Biological Depression's Definition and Impact

If you are feeling blue, and depression frequently affects you, then you may be suffering from biological depression. The definition of this condition is still being developed, as the biology of depression is an area of active research in mental health. It can be difficult to wade through the medical literature on the topic. This article makes your life a bit easier by simplifying the available information on biological depression's definition and effects.

What is Biological Depression's Definition?
Biological depression's definition is simple to write and difficult to understand. It is depression that results from biological factors, as opposed to external stimuli. There are many theories, which postulate the potential causes of biological depression, but only one thing is certain. It exists. This is known, because the brain patterns, chemical signatures, and brain activity differ in persons that suffer from depression.

Is All Depression Biological?
To date, biological depression's definition is not all encompassing. There may be many types of depression. Researchers, doctors, and investigators are only now beginning to understand the role of biology in depression. There are still skeptics regarding the existence of the phenomenon. Biochemical explanations for the condition are complex, but for now, it is thought that biology may play a role in the majority of cases of depression.

What Are the Primary Theories of Biological Depression?
Biological depression's definition is rather broad. As a result, many theories fit well within it. The most popular of these is the monoamine hypothesis. Other theories include genetic factors and circadian rhythm effects. The monoamine hypothesis states that the function or malfunction of neurotransmitters may be to blame for depression. Many antidepressants on the market target the behavior of these chemicals, and appear to work fairly well. Still, the monoamine hypothesis has been criticized widely.

How Does Biological Depression Affect Sufferers?
The determination of biological depression does not set a definition for a particular person's symptoms. There are some general characteristics of depression that are common across individuals, such as feelings of helplessness, worthlessness, or self-doubt. There are many other symptoms as well that are characteristic of depression. If you are feeling down, and you have a hard time finding anything positive to focus on, then you might want to seek professional help. Regardless of the causes of depression, the condition is often treatable.
