A Kinematic Study of Progressive Micrographia in Parkinson's Disease
This study has investigated the kinematic features of progressive micrographia during a repetitive writing task. Twenty-four PD patients with duration since diagnosis of <10 years and 24 age-matched controls wrote the letter “e” repeatedly. PD patients were studied in defined off states, with scoring of motor function on the Unified Parkinson's Disease Rating Scale Part III. A digital tablet captured x-y coordinates and ink-pen pressure. Customized software recorded the data and offline analysis derived the kinematic features of pen-tip movement. The average size of the first and the last fi...

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

Modifiable Lifestyle Factors and Cognitive Function in Older People: A Cross-Sectional Observational Study
Conclusions: Lifestyle factors, such as physical activity, sleep, and social activity appear to be associated with cognitive function among older people. Physical activity and appropriate durations of sleep and conversation are important for cognitive function. Introduction Dementia is a major public health issue worldwide, with a serious burden for patients, caregivers, and society, as well as substantial economic impacts (1). Although the prevalence of late-life cognitive impairment and dementia are expected to increase in future, effective disease-modifying treatments are currently unavailable. Therefore, unders...

Epidemiology and cerebrovascular events related to cervical and intracranial arteries dissection: the experience of the city of Pisa
This study aims to evaluate the incidence, clinical features, and outcome of cerebrovascular events related to sCAD and spontaneous intracranial arteries dissections (sIAD) in the city of Pisa (Italy). We retrospectively analyzed consecutive patients admitted between December 1997 and June 2015 with a diagnosis of stroke, TIA, or Bernard-Horner syndrome due to acute cervical or intracranial artery dissection. Considering that our hospital collects presumptively all patients hospitalized with sCAD coming from the referral geographical area, data may provide a good approximation to real incidence of sCAD in our population. C...

Decreased CSF Levels of ß-Amyloid in Patients With Cortical Superficial Siderosis
Conclusions: Our results demonstrate that the presence and extent of cSS are associated with reduced CSF ß-amyloid 42 levels. Further studies are needed to investigate the underlying mechanisms of this association. Introduction Cerebral amyloid angiopathy (CAA)—characterized by the deposition of ß-amyloid in the walls of leptomeningeal vessels—is a common cerebral small vessel disease and a major cause of intracerebral hemorrhage in the elderly (1–3). Furthermore, it has become evident that CAA is associated with cognitive impairment (4). Specifically, it has been shown that ...

Mechanical Thrombectomy for Acute Intracranial Carotid Occlusion with Patent Intracranial Arteries
ConclusionOur study showed a  not negligible rate of intracranial carotid artery occlusion with patent intracranial arteries, presenting mostly as severe stroke, with an acceptable rate of 3‑month functional independence. Age, NIHSS at presentation and successful reperfusion were the best independent predictors of outcome.

Long-term outcome of cervical artery dissection
AbstractLong-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 r adiologically diagnosed CeAD were consecutively included in the registry. Baseline demographic and clinical variables, as well as inform...

Has COVID-19 played an unexpected “stroke” on the chain of survival?
The COVID-19 pandemics required several changes in stroke management and it may have influenced some clinical or functional characteristics. We aimed to evaluate the effects of the COVID-19 pandemics on stroke management during the first month of Italy lockdown. In addition, we described the emergency structured pathway adopted by an Italian University Hub Stroke Unit in the cross-border Italy-Slovenia area.

Neurological emergency at the COVID-19 pandemic: report from a referral hospital in Eastern Piedmont, Italy
We described how the flow of neurological emergencies was affected by the pandemic impact.MethodsWe analyzed accesses to the Emergency Department (ED) of the “Maggiore della Carità” Hospital, Piedmont, Italy, during a period of 8 months (COVID time; March to May 2020 and October 2020 to February 2021) and analyzed the admissions to the Neurology Unit and the underlying diagnosis. We also evaluated potential changes in the treatment of acute ischemi c stroke in the same period. These variables were compared with two equivalent periods of time (2019–2020; 2018–2019).ResultsDuring the COVID time, there was a clear-c...

Adult-onset leukodystrophy with vanishing white matter: a case series of 19 patients
ConclusionsAO-LVWM presents varying clinical manifestations at onset, including stroke-like events. WM rarefaction is the most consistent diagnostic clue even in the latest onset cases. Spectroscopy and electrophysiological features are compatible with axon, rather than myelin, damage. Cerebral glucose metabolic abnormalities and retinal alterations can be present. LVWM might also be caused by a digenic inheritance affecting the eIF2B complex.

Why do people search Wikipedia for information on multiple sclerosis?
Conclusion Wikipedia searches do not reliably reflect its actual epidemiology. Celebrities with MS acting as testimonials might effectively increase public knowledge on MS.

Decompressive Craniectomy for Traumatic Brain Injury: Postoperative Cerebral Hemodynamic Evaluation
Conclusion: There is a wide heterogeneity of postoperative cerebral hemodynamic findings among TBI patients who underwent DC, including hemodynamic heterogeneity between their cerebral hemispheres. DC was proved to be effective for the treatment of cerebral oligoemia. Our data support the concept of heterogeneous nature of the pathophysiology of the TBI and suggest that DC as the sole treatment modality is insufficient. Introduction Decompressive craniectomy (DC) may effectively decrease intracranial pressure (ICP) and increase cerebral perfusion pressure (CPP) in traumatic brain injury (TBI) patients with refracto...

Motor Abilities in Adolescents Born Preterm Are Associated With Microstructure of the Corpus Callosum
Conclusions: Impairments in motor abilities are present in preterm born adolescents without major neuromotor impairment and in the absence of focal brain injury. Altered microstructure of the corpus callosum microstructure appears a crucial factor, in particular for movement quality. Introduction Very preterm birth (birth <32 weeks of gestation) is associated with high risk of impaired neurodevelopment. Rates of severe neuromotor impairment, i.e., Cerebral Palsy (CP), are decreasing, in particular in those preterm children born with moderately low and very low birth weight (1). However, in a substantial propo...

Why is Clinical fMRI in a Resting State?
Conclusions Despite some perceived impediments to expanding clinical rs-fMRI use, neuroradiologists were generally enthusiastic about rs-fMRI in research and clinical applications, believing that their current workplace MRI systems are suitable for rs-fMRI acquisition. Many of the concerns associated with using rs-fMRI in clinical contexts are related to: (1) developing better methods for minimizing physiological noise effects, (2) improving methods for detecting the spatial characteristics of clinically-relevant brain processing systems in individual patients, and (3) overcoming remaining standardization, training, and r...
