Depression Introduction

 

Depression is a clinical syndrome marked by alterations in the normal mood of an individual.  This condition usually denotes a low, or sad mood.  It also affects the physical and mental plains of the individual.  There are several different forms of depression, and the classification for the varying forms of depression is dependant upon the severity of exhibited symptoms.  For the purpose of this article, "depression" will refer to both the mild and moderate categories.  The 3 most common types of depression are major depression, dysthymia, and bipolar disorder. [1]

 

Depression is thought to be caused by a chemical imbalance of certain neurotransmitters in the brain.  The most commonly affected of these neurotransmitters is often serotonin, which is the chemical directly associated with feelings of happiness and positive mood. If an imbalance is present, persons are more susceptible to depression when a stressful life event occurs.  There is also a belief that depressive states may be part of a familial component, as it tends to run in families.  However, history shows that this condition does not always follow this trend. [2]

 

There are no specific time frames on the duration of mental anguish once an individual is diagnosed with depression.  Episodes often occur only once in an individual's life. However, many individuals do have a life-long struggles with depressive episodes.
