![]() The diagnostic system of psychiatric disorders is relatively young, having been adopted back in 1980. So it’s easy to see why people get confused.īefore we talk about the differences, it’s worth it to take a brief historical look at attention deficit disorder to get an idea of how the term came about. Your lifestyle will determine your future.When searching for information on mental health issues, you’ll find attention deficit disorder (ADD) and attention deficit hyperactivity disorder (ADHD) lumped together.

Dysfunction in the area is therefore associated with a variety of ADHD symptoms like inattention, impulsivity, and/or hyperactivity.Ĭenters for Disease Control and Prevention. While it sounds simple, your brain has to filter through a lot of information. Reticular activating system (RAS): The RAS is a network of neurons in the brain stem that are involved in filtering information or organizing what’s important and what's not.Resting-state MRIs (magnetic resonance imaging scans) suggest people with ADHD may actually have an increased level of functional connectivity in certain brain regions than those without ADHD. Dysfunction doesn’t also mean deficient, though. Dysfunctional information processing has been shown in the circuit areas of people with ADHD. It’s linked to motion planning, which is characterized as knowing what steps to take and in what order. It receives information from other brain areas and relays the messages back and forth from the motor center. Basal ganglia: The basal ganglia is a group of structures associated with processing information.One 2017 study demonstrated that people with ADHD have dysfunction in the limbic system. Examples include having a hard time being quiet or controlling emotions. Differences in this area are associated with difficulties in self-regulating. Limbic system: Deep within the brain, the limbic system is responsible for emotional regulation.Brain structure and function differences in this region are associated with difficulties in developing and displaying executive functioning skills. Executive functioning is associated with organizing, planning, and maintaining attention. Prefrontal cortex and frontal cortex: Located at the front of the brain, the prefrontal and frontal cortex are responsible for high-level executive functioning.
