The stress hormone and neurotransmitter norepinephrine is a naturally occurring molecule in the body (a substance that sends signals between nerve cells).
When the brain detects a stressful event, it is released into the bloodstream as a stress hormone.
Norepinephrine impacts how the brain pays attention and responds to events as part of the body's stress response. It can also do the following functions:
Boost your heart rate
The release of glucose (sugar) into the blood is triggered.
Muscle blood flow should be increased.
Norepinephrine is a neurotransmitter in the central nervous system that improves alertness and arousal while also speeding reaction time.
The hormone norepinephrine has been linked to a person's mood and ability to concentrate.
Attention deficit hyperactivity disorder (ADHD), depression, and hypotension can all be caused by low norepinephrine levels (very low blood pressure).
ADHD and norepinephrine
Norepinephrine and another neurotransmitter, dopamine, assist people in paying attention and focusing during their daily activities.
Low amounts of these substances in the brain can make it difficult to focus, resulting in ADHD symptoms.
ADHD can damage parts of the brain that help you solve issues, plan ahead, interpret others' behaviors, and control urges, according to the American Academy of Child and Adolescent Psychology.
The following drugs can help you focus by increasing norepinephrine and dopamine levels in your body:
Concerta or Ritalin? (methylphenidate)
Dexedrine is a stimulant (dextroamphetamine)
Adderall is a stimulant (amphetamine and dextroamphetamine)
Strattera (atomoxetine), another ADHD medication, only elevates norepinephrine levels, not dopamine.
