Low mood level or sadness isoften the most prominent symptom. The common property of these symptoms is a decreasedactivity level in parts of the brain.THE SYMPTOMS OF DEPRESSIONDepression may give one or more of these symptoms:-Low mood level or sadness.-Lack of joy or interest in activities that were joyful before.-Pessimism.-Feel of guilt of something without any substantial reason to feel so.-Inferiority thoughts.-Irritability.-Slowness in the thought process.-Slowness in interpreting sensorial stimuli.-Slowness of digestion or other internal physical processes, and symptoms caused by thisslowness, for example inflated stomach, constipation or difficulties by urination.-Slow physical reactions.Depression can be a mild disease that only causes some annoyance in the daily life, but can alsoget very serious and make a person totally unable to work and unable to participate in social life.By depression of some severity, there is also a greater risk of suicide.Depression can occur in all age classes. In teenagers lack of interest in school work, withdrawalfrom social life and difficult mood can be signs of depression.THE PHYSIOLOGICAL CHANGES THAT PRODUCE THE SYMPTOMSBy depression there is a decreased amount of neurotransmitters in parts 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 do not react properly bystimulation from neurotransmitters. A neurotransmitter is a signal substance that transmits thenerve signal through the junctions between two nerve cells.Serotonin and noradrenalin cause nerve cells to send impulses along to other nerve cells, andthus increase the activity in the brain. Deficiency of these substances causes slowness in parts ofthe brain, and that again causes the depressive symptoms.The role of GABA is the opposite, namely to slow down some nerve impulses, mainly thosecausing anxiety and panic response. Lack of GABA causes higher anxiety and easier panicresponse. Yet, lack of this transmitter also seems to cause depressive symptoms. This is becausea too high activity in some brain processes may slow down other processes.There are many causes and subtypes of depression with different physiological mechanismsinvolved.TYPES OF DEPRESSIONDepression is often divided into subtypes according to exhibited symptoms.1. Mono-polar depression and dysthymic disorderBy mono-polar depression there are pure depressive symptoms. Mild cases of mono-polardisorder that do not affect a persons ability to work and to participate in social activities are oftencalled dysthymic disorder.2. Bipolar disorder (manic-depressive disease) and cyclothymic disorderIn this condition there are periods with symptoms of depression - the depressive phase, alternatingwith periods of elevated mood level with increased mental and physical activity - the manic phase.In the manic phase, the affected person also sleeps poorly and has concentration difficulties. Amild form of this disease is called cyclothymic disorder.3. Manic disorderThis condition is characterized by abnormally elevated mood, by unrealistic optimism, by lack ofsleep and by hyperactive behaviour. Many psychiatrists think that this disorder is simply the samedisease as bipolar disorder where the depressive face has not yet occurred.4. Depression with mainly physical symptomsSometimes the physical symptoms of depression are alone or dominant, as for example: Digestiveproblems, constipation, difficulties with urination, slow response to sensorial stimuli or slowphysical reactions.CAUSES OF DEPRESSION
Two or more factors can have an effect simultaneously to cause depression. Depression can bean independent disease, or a part of other disease. Depression is also divided into differentsubtypes according to cause.1. Reactive depressionThis disease is simply a result from psychological stress, physical struggle or mental strainingwithout proper rest or sleep over a long time period. The straining will simply wear out the nervoussystem or deplete the organism from nutrient necessary for the nervous system to work properly.2. Endogenous depressionWhen there has not been any period of stress, straining or lack of rest that can explain thecondition, the condition is often called endogenous depression. Inheritance is thought to be a partof the cause.3. Depression by physical diseaseDepression or depressive symptoms may be a symptom of physical disease. This is perhaps themost common cause of depression.Diseases often associated with depression are: Heart disease, Parkinsons disease, stroke,hypertension or Cushings syndrome.Mononucleosis or flu may trigger depression that continues after the infection has gone.By lack of thyroid hormones, hypothyroidism, the metabolism in the whole body is slowed down,including the production of neurotransmitters in the brain. Therefore depression is an importantsymptom of hypothyroidism.4. Depressive symptoms as a consequence of unsound lifestyleA general unsound lifestyle with too less exercise, too much of stimulants like alcohol, coffee ortea, too less of important nutrient and too much of sugar and fat may give depressive symptoms,as well as physical problems.5. Postnatal depressionWomen will often have a period of depression after pregnancy and berth of the baby Pregnancyand berth is physically and mentally exhausting, and may drain the body for nutrient. This in turncan cause depressive symptoms6. Seasonal affective disorderDepression can occur in cold and dark periods of the year and go away in warm and light periods.Light stimulates brain activity, and lack of light is a causative factor.TREATMENT OF DEPRESSION
Serious or prolonged depression is often treated with anti-depressive medication. Medicines usedagainst depression generally increase the level of neurotransmitters like serotonin in the centralnervous system, or they mimic the neurotransmitters.The medications mostly used today increase the serotonin concentration by decreasing theremoval of serotonin from the space around nerve cells. Examples of this medication type are:Fluoxetine (Prozac), fluvoxamine (Luvox), paroxetine (Paxil), escitalopram (Lexapro, Celexa),sentraline (zoloft).By bipolar disorder in the manic face, heavy tranquilizers (neuroleptica) are used to stop the manicsymptoms. By bipolar disorder, lithium salts are sometimes used to stabilize the condition, andprevent new outbreak of depressive or manic faces.Psychotherapy is sometimes used by depression, usually in combination with medication.Sometimes serious depression is treated by applying electric shock through the head,electroconvulsive therapy. The shock induces epileptic eruption of nerve signals through the brainand this gives cramps throughout the body. The cramps are alleviated or stopped by applyinganaesthesia before the electroshock. This form of treatment is controversial, since it can causememory loss and is suspected of causing brain damage. The possibility of brain damage ishowever denied by most psychiatrists.By seasonal depression, light therapy maybe useful.Adjustment of lifestyle should always be considered by depression or depressive symptoms.Lifestyle measures can sometimes be enough to cure depressive symptoms before a seriousdepression develop. Lifestyle adjustments can be:- To slow down a stressful life with too much work or activities.- Enough rest and sleep.- A good diet with enough of necessary nutrients.- Some physical exercise.- Meditation.- Supplement of vitamins, minerals, antioxidants, lecithin, amino acids and essential fatty acids.- Stimulants like coffee or tea may help against depressive feelings in moderate amount. However,if you are a heavy user of these stimulants, you should cut down on your consumption.There exist nutritional products in the marked to help against depressive symptoms. These containingredients that the brain uses as building blocks for neurotransmitters, for example amino acidsand lecithin. They also often contain vitamins and minerals that the brain uses as tools to produceneurotransmitters, especially vitamin B6.
Supplements may further contain herbal extracts that trigger higher brain activity much like anti-depressive medications, but may have fewer side effects.Knut Holt is an internet consultant and marketer focusing on health items.
