Irreversible MAOIs are potentially more dangerous, because the body takes about two weeks to regenerate MAO enzymes to functional levels. [18] Two subtypes of MAO exist: MAO-A and MAO-B; this is relevant to adrenergic storms, as there are significant differences between the two types, such as their differential expression throughout the body ...
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 ...
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 ]
Serotonin syndrome is a potentially life-threatening drug reaction that causes the body to have too much serotonin. It can be caused by certain drug interactions, as well as drinking alcohol while ...
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]
SSRIs increase the extracellular level of the neurotransmitter serotonin by limiting its reabsorption (reuptake) into the presynaptic cell. [2] They have varying degrees of selectivity for the other monoamine transporters , with pure SSRIs having strong affinity for the serotonin transporter and only weak affinity for the norepinephrine and ...

In the brain, serotonin is a neurotransmitter and regulates arousal, behavior, sleep, and mood, among other things. [9] During prolonged exercise where central nervous system fatigue is present, serotonin levels in the brain are higher than normal physiological conditions; these higher levels can increase perceptions of effort and peripheral muscle fatigue.
