Alon Kalron, Gilles Allali
Our goal was to identify the specific contribution of fear of falling (FoF) and falls with quantitative gait impairments and cognition capabilities in multiple sclerosis (MS) patients. Patients were separated into four individual subgroups as to the presence of FoF and falls (i.e., fearless/non-fallers, fearless/fallers, FoF/non-fallers and FoF/fallers). The Falls Efficacy Scale International questionnaire was used to assess the level of concern of falling. Participants were defined as "fallers" and "non-fallers" based on their fall history...

OBJECTIVE: We wanted to identify differences in grey and white matter in essential tremor patients compared to controls in the non-motor domain, using the example of impaired verbal fluency. BACKGROUND: A disturbance of verbal fluency in essential tremor patients compared to healthy controls is behaviorally well described. METHODS: Voxel-based morphometry and tract-based spatial statistics were used to analyze structural differences in grey and white matter in 19 essential tremor patients compared to 23 age- and gender-matched controls...

GLE1 encodes a protein important for mRNA export and appears to play roles in translation initiation and termination as well. Pathogenic variants in GLE1 mutations have been associated with lethal contracture syndrome (LCCS1) and Lethal Arthrogryposis with Anterior Horn Cell Disease (LAAHD); phenotypes reported in individuals include fetal akinesia and a severe form of motor neuron disease, typically presenting with prenatal symptoms and perinatal lethality. In this paper, we identified bi-allelic missense mutations in GLE1 by trio whole exome sequencing (WES) in an individual affected with congenital motor weakness and contractures as well as feeding and respiratory difficulties...

Due to the increasing life expectancy and a higher incidence in the elderly, the number of elderly patients with idiopathic Parkinson's disease will increase in the coming years. Since the burden of comorbidities is higher and medication side effects are more likely in the elderly, particularly in the light of frequently occurring polypharmacy, increased awareness and therapeutic knowledge is necessary. Besides the therapy of motor symptoms, non-motor symptoms, e. g. neuropsychiatric and autonomic disorders, also need to be addressed as they can also greatly impair the quality of life...

The benefit of deep brain stimulation (DBS) in controlling the motor symptoms of Parkinson's disease is well established, however, the impact on the non-motor symptoms (NMS) remains to be elucidated, although the growing investigative efforts are promising. This article reviews the reported data and considers the level of evidence available with regard to the effect of DBS on NMS total burden and on the cognitive, neuropsychiatric, sleep, pain, dysautonomic, and weight domains. Multiple case series suggest that DBS improves the burden of NMS by reducing prevalence, intensity, and non-motor fluctuations...

Gilles de la Tourette syndrome is a chronic neuropsychiatric movement disease with combined motor tics and at least one vocal tic for a minimum period of 1 year. It typically begins in the childhood (under 18 years of age).Most of the patients with Tourette syndrome have comorbidities, which often impair their quality of life more than the tics themselves.There are reported abnormalities in the cortico-striato-thalamo-cortical regions as well as in the neurotransmission of dopamine and other neurotransmission systems...

Parkinson's disease (PD) is the second most common neurodegenerative disorder and has both unknown etiology and non-curative therapeutic options. Patients begin to present the classic motor symptoms of PD-tremor at rest, bradykinesia and rigidity-once 50-70% of the dopaminergic neurons of the nigrostriatal pathway have degenerated. As a consequence of this, it is difficult to investigate the early-stage events of disease pathogenesis. In vitro experimental models are used extensively in PD research because they present a controlled environment that enables the direct investigation of the early molecular mechanisms that are potentially involved with dopaminergic degeneration, as well as for the screening of potential therapeutic drugs...

Cerebral malaria (CM) is a common cause of death and disability among children in sub-Saharan Africa. Many prior studies of neuropsychiatric morbidity have been limited by a cross-sectional design or a short duration of follow-up. Most have included subjects who may have presented with coma due to a disease process other than CM. No studies have assessed the relationship between magnetic resonance imaging (MRI) findings and long-term outcomes. The Cognitive Outcomes and Psychiatric symptoms of retinopathy-positive CM (COPS) cohort is the first large (N = 221) prospectively recruited cohort of stringently defined cases of CM and hospital-based, age-matched, non-CM controls in whom cognitive and psychiatric outcomes are assessed with standardized measures semi-annually for up to 5 years...

INTRODUCTION: A latent nigrostriatal deficit and its possible clinical consequences in asymptomatic heterozygous Parkin and PINK1 mutation carriers (AMC) have been a matter of investigation in recent years. Notably, mild Parkinsonian signs in heterozygous mutation carriers can be so subtle that they may be missed if not specifically investigated. METHODS: We studied 15 heterozygous Parkin and PINK1 AMC and 18 age- and sex-matched mutation-negative controls using a standardized video, instructing the probands to perform relevant parts of the UPDRS III to investigate fine motor movements at baseline and after first-time L-Dopa administration...

Patients with Parkinson's disease (PD) may develop a wide spectrum of non-motor symptoms during the course of illness. Psychosis is one such commonly observed non-motor symptoms of PD. Although several studies based on neuroimaging, genetics, retinal imaging, and neuropsychological evaluations have explored the pathogenesis of psychosis in PD; exact neural correlates are yet to be understood. Identification of factors related to psychosis in PD is important, as psychosis has been reported to be associated with higher rates of mortality, caregiver distress, and nursing home placements...

AIM: To develop a new scoring system, nutech functional scores (NFS) for assessing the patients with spinal cord injury (SCI). METHODS: The conventional scale, American Spinal Injury Association's (ASIA) impairment scale is a measure which precisely describes the severity of the SCI. However, it has various limitations which lead to incomplete assessment of SCI patients. We have developed a 63 point scoring system, i.e., NFS for patients suffering with SCI. A list of symptoms either common or rare that were found to be associated with SCI was recorded for each patient...

Parkinson's disease (PD) is a neurodegenerative multisystem disorder characterized by progressive motor symptoms such as bradykinesia, tremor and muscle rigidity. Over the course of the disease, numerous non-motor symptoms, sometimes preceding the onset of motor symptoms, significantly impair patients' quality of life. The significance of non-motor symptoms may outweigh the burden through progressive motor incapacity, especially in later stages of the disease. The advanced stage of the disease is characterized by motor complications such as fluctuations and dyskinesias induced by the long-term application of levodopa therapy...

Parkinson's disease (PD) is one of common neurodegenerative diseases, which shows motor symptoms including tremor, bradykinesia, rigidity and postural instability. It also involves non-motor symptoms such as cognitive impairment, mental manifestation, autonomic disorder and sensory disturbance. Although treatments to improve the motor disability in PD are being assessed at present, the main challenge remains that is the development of neuroprotective or disease-modifying treatments. Therefore, it is desirable to find approaches that can inhibit the progression of dopaminergic neurodegeneration...
