Muteness of Cerebellar Origin

Arch Neurol. 1985;42(7):697-698. doi:10.1001/archneur.1985.04060070091023

• Acute bilateral damage to large areas of both cerebellar hemispheres including the dentate nuclei led to temporary loss of speech in six children. In each case muteness was unassociated with motor paralysis, loss of higher cognitive functions, or cranial nerve dysfunction. Muteness lasted one to three months. All patients were severely dysarthric during recovery. We conclude that transient muteness may result from acute bilateral cerebellar injury.
