Encephalopathy as a prognostic factor in adults with acute disseminated encephalomyelitis following COVID-19.

Numerous reports support the possible occurrence of acute disseminated encephalomyelitis (ADEM) following COVID-19. Herein, we report a case of ADEM in a 53-year-old man 2 weeks after SARS-CoV-2 infection. We reviewed the reports of adult cases of ADEM and its variant acute necrotizing hemorrhagic leukoencephalitis (ANHLE) to check for possible prognostic factors and clinical/epidemiological peculiarities.

Movement disorders in emergency settings: a prospective study.

Introduction: Acute movement disorders (MD) are etiologically heterogeneous entities. Since studies on the relative frequency of different MD and their underlying diseases are limited, we performed a prospective study to investigate the spectrum of various MD and their causes in patients presenting with acute MD in an emergency room (ER) setting.

Objective: To describe the spectrum and outcomes of acute MD in a prospective cohort and to guide its management.

Imaging of the dopamine transporter predicts pattern of disease progression and response to levodopa in patients with schizophrenia and parkinsonism: a 2-year follow-up multicenter study.

Similarly to subjects with degenerative parkinsonism, (123)I-FP-CIT SPECT has been reported either normal or abnormal in patients with drug-induced parkinsonism (DIP), challenging the notion that parkinsonism might be entirely due to post-synaptic D2-receptors blockade by antipsychotic drugs. In a previous multicenter cross-sectional study conducted on a large sample of patients with schizophrenia, we identified 97 patients who developed parkinsonism with a similar bi-modal distribution of DAT-SPECT. In this longitudinal study, we reported clinical and imaging features associated with progression of motor disability over 2-year follow-up in 60 out of those 97 patients with schizophrenia and parkinsonism who underwent (123)I-FP-CIT SPECT at baseline evaluation (normal SPECT=33; abnormal SPECT=27).

[¹²³I]FP-CIT single photon emission computed tomography findings in drug-induced Parkinsonism.

Drug-induced parkinsonism (DIP) in patients treated with antipsychotic drugs is considered a form of post-synaptic parkinsonism, caused by D2-receptor blockade. Recent studies, however, carried out on small and heterogeneous patient samples, have shown that DIP may be associated with [(123)I]FP-CIT single photon emission computed tomography (SPECT) abnormalities, which are markers of dopamine nigrostriatal terminal defect. In the present study, outpatients fulfilling the DSM-IV criteria for schizophrenia and treated with antipsychotics for at least 6 months, were enrolled in order to estimate the prevalence of DIP and, among patients with DIP, the prevalence of [(123)I]FP-CIT SPECT abnormalities.

Clinical experiences with levodopa methylester (melevodopa) in patients with Parkinson disease experiencing motor fluctuations: an open-label observational study.

Introduction: Slow gastric emptying decreasing levodopa (LD) bioavailability contributes to motor fluctuations in Parkinson disease (PD). Melevodopa (LD methylester), ensuring rapid duodenal absorption, has been proposed as rescue therapy for afternoon off periods.

Objective: To assess daily motor fluctuations by multiple administrations of Sirio (Chiesi Farmaceutici SpA, Parma, Italy) (melevodopa/carbidopa) in PD patients.
