Systemic Inflammation Is Associated With Neurologic Involvement in Pediatric Inflammatory Multisystem Syndrome Associated With SARS-CoV-2
Conclusions Broad neurologic features were found in 12% patients with PIMS-TS. By 3-month follow-up, half of these surviving children had recovered fully without neurologic impairment. Significantly higher systemic inflammatory markers were identified in children with neurologic involvement and in those who had not recovered fully.

Presentations and mechanisms of CNS disorders related to COVID-19
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of the coronavirus disease 2019 (COVID-19) pandemic. In addition to severe respiratory symptoms, there are a growing number of reports showing a wide range of CNS complications in patients with COVID-19. Here, we review the literature on these complications, ranging from nonspecific symptoms to necrotizing encephalopathies, encephalitis, myelitis, encephalomyelitis, endotheliitis, and stroke. We postulate that there are several different mechanisms involved in COVID-19–associated CNS dysfunction, particularly activation of inflammatory and thro...

CNS inflammatory vasculopathy with antimyelin oligodendrocyte glycoprotein antibodies in COVID-19
A 44-year-old right-handed woman reported a gradual onset of right hand incoordination seven days after the onset of minor respiratory symptoms and pruritus due to COVID-19 infection. Over 48 hours, the patient developed word-finding difficulties and progression in right arm weakness leading to presentation to the emergency department as a suspected stroke.

Varicella-zoster virus CNS vasculitis and RNA polymerase III gene mutation in identical twins
Conclusions Altogether, these cases add genetic and immunologic evidence to the novel association between defects in sensing of AT-rich DNA present in the VZV genome and increased susceptibility to severe manifestations of VZV infection in the CNS in humans.

Dacrystic seizures--a cry for help
A 69-year-old man with a history of myocardial infarction presented with crying-like spells. MRI demonstrated abnormal signal in the left mesiotemporal lobe, and he was diagnosed with stroke. Over the following 1 year, he developed progressive cognitive decline, slow gait, masked facies, hypophonic voice, and brief facial and upper extremity spasms (8 per hour) often followed by brief crying spells lacking emotion. Spell semiology was consistent with faciobrachial dystonic seizures1 and dacrystic seizures2 (video at Neurology.org/nn). Leucine-rich glioma-inactivated-1 (LGI1) autoantibodies, detected in serum, led to a diag...

Progressive multifocal leukoencephalopathy during fumarate monotherapy of psoriasis
In September 2013, a 69-year-old Caucasian man who was anti–JC virus (JCV) antibody positive was admitted to our hospital with slowly progressing right hemiparesis and aphasia lasting for approximately 6 months. Medical history revealed arterial hypertension, biological aortic valve replacement, and psoriasis vulgaris, treated with 3–6 tablets daily of dimethylfumarate (DMF; 120 mg)/ethylhydrogenfumarate (EHF; 95 mg) (Fumaderm, Biogen Idec, Ismaning, Germany) since December 2008 (table e-1 at Neurology.org/nn). No other immunosuppressive pretreatment had been given. In April/May 2013, the patient recognized a s...
