摘要
步态冻结(FOG)在帕金森病的病程中经常出现,并导致这些患者产生依赖性。最常见的临床形式是关闭性步态冻结(OFF FOG)和非多巴反应性步态冻结(Non-dopa-responsive FOG),前者在开启状态下消失,后者在开启状态下持续存在。我们报告了一例罕见的 FOG ON 病例,该病例由大剂量左旋多巴诱发,并在 OFF 状态下消失。其病理生理学可能与峰值剂量运动障碍相似。步态冻结(FOG)在帕金森病的病程中经常出现,并导致患者产生依赖性。最常见的临床形式是关闭性步态冻结(OFF-FOG)和无反应性步态冻结(unresponsive FOG),前者在开启状态下消失,后者在开启状态下持续存在。我们报告了一例罕见的 ON-FOG 病例,该病例由大剂量左旋多巴诱发,并在 OFF 状态下消失。其病理生理学可能接近于峰值剂量运动障碍。治疗具有挑战性,我们将对此进行讨论。
Enrayage cinétique (ou freezing of gait) sévère persistant en ON : essayez de diminuer la lévodopa !
Le gel de la marche (FOG) survient fréquemment au cours de l’évolution de la maladie de Parkinson et participe à la dépendance de ces patients. Les formes cliniques les plus fréquentes sont le FOG OFF, qui disparaît à l’état ON, et le FOG non dopa-sensible, qui persiste à l’état ON. Nous rapportons un cas rare de FOG ON induit par de fortes doses de lévodopa et disparaissant à l’état OFF. La physiopathologie pourrait être proche de la dyskinésie de pic de dose. Le traitement est difficile et sera discuté.
Freezing of gait (FOG) occurs frequently in the course of Parkinson's disease and participates in dependence of these patients. The most frequent clinical forms are OFF-FOG, which disappears in ON state, and unresponsive FOG, which persists in ON state. We report a rare case of ON-FOG, which was induced by high levodopa doses and disappeared in OFF state. Pathophysiology could be close to peak dose dyskinesia. Treatment is challenging and will be discussed.
