By depression there’s a decreased amount of neurotransmitters in elements of the central nervous system, mainly deficiency of serotonin, but also to some extend of noradrenalin, acetylcholine, dopamine or gamma-amino-butyric acid (GABA), or the nerve cells don’t react properly by stimulation from neurotransmitters. A neurotransmitter may be a signal substance that transmits the nerve signal through the junctions between 2 nerve cells.
Serotonin and noradrenalin cause nerve cells to send impulses along to alternative nerve cells, and therefore increase the activity in the brain. Deficiency of those substances causes slowness in parts of the brain, which again causes the depressive symptoms.
The role of GABA is the other, particularly to abate some nerve impulses, mainly those inflicting anxiety and panic response. Lack of GABA causes higher anxiety and easier panic response. However, lack of this transmitter also looks to cause depressive symptoms. This is as a result of a too high activity in some brain processes could slow down alternative processes.
There are many causes and subtypes of depression with different physiological mechanisms involved.
TYPES OF DEPRESSION
Depression is typically divided into subtypes per exhibited symptoms.
1. Mono-polar depression and dysthymic disorder
By mono-polar depression there are pure depressive symptoms. Gentle cases of mono-polar disorder that don’t have an effect on a persons ability to work and to participate in social activities are typically called dysthymic disorder.
2. Bipolar disorder (manic-depressive disease) and cyclothymic disorder
In this condition there are periods with symptoms of depression – the depressive section, alternating with periods of elevated mood level with increased mental and physical activity – the manic phase. Within the manic part, the affected person also sleeps poorly and has concentration difficulties. A delicate form of this disease is called cyclothymic disorder.
3. Manic disorder

1. Reactive depression
This disease is merely a result from psychological stress, physical struggle or mental straining without proper rest or sleep over a long time period. The straining can merely wear out the nervous system or deplete the organism from nutrient necessary for the nervous system to figure properly.
2. Endogenous depression
When there has not been any amount of stress, straining or lack of rest that may explain the condition, the condition is usually known as endogenous depression. Inheritance is thought to be a part of the cause.
3. Depression by physical disease
Depression or depressive symptoms might be a proof of physical disease. This can be perhaps the foremost common reason behind depression. Usually there are 3 classes of diseases that offer depression:
Diseases typically related to depression are: Heart disease, Parkinson’s disease, stroke, hypertension or Cushing’s syndrome.
Mononucleosis or flu could trigger depression that continues after the infection has gone.
By lack of thyroid hormones, hypothyroidism, the metabolism in the entire body is slowed down, including the assembly of neurotransmitters within the brain. Therefore depression is a vital symptom of hypothyroidism.
4. Depressive symptoms as a consequence of unsound lifestyle

TREATMENT OF DEPRESSION
Serious or prolonged depression is often treated with anti-depressive medication. Medicines used against depression generally increase the amount of neurotransmitters like serotonin in the central nervous system, or they mimic the neurotransmitters.
The medications mostly used nowadays increase the serotonin concentration by decreasing the removal of serotonin from the area around nerve cells. Examples of this medication type are: Fluoxetine (Prozac), fluvoxamine (Luvox), paroxetine (Paxil), escitalopram (Lexapro, Celexa), sentraline (zoloft).
By bipolar disorder within the manic face, significant tranquilizers (neuroleptica) are used to stop the manic symptoms. By bipolar disorder, lithium salts are typically used to stabilize the condition, and stop new outbreak of depressive or manic faces.
Psychotherapy is generally employed by depression, sometimes in combination with medication.
Typically serious depression is treated by applying electrical shock through the top, electroconvulsive therapy. The shock induces epileptic eruption of nerve signals through the brain and this gives cramps throughout the body. The cramps are alleviated or stopped by applying anaesthesia before the electroshock. This type of treatment is controversial, since it can cause memory loss and is suspected of causing brain damage.
