![]() Dopamineĭopamine is more involved in brain functioning, while epinephrine and norepinephrine are both involved in activating the sympathetic nervous system in the fight-or-flight response to stressful situations. The individual functions of the catecholamines are all very important functions for children. Other times, too much catecholamines are released, and children over-respond in highly stressful situations. Sometimes not enough catecholamines are released, and children under-respond in highly stressful situations. ![]() Catecholamines and Neurodevelopmental DisordersĬhildren with autism, ADHD, Sensory Processing Disorder or those with chronic illnesses often have irregularies and/or irregular functioning of catecholamines. The three main catecholamines are dopamine, epinephrine (adrenaline) and norepinephrine, and all three have different functions. Catecholamines are then released into the blood stream usually when adrenocorticotropic hormone (ACTH) increases and cortisol levels are elevated. The adrenal glands create large amounts of catecholamines to prepare the body and brain to deal with extreme physical and emotional stress. In chemistry these hormones have a benzene ring with two OHs (hydroxides), hence the odd name.Ĭatecholamines are produced by the adrenal glands, which are located on top of the kidneys. Catecholamines are naturally occurring amines that function as hormones and neurotransmitters in the body.
