Dopamine, epinephrine (adrenaline), and norepinephrine are the main catecholamines. Cross-reactive antibodies created in response to these pathogenic microbes attack the dopamine receptors in the basal ganglia of the brain, causing a fluctuation in dopamine, which results in OCD, tics and other neuropsychiatric symptoms. Low dopamine affects the ability to focus and think, while high dopamine causes an overload on the brainâs ability to process information. © 1996-2021 Everyday Health, Inc. This book focuses on hormones, and on how they are produced in very diverse regions of the body in humans and animals.
