[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 ...
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 ]
