BACKGROUND: Idiopathic normal-pressure hydrocephalus (iNPH) is defined by ventriculomegaly, cognitive decline, urinary incontinence and gait problems. Vascular risk factors (VRF) are associated with iNPH but obstructive sleep apnea (OSA) -a well-known independent VRF- is seldom mentioned. METHODS: We investigated the presence of sleep-disordered breathing in a prospective cohort of 31 consecutive unselected patients with iNPH using sleep questionnaires and nocturnal polysomnography (PSG)...

BACKGROUND AND IMPORTANCE: The therapeutic approach for cerebellar damages heavily relies on neurorehabilitation since there are no medications that may improve clinical symptoms mainly those related to cognitive dysfunctions. Nevertheless, neurorehabilitation programs tailored to cerebellar damages have never been validated. Here we describe a new rehabilitation approach based on cooking training (CT). The idea that cooking may stimulate cerebellar activity relies on previous evidence demonstrating the beneficial effect on the executive functions as well as in promoting neural plasticity within the cerebellum...

BACKGROUND: Dynamic balance keeps the vertical projection of the center of mass within the base of support while walking. Dynamic balance tests are used to predict the risks of falls and eventual falls. The psychometric properties of most dynamic balance tests are unsatisfactory and do not comprise an actual loss of balance while walking. OBJECTIVES: Using beam walking distance as a measure of dynamic balance, the BEAM consortium will determine the psychometric properties, lifespan and patient reference values, the relationship with selected "dynamic balance tests," and the accuracy of beam walking distance to predict falls...

To the clinical cognitive impairment following intracerebral hemorrhage, comprehensive neuropsychological assessments and efficacious interventions have rarely been conducted. Lithium chloride, a classical treatment for bipolar disorder, has shown neuroprotective effects through glycogen synthase kinase-3β inhibition in a variety of central nervous system diseases, including stroke. Since neurons that contain glutamate play crucial roles in psychological functions, such as learning and memory, the glutamate-mediated excitotoxicity and consequent neuronal death and cognitive impairment in hippocampus may co-determine the clinical course of intracerebral hemorrhage...

OBJECTIVE: To examine whether the Montreal Cognitive Assessment (MoCA) administered within 7 days after stroke predicts long-term cognitive impairment, functional impairment, and mortality. METHODS: MoCA was administered to 274 patients from 2 prospective hospital-based cohort studies in Germany (n = 125) and France (n = 149). Cognitive and functional outcomes were assessed at 6, 12, and 36 months after stroke by comprehensive neuropsychological testing, the Clinical Dementia Rating (CDR) scale, the modified Rankin Scale (mRS), and Instrumental Activities of Daily Living (IADL) and analyzed with generalized estimating equations...

Efficient blood supply to the brain is of paramount importance to its normal functioning and improper blood flow can result in potentially devastating neurological consequences. Cerebral blood flow in response to neural activity is intrinsically regulated by a complex interplay between various cell types within the brain in a relationship termed neurovascular coupling. The breakdown of neurovascular coupling is evident across a wide variety of both neurological and psychiatric disorders including Alzheimer's disease...

This article highlights the major reflections of ancient Greek mythology in modern neuroscience. An analysis of ancient Greek texts and medical literature using the MeSH term mythology was performed to identify mythological references pertaining to neuroscience. The findings are discussed in relation to etymology, early conceptualization of the nervous system structure and function, incipient characterization of neuropsychiatric disease, and philosophical stance to the practice of medicine in ancient Greece...

Brain health plays a central role in wellbeing and in the management of chronic diseases. Stroke and dementia pose the two greatest threats to brain health, but recent developments suggest the possibility that preventing stroke may also prevent some dementias: 1. A large population study showed a 32% decrease in the incidence of stroke and a concomitant 7% reduction in the incidence of dementia; 2. Treatment of atrial fibrillation resulted not only in stroke reduction, but a 48% decrease in dementia; 3. A hypothesis free analyses has shown that the first phase of Alzheimer disease involves vascular dysregulation, opening the door to new therapeutic approaches; 4...

BACKGROUND: Subcortical small vessel disease and vascular risk factors are associated with motor and cognitive impairment. In this study we examined the relationship between these factors and the severity of motor impairment and dementia in pathologically-confirmed Parkinson's disease (PD). METHODS: The extent and severity of small vessel disease (SVD) was assessed pathologically in 77 patients with PD. The severity of motor impairment was determined using a cumulative index derived from longitudinal measures of Hoehn and Yahr score...

Background: The majority of stroke patients are inactive outside formal therapy sessions. Tailored activity feedback via a smartwatch has the potential to increase inpatient activity. The aim of the study was to identify the challenges and support needed by ward staff and researchers and to examine the feasibility of conducting a randomised controlled trial (RCT) using smartwatch activity monitors in research-naive rehabilitation wards. Objectives (Phase 1 and 2) were to report any challenges and support needed and determine the recruitment and retention rate, completion of outcome measures, smartwatch adherence rate, (Phase 2 only) readiness to randomise, adherence to protocol (intervention fidelity) and potential for effect...

OBJECTIVE: Despite the benefits of being active for people with mild cognitive impairment (MCI) on cognition and the acknowledgement that MCI is a critical period for intervening to prevent dementia, little is known about the actual sedentary levels in people with MCI. This study investigates correlates of sedentary behavior (SB) in people with MCI. DESIGN: This was a cross-sectional study. SETTING: Data from the World Health Organization's Study on Global Ageing and Adult Health were analyzed...

BACKGROUND: A body of empirical work demonstrates that wide fluctuations in a person's blood pressure across consecutive measures, known as blood pressure variability (BPV), hold prognostic value to predict stroke and transient ischemic attack. However, the magnitude of association between BPV and other neurological outcomes remains less clear. This systematic review aims to pool together data regarding BPV with respect to incident dementia, cognitive impairment, and cognitive function...

Childhood arterial ischemic stroke often involves basal ganglia and thalamus but little is known about neuropsychological outcomes in this group. We examined intellectual ability, academics, attention, executive function, and psychological diagnoses in children and adolescents (6-20 years of age) with childhood stroke involving the basal ganglia (n = 32) or thalamus (n = 12). Intellectual ability was age-appropriate but working memory was significantly lower than expected. Compared to the normative mean, the stroke group exhibited significantly weaker performance in reading comprehension, math fluency, attention, and greater challenges with executive function...

Cerebral cortical microinfarct (CMI) is common in patients with dementia and cognitive decline. Emerging studies reported that intestinal dysfunction influenced the outcome of ischemic stroke and that vagus nerve stimulation (VNS) protected against ischemic stroke. However, the effects of intestinal dysfunction and VNS on CMI are not clear. Therefore, we examined the influence of colitis and VNS on CMI and the mechanisms of VNS attenuating CMI in mice with colitis. CMI was induced using a two-photon laser. Colitis was induced using oral dextran sodium sulfate (DSS)...
