blunted affect
Reduced emotional expression and responsiveness, appearing as diminished facial expressions and vocal inflection.
Full Definition
Blunted affect is a clinical term describing a significant reduction in the intensity and range of emotional expression. Patients with blunted affect show diminished facial expressions, reduced vocal inflection, and limited gestural communication, making them appear emotionally unresponsive or detached. This symptom is commonly observed in schizophrenia spectrum disorders, depression, and certain neurological conditions. Blunted affect exists on a spectrum from mild reduction to complete absence (flat affect) of emotional expression. It's important to distinguish blunted affect from the subjective experience of emotions, as patients may feel emotions internally while appearing externally unexpressive. Assessment involves observing the patient's facial expressions, tone of voice, and body language during the clinical interview.
Usage
Usage note: Hyphenate as compound modifier. Distinguish from flat affect (complete absence) and the patient's subjective emotional experience.
