Definitions of Dopamine, Norepinephrine, Epinephrine

Hormones to stress response which plays a"big part" with Teenagers with Dysautonomia. Here are the definitions. In my next blogs I will write them all more in depth. It is very important to know each one of these in the connection with Dysautonomia and there is allot to write about all 3.

Dopamine is a neurotransmitter which is produced by the brains of many organisms, including humans. Like many neurotransmitters, dopamine has several different functions. It plays a critical role in the function of the central nervous system, and it is also linked with the brain's complex system of motivation and reward. Altered levels of dopamine in the brain can cause a range of symptoms and problems, ranging from Parkinson's disease to Attention Deficit Disorder (ADD).

Norepinephrine is a type of neurotransmitter, which is a chemical responsible for moving nerve impulses between neurons. It is found in both the central and sympathetic nervous systems, and it is made by the adrenal gland. Besides acting as a neurotransmitter, norepinephrine also acts as a stress hormone. It has a role to play in a person’s fight-or-flight response, working in conjunction with epinephrine. In this role, it increases a person’s heart rate and blood flow to the muscles; it also stimulates the release of blood sugar and is often compared to adrenaline.

Epinephrine is a hormone that is chemically identical to the adrenaline produced by the body, and the names of the two are often used interchangeably to some extent. When produced naturally by the body, it helps us respond effectively to short-term stress. Epinephrine is also used as a drug to treat cardiac arrest, asthma, and allergic reactions, especially those which could be fatal if left untreated. The first time that epinephrine was produced artificially was in 1895 by a physiologist from Poland, named Napoleon Cybulski.

Dysautonomia and Smoking horrible combo for ANS System

It's been a long while since I have put up a blog. Like I said before in my other blogs that, it does take some time to write about it because I too go through it and, so does my son. I am able to share our experiences with Dysautonomia and, help out others who need the help and need the education on what happens to someone with, Dysautonomia. I also get my knowledge through educated doctor's from Europe who know this disease, very well. I have also read up on allot of other people who have Dysautonomia and read their stories on, their Blogs. To you all, my heart is with you and, if I can shed some light on you in some way, I will do my best. I know some are going to write a Book. Much blessing  to you as well on helping those understand about their disease that is very frightening when, most doctor's here in America have not researched it or learned it in,  medical school. My primary care doctor is one person who is honest and up front and did say that, he never learned ...

Piracetam (Nootropil) used for Dysautonomia in other countries

Well, I did say in my past blogs that I will find the medication that some from other countries use for, "Dysautonomia". I am not sure if it is the cure but,I am learning from the Doctor who is teaching me about Dysautonomia that it works and, from other resources in, other countries. I also have relatives in Europe so, I had an Aunt do some research for me recently and, speak to their medical field in their area. According to her, "Nootropil" is what they use for "Dysautonomia" and that you need a prescription for it. After hearing that I did, more research. I searched the internet and found Nootropil here in the, USA. We call it "Piracetam-Nootropil". When I looked up what we used it for I was very surprised to what, I read. It was not used for Dysautonomia but, for other things and other medical issues. We call it the anti-aging "Brain Drug". I read an ad that said: "Wake up your brain! - With Piracetam (Nootropil)" ...
