All of the medications that have been mentioned, increase levels of Dopamine and Nor-Adrenaline.
With the main difference between the med's, are their 'side effects'.
But have the common effect on Dopamine (Do) and Nor-Adrenaline (NA) levels.
Though their main action, is as 'Inhibitors'.
So that they prevent enzymes, from taking Do and NA apart, and removing them.
Storing them away, for re-use.
But what we are talking about, are our Nerve Cells or Neurons.
Which use Do and NA to send signals along a pathway of Nerve Cells/ Neurons.
Where Do and NA sit in gaps between the Neurons, called Synaptic Clefts.
Each Neuron, has a range of different Receptors, that molecules such as Do and NA, attach to.
Which will have an 'effect', as long as they are in place.
For example, Nor-Adrenaline, is the Normal Adrenaline that circulates in our 'system'.
When NA is attached to a Neuron, it adds motivation to an activity.
Which keeps our attention focused on an activity.
So that if you look at the 'Pharmacodynamics', of all the previously mentioned Medications?
You will see, that they all 'inhibit enzymes from removing NA from the Neuron clefts.
Which will have the effect of keeping one focused on an activity.
But then their is another important molecule, that Neurons use? Which is called Serotonin (SN).
Each of our Neurons, have 15 different Receptors for Serotonin.
So that it is used in different ways.
Though the primary use of Serotonin, is a 'Regulator of Signals'.
Which filters out the Signals, and enables us to focus on particular ones.
This plays an essential role, in regulating Impulses.
Their are a range of medications for this called: SSRI's.
Which Inhibit enzymes from removing Serotonin, from Neurons.
(The full name is: 'Selective Serotonin Reuptake Inhibitors'. Where this term 'Reuptake Inhibitors' is often used to describe the actions of Med's. But it simply means, that the Med stops enzymes from removing a molecule, such as Do, NA or Sn from Neurons.)
My concern, is that the focus of discussion, is about Medications and their side effects?
Where the real issue, is that having tried these different 'Dopamine and Nor-Adrenaline Inhibitors', without any significant benefit?
That perhaps Serotonin Inhibitors might be considered?
