Catecholamines are hormones that the brain, nerve tissues, and adrenal glands produce. The body releases catecholamines in response to emotional or physical stress. Catecholamines are responsible for the body’s “fight-or-flight” response. Dopamine, adrenaline, and noradrenaline are all catecholamines. Unusually high or low levels of individual catecholamines can cause medical issues. High or low levels of multiple catecholamines can indicate a serious underlying medical issue. This article outlines how catecholamines function and what high or low levels may indicate about a person’s health. It also discusses some ways in which a doctor may test a person’s catecholamine levels. Share on Pinterest Dopamine, adrenaline, and noradrenaline are the main types of catecholamine. Catecholamines are hormones that also function as The main types of catecholamine are dopamine, adrenaline, and noradrenaline. These hormones function in the following ways: Dopamine This neurotransmitter sends signals throughout the nervous system. It helps regulate the following: • movement • emotions • memory • the brain’s reward mechanism Adrenaline, or epinephrine This neurotransmitter is Noradrenaline, or norepinephrine This neurotransmitter Catecholamine levels that are too low or too high can sometimes indicate an underlying health issue. The main reason a doctor will test a person’s catecholamine levels is to check for the presence of certain tumors, such as a neuroendocrine tumor or a neuroblasto...

Did you know there are billions of neurons—and trillions of synapses—in your amazing brain? 1 ^1 1 start superscript, 1, end superscript (No wonder you can learn anything, including neurobiology!) Most of your synapses are chemical synapses, meaning that information is carried by chemical messengers from one neuron to the next. There are many different kinds of neurotransmitters, and new ones are still being discovered! Over the years, the very idea of what makes something a neurotransmitter has changed and broadened. Because the definition has expanded, some recently discovered neurotransmitters may be viewed as "nontraditional” or “unconventional” (relative to older definitions). The chemical messengers that act as conventional neurotransmitters share certain basic features. They are stored in synaptic vesicles, get released when Ca 2 + \text Ca 2 + start text, C, a, end text, start superscript, 2, plus, end superscript enters the axon terminal in response to an action potential, and act by binding to receptors on the membrane of the postsynaptic cell. The neuropeptides are each made up of three or more amino acids and are larger than the small molecule transmitters. There are a great many different neuropeptides. Some of them include the endorphins and enkephalins, which inhibit pain; Substance P, which carries pain signals; and Neuropeptide Y, which stimulates eating and may act to prevent seizures. How can that be the case? As it turns out, there isn’t just one type o...

A dopamine detox entails fasting from dopamine producing activities, or “pleasures,” for a certain amount of time with the hope of decreasing reward sensitivity. However, there is no scientific evidence to support this method. Those who attempt a dopamine detox aim to detach themselves from everyday stimuli, such as social media, sugar, or shopping. They are replaced in favor of less impulsive habits and lifestyle choices. The fast can last for a few hours or several days. It is very important to note that a dopamine detox is not a scientifically researched approach. Evidence of any benefits is anecdotal, and most benefits come from refraining from potentially addictive activities. However, they are not related to actually detoxing from dopamine. The entire concept of a “dopamine detox” is scientifically incorrect, and reduces the brain to a very simplistic level. It is, in fact, far more complex that this “dopamine detox” trend suggests. This article will explore dopamine detoxes in further detail, including potential risks, and even some incidental benefits. Share on Pinterest Frederike Wunsch/EyeEm/Getty Images Dr. Cameron Sepah is the creator of the The general concept behind Dr. Sepah’s “detox” is for people to let themselves feel lonely or bored, or to try simpler activities instead of reaching for quick “hits” of dopamine. Ideally, people will start to notice how certain stimuli might distract them. Dr. Sepah identifies six compulsive behaviors as targets of the dop...
