Implementation of prehospital stroke triage is a public policy intervention that can have an immediate impact on acute stroke care in a region. OBJECTIVE To evaluate the impact that a citywide policy recommending prehospital triage of patients with suspected stroke to the nearest primary stroke center had on intravenous tissue plasminogen activator (tPA) use in Chicago, Illinois. ⋯ Implementation of a prehospital stroke triage policy in Chicago resulted in significant improvements in emergency medical services use and prenotification and more than doubled intravenous tPA use at primary stroke centers.

Patients with anti–N-methyl-D-aspartate receptor (NMDAR) encephalitis often develop prominent psychiatric manifestations. The frequency and type of isolated psychiatric episodes (pure psychiatric symptoms without neurological involvement) either as initial presentation of the disease or as relapse are unknown. ⋯ Isolated psychiatric episodes are rare but can occur as initial onset or relapse of anti-NMDAR encephalitis. Recognition of these episodes is important because they respond to immunotherapy. In patients with new-onset psychosis, having a history of encephalitis, subtle neurological symptoms, and/or abnormal results on ancillary tests should prompt screening for NMDAR antibodies.

Case Reports
Vascular complications of fungal meningitis attributed to injections of contaminated methylprednisolone acetate.
Fungal meningitis due to injections of contaminated methylprednisolone acetate can present with vascular sequelae in immunocompetent individuals. This is particularly germane to neurologists because better recognition of the clinical characteristics of patients with fungal meningitis and ischemic stroke will provide more timely and efficient care. ⋯ Patients with fungal meningitis may present with ischemic stroke detected on initial imaging scans. A definitive diagnosis should not delay early antifungal treatment.

Epileptic activity associated with Alzheimer disease (AD) deserves increased attention because it has a harmful impact on these patients, can easily go unrecognized and untreated, and may reflect pathogenic processes that also contribute to other aspects of the illness. We report key features of AD-related seizures and epileptiform activity that are instructive for clinical practice and highlight similarities between AD and transgenic animal models of the disease. ⋯ Common clinical features of patients with aMCI- or AD-associated epilepsy at our center included early age at onset of cognitive decline, early incidence of seizures in the disease course, unilateral temporal epileptic foci detected by serial/extended EEG, transient cognitive dysfunction, and good seizure control and tolerability with lamotrigine and levetiracetam. Careful identification and treatment of epilepsy in such patients may improve their clinical course.
