Monoparesis (monoplegia) and cranial mononeuropathy. Peripheral/cranial nerve and nerve root diseases.

Monoparesis (monoplegia) refers to partial (monoparesis) or complete (monoplegia) loss of voluntary motor function in a single limb. Cranial mononeuropathy implies that there is dysfunction referable to a single cranial nerve. These neurologic problems are generally associated with peripheral and cranial nerve lesions, respectively. These problems are discussed together here because similar, if not identical, diseases are involved.
