The Rush Video-Based Tic Rating Scale-Revised: A Practice-Oriented Revision.

Background: The Modified Rush Video-Based Tic Rating Scale (MRVS) is the most widely used video-based scale for assessing tic severity in patients with Tourette syndrome (TS). However, shortcomings of the MRVS, including a lack of clear instructions, a time-consuming recording procedure, and weak correlations with the gold standard for tic assessment, the Yale Global Tic Severity Scale-Total Tic Score (YGTSS-TTS), limits its use in research settings, although video assessments are generally considered objective, reliable, and time-saving measurements.

Objectives: We aimed to revise the MRVS (MRVS-R) to simplify and standardize the assessment procedure and improve the correlation with the YGTSS-TTS.

Association of vitamin K with cognitive decline and neuropathology in community-dwelling older persons.

Higher vitamin K intakes have been associated with better cognitive function, suggestive of a vitamin K mechanistic effect or simply reflective of a healthy diet. To test the hypothesis that brain vitamin K is linked to cognitive decline and dementia, vitamin K concentrations were measured in four brain regions, and their associations with cognitive and neuropathological outcomes were estimated in 325 decedents of the Rush Memory and Aging Project. Menaquinone-4 (MK4) was the main vitamin K form in the brain regions evaluated.

The Burden of Movement Disorders in Cameroon: A Rural and Urban-Based Inpatient/Outpatient Study.

Background: Because of rapid demographic changes, the prevalence of movement disorders (MDs) is expected to increase in Africa. The objective of this study was to estimate the prevalence of MDs in an inpatient/outpatient-based study of rural and urban health care centers in Cameroon.

Methods: In this retrospective medical chart review, the inpatient/outpatients settings covered an urban population (3,000,000) and a rural population (380,276).

The Corpus Callosum Splenium Sign in Fragile X-Associated Tremor Ataxia Syndrome.

Background: Hyperintensities in the splenium of the corpus callosum (CCS) have been proposed as a radiographic diagnostic criterion for fragile X-associated tremor ataxia syndrome (FXTAS).

Methods: Magnetic resonance images from patients with FXTAS and from nonpremutation carriers with movement disorders were viewed by a radiologist who was blinded to gene status, and radiographic criteria for FXTAS were scored. Phenotypic data used for diagnosis of FXTAS also were collected.

Clinimetric Analysis of the Motor Section of the Progressive Supranuclear Palsy Rating Scale: Reliability and Factor Analysis.

Introduction: PSP is a rare degenerative disorder associated with significant morbidity. Recently, investigations of the etiology and treatment of PSP have been initiated. The aim of the present study was to validate the motor domain of the Progressive Supranuclear Palsy Rating Scale (PSPRS) as part of a larger epidemiological study.

The Neuropsychiatric and Motor Profile of -Associated Parkinson's Disease: A Review.

Background: Cognitive and motor decline, along with psychiatric symptoms, have a major impact on independence, nursing home admission, caregiver burden, and mortality in Parkinson's disease (PD). The single most common genetic risk factor for developing PD is a mutation in the () gene.

Methods: This work is a literature review regarding "GBA" and "Parkinson's disease" as conducted by PubMed search.
