Viliuisk encephalomyelitis (VE) is an unique neurological disease occurring in the Iakut (Sakha) people of Siberia. Evolution of the disease follows one of three broad clinical forms: subacute, slowly progressive or chronic. Death occurs within 3 to 6 months in subacute cases and within 6 years in the slowly progressive cases. Chronic cases lack a subacute phase but show a slowly progressive dementia associated with bradykinesia, dysarthria and spastic paraparesis that stabilizes late in the disease process. In subacute and slowly progressive cases, focal necrotizing encephalomyelitis is seen at necropsy. Chronic cases show multifocal areas of lysis with a gliotic margin, predominantly within grey matter, lacking associated chronic inflammatory changes seen in the other forms of the disease. Epidemiological studies are consistent with a disease of low-grade communicability, but laboratory studies have so far failed to reveal an infectious organism. The spectrum of neuropathological changes are reviewed in this examination of 11 cases. Although the aetiology of VE remains obscure, further studies are warranted since it may represent a novel disease process.

Autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy is a newly recognized autoimmune central nervous system (CNS) inflammatory disorder, presenting with an array of neurological symptoms in association with autoantibodies against GFAP, a hallmark protein expressed on astrocytes. Limited knowledge is available on the disease pathogenesis and clinical outcome. Here, we report a case of autoimmune GFAP astrocytopathy presenting with encephalomyelitis and parkinsonism. Our patient was a 66-year old male who experienced progressive somnolence, apathy, anxiety, right arm tremor, urinary retention, progressive weakness, and falls over the course of three months, followed by acute delusional psychosis. His neurologic exam on hospital admission was notable for cognitive impairment, myoclonus, rigidity, right hand action tremor, bradykinesia, shuffling gait, and dysmetria. Cerebrospinal fluid examination showed elevated protein, lymphocytic pleocytosis, and one unique oligoclonal band. Magnetic resonance imaging (MRI) revealed non-specific T2/FLAIR hyperintensities in the brain and longitudinally extensive transverse myelitis in the cervical spine. FDG-PET showed a pattern of brain uptake suspicious for limbic encephalitis. Serum and CSF paraneoplastic panel showed presence of GFAP immunoglobulin G (IgG). Treatment with corticosteroids resulted in clinical and radiographic improvement. However, the patient was treated with anti-CD20 immunotherapy due to steroid-dependence. This case exemplifies the recently described neurologic syndrome of autoimmune GFAP astrocytopathy presenting with encephalomyelitis and parkinsonism, reversed by B lymphocyte depletion.

Dengue fever continues to be an important cause of morbidity and mortality in tropical and subtropical countries. A wide range of neurological manifestations including dengue encephalopathy, Guillain-Barre syndrome, acute disseminated encephalomyelitis, transverse myelitis, cranial nerve palsies, and myositis have been reported following dengue infection. But parkinsonism secondary to dengue virus infection is uncommon, with only three published case reports in adults and one in children. We describe a 13-year-old pre-morbidly normal boy, who presented with bradykinesia, bradyphonia, mask-like facies, and cogwheel rigidity while recovering from uncomplicated DF. He responded favorably to levodopa/carbidopa supplementation and had resolution of symptoms over the next 2 weeks. We also did a comparative review of all published cases of dengue-induced parkinsonism. Post-dengue, parkinsonism is uncommon, and treating clinicians should be aware of this uncommon but treatable neurological complication of a common arboviral infection.
