regular and consistent attention. However, today's ADHD myths and misperceptions significantly outnumber conclusive studies.
ADHD is not caused by poor parenting, excessive sugar consumption, or playing too many video games. It's a biological condition that affects the brain. Many changes in the brains of people with ADHD have been discovered through brain imaging studies and other research. According to other studies, a child with ADHD is four times more likely to have a family with the disorder.
According to the data, ADHD is a genetic condition that is passed down from parent to child. At least some families appear to have a history of ADHD. At least one-third of all fathers who had ADHD as a child have children who have the disorder as well. Furthermore, the ADHD feature is shared by the majority of identical twins.
Researchers in the United States and Europe are currently attempting to understand which genes, in particular, render a person susceptible to ADHD. Scientists are looking into a variety of genes that could have a role in the development of ADHD, particularly those linked to the neurotransmitter dopamine. Because ADHD is such a complex illness, they believe it is likely to involve at least two genes.
On the genetic side of ADHD, there's still a lot of study to be done. The finding of genes linked to ADHD may make it easier to diagnose the disorder. It may also make it feasible to develop more effective treatments for patients who suffer from a variety of ADHD sympto
