Anti-NMDA受体抗体相关引起的脑炎最近诊断为神经精神症状在儿童和成人可以代表一个重要的对临床医生诊断挑战。临床症状通常包括脑病、最近诊断为精神疾病和运动现象。尽管orofacial动作障碍最初被确定为一个特征运动现象在这种类型的脑炎,扩大范围的异常最近报道,包括孤立性共济失调。我们报告一个孤立的hemiataxia与温和的年轻人最初的精神表现。前的个人和家庭历史产生的神经精神症状的诊断混乱和导致一个重要的诊断和治疗延迟。我们的案例证实了单方面的运动表现,强调在最近的报告。此外,它证实了神经的参与的必要性以及精神服务评价的这种情况下,强调神经系统检查的重要性与最初的精神优势介绍。
Anti-NMDA受体抗体相关脑炎是日益公认的原因最近诊断为神经精神症状在儿童和成人
我们的病人,一个18岁的女性,被称为神经病学与分裂情感性障碍的诊断后首次发作。她经历过先前的情绪不稳定性和注意力障碍作为一个青少年,治疗期间。然而,她已经治疗5年,在最近的过去一直做得很好。成绩和体育功能是高于平均水平,她在高中时参加了三项体育活动,在主流类。她的家族史是著名的母亲抑郁史,心因性nonepileptic癫痫,和焦虑,以及一个姥姥报道精神分裂症和双相情感障碍的历史。八个月前患者的转诊神经学,她经历了一个自限性的疾病表现为腹泻、头痛和呕吐。这是托管在家里,虽然她被她的初级保健提供者和诊断出患有病毒性肠胃炎。大约一个月后,她开始经历失眠、情绪不稳,和减肥。内存问题随之而来,和家长报告说,她开始经常失去对象和难以记住的公交线路。个人卫生了,恶化的症状4个月后,她开始每周次尿失禁。 There were no other autonomic manifestations. Throughout the course of the subacute illness, she experienced a “tremor” of the left upper extremity when attempting to manipulate or reach for objects, as well as dragging her left foot when ambulating. She received ongoing psychiatric treatment and monitoring, and her movement phenomenon was attributed to a psychogenic cause, and a diagnosis of likely schizoaffective disorder was made. After 7 months of symptoms, she experienced a spell, characterized by clonic movements of the left hand, followed by tonic stiffening of her entire body, with right sided head and neck deviation, lasting 30 seconds, followed by confusion and sedation. She recovered to baseline after 30 minutes. After this episode, she was referred to neurology. On initial presentation to our service, her spell was attributed to a first-time seizure by history. Mental status examination demonstrated a distracted and labile demeanor. Cognition was impaired on both bedside and formal neuropsychological testing with impairments in memory, attention, and reasoning. Neurologic examination demonstrated left sided dysmetria as well as gait disturbance arising from left lower extremity coordination impairment. MRI of the brain revealed increased FLAIR signal of the left hippocampus. No cerebellar or contralateral brain findings were identified as potential substrate for her unilateral ataxia. Electroencephalogram was normal. The combination of her ataxia, cognitive decline, and incontinence prompted an extensive laboratory evaluation for systemic conditions as well as inborn errors of metabolism. Spinal tap was performed, with testing for autoimmune and inflammatory conditions. Testing was positive only for the presence of NMDA receptor antibodies in the spinal fluid (NMDA-R Ab IF Titer Assay, CSF Positive 1 : 4 and reference < 1 : 2, Mayo Clinic Laboratories) with no evidence of active infection or inflammation. Extensive evaluation for a neoplastic substrate, specifically ovarian teratoma, was negative. Because of the extended course experienced by the patient she was started on an aggressive regimen of immune modulation, including concurrent intravenous immunoglobulin, IV methylprednisolone, and rituximab. Although her parents report that psychiatric symptoms were improving after 3 months of treatment, she continues to require medical treatment for her psychiatric manifestations and has been unable to return to school or employment. Additionally, her movement abnormalities persist.
