culture and is expressed differently as well
○ Complicated grief - grief that has maladaptive responses to the loss
○ Is a universal human experience

○ Is not pathology (unless it is delayed or persists past 12 mos)
○ Uncomplicated grief runs a relatively consistent course but can vary
with circumstances
○ Although sadness is prominent, it is not the same as clinical
depression
○ However, in some cases it can develop into depression, and it is
important to distinguish the two
○ In grief, the person remains connected to his family, while in
depression he may withdraw or self-isolate

sadness is pervasive and responds less, or not at all, to suppport
from others

depression function is greatly impaired

grief varies from day to day. In depression the sadness is pervasive
and consistent

significant risk in depression
