Subtitle: ADHD in the Brain
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that affects behavior, emotions, and the ability to concentrate. It is usually diagnosed in childhood, but can continue into adulthood. While the exact cause of ADHD is not known, research suggests that it is caused by differences in certain brain structures and functions.
Neurotransmitters are chemicals that carry messages from one nerve cell to another. It is believed that in people with ADHD, the levels of certain neurotransmitters, such as dopamine and norepinephrine, are lower than in people without the disorder.
Brain Structure studies have shown that people with ADHD have differences in certain areas of the brain. The prefrontal cortex, which is responsible for problem solving, decision making, and impulse control, may be smaller in people with ADHD. Additionally, the brain's basal ganglia, which is involved in motor control, emotion, and motivation, may be larger.
Brain Function research has also shown that people with ADHD have differences in the way certain areas of the brain communicate with each other. For example, the prefrontal cortex and the basal ganglia may not communicate as efficiently as they do in people without the disorder. This can lead to difficulty controlling impulses and regulating emotions.
While the exact cause of ADHD is still unknown, research is ongoing to better understand the disorder and develop effective treatments. By understanding the differences in brain structure and function, doctors can provide more targeted and effective treatments for ADHD.
