a speech disorder characterized by disorders of prosodic characteristics of speech, such as intonation, stress, rhythm and melody. Patients with dysprosodia may speak monotonously, with an irregular pitch or irregular rhythm, which affects the emotional and linguistic meaning of utterances. It often occurs due to neurological damage, including lesions of the right hemisphere, cerebellum, or brainstem, and is seen in stroke, traumatic brain injury, and neurodegenerative diseases. Dysprosody makes effective communication and social interaction difficult.
