One paragraph in this link is so important that I quoted it here: Neuroses may therefore very frequently produce secondary magnesium depletion. They require their own specific anti-neurotic treatment and not mere oral magnesium physiological supplementation, but both genuine forms of neurosis due to primary neural magnesium deficiency and magnesium depletion secondary to a neurosis may exist.

These two conditions may be concomitant and reinforce each other. In these stressful patients it may be difficult to establish the primacy of one or the other. In practice, physiological oral magnesium supplements may be added to psychiatric treatments, at least at the start. Stress intensifies release of two major classes of "stress hormones", the catecholamines and corticosteroids, which normally greatly increase survival of well animals when their lives are threatened.

Catecholamines are chemically similar small molecules derived from the amino acid tyrosine. The major catecholamines are dopamine, norepinephrine, and epinephrine old name: Dopamine is a neurotransmitter a chemical used to transmit impulses between nerve cells found mainly in the brain.

Norepinephrine is the primary neurotransmitter in the sympathetic nervous system controls the "fight or flight" reaction and is also found in the brain.

Epinephrine is not only a brain neurotransmitter, but also a major hormone in the body. Epinephrine is secreted from the adrenal medulla in response to low blood glucose, exercise, and various forms of acute stress in the latter case, the brain stimulates release of the hormone.

Epinephrine causes a breakdown of glycogen to glucose in liver and muscle, the release of fatty acids from adipose tissue, vasodilation of small arteries within muscle tissue, and increases the rate and strength of the heartbeat. All of the catecholamines are metabolized by their target tissues or by the liver to become inactive substances that appear in the urine: Consequently, a urine test for elevated catecholamines is both simple and available.

If you want to test your brain neurotransmitters, you can get them tested by using a neuroscience test kit supplied by local physicians.

Corticosteroids are group of natural and synthetic analogues of the hormones secreted by the hypothalamic-anterior pituitary-adrenocortical HPA axis, more commonly referred to as the pituitary gland.

These include glucocorticoids, which are anti-inflammatory agents with a large number of other functions; mineralocorticoids, which control salt and water balance primarily through action on the kidneys; and corticotropins, which control secretion of hormones by the pituitary gland.

They have been thoroughly researched and developed as drugs in the treatment of many diseases, but not including depression treatment. Corticosteroids are used to provide relief for inflamed areas of the body. They are extremely strong drugs. They lessen swelling, redness, itching, and allergic reactions.

They are often used as part of the treatment for a number of different diseases, such as severe allergies or skin problems, asthma, arthritis and certain cancers and leukemias.

They have many well-known side effects.

When magnesium deficiency exists, stress paradoxically increases risk of cardiovascular damage including hypertension, cerebrovascular and coronary constriction and occlusion, arrhythmias, sudden cardiac death SCDasthma, anxiety and depression.

Thus, stress, whether physical i. Magnesium deficiency intensifies adverse reactions to stress that can be life threatening. Such reactions are mediated by excess release of the stress hormones, catecholamines and corticosteroids, which are increased by low magnesium and high calcium levels, and which further lower tissue magnesium in a feed back fashion, and suppress testosterone production.

Testosterone production may or may not return upon replenishing magnesium. If it does not return, low testosterone can be an additional cause of depression, and testosterone creams, shots and pills are available.

The creams are definitely the least likely to produce side effects. Shots and pills of testosterone can result in weird side effects that stimulate dangerously high female sex hormone production in men, which requires a female sex hormone suppressant treatment such as daily tablets of Arimedex.

You can end up with more problems than before, thus they are prescription-only items. Genetic differences in magnesium utilization may account for differences in vulnerability to magnesium deficiency and differences in body responses to stress.

There are so many stressors in our active lives that adversely affect magnesium reserves; it is a miracle that we can live on our puny magnesium deficient diets without vastly more cardiac and psychiatric problems.

Magnesium is a required nutrient for people to handle stress in general and stress in neuropsychiatric disorders. Not getting sufficient dietary or supplemental magnesium during medical or depression treatment for stress related disorders such as anxiety and depression is bound to fail.

Sometimes stress depletion of magnesium is so intense that dietary sources are insufficient, and supplementation is required to avoid depression and many other neurological conditions. Measure your level of stress here. These effects and aggressive behavior are easily observed in the mouse model.Despite Tel Aviv being up today (this has been a very strong market this year) the spread between the broad Market ETFs and in particular svxy and their net asset values is just too wide in favor of the ETFs, but usually signals a pullback of one to three days, indicative .
