Neurotransmitter
Chemical messengers in the brain that transmit signals between neurons. ADHD is associated with imbalances in neurotransmitters like dopamine and norepinephrine.
Overview
Neurotransmitters are chemical messengers that allow communication between brain cells. ADHD is associated with differences in neurotransmitter function, particularly dopamine and norepinephrine.
Detailed Description
Neurotransmitters play crucial roles in brain function. In ADHD, research shows differences in dopamine and norepinephrine systems. Dopamine is involved in motivation, reward, attention, and movement. Norepinephrine affects attention, arousal, and mood. These neurotransmitter differences help explain why stimulant medications (which increase dopamine and norepinephrine availability) are effective for ADHD. However, ADHD is more complex than simple neurotransmitter deficits - it involves differences in brain structure, connectivity, and function as well.
How This Relates to ADHD
Understanding neurotransmitter function helps explain how ADHD medications work and why certain interventions are effective. It also helps reduce stigma by emphasizing the biological basis of ADHD.
Treatment and Management
Stimulant medications work by affecting neurotransmitter systems. Lifestyle factors like exercise, sleep, and nutrition also influence neurotransmitter function.
