Depression: Causes and Symptoms

Sad looking man looking down
There are many causes and symptoms of depression.

Sometimes your mood sinks and you feel sad for a day or two. This is a normal inevitability of life. However, sometimes the feelings of sadness persist and last for weeks, months or, in extreme cases, even years. This prolonged sense of sadness and hopelessness is known as depression.

Causes

Sometimes it seems unclear as to why someone has become depressed. Sometimes we can point to possible reasons. One important thing to remember is that depression is often the result of more than one factor impacting a person at the same time. The following are possible causes of depression or underlying issues that could contribute to depression:

  • Loss of a loved one or other major loss.
  • Change in life status (moving, divorce, new job, loss of job, school difficulties, etc).
  • Heredity (if a parent suffers from depression, children may be more likely to develop depression).
  • Life stresses (school troubles, relationship problems, dissatisfaction with job, etc.).
  • Past experience with mental disorders—a person who has been diagnosed with a mental disorder may be more likely to develop depression.

Symptoms

Sometimes it’s hard to know when someone is just sad about something and when he or she is depressed.
