Emotional Blunting in Patients With Major Depressive Disorder: A Brief Non-systematic Review of Current Research

Summary & key facts

This paper reviews research about emotional blunting in people with major depressive disorder, which is the clinical name for depression. Emotional blunting means feeling less emotion or feeling numb. Patients often report it, and it is seen as one of the common side effects of antidepressant medicines. Researchers say the problem is not well defined and we do not know exactly what causes it, but higher drug doses seem linked to more blunting. Doctors often try lowering the dose or switching medicines, and the review says we need better ways to measure and study this symptom.

Key facts:

• Many people with major depressive disorder report emotional blunting, which feels like a reduced ability to experience positive or negative emotions.
• Emotional blunting has been identified as a common side effect of antidepressant medicines and is often given as a reason why people stop taking their medication.
• Scientists and clinicians do not agree on a clinical definition for antidepressant-induced emotional blunting, and the exact causes are unclear.
• Some research suggests that higher doses of antidepressants are more likely to be linked with emotional blunting than lower doses.
• When patients report emotional blunting, clinicians commonly either reduce the antidepressant dose or switch to a different drug, but there is no single agreed treatment approach.
• The review calls for better clinical assessments and interviews designed specifically to measure antidepressant-induced emotional blunting and to study the brain and mental processes behind it.

Abstract

Emotional blunting is frequently reported by patients with major depressive disorder (MDD) and has been identified as one of the most prominent side effects of antidepressants leading to medication discontinuation. However, antidepressant-induced emotional blunting remains largely unexplored-there lacks a clinical definition of this condition, and no agreeing conclusion has been reached regarding its etiology. Current research suggests that the onset of diminished emotional response may be related to antidepressant dose, with higher doses being more likely to induce emotional blunting. Consequently, most clinicians either reduce the dose or switch to another drug when treating this symptom. Overall, more comprehensive clinical assessments or interviews specifically designed to evaluate antidepressant-induced emotional blunting in MDD patients are in need to elucidate the neuropsychological mechanisms behind this increasingly prevalent symptom.
