Implementation of Mobile Health Technologies in Clinical Trials of Movement Disorders: Underutilized Potential.

Mobile health technologies (mHealth) are patient-worn or portable devices aimed at increasing the granularity and relevance of clinical measurements. The implementation of mHealth has the potential to decrease sample size, duration, and cost of clinical trials. We performed a review of the ClinicalTrials.

Effortful speech with distortion of prosody following SARS-CoV-2 infection.

Coronavirus disease 2019 (COVID-19) infection has the potential for targeting the central nervous system, and several neurological symptoms have been reported in patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We describe a 48-year-old Caucasian woman with SARS-CoV-2 infection followed by the onset of word finding difficulties, effortful speech along with prosody distortion, in the context of spared semantic and syntactic abilities. The clinical picture, perceived as foreign accent syndrome (FAS), was not associated with structural and functional imaging changes or neurophysiological assessment abnormalities.

The combined effect of amyloid-β and tau biomarkers on brain atrophy in dementia with Lewy bodies.

Background: Alzheimer's disease (AD)-related pathology is frequently found in patients with dementia with Lewy bodies (DLB). However, it is unknown how amyloid-β and tau-related pathologies influence neurodegeneration in DLB. Understanding the mechanisms underlying brain atrophy in DLB can improve our knowledge about disease progression, differential diagnosis, drug development and testing of anti-amyloid and anti-tau therapies in DLB.

Improving the care of older patients during the COVID-19 pandemic.

The SARS-CoV-2 pandemic has led to a dramatic crisis of Health Care Systems worldwide, and older people have been among the most disadvantaged. Specific recommendations and reports have been released both at International and National level, regarding the diagnosis and management of COVID-19 in the elderly. However, little has been proposed for an appropriate response to older, frail and multimorbid patients in different settings of care (acute care units, long term care facilities, nursing homes and primary care) and for the management of geriatric syndromes (i.

The care and keeping of clinicians in quality improvement.

Objective: Although frontline clinicians are crucial in implementing and spreading innovations, their engagement in quality improvement remains suboptimal. Our goal was to identify facilitators and barriers to the development and engagement of clinicians in quality improvement.

Design: A 25-item questionnaire informed by theoretical frameworks was developed, tested and disseminated by email.

The Use of Social Media and Digital Devices Among Italian Neurologists.

Digital devices and online social networks are changing clinical practice. In this study, we explored attitudes, awareness, opinions, and experiences of neurologists toward social media and digital devices. Each member of the Italian Society of Neurology (SIN) participated in an online survey (January to May 2018) to collect information on their attitude toward digital health.

Benign versus malignant Parkinson disease: the unexpected silver lining of motor complications.

Objective: We sought to evaluate demographic, clinical, and habits/occupational variables between phenotypic extremes in Parkinson's disease (PD).

Methods: Databases from nine movement disorders centers across seven countries were retrospectively searched for subjects meeting criteria for very slowly progressive, benign, PD (bPD) and rapidly progressive, malignant, PD (mPD). bPD was defined as Hoehn and Yahr (H&Y) stage ≤ 3, normal cognitive function, and Schwab and England (S&E) score ≥ 70 after ≥ 20 years of PD (≥ 10 years if older than 60 at PD onset); mPD as H&Y > 3, S&E score < 70, and cognitive impairment within 10 years from PD onset.

Cortical Inhibitory Imbalance in Functional Paralysis.

Background: Functional neurological disorders are characterized by neurological symptoms that have no identifiable pathology and little is known about their underlying pathophysiology.

Objectives: To analyze motor cortex excitability and intracortical inhibitory and excitatory circuits' imbalance in patients with flaccid functional weakness.

Methods: Twenty-one consecutive patients with acute onset of flaccid functional weakness were recruited.

Anterior EEG slowing in dementia with Lewy bodies: a multicenter European cohort study.

Electroencephalography (EEG) slowing with prealpha dominant frequency (DF) in posterior derivations is a biomarker for dementia with Lewy bodies (DLB) diagnosis, in contrast with Alzheimer's disease (AD). However, an intrasubject re-evaluation of the original data, which contributed to the identification of EEG DLB biomarker, showed that DF was slower in anterior than posterior derivations. We suppose this anterior-posterior gradient of DF slowing could arise in DLB from a thalamocortical dysrhythmia, differently involving the anterior and posterior cortical areas, and correlating with cognitive impairment (Mini-Mental State Examination).

Expanding the role of education in frontotemporal dementia: a functional dynamic connectivity (the chronnectome) study.

In the present study, we aim at investigating whether education modulates dynamical properties of time-varying whole-brain network connectivity (the chronnectome) in frontotemporal dementia (FTD) at a given level of symptom severity. Dynamic connectivity parameters were evaluated in 128 patients with FTD using independent component analysis, sliding-time window correlation, and k-means approach to resting state-magnetic resonance imaging data. We evaluated the relationship between education, a proxy measure of cognitive reserve, and 4 indexes of metastate dynamic connectivity: (1) the number of distinct metastates a patient passes through, (2) the number of switches from one metastate to another, (3) the span of the realized metastates, and (4) the total distance traveled in the state space.

Clinical characteristics and outcomes of inpatients with neurologic disease and COVID-19 in Brescia, Lombardy, Italy.

Objective: To report clinical and laboratory characteristics, treatment, and clinical outcomes of patients admitted for neurologic diseases with and without coronavirus disease 2019 (COVID-19).

Methods: In this retrospective, single-center cohort study, we included all adult inpatients with confirmed COVID-19 admitted to a neuro-COVID unit beginning February 21, 2020, who had been discharged or died by April 5, 2020. Demographic, clinical, treatment, and laboratory data were extracted from medical records and compared (false discovery rate corrected) to those of neurologic patients without COVID-19 admitted in the same period.

Imaging of Neurologic Disease in Hospitalized Patients with COVID-19: An Italian Multicenter Retrospective Observational Study.

Of 725 consecutive hospitalized patients with coronavirus disease 2019, 108 (15%) had acute neurologic symptoms necessitating neurologic imaging.

Neurological manifestations associated with COVID-19: a review and a call for action.

While the epidemic of Coronavirus disease 2019 (COVID-19) continues to spread globally, more and more evidences are collected about the presence of neurological manifestations and symptoms associated with it. A systematic review has been performed of papers published until 5 April 2020. 29 papers related to neurological manifestations associated with COVID-19 were examined.

An Italian multicenter retrospective-prospective observational study on neurological manifestations of COVID-19 (NEUROCOVID).

Neurological manifestations of COVID-19 have been described in both single case reports and retrospective scanty case series. They may be linked to the potential neurotropism of the SARS-COV-2 virus, as previously demonstrated for other coronaviruses. We report here the description of a multicenter retrospective-prospective observational study promoted by the Italian Society of Neurology (SIN), involving the Italian Neurological Departments, who will consecutively recruit patients with neurological symptoms and/or signs, occurred at the onset or as a complication of COVID-19.

Steroid-Responsive Encephalitis in Coronavirus Disease 2019.

Coronavirus disease 2019 (COVID-19) infection has the potential for targeting the central nervous system, and several neurological symptoms have been described in patients with severe respiratory distress. Here, we described the case of a 60-year-old patient with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection but only mild respiratory abnormalities who developed an akinetic mutism attributable to encephalitis. Magnetic resonance imaging was negative, whereas electroencephalography showed generalized theta slowing.

Long-term outcome of cervical artery dissection : IPSYS CeAD: study protocol, rationale, and baseline data of an Italian multicenter research collaboration.

Long-term consequences of cervical artery dissection (CeAD), a major cause of ischemic stroke in young people, have been poorly investigated. The Italian Project on Stroke at Young Age - Cervical Artery Dissection (IPSYS CeAD) project is a multicenter, hospital-based, consecutively recruiting, observational, cohort study aimed to address clinically important questions about long-term outcome of CeAD patients, which are not covered by other large-scale registries. Patients with radiologically diagnosed CeAD were consecutively included in the registry.

Enhanced dynamic functional connectivity (whole-brain chronnectome) in chess experts.

Multidisciplinary approaches have demonstrated that the brain is potentially modulated by the long-term acquisition and practice of specific skills. Chess playing can be considered a paradigm for shaping brain function, with complex interactions among brain networks possibly enhancing cognitive processing. Dynamic network analysis based on resting-state magnetic resonance imaging (rs-fMRI) can be useful to explore the effect of chess playing on whole-brain fluidity/dynamism (the chronnectome).

Serum neuronal exosomes predict and differentiate Parkinson's disease from atypical parkinsonism.

Objective: Parkinson's disease is characterised neuropathologically by α-synuclein aggregation. Currently, there is no blood test to predict the underlying pathology or distinguish Parkinson's from atypical parkinsonian syndromes. We assessed the clinical utility of serum neuronal exosomes as biomarkers across the spectrum of Parkinson's disease, multiple system atrophy and other proteinopathies.

Pathophysiological Mechanisms and Potential Therapeutic Targets in Cerebral Autosomal Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalopathy (CADASIL).

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), is a hereditary small-vessels angiopathy caused by mutations in the NOTCH 3 gene, located on chromosome 19, usually affecting middle-ages adults, whose clinical manifestations include migraine with aura, recurrent strokes, mood disorders, and cognitive impairment leading to dementia and disability. In this review, we provide an overview of the current knowledge on the pathogenic mechanisms underlying the disease, focus on the corresponding therapeutic targets, and discuss the most promising treatment strategies currently under investigations. The hypothesis that CADASIL is an appropriate model to explore the pathogenesis of sporadic cerebral small vessel disease is also reviewed.

Subarachnoid Extension Predicts Lobar Intracerebral Hemorrhage Expansion.

Background and Purpose- We investigated whether subarachnoid extension (SAHE) of intracerebral hemorrhage (ICH) is associated with hematoma expansion (HE). Methods- Retrospective analysis of patients with primary spontaneous ICH admitted at 3 academic hospitals in Italy. The study population was divided into a development and a replication cohort.

In-vivo signatures of neurodegeneration in isolated rapid eye movement sleep behaviour disorder.

Background And Purpose: Isolated rapid eye movement sleep behaviour disorder (iRBD) is a parasomnia, recently recognized as a risk factor for progression to Parkinson's disease, dementia with Lewy body and multiple system atrophy. Biomarker studies in iRBD are relevant due to lack of evidence in this condition. The identification of biomarkers able to predict progression to synucleinopathy diseases is critical for iRBD.

Motor, cognitive and mobility deficits in 1000 geriatric patients: protocol of a quantitative observational study before and after routine clinical geriatric treatment - the ComOn-study.

Background: Motor and cognitive deficits and consequently mobility problems are common in geriatric patients. The currently available methods for diagnosis and for the evaluation of treatment in this vulnerable cohort are limited. The aims of the ComOn (COgnitive and Motor interactions in the Older populatioN) study are (i) to define quantitative markers with clinical relevance for motor and cognitive deficits, (ii) to investigate the interaction between both motor and cognitive deficits and (iii) to assess health status as well as treatment outcome of 1000 geriatric inpatients in hospitals of Kiel (Germany), Brescia (Italy), Porto (Portugal), Curitiba (Brazil) and Bochum (Germany).
