Which factor suggests that the risk of suicide is high in a patient?

The factor suggesting that the risk of suicide is high in a patient is when the patient's depressive symptoms have recently improved. This may seem counterintuitive; however, it can indicate a heightened risk for suicide for several reasons.

When an individual's depressive symptoms improve, they might have regained some energy and motivation. However, if that improvement occurs suddenly or dramatically, it could signify that the patient has made a decision to end their life and feels relief from the pain of living with depression. Often, patients experiencing severe depression may have felt immobilized and unable to act upon suicidal thoughts; once they regain energy and clarity, they can more easily take steps toward suicide. This phenomenon is sometimes referred to as "suicide paradox"—where improved mood or behavior might mask an underlying risk of suicidal ideation or intent.

Additionally, it's crucial to monitor patients who show a sudden change in their affect, even if that appears positive, as they might still be at risk for self-harm or suicide. Assessing the nuances in a patient's emotional state and behavioral changes is essential in effectively determining their risk for suicide.
