Depression

Sunday, May 11th, 2008

The various kinds of schizophrenia are coupled with a lack of balance of dopamine (plenty) and serotonin (hardly controlled) in particular zones of the brain. Ultimately, the depressive disorders seem to be coupled with changed brain norepinephrine and serotonin systems. Both norepinephrine and serotonin neurochemicals are lower in people who are depressed. Please regard that I stated precisely, “coupled with” in place of, “caused by.” I made this differentiation because no one knows if low levels of neurochemicals in the brain lead to depression or if depression leads to low levels of neurochemicals in human brain.

We know in particular cure that changes in the levels of serotonin and norepinephrine can facilitate the signs of depression. Certain medicaments that influence both serotonin and norepinephrine neurochemical systems seem to perform even quicker and better. Other medicaments that cure depression chiefly influence the other neurochemical systems. The strongest cure for depression, electroconvulsive therapy, is definitely not peculiar to any certain neurotransmitter system. On the contrary, electroconvulsive therapy, by resulting in convulsion, makes a generalized brain activity that maybe produces enormous quantities of all of neurochemicals.

The chance of women to get depressed is twice as more in comparison with men. Nevertheless, the scientists have no explanation for this difference. Individual’s vulnerability to depression is also affected by psychological factors. Constant deprivation in childhood, physical or other forms of insult, mixture of particular individuality features all can augment the intensity and frequency of depressive disorders, without or with hereditary vulnerability.

At present the scientists are doing studies of influence of maternal-fetus strain on depression. It appears that maternal strain during pregnancy can augment the chance that the child will have a tendency to depression as an adult, especially if there is a genetic weakness. Scientists guess that the strain hormones circulating in mother can affect the growth of the fetus during pregnancy. This changed fetal brain growth happens in ways that predispose the child to the hazard of depression as an adult. Further studies are required to find out how this occurs. Besides, this situation displays the complicated cooperation between the genetic vulnerability and environmental strain, in this case, the strain of the mother on the fetus.

The reasons of depression

Friday, May 9th, 2008


 Some kinds of depression are common for certain families. This means that vulnerability to depression can be passed from generation to generation. That is particularly true with manic depression. The research was made of families in which members of each generation contract manic depression. The researchers discovered that those with ailment have a rather special genetic nature than those who do not fall ill. Nevertheless, the opposite is not true. That signifies that not everybody with genetic nature that results in vulnerability to manic depression has the ailment. Evidently, extra factors, maybe a stressful setting, are involved in its origin.Major depression also appears to occur in generation after generation in certain families, although not as heavily as in manic depression or bipolar II. Really, major depression can also occur in people who have no family depression history.

An outward event frequently appears to trigger a case of depression. Thus, a grave loss, hard relationship or chronic ailment, financial trouble or any other unpleasant shift in one’s life can initiate a depression. It’s quite common that a mixture of genetic, environmental and psychological causes is involved in the origin of a depressive disorder.

The human brain is complicated and charming like nothing else in the World. There are above hundred chemicals, known as neurochemicals or neurotransmitters, which circle in the brain. Nevertheless, most of our studies and knowledge has concentrated on four of these neurochemical systems: serotonin, dopamine, acetylcholine and norepinephrine. There’s a chance that in the new millennium these four neurochemicals will be considered as the twentieth century’s “blood, phlegm, black bile and yellow bile”.

Various neuropsychiatric aliments appear to be coupled with a plenty or a lack of some of these neurochemicals in particular parts of the brain. For instance, a shortage of dopamine at the base of the brain results in Parkinson’s disease. Lower concentration of acetylcholine levels in the brain appears to cause Alzheimer dementia. The addictive disorders are affected by the neurochemical dopamine. That means medicaments and alcohol effect by releasing dopamine in the brain. The dopamine produces a state known as euphoria. Recurring application of medicaments or alcohol, however, makes the dopamine system less sensitive, which signifies that the system gets accustomed to the medicaments and alcohols. Consequently, an individual needs more medicaments or alcohol to obtain the same sensation. Thus, the addicted individual takes more and more medicaments or alcohol to sense less and less high.

Depressive Disorder

Saturday, May 3rd, 2008

Depressive disorders have existed since the time when the manhood started writing history. Both Job and King David, we have read about from Bible, had this type of ailment. Hippocrate mentioned depression as melancholia or in other words “black bile”. Black bile in the medical physiology of that time was one of four main fluids that the man had. The rest three fluids include phlegm, blood and yellow bile. Depression has been written about in literature for rather long period. However, what do we imply nowadays when we speak about depressive disorder?
In the nineteenth century it was considered as the ancestral fragility of character. Freud, living in the first part of the twentieth century, associated the progress of depression with fault and conflict. The author and contemporary sufferer of depressive disorder guessed that the conflicts between him and his parents affected the growth of his depression.
Later, in the nineteen fifteenths and sixteenths, depression was separated into two kinds: neurotic and endogenic. Neurotic also known as reactive depression has a sharp environmental resulting factor. The examples, of this: the death of a spouse or loss of a job. Endogenic stands for the depression that arises from within the body (genetic lineage) or arises from nowhere.
In the late 80s the main emphasis was put on the depression’s effects on suffering people rather than on the source of depression. Namely, the specialists concentrated on symptoms and weakened functions that make up a depressive disorder.

Here are the common statements about depressive disorder that most specialists accept as true:
(1) A depressive disorder is a group of signs that indicate a sad mood transcending normal grief or sorrow.
(2) Depression signs are described by negative moods, behaviors and thoughts, as well as particular shifts in corporal functions. (for instance, abnormal sleeping, eating and diminished libido) The functional shifts of clinical depression are frequently referred to as neurovegetative symptoms. That stands for the nervous system shifts in the brain leading to a lot of physical shifts that bring a decreased participation and activity.
(3) Particular individuals with depressive disorder are seemed to have an ancestral vulnerability to this state
(4) Depressive disorders are an enormous nation health question. They frequently affect the productivity and absenteeism. They can augment the hazards for growth of coronary artery ailment, asthma, HIV and some other medical ailments.
(5) As a rule, depression is initially diagnosed in a primary health care environment, rather than in a mental health doctor’s room.
(6) Depression is frequently under-cured, despite of a sharp research proof and clinical guidelines about the therapy.
(7) For complete treatment from a depression disorder the cure with medicaments and/or psychotherapy as well as electroconvulsive therapy are a must.
