SECTION2第二部分 Thepatternofweaknessandgaitdisturbanceisconsistentwithachronicspasticparaparesissyndrome,beginningintheadulthood,andprogressingsteadily.Thesyndromeincludesuppermotorneuronsigns(increasedmuscletone,hyperactiveDTR,andBabinskisigns)anddeepsensorydisturbances(sensoryataxia)probablyinvolvingthedorsalascendingcolumns.TheinvolvementofsensoryperipheralnervesisunlikelybecauseofthehyperactiveDTR.Therefore,thesignsandsymptomssuggestadiseaseofthespinalcord.Althoughinfrequent,bilateraldamageofthefrontoparietalcortex(e.g.,parasagittalmeningioma)maycauseaslowlyprogressivespasticparaparesissyndromewithsensorysymptomsandsphincterdisturbances. 患者力弱和步态障碍的模式与成年起病的慢性痉挛性截瘫综合征一致,并且进行性加重。该综合征包括上运动神经元征象(肌张力增加,深腱反射活跃和巴氏征阳性)和可能累及到后索产生的深感觉障碍(感觉性共济失调)。因为腱反射活跃,感觉性周围神经的损害不明显。因此体征和症状提示是脊髓疾病。尽管不常见,双侧前额顶叶皮层(如窦旁脑膜瘤)损伤也可以引起伴随感觉症状和括约肌功能障碍的慢性进行性痉挛性截瘫综合征。 Asyndromeofthistypemaybeindicativeofhereditaryspinocerebellardegeneration(Friedrichataxia)oroneofitsvariants.1Inyoungadults,progressivemultiplesclerosis(MS)isa白癜风医院哪家强北京现在好点的治疗白癜风要多少钱啊 |
