It is normal to experience profound sadness after the loss of a loved one, including symptoms such as insomnia and poor appetite. The DSM-5 terms this experience “uncomplicated bereavement” and describes it as a topic that may be a focus of clinical attention.
The DSM-5 also proposed Persistent Complex Bereavement Disorder as a condition for further study. This disorder would describe those who experience distressing symptoms of bereavement such as persistent longing, intense sorrow, and preoccupation with the death more than a year after the death of a loved one.
