An adrenergic storm is a sudden and dramatic increase in serum levels of the catecholamines adrenaline and noradrenaline (also known as epinephrine and norepinephrine respectively), with a less significant increase in dopamine transmission.
The general function of norepinephrine is to mobilize the brain and body for action. Norepinephrine release is lowest during sleep, rises during wakefulness, and reaches much higher levels during situations of stress or danger, in the so-called fight-or-flight response. In the brain, norepinephrine increases arousal and alertness, promotes ...
On the other hand, other medications that increase dopamine levels have also been found to improve anxiety. [42] Many physical symptoms of anxiety, such as rapid heart rate and hand tremors, are regulated by norepinephrine. Drugs that counteract norepinephrine's effect may be effective in reducing the physical symptoms of a panic attack. [42]

Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire ...
Additionally, noradrenergic CNS hyperactivity may play a role as CNS norepinephrine concentrations are increased in SS and levels appear to correlate with the clinical outcome. Other neurotransmitters may also play a role; NMDA receptor antagonists and γ-aminobutyric acid have been suggested as affecting the development of the syndrome. [ 6 ]
Elevation of norepinephrine levels can sometimes cause anxiety, mildly elevated pulse, and elevated blood pressure. However, norepinephrine-selective antidepressants, such as reboxetine and desipramine, have successfully treated anxiety disorders. [70] People at risk for hypertension and heart disease should monitor their blood pressure.
