Unfortunately, it is not fully known what exactly causes clinical depression for a particular
|
|
individual. There are many theories about causes such as biological and genetic factors,
|
|
environmental influences, and childhood or developmental events. However, it is generally
|
|
believed that clinical depression is most often caused by the influence of more than just one or
|
|
two factors. For instance, a person whose mother had recurrent major depression may have
|
|
inherited a vulnerability to developing clinical depression (genetic influence). This combined
|
|
with how the person thinks about him- or herself (psychological influence) in response to the
|
|
stress of going through a divorce (environmental influence), may put him or her at a greater
|
|
risk for developing depression than someone else who does not have such influences.
|
|
The causes of clinical depression are likely to be different for different people. Sometimes a
|
|
depressive episode can appear to come out of nowhere at a time when everything seems to
|
|
be going fine. Other times, depression may be directly related to a significant event in our
|
|
lives such as losing a loved one, experiencing trauma, or battling a chronic illness.
