Unlabelled: Background: Anti-LGI1 encephalitis is characterized by a pattern of inflammation that predominantly affects the limbic system It is part of the autoimmune encephalitis that attack neuronal surface antigens. It is characterized by the triad of subacute dementia, faciobrachial dystonic crises, and hyponatremia, presenting an excellent response to immunotherapy. The aim of this article is to describe the clinical evolution and functional outcome at 6 months of two patients with anti-LGI1 encephalitis using clinical cases.

Clinical Cases: Case 1: 62-year-old man with 8-week symptoms manifested by changes in mood, disorientation, and focal motor seizures. Case 2 A 72-year-old woman with a 5-month evolution of rapidly progressive dementia, hyponatremia and bitemporal hyperintensities on MRI. In both, due to clinical suspicion, acute dual immunotherapy with steroid and immunoglobulin was given with substantial improvement. Subsequently, the existence of anti-LGI1 antibodies in cerebrospinal fluid was confirmed. Although both patients received a dose of rituximab during their hospitalization, only the patient in the first case continued biannual doses of rituximab. The second patient was not initially considered to continue long-term immunomodulatory treatment and experienced a relapse.

Conclusions: These clinical vignettes present the reader with the classic characteristics of this disease. This can facilitate its recognition and timely initiation of treatment, improving the functional prognosis of patients.

The long-term clinical outcomes and associated prognostic factors in contactin-associated protein-like 2 (CASPR2)-antibody diseases are unknown. A total of 75 participants with CASPR2 antibodies were longitudinally assessed for disability, quality-of-life, and chronic pain. Although most symptoms improved within 6 months of treatment, neuropathic pain and fatigue were the most immunotherapy refractory, and persisted for up to 6 years.

Background: Headaches are more prevalent in patients with multiple sclerosis compared with the general population. However, headaches are still considered a rare symptom of multiple sclerosis, especially when they appear as an initial symptom. The occurrence of a headache as a symptom of radiologically isolated syndrome (RIS) is uncommon, and it can significantly increase the likelihood of developing multiple sclerosis.

It has been reported that the nervous system can regulate immune reactions through various mechanisms. However, the role of splenic sympathetic nerve activity in the autoimmune reactions during the pathogenesis of experimental autoimmune encephalomyelitis (EAE) remained unclear. Here, we blocked the activity of the splenic sympathetic nerve and found that the number of adaptive immune cells, such as CD4 T cells, CD8 T cells and B cells, were upregulated.

Vision loss affects more than 7 million Americans and impacts quality of life, independence, social functioning, and overall health. Common and dangerous conditions causing sudden vision loss include acute angle-closure glaucoma, retinal detachment, retinal artery occlusion, giant cell arteritis, and optic neuritis. Acute angle-closure glaucoma features ocular pain, headache, and nausea; treatment includes pilocarpine eye drops, oral or intravenous acetazolamide, and intravenous mannitol.

Background And Objectives: Despite the absence of acute lesion activity in multiple sclerosis (MS), chronic neurodegeneration continues to progress, and a potential underlying mechanism could be the kynurenine pathway (KP). Prolonged activation of the KP from chronic inflammation is known to exacerbate the progression of neurodegenerative diseases through the production of neurotoxic metabolites. Among the 8 KP metabolites, six of them, namely kynurenine (KYN), 3-hydroxylkynurenine (3HK), anthranilic acid (AA), kynurenic acid (KYNA), and quinolinic acid (QUIN), have been associated with neurodegeneration.
