ABSTRACT

Objective Linguistic problem is common in Huntington's disease (HD) patients. It has been studied before in native speakers of alphabetic languages, such as English. As a hieroglyphic language, Chinese differs from alphabetic languages in terms of phonology, morphology, semantics and syntax. We aimed to investigate the linguistic characteristics of manifest HD in native speakers of Mandarin. Meanwhile, we expected to explore the linguistic differences associated with cortical or subcortical pathology.Methods Five HD patients and five Alzheimer's disease (AD) patients matched in age, gender, disease course and educational level were enrolled. All the participants were Mandarin native speakers. All finished history inquiry, physical examination, basic test, genetic test and neuropsychological assessment. Language evaluation was performed by Aphasia Battery of Chinese.Results HD patients had a mean disease course of 5.4±2.97 (range, 2-10) years. They showed a linguistic disorder close to transcortical motor aphasia. They exhibited prominent phonological impairment, as well as slight semantic and syntactic abnormality. Tonic errors were found in speech. Character structural errors and substitutions were detected in writing. In comparison, AD patients showed a more severe linguistic impairment, characterized by global aphasia with more semantic errors. Conclusion Mandarin-speaking HD patients have a transcortical motor aphasia-like disturbance with prominent phonological impairment, whereas AD patients have a more severe global aphasia with salient semantic impairment.

ABSTRACT

Objective To explore the clinical characteristics of autoimmune disease with dual seropositive antibodies of leucine-rich glioma inactivated 1(LGI1)and contactin-associated protein 2(Caspr2).Methods The clinical data of seven patients with dual seropositive LGI1 and Caspr2 antibodies who were admitted to the Neurology Department of Peking Union Medical College Hospital from July 2014 to December 2017 were retrospectively analyzed.Results Central,peripheral and autonomic nervous systems were all involved in the seven cases;100%(7/7)presented with insomnia,myokymia,neuropahic pain and hyperhydrosis;71%(5/7)showed memory decline or psychiatric and behavioral symptoms;57%(4/7)had urinary hesitation or constipation;and 43%(3/7)had seizure.Electromyography showed 100%(6/6) of the patients had prolonged afterdischarges following normal M waves and/or abnormal spontaneous firing.Electroencephalography revealed slow waves or basic rhythm slowing in 71%(5/7)of patients.Electrocardiography showed sinus tachycardia,axis deviation,and prolonged QT intervals in 71%(5/7)of patients.One patient died from arrhythmia before immunotherapy.One died from pulmonary infection after immunotherapy.Improvement with immunotherapy was documented in the other five cases.No relapse was noted during the 1-2-year follow-up.Conclusions Autoimmune disease with dual seropositive antibodies of LGI1 and Caspr2 can diffusely affect the central,peripheral,and autonomic nervous systems.The possibility of this disease should be considered in patients with acute and subacute onset of neuropsychiatric symptoms,especially in patients with accompanying insomnia,myokymia,and hyperhydrosis.
