The Severity of Your Anxiety. Before learning what it is you're experiencing you need to note your own anxiety severity. I have developed an anxiety test that is a good place to start, since it will provide you with a severity graph along with treatment recommendations.
Neuroactive drugs that affect the brain are known to use the removal mechanisms to their advantage. The dopamine system, noradrenaline system, serotonin system, and cholinergic system are the major neurotransmitter systems in the brain. Serotonin and norepinephrine are the main chemicals responsible for depression.
Normally, there are brain cells (neurons) in the human brain that produce dopamine. These neurons concentrate in a particular area of the brain, called the substantia nigra. Dopamine is a chemical that relays messages between the substantia nigra and other parts of the brain to control movements of the human body.his process of impairment of brain cells is called neurodegeneration. The current theory (so-called Braak's hypothesis) is that the earliest signs of Parkinson's are found in the enteric nervous system, the medulla and in particular, the olfactory bulb, which controls your sense of smell.
