Biological Causes of Depression:
Additional research data indicate that people suffering from depression have imbalances of neurotransmitters, natural substances that allow brain cells to communicate with one another. Two transmitters implicated in depression are serotonin and norepinephrine. Scientists think a deficiency in serotonin may cause the sleep problems, irritability, and anxiety associated with depression. Likewise, a decreased amount of norepinephrine, which regulates alertness and arousal, may contribute to the fatigue and depressed mood of the illness.
Other body chemicals also may be altered in depressed people. Among them is cortisol, a hormone that the body produces in response to stress, anger, or fear. In normal people the level of cortisol in the bloodstream peaks in the morning, then decreases as the day progresses. In depressed people, however, cortisol peaks earlier in the morning and does not level off or decrease in the afternoon or evening.
Researchers don't know if these imbalances cause the disease or if the illness gives rise to the imbalances. They do know that cortisol levels will increase in anyone who must live with long-term stress.
Enviormental Causes of Depression:
Environmental causes of depression are concerned with factors that are outside of ourselves. They are not directly related to brain function, inherited traits from parents, medical illnesses, or anything else that may take place within us. Instead, environmental events are those things that happen in the course of our everyday lives. These may include situations such as prolonged stress at home or work, coping with the loss of a loved one, or traumatic events. Sometimes researchers refer to these as sociological or psychosocial factors since they bring together events that happen out in society with the inner workings of a person's mind.
It has long been understood that experiences we have in our lives can affect our state of mind. The relationships we have with others, how we are brought up, losses we have, and crises we encounter all may affect our thoughts, emotions, and behaviors. How we react to these environmental events may influence the development of clinical depression.
Cognitive Causes of Depression:
Different cognitive behavioral theorists have developed their own unique twist on the Cognitive way of thinking. According to Dr. Aaron Beck, negative thoughts, generated by dysfunctional beliefs are typically the primary cause of depressive symptoms. A direct relationship occurs between the amount and severity of someone's negative thoughts and the severity of their depressive symptoms. In other words, the more negative thoughts you experience, the more depressed you will become.
Cognitive Triad:
The Cognitive Triad is based in 3 beliefs that can cause depression and affect each other. These things are negative views of the self, the world, and to the future. As an example if a soccer player fails a penalty will believe he is a failure, then will believe everyone is against him, and finally he will believe he will fail in a future and would never be good at something.

The study was conducted by Dr. Mahmood I. Siddique, clinical associate professor of medicine at Robert Wood Johnson Medical School in New Brunswick, N.J. It was presented June 9, 2010, in San Antonio, Texas, at SLEEP 2010, the 24th annual meeting of the Associated Professional Sleep Societies LLC. The study involved 262 high school seniors with an average age of 17.7 years who were attending a public high school in Mercer County, N.J. Participant show socio-demographic characteristics using a cross-sectional survey. Too much daytime sleepiness was indicated by a score of 10 or higher on the Epworth Sleepiness Scale, and mood was evaluated with a validated depression scale. The results indicated that high school seniors were three times more likely to have strong depression symptoms if they had excessive daytime sleepiness.
The study was conducted by Lawrence T. Lam, Ph.D., of the School of Medicine, Sydney, and the University of Notre Dame, Fremantle, Australia, and Zi-Wen Peng, M.Sc., of the Ministry of Education and SunYat-Sen University, Guangzhou, China, in August 2010. It will appear in the October print issue of Archives of Pediatrics & Adolescent Medicine. 1,041 teens in China were assessed for depression and anxiety using previously validated scales. They also completed a survey to identify pathological Internet use, including questions that reflect typical behaviors of addiction. At the beginning of the study, 62 participants were classified as having moderately pathological use of the Internet, and 2% were severely at risk. Nine months later, the adolescents were re-assessed for anxiety and depression; 2% had significant anxiety symptoms and 84% had developed depression. The risk of depression for those who used the Internet pathologically was about two and a half times that of those who did not. No relationship was observed between pathological Internet use and anxiety.
The study was conducted by researchers at the University of Bergen, Norway, and the Institute of Psychiatry (IoP) at King's College led by Dr Robert Stewar. The study consisted of a survey of over 60,000, complemented with already existent records. Researchers found that over the following 4 yearsusing the survey, the mortality risk was increased to a similar extent in people who were depressed as in people who were smokers.
