Depression is a very widespread problem today affecting one in four women and one in eight men. Many people are aware of the many symptoms of depression, including feelings of hopelessness or helplessness, obsessive negative thoughts, loss or gain in appetite, insomnia or an increased need for sleep, social withdrawal, irritability and loss of memory or concentration, and recurrent thoughts of death or suicide. It is tempting to think that depression is sadness and the causes of depression will simply disappear and the negative feelings will subside. However, the causes of depression are not so simple, and while a negative event may trigger depression, the causes of depression are not external factors alone. Many of the causes of depression are issues with the sufferer.
Causes of depression are 40 – 70% hereditary and children of depressed children are more likely to be depressed. This would mean that the potential for depression lies in one's genetic makeup, and a stressor may trigger a latent potential for depression. However those who dispute heredity as one of the causes of depression cite other true observations that those who live with depressed individuals are more likely to be depressed, and a depressed parent may lack parenting skills or the necessary energy or patience to deal with a child properly, and may be one of the causes of depression. It is hard to know who really wins the nature versus nurture argument, but once we learn more about the role heredity plays among the causes of depression, the better we will understand how genes have an impact on our moods.
Whether causes of depression are hereditary or not, there is a physiological basis for the problem, which refutes claims that depression is nothing more than a bad mood that will pass. Low serotonin levels have been shown to be one of the causes of depression, and loss of neurotransmitters in the hippocampus has also been identified as one of the causes of depression. Seasonal affective disorder is also one of the causes of depression, and it has been shown that those who are deprived of light and warmth in the wintertime and become depressed as a result are not merely suffering from the “winter blues" but have a problem caused by the shorter days and longer nights. Seasonal effective disorder can develop into full blown depression if it not treated as one of the series causes of depression. Hormones may also play a role as one of the causes of depression, especially among those women who suffer from Pre Menstrual Syndrome or post-partum depression. In fact, while one out of every four women suffers from depression compared to one in every eight men, this discrepancy disappears among women who have undergone menopause, when there are lower levels of estrogen. More study is needed to determine whether these hormonal fluctuations are actual causes of depression, or merely triggers.
Losing one's job, getting a divorce or a death in the family may not be actual causes of depression, but they can trigger the problem in those who have a predisposition for the problem. Certainly, such events can cause sadness and a feeling of worthlessness, but if these feelings are not persistent, they are normal aspects of the grieving process and are not causes of depression. However, if the negative feelings are prolonged and obsessive, they may be triggers in setting off depression. There are some physical aliments which are included among causes of depression. Hepatitis and heart conditions can be causes of depression, in addition to Aids and other illnesses which cause weakness and fatigue.
The Causes Of Depression
Psoriasis is a condition of the skin that is little understood. The underlying cause appears to be an autoimmune disorder that causes the body to produce new skin cells at an accelerated rate that leads to the inflammation and itching that is characteristic with psoriasis. Normally skin cells take 28 to 30 days to grow to maturity, but in people who have an outbreak of psoriasis this process is shortened to 3 to 6 days. The scaling, itching and inflammation of the skin is caused by the over build-up of skin cells.
It is believed that the main cause of psoriasis is driven by a certain type of white blood cell known as a T-cell. T-cells are one of the body's defenses against disease and infection, but in the case of psoriasis they leap into action unintentionally and begin to trigger other immune systems which accelerate the creation of new skin cells. Because the skin cells grow and mature quicker then normal they also die off much faster, creating a build up of dead skin cells on the surface. This build up of dead skin cells forms the characteristic plaques, or flaky patches, that sufferers of psoriasis are familiar with. The redness and inflammation of the underlying skin is a product of the increased blood supply needed to feed the new skin cells that are growing at an accelerated rate below the plaques.
While anyone at any age can suffer from psoriasis researchers have found that people in their thirties and sixties are more likely to develop this skin condition than people in other age groups. Why this is the case no one knows. It is also apparent that heredity can be a marker for an increased chance of contracting psoriasis. Children who have one parent who suffers from psoriasis have a ten percent chance of contracting the disease. That percentage goes up dramatically to fifty percent if both parents have this condition. Scientists, who have done studies on families afflicted with psoriasis, have been able to identify genes that are known links to the condition.
The exact causes of psoriasis remains something of a mystery but there are known triggers that are linked to outbreaks. Many people who suffer from this disease notice that there are times the condition is worse and times it seems to get better. Reactions to certain drugs, such as lithium and beta blockers, have been shown to trigger a psoriasis outbreak and in extreme instances make the condition worse.
Because psoriasis is caused by a faulty immune system anything that stimulates the body's defenses can bring about an outbreak. An injury such as a cut or bruise or an infection, particularly strep, can all cause an outbreak.
Another factor that can cause an outbreak of psoriasis is stress. People who suffer from psoriasis have noticed that as their stress levels go up so does the potential for a severe outbreak of their skin inflammation. Psoriasis in and of itself also causes stress leading to a self perpetuating problem of continual outbreaks that increase in severity as a person's stress level increases.
One way that psoriasis cannot be caught is through contact with someone who suffers from the disease. It is not a contagious skin condition, and although it is unsightly and can cause repulsive reactions from those who do not suffer its affects it is important to remember that those who suffer from it need the reassurance and support of friends and family along with proper treatment to help them live a normal life.
