title: [Eyelid motor impersistence].
abstract: Eyelid motor impersistence is the impossibility shown by some people to maintain voluntary lid closure for a long period. This disorder is not exceptional, and the authors have seen fifteen cases over a short period of time. The phenomenon represents a form of apraxia, and occurs only when the minor hemisphere is damaged with a lesion of the parietal lobe. Diagnosis can often be confirmed by a CAT scan: of the three observations reported by the authors, two were tumors and one a thalamic hematoma. For some authors, motor impersistence is a manifestation of neglect and they include it within the general problem of interhemispheric balance.
