Central Nervous System
The part of the nervous system consisting of the brain and spinal cord. ADHD is believed to involve differences in how the central nervous system regulates attention and activity.
Overview
The central nervous system (CNS) consists of the brain and spinal cord and is responsible for processing information and coordinating body functions. ADHD involves differences in how the CNS regulates attention, impulse control, and activity levels.
Detailed Description
Research shows that ADHD is associated with structural and functional differences in the central nervous system, particularly in areas responsible for executive functions, attention regulation, and impulse control. These differences involve neurotransmitter systems (especially dopamine and norepinephrine), brain structure (particularly the prefrontal cortex), and neural connectivity. These neurobiological differences are why ADHD is considered a neurodevelopmental disorder rather than simply a behavioral issue.
How This Relates to ADHD
Understanding ADHD as a CNS condition helps explain why symptoms persist across situations and why medication that affects neurotransmitter systems can be effective. It also helps reduce stigma by framing ADHD as a biological condition rather than a character flaw.
Treatment and Management
Treatments that affect the CNS, such as stimulant medications, work by improving neurotransmitter function. Non-pharmacological approaches like neurofeedback also target CNS function.
