THE PHYSIOLOGICAL CHANGES THAT PRODUCE THE SYMPTOMS
By depression there's a decreased amount of neurotransmitters in parts of the central system nervous, mainly deficiency of serotonin, but also to some extent of acetylcholine, dopamine or (GBA), 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 two nerve cells.
The serotonin and a noradrenaline cause nerve cells to send impulses along to other nerve cells, and thus increases the activity within the brain
Deficiency of these substances causes slowness in parts of the brain, which again causes the depressive symptoms.
The role of GBA is that of the other, namely to hamper some nerve impulses, mainly those causing an anxiety and the panic response. A Lack of GBA causes higher anxiety and an easier, a panic response. Yet, A lack of these transmitters also seems to cause depressive symptoms. This is often because a too high activity in some brain processes may hamper other processes
There are many causes and subtypes of depression, with the different physiological mechanisms involved.
TYPES OF DEPRESSION
Depression are often divided into subtypes according to exhibited symptoms
1. Mono-polar depression and dysthymia disorder By mono-polar depression, there are pure depressive symptoms. Mild cases of mono-polar disorder that don't affect someone's ability to figures and to participate in social activities are often called
2.dysthymia disorder.
3. manic depression (manic-depressive disease) and cyclothymic In these conditions there are periods with symptoms of depression – the depressive phase, alternating with periods of elevated mood levels with increased mental and physical activity – the manic phase. Within the manic phase, the affected persons also sleep poorly and has concentration difficulties. A light sort of this disease is named cyclothymic.
3. Manic disorder
This condition is characterized by abnormally elevated a mood, by an unrealistic optimism, by lack of sleep and by hyperactive behavior. Many psychiatrists think that this disorder is just an equivalent disease as manic depression, where the depressive face has not yet occurred.
4. Depression with mainly physical symptoms
Sometimes the physical symptoms of depression are alone or dominant, as for an example: Digestive problems, constipation, difficulties with an urination, the slow response to sensorial stimuli is slow physical reactions. CAUSES OF DEPRESSION
Two or more factors can have an impact simultaneously to cause depression. Depression is often an independent disease, or a neighborhood of another disease.
Depression is additionally divided into different subtypes, consistent with cause.
1. Reactive depression
This disease is just a result from psychological stress, the physical struggle or mental straining without the right rest or stay over an extended period of time. The straining will simply wear out the system nervous or deplete the organism from the nutrient necessary for the system nervous to figure properly.
2. Endogenous depression
When there has not been any period of stress, straining or lack of the remainder which will explain the condition, the condition is usually called depressive disorder. The Inheritance is assumed to be a neighborhood of the cause.
3. Depression by physical disease
Depression or depressive symptoms could even be a logo of physical disease. This is perhaps the foremost common an explanation for To Generally There are three categories of the diseases that give depression:
Diseases often related to depression are: heart condition, Parkinson’s disease, stroke, hypertension or Cushing’s syndrome.
Mononucleosis and flu may trigger depression that continues after the infection has been gone.
By lack of thyroid hormones, hypothyroidism, the metabolism within the whole body is bogged down, including the assembly of neurotransmitters within the brain. Therefore, depression is a crucial symptom of hypothyroidism.
4. Depressive symptoms as the consequence of unsound lifestyle
A general unsound lifestyle with too less exercise, an excessive amount of stimulants like alcohol, coffee or tea, too less of important nutrient and an excessive amount of sugar and fat may be given the depressive symptoms, as well as physical problems.

The Women will an often have a period of depression after the pregnancy and birth of the baby Pregnancy and birth is physically and mentally exhausting, and should drain the body for nutrient. This successively can cause depressive symptoms.
6. Seasonal affective disorder
Depression can occur in cold and dark periods of the year and get away in warm and lightweight periods. Light stimulates brain activity, and lack of sunshine may be a causative factor.
TREATMENT OF DEPRESSION
Serious and prolonged depression is usually treated with anti-depressive medication. Medicines used against depression generally increase the extent of neurotransmitters like serotonin within the central system nervous, or they mimic the neurotransmitters.
The medications mostly used today increase of the serotonin concentration by the decreasing the removal of serotonin from the space around nerve cells. Examples of this medication types are: Fluoxetine (Prozac), fluoxetine, (Lox), duloxetine (Pail), Escitalopram, (leaps, Celina), sertraline (Zoloft).
By manic depression within the manic face, heavy tranquilizers (neuroleptic) are wont to stop the manic symptoms. By manic depression, lithium salts are sometimes wont to stabilize the condition, and stop new outbreak of depressive or manic faces.
Psychotherapy is usually employed by the depression, usually together with medication.
Sometimes serious depression is treated by applying electric shock through the top, electroshock. The shock induces epileptic eruption of nerve signals through the brain, and this provides cramps throughout the body. The cramps are the alleviated and stopped by the applying anesthesia before the electroshock. This form of treatment is controversial, since it can cause amnesia and is suspected of causing brain damage. The possibility of the brain damage is however denied by the most psychiatrists.
