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 ]
Pheochromocytoma is a rare neuroendocrine tumor that results in the release of too much epinephrine and norepinephrine, hormones that control heart rate, metabolism, and blood pressure. [14] AMPT was used in the 1960s for preoperative pharmacological control of catecholamine overexpression that causes hypertension and other arterial and cardiac ...
During a panic attack, the body's stress response is triggered which can cause the small vessels of the heart to tighten, leading to chest pain. The body's nervous system and rapid breathing during a panic attack can cause spasming of the arteries of the heart (also known as vasospasm). This can reduce blood flow to the heart, causing damage to ...
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 ...

Stress hormones can also induce a state of chronic inflammation, [8] which can damage the body's tissues and organs and increase the risk of chronic diseases, such as arthritis, diabetes, and cardiovascular disease. These effects can make the body more vulnerable to chronic infections, such as bacterial infections and autoimmune diseases, which ...
