APRAXIA OF THE LARYNX

Disturbances of vocal function in patients with apraxia of speech are well known in the literature and have often been described. Although a praxia of phonation is presumed, only 1 case is mentioned in the liter ature. We present a 51-year-old man (with missing signs of dysarthria and aphasia after spontaneous right temporoparietal hemorrhagia) who h ad aphonia and missing respiration during speaking, whereas articulati on was nearly undisturbed. After differential diagnostic exclusion of other central disorders of phonation we classify this patient as havin g apraxia of phonation or laryngeal apraxia.
