The exact causes for clinical depression are not yet fully understood. There may be a single reason that is responsible for the cause of clinical depression or may be more. Usually more than one factors, collectively, are responsible for the development of clinical depression in any person. These external factors may be physical, psychological, hereditary or enviromental. It should be noted these all these factors may cause the depression in one person but not in the other person. The ability to resist these external factors or triggers is different in different persons. Following are some of the important causes of clinical depression, discussed in detail:
If someone in your family has depression you are more likely to develop the condition yourself, although not necessarily. Studies show that versions of the 5-HTT gene are inherited, and that in people with depression the "short version" of this gene is present. But the person with no family history of depression may also become depressed at any stage of life.
Stress is the major and common cause for the development of clinical depression. Stresses are mainly of 2 types. These are enviromental stresses and psychological stresses. The enviromental stresses may be different for every person because of the different enviroment. For example the clinical depression may be developed in the students because of the burden and demands from the college. Also the tension of exams or test may be the cause. Another major stress causing factor may be the worries of finding the perfect job after the studies etc. The other reasons of stress may be some big loss like the loss of your best friend or financial crisis etc. The severe disease or illnes and disturbance in the relations with the family are also the important factors that can cause clinical depression. Stress can induce the depression in any individual that may or may not have any family history of depression.
The psychological factors play an important role in the development of clinical depression in any individual. It is seen that usually people having less self confidence are easily depressed. Some people have very pessimistic thought and approach and that is another cause of clinical depression. The people having these psychological problems may become depressed without any other external or enviromental trigger. But if the enviromental stresses are also added, then the severe type of clinical depression may be seen in these people.
The use of alcohol or similar type of drugs may be the direct cause of clinical depression. In some other persons the cause of development of clinical depression is different and people start taking the alcohol to escape from the depression symptoms. Unfortunately this escape is not permanent. The use of alochol or drugs simple increases the symptoms of clinical depression. It is not important to find out that alcohol was the reason of depression of depression was the reason alcohol. The important thing is that you should start your treatment to recover from the symptoms of clinical depression. It should also be nothed that the medicines taken for depression may not work effectively if you are taking the excessive amount of alcohol.
Sometimes the medicines used to cure certain diseases, become the cause of depression in the patients. Usually it is seen that calcium channel blockers and beta blockers and some other medicines cause depression in some patients. If you are taking any of these medicines or any other type of medicines regularly and you have the symptoms of depression, then you should consult to your doctor. If any medicine is the cause then you can use some alternate medicine for your illness.
