RESUMEN
A variety of anti-neuronal cell membrane antibodies such as voltage-gated potassium channel antibody, N-methyl-D-aspartate-2B-antibody, and glutamic acid decarboxylase antibody, are correlated with limbic encephalitis (LE). In this study on patients with LE, the clinical manifestations, psychology Wechsler Adult Intelligence Scale, cerebrospinal fluid, electrophysiology, magnetic resonance imaging, and anti-immune therapy were studied and immunological determination was conducted; it was found that patients of Chinese Han nationality showed 2 types of clinical manifestations: simple and complex. Lesions could also be divided into focal and scalable lesions, and the clinical manifestations and lesions scopes were associated with various antibodies and antibody types. The prognosis may improve if early diagnosis is conducted and early anti-immune therapy is implemented in LE patients.

Limbic encephalitis (LE) can be associated to cancer, viral infection or be idiopathic. One form is associated to voltage dependent potassium channel (VKC) antibodies. The clinical presentation includes impairment of consciousness, amnesia and temporal lobe seizures; typical abnormalities are also found in brain magnetic resonance. We report a 68 year-old male who had LE associated to VKC antibodies. The patient was treated with steroids with a partial response. At the moment of the report he is asymptomatic and continues with prednisone treatment .

Recently characterized as an immune-mediated channelopaty, Isaacs' syndrome (also known as acquired neuromyotonia) was first described in 1961 in two men with persistent, generalized muscle stiffness, in addition to spontaneous, rapid discharges of motor-unit potentials on electromyography. In the peripheral nervous system, antibodies targeted to voltage-gated potassium channels induce hyperexcitability of motor axons, resulting in signs of muscle stiffness or of pseudomyotonia. A spontaneous burst of single motor-unit activity, and myokymic and neuromyotonic discharges, are the most characteristic features found in electromyography studies. This report describes Isaacs' syndrome in a child, in whom the diagnosis was made by clinical features of acquired, spontaneous muscle overactivity and typical electromyographic findings.
