How do you know if norepinephrine is too high?
Signs of a high norepinephrine level include racing thoughts, anxiety, and high blood pressure.

What happens if you have too little norepinephrine?

What neurotransmitter do ADHD people lack?
People with ADHD have at least one defective gene, the DRD2 gene that makes it difficult for neurons to respond to dopamine, the neurotransmitter that is involved in feelings of pleasure and the regulation of attention.
How do you know if your low in norepinephrine?
