Cognitive Theory of Depression

The cognitive theories of depression are considered to be those that address mental events such as thinking and feeling. Different cognitive theorists have developed their own idea of what a cognitive theory is. One of this theorists is the famous Dr. Aaron Beck. According to him, negative thoughts, generated by dysfunctional beliefs, are typically the primary cause of depressive symptoms. There is a great relationship between his two factors stating that the more negative thoughts you experience, the more depressed you will become.

There are several negative beliefs that dominate depressed people´s thought: 1) I am defective or inadequate. 2) All of my experiences result in defeats or failures. 3) My future is hopeless. Together, these three beliefs are described as the Negative Cognitive Triad. When these beliefs are present in someone's cognition, depression is very likely to occur, if it has not already occurred.

Envionmental Theory 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 happen in the course of our everyday lives.

The enviornmental factor is of great importance in depression. This factor, which can also be called emotional factors, is caused from stressful emotional situations, such as a death of a living one, especially at a young age, or prolonged stress at home or work, and even a traumatic event. The enviornmental factor can also be kown as sociological or psychosocial factors since they bring together events that happen out in society and are linked with the people's mind.

Biological Theory of Depression

In the past, scientists thought that depression was the results of thoughts and emotions that were troubling in a person. Now, scientists have realized that there are severals aspects that workiin one's brain that can lead to depression. For example, then biological factor.

Biological causes are due to changes of chemistry in the brain, such as fluctations in the levels of important hormones. People usually have problems in the neurotransmitters, which are natural substances that allow that allow brain cells to communicate with eachother. Two of the transmitters that are implied in depression are serotonin and norepinephrine. Furthermore, deficiency in serotonin causes the sleeping problems, irritability, and anxiety. Likewise, a decreased amount of norepinephrine contributes to the fatigue and illness in depression.
