ADHD is a neurobiological condition that affects a persons ability to manage their own emotions, thoughts, and actions. The exact cause of ADHD is not fully understood, but it is believed to be a combination of factors. Here are some possible causes of ADHD in the brain:
-
Genetics: ADHD tends to run in families, and a child with ADHD has a 1 in 4 chance of having a parent with the condition. Other close family members, such as siblings, are also likely to have ADHD. Researchers have identified several genes that may contribute to the development of ADHD.
-
Brain anatomy and function: Studies have shown that there are differences in the brains of people with ADHD compared to those without the condition. For example, certain areas of the brain may be smaller in people with ADHD, whereas other areas may be larger. A lower level of activity in the parts of the brain that control attention and activity level may also be associated with ADHD. Neurotransmitters, which are chemicals that help transmit signals from one nerve cell to another, may also play a role in ADHD.
-
Groups at risk: Certain people are believed to be more at risk of ADHD, including those who were born prematurely or with a low birth weight, those with epilepsy, and those with brain damage that happened either in the womb or after a severe head injury. Prenatal exposures, such as alcohol or nicotine from smoking, may also increase the risk of developing ADHD.
In summary, ADHD is a complex condition that is likely caused by a combination of genetic, environmental, and neurological factors.
