Behavioral & Cognitive Disorders
Foix-Chavany-Marie syndrome is a rare cortical form of supranuclear (pseudobulbar) palsy caused by bilateral anterior opercular lesions; in this syndrome there is an “automatic-voluntary dissociation” of motor function of lower cranial nerves. Manifestations include volitional paralysis of masticatory, facial, pharyngeal, and lingual muscles innervated by cranial nerves V, VII, IX, X, and XII, with preserved autonomic and emotional innervation of these muscles. There are 5 predominant clinical groups of Foix-Chavany-Marie syndrome.
