How is grief that does not resolve over time classified?

Complicated grief is classified as grief that does not resolve over time and is often marked by persistent and intense sorrow, difficulty in moving forward with life, and a yearning for the deceased that interferes with daily functioning. This type of grief can manifest in various ways, such as prolonged sadness, emotional distress, or longing for the deceased that is disproportionate to the situation and does not diminish over time.

In contrast, transient grief, while painful, typically becomes less intense and allows the individual to adjust and find a new normal. Chronic grief may suggest a long-lasting state of grief but lacks the specific complications that characterize complicated grief. Acute grief refers to the immediate and intense reaction following a loss, which generally evolves into more manageable feelings over time. Complicated grief, however, remains unresolved and can lead to additional emotional and psychological issues, making it distinct in how it affects an individual's overall well-being.
