<h3>What is
flat affect?</h3>
A flat affect, or lack of emotional expression, can be a negative symptom of schizophrenia. You may speak in a monotone, flat tone, and your expression may remain unchanged. You may also have difficulty understanding other people's emotions.
Those who sustain a traumatic brain injury as a result of a blow to the head, a fall, a blast injury, or another violent incident may experience post-trauma flat affect. In addition to blunt trauma, brain injuries caused by strokes, particularly right hemisphere strokes, can result in flat affect.
People with a flat affect show almost no outward signs of emotion. Affect has been softened. People with blunted affect exhibit very little outward emotion.
