About depression and neurotransmitter?
Neurotransmitters are generally referred to as the actual chemicals responsible for our human brain activity, for instance when we’re joyful, neurotransmitters like dopamine, serotonin, oxytocin and noradrenalin are released by our brain. With those neurotransmitters released, certain circuits in the brain will then be activated to make us feel delighted.
There are changes continuously inside the neurotransmitter activities, depending on the present situations and also the surroundings we are in. For example, whenever we happened to capture a glimpse of a nice-looking stranger starring at us, certain neurons in our brain will release dopamine to create an activity of what is known typically as the brain’s “reward circuit”, that will ends up with us becoming positive and excited. The flexibilities within our emotions because of all these changes means that our emotions are normally in line with the demands of the moment.
Each time a person is in a depressed feeling, this dynamic chemical systems runs awry. The neurotransmitters failed to switch on in the brain cells which were supposed to react positively but instead getting unresponsive to the outside stimulation, ending in the stranger passing by without having being noticed.
Some brains may experience this kind of deadening in comparison with others, due to their actual physical structure. The human brain is composed of interactive “modules” – areas which are tasked with various characteristics. Areas that are mainly accountable for the feeling of pleasing emotions can be found within the front, left-hand side of the human brain. Brain modules are just like muscles in that the more they are used the larger they become.
Basically, whenever a person who has “worked out” that section of their brain all their life by having a joyful earlier childhood days, they will have a lot more “happy” grey matter to activate comparing to people who have been experiencing sadness for the most part of their lives. Due to the fact that brain cells will also die off if they are not put to good use, an individual can lose some abilities to be able to feel happy again in the future if previously they have experienced a long moment of intense despair during their childhood years. A depressive disorder cannot treat on its own and is particularly the main reason why it shouldn’t be kept alone to accomplish that. People suffering and don’t getting an early medication tend to experience a relapse than others who seek early treatment.
Depression: Norepinephrine Neurotransmitter
The response to a situation on whether to “fight or flight” is often dependant on the neurotransmitter known as norepinephrine. This neurotransmitter can create a sense of overwhelming fear and panic as it is has direct connections to physical reactions. The effects of norepinephrine neurotransmitter is similar to adrenaline. The brain levels of norepinephrine is directly related to depression and anxiety as it is tasked to manage the balancing between depression and agitation.
Depression, lack of alertness and poor memory are due to a low levels of norepinephrine in the brain. Norepinephrine is apparently the neurotransmitter for “arousal” and as a consequence, lower-than-normal amounts of this specific neurotransmitter develop below-average levels of interest as well as arousal, an indicator evident in many psychiatric types of conditions such as depressive disorders and ADHD. It is due to this that prescribed medicines intended for depression and ADHD usually focus on both norepinephrine and dopamine so that they can restore both back to the normal level.
Neurotransmitters for Anxiety and Depression
GABA (gamma-aminobutyric acid)
GABA neurotransmitter possesses a chemical influence on the central nervous system as it decelerates transmission of nerve signals and relaxes muscles
Epinephrine neurotransmitter raises blood pressure and heart rate.
Dopamine neurotransmitter is common due to its connection to feelings associated with ‘pleasures’ or ‘desire’, but will also be linked to memory, attention and body movements.
Serotonin neurotransmitter is associated with mood and emotion, learning, behavior, anxiety, sleep, sexuality, appetite and others.
Norepinephrine neurotransmitter is quite the same as epinephrine as it raises blood pressure, blood sugar levels and heart rate.
