<unk>  is a medical condition characterized by the inability to control facial movements (such as chewing and speaking) and caused by a variety of neurological disorders. Patients experience difficulty chewing and swallowing, have increased reflexes and spasticity in tongue and the bulbar region, and demonstrate slurred speech (which is often the initial presentation of the disorder), sometimes also demonstrating uncontrolled emotional outbursts. The condition is usually caused by the bilateral damage to corticobulbar pathways, which are upper motor neuron pathways that course from the cerebral cortex to nuclei of cranial nerves in the brain stem.
