- Genetics: depression can run in the family.

- Environmental factors: continuous exposure to violence, neglect, abuse or poverty may make some people more vulnerable to depression.
Certain medical conditions like thyroid problems, a brain tumor or vitamin deficiency can cause symptoms of depression, therefore ruling out other medical causes before a diagnosis is important.1
