Background: Accurate prediction of falls in patients with Parkinson's disease (PWP) is crucial for effective prevention efforts. Historically, fall risk models have heavily relied on motor features, overlooking the vital cognitive-motor interplay essential for locomotion.

Methods: Baseline assessments and year-long fall data from the CYClical Lower Extremity Exercise for Parkinson's disease II (CYCLE-II) trial's control group were utilized.

Despite significant progress in understanding the factors influencing cognitive function in Parkinson's disease (PD), there is a notable gap in data representation for the Latinx population. This study aims to evaluate the contributors to and disparities in cognitive performance among Latinx patients with PD. A retrospective analysis was conducted based on cross-sectional data encompassing demographic, environmental, motor, and non-motor disease characteristics from the Latin American Research Consortium on the Genetics of PD (LARGE-PD) and the Parkinson's Progression Markers Initiative (PPMI) cohorts.

Article Synopsis
  • Gilles de la Tourette syndrome (TS) is a neuropsychiatric disorder linked to abnormal brain circuitry and dopamine function, prompting researchers to study neurotransmission changes via TMS-evoked potentials (TEPs).
  • The study involved 33 TS patients and 18 healthy controls, evaluating symptoms like tics and anxiety using various assessments and measuring TEPs in key brain regions.
  • Results showed delayed and lower TEP responses in TS patients, particularly in the motor and prefrontal cortices, which correlated with tic severity and anxiety, suggesting these patterns may help understand TS's underlying mechanisms.

Introduction: The first-line treatment for Parkinson's disease (PD) involves dopamine-replacement therapies; however, significant variability exists in patient responses. Pharmacogenomics has been explored as a potential approach to understanding and predicting treatment outcomes. This review aims to evaluate the current state of knowledge regarding the role of pharmacogenomics in PD, focusing on identifying challenges and proposing future directions.

Alpha-synuclein (aSyn) aggregates in the central nervous system are the main pathological hallmark of Parkinson's disease (PD). ASyn aggregates have also been detected in many peripheral tissues, including the skin, thus providing a novel and accessible target tissue for the detection of PD pathology. Still, a well-established validated quantitative biomarker for early diagnosis of PD that also allows for tracking of disease progression remains lacking.

Background: Advanced Parkinson's disease (PD) can be treated with Levodopa-Carbidopa Intestinal Gel (LCIG).

Objective: To compare descriptive data of LCIG treatment in GBA1-PD and LRRK2-PD.

Methods: This multicenter retrospective study compared clinical data obtained from electronic medical records of PD patients treated with LCIG.

The landscape of medical care has rapidly evolved with technological advancements, particularly through the widespread adoption of virtual appointments catalyzed by the COVID-19 pandemic. This shift has transcended geographical barriers, enhancing access for underserved populations and those with disabilities to specialized healthcare providers. A notable development stemming from this trend is the emergence of virtual shared medical appointments (VSMAs), which integrate group-based education with telemedicine technology.

Genetic workup is becoming increasingly common in the clinical assessment of neurological disorders. We evaluated its yield among middle-aged and elderly neurological patients, in a real-world context. This retrospective study included 368 consecutive Israeli patients aged 50 years and older (202 [54.

Alexander disease (AxD) is a rare autosomal dominant leukodystrophy caused by heterozygous mutations in the glial fibrillary acid protein (GFAP) gene. The age of symptoms onset ranges from infancy to adulthood, with variable clinical and radiological manifestations. Adult-onset AxD manifests as a chronic and progressive condition, characterized by bulbar, motor, cerebellar, and other clinical signs and symptoms.

Background: While cannabis-based medicine is being commonly used in patients with movement disorders, there is a scarcity of publications regarding the effect of cannabis on dystonia. We aimed to describe medical cannabis use in patients with dystonia and related pain.

Methods: We employed a structured interview to obtain data on the cannabis treatment regimen, perception of effectiveness and side effect profile.

Background: Whole-plant medical cannabis (MC) products are widely used for controlling symptoms associated with Parkinson's disease (PD). Despite its widespread use, few studies have investigated the long-term impact of MC on the progression of PD or its safety profile. This study examined the effects of MC on PD in a real-life setting.

Medical cannabis (MC) is widely used in clinical practice to treat Gilles de la Tourette syndrome (GTS). However, legislation, multiple modes of administration, and inconsistent plant preparations have limited trials to assess its benefits and long-term safety. For the past decade, licensed MC has been authorized in Israel for use in resistant GTS.

Objectives: Ankylosing spondylitis (AS) is a chronic progressive and debilitating form of arthritis with associated extra-articular features including uveitis, intestinal and lung apical inflammation and psoriasis. Putative associations between AS and neurologic disorders has been relatively overlooked. The purpose of this study is to assess the link between AS and major neurologic disorders and whether treatment with Tumor-Necrosis-Factor inhibitors (TNFi) has an impact on that association.

Objectives: Assessing the effectiveness and tolerability of medical cannabis (MC) treatment on Gilles de la Tourette syndrome (GTS) patients.

Methods: We report on an open-label, prospective study on the effect of MC on adult GTS patients. MC mode of use was decided by the treating neurologist and the patient.

Objectives: We aimed to estimate the frequency of epileptic seizures (ES) and psychogenic nonepileptic seizures (PNES) with atypical duration in our epilepsy monitoring unit (EMU), in order to raise awareness of atypical durations of both types of events.

Materials & Methods: We retrospectively reviewed all consecutive video-electroencephalogram (vEEG) recordings in our medical center's EMU from January 2013 to December 2017 and identified patients with seizures with atypical duration. Short PNES were defined as those lasting fewer than 2 min and long ES as those lasting for more than 5 min.

Background: The Unified Dyskinesia Rating Scale (UDysRS) is a well-established tool for producing comprehensive assessments of severity and disability associated with dyskinesia in patients with Parkinson's disease (PD). The scale was originally developed in English, and a broad international effort has been undertaken to develop and validate versions in additional languages. Our aim was to validate the Hebrew version of the UDysRS.

Objectives: We aimed to explore the diagnostic value, clinical correlates and electroencephalographic features of FIRDA (Frontal intermittent rhythmic delta activity).

Materials And Methods: We retrospectively reviewed reports from EEG studies done in adults at our tertiary center between January 2015 and May 2018. For cases demonstrating FIRDA, medical files were reviewed and each case was given a diagnostic category.

Evidence of epigenetics' role in pain response is accumulating in recent years. Tightly regulated epigenetic alterations on DNA and histones in the sensory circuit shape the physiological response to injury. Altering those epigenetic processes hinders therapeutic potential in pain.

For the last 20 years the classic treatment for relapsing remitting multiple sclerosis was based on injectable disease-modifying drugs, interferon-β and glatiramer acetate (copaxone). Currently, new disease-modifying drugs have been added to the clinician's arsenal with similar and even improved efficacy and safety profiles. Some of these drugs are given orally and are recommended as first line treatment.
