Some of you may be aware that some of us have no idea about depression. So i thought i would do a little write up on it.
First i think a look at the causes of depression would be handy.
Causes of Depression: Genetics, Illness, Abuse, and More
There are also some biological indicators of depression

Causes of Depression: Genetics, Illness, Abuse, and More
As you should be able to see there a number of different causes of depression.
- Abuse. Past physical, sexual, or emotional abuse can cause depression later in life.
- Certain medications. Some drugs, such as Accutane (used to treat acne), the antiviral drug interferon-alpha, and corticosteroids, can increase your risk of depression.
- Conflict. Depression in someone who has the biological vulnerability to develop depression may result from personal conflicts or disputes with family members or friends.
- Death or a loss. Sadness or grief from the death or loss of a loved one, though natural, may increase the risk of depression.
- Genetics. A family history of depression may increase the risk. It's thought that depression is a complex trait that may be inherited across generations, although the genetics of psychiatric disorders are not as simple or straightforward as in purely genetic diseases such as Huntington's chorea or cystic fibrosis.
- Major events. Even good events such as starting a new job, graduating, or getting married can lead to depression. So can moving, losing a job or income, getting divorced, or retiring.
- Other personal problems. Problems such as social isolation due to other mental illnesses or being cast out of a family or social group can lead to depression.
- Serious illnesses. Sometimes depression co-exists with a major illness or is a reaction to the illness.
- Substance abuse. Nearly 30% of people with substance abuse problems also have major or clinical depression.

Researchers have noted differences in the brains of people who are depressed as compared to people who are not. For instance, the hippocampus, a small part of the brain that is vital to the storage of memories, appears to be smaller in some people with a history of depression than in those who've never been depressed. A smaller hippocampus has fewer serotonin receptors. Serotonin is one of many brain chemicals known as neurotransmitters that allow communication across circuits that connect different brain regions.
