Aprosodia is a neurological disorder that affects the ability to comprehend and express emotions through speech and tone. Synonyms for this condition include emotional deficits, flat affect, and affective agnosia. Other terms used to describe the lack of emotional inflection in speech include dysprosody and monotone speech. Aprosodia is typically caused by damage to the right hemisphere of the brain, where language and emotion processing are located. People with the disorder may struggle to understand sarcasm or irony and may have difficulty conveying empathy or expressing themselves in social situations. Treatment for aprosodia often involves speech therapy and counseling to address emotional and communication deficits.
