目的探讨进行性核上性麻痹(PSP)患者水平眼跳速度谱是否可作为脑干和小脑输出功能障碍的指标,并与Richardson综合征(RS)、PSP-帕金森综合征(PSPp)、单纯运动不能(PAGF)等38例正常人进行比较。结果PSP患者的最大血流速度沿着降低,持续时间延长,尤以减速期明显。这种改变对于较大的靶偏心率(20-30度)更为突出,并且与疾病严重程度相关。PSPc患者的变化最明显,速度轮廓不规则的增加和减少,其次是RS患者,而变化较小的PSPp和正常PAGF patients.ConclusionsSaccade速度轮廓可以是一个指标的脑干和/或小脑输出。PSP患者扫视速度改变可能反映脑干病变,但也可能反映小脑功能障碍,尤其是PSPc.SignificanceSaccade velocity profile可作为潜在小脑/脑干功能障碍的指标。
ObjectiveTo study whether the velocity profile of horizontal saccades could be used as an indicator of brainstem and cerebellar output dysfunction, depending on progressive supranuclear palsy (PSP) subtype.MethodsWe compared the velocity profiles in 32 PSP patients of various subtypes with 38 age-matched normal subjects, including Richardson syndrome (RS), PSP-parkinsonism (PSPp), and pure akinesia (PAGF), and cerebellar subtypes of PSP (PSPc).ResultsPSP patients showed reduced peak velocity along with increased duration, especially in the deceleration phase. This alteration was more prominent for larger target eccentricities (20–30 degrees), and correlated with disease severity. The changes were most pronounced in PSPc patients, with irregular increases and decreases in velocity profile, followed by RS patients, whereas the change was smaller in PSPp and normal in PAGF patients.ConclusionsSaccade velocity profile can be an indicator of brainstem and/or cerebellar output. Altered velocity profile of PSP patients may reflect the pathology in the brainstem, but may also reflect cerebellar dysfunction, most prominently in PSPc.SignificanceSaccade velocity profile may be used as an indicator of latent cerebellar/brainstem dysfunction.
