In recent years, research on grief complications has focused on the develop-
ment and validation of Complicated Grief diagnostic criteria for the fifth edi-
tion of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V).
Even though research has shown that complicated grief is a disorder distinct
from other psychiatric disorders such as PTSD and MDD, there are still
concerns about the validation and conceptualisation of the proposed criteria.
In this article, we review findings and different concepts with regard to
complicated grief. Key issues are the currently proposed diagnostic criteria,
differentiation between traumatic and non-traumatic bereavement, and rela-
tional aspects of the grief process.
