There are not many cases that associate causality of beginning of mania and mourning in the literature. It is known that mania is induced by traumatic events but the cases that do not suit stages of development of grief process are evaluated as pathological grief. In this case, the woman who experienced manic episode after her son's death is presented. This case is prepared because mania should be considered as possible grief reaction.
