BACKGROUND: Dementias are fairly slowly progressive degenerative diseases of brain for which treatment options are very less and carry a lot of burden on family and society. A small percentage of them are rapidly progressive and mostly carry a different course outcome. However, there are no definite criteria other than the time line for these patients. AIMS: The aim of this was to identify and categorize the causes and course of rapidly progressive dementias seen in our center...

INTRODUCTION: The Mini-Cog is a simple and short test that identifies cognitive impairment. Its detection helps provide an early dementia diagnosis, rapid access to treatments, and even delay or reversion. MATERIALS AND METHODS: This multicenter, observational, descriptive, and cross-sectional study included 214 patients. Patients enrolled in this study were community dwellers aged ≥55-year-old, without prior diagnosis of cognitive impairment or dementia, with adequate hearing and vision functions...

BACKGROUND: Three archetypal trajectories of physical decline have been identified: a short period of rapid decline; long-term limitations with intermittent acute periods; and a prolonged gradual decline. An understanding of illness trajectories can help clarify the evolving needs of people with progressive conditions, and inform the development of palliative care services to meet their needs. Many frail older people live and die in care homes; the present study is the first to explore the illness trajectories of residents in care home settings...

Parkinson's disease dementia (PDD) and dementia with Lewy bodies (DLB) are relentlessly progressive neurodegenerative disorders that are likely to represent two ends of a disease spectrum. It is well established that both are characterised pathologically by widespread cortical Lewy body deposition. However, until recently, the pathophysiological mechanisms leading to neuronal damage were not known. It was also not understood why some cells are particularly vulnerable in PDD/DLB, nor why some individuals show more aggressive and rapid dementia than others...

Informatics increases the yield from neuroscience due to improved data. Data sharing and accessibility enable joint efforts between different research groups, as well as replication studies, pivotal for progress in the field. Research data archiving solutions are evolving rapidly to address these necessities, however, distributed data integration is still difficult because of the need of explicit agreements for disparate data models. To address these problems, ontologies are widely used in biomedical research to obtain common vocabularies and logical descriptions, but its application may suffer from scalability issues, domain bias, and loss of low-level data access...

BACKGROUND: Amyloid pathology in subjects with mild cognitive impairment (MCI) is an important risk factor for progression to dementia due to Alzheimer's disease. Predicting the onset of dementia is challenging even in the presence of amyloid, as time to progression varies considerably among patients and depends on the onset of neurodegeneration. Survival analysis can account for variability in time to event, but has not often been applied to MRI measurements beyond singular predefined brain regions such as the hippocampus...

AIM: To clarify clinical polymorphism of amyotrophic lateral sclerosis (ALS). MATERIAL AND METHODS: The study was based on records of a hospital personalized register. Ninety-four patients, aged from 25 to 81 years, diagnosed with ALS according to El Escorial criteria were included. Electromyography and, if necessary, transcranial magnetic stimulation and magnetic-resonance tomography were used to confirm the diagnosis. Disease progression was assessed with the ARSFRS...

An early and accurate in vivo diagnosis of rapidly progressive dementia remains challenging, despite its critical importance for the outcome of treatable forms, and the formulation of prognosis. Real-Time Quaking-Induced Conversion (RT-QuIC) is an in vitro assay that, for the first time, specifically discriminates patients with prion disease. Here, using cerebrospinal fluid (CSF) samples from 239 patients with definite or probable prion disease and 100 patients with a definite alternative diagnosis, we compared the performance of the first (PQ-CSF) and second generation (IQ-CSF) RT-QuIC assays, and investigated the diagnostic value of IQ-CSF across the broad spectrum of human prions...

The number of older people in the population is increasing faster than for any other age group. This population growth, while positive, is associated with increasing incidence of chronic and progressive diseases such as dementia. This requires older people to navigate services that may not be designed to meet their needs. This issue can be further amplified in culturally and linguistically diverse populations who often have limited English language proficiency and limited knowledge of diseases such as dementia...

The progressive aging of the world's population makes a higher prevalence of neurodegenerative diseases inevitable. The necessity for an accurate, but at the same time, inexpensive and minimally invasive, diagnostic test is urgently required, not only to confirm the presence of the disease but also to discriminate between different types of dementia to provide the appropriate management and treatment. In this study, attenuated total reflection FTIR (ATR-FTIR) spectroscopy combined with chemometric techniques were used to analyze blood plasma samples from our cohort...

OBJECTIVE: Late diagnosis of Alzheimer's disease (AD) may be due to diagnostic uncertainties. We aimed to determine the sequence and timing of the appearance of established early signs and symptoms in people who are subsequently diagnosed with AD. METHODS: We used systematic review methodology to investigate the existing literature. Articles were reviewed in May 2016, using the following databases: MEDLINE, PsycINFO, CINAHL, British Nursing Index, PubMed central and the Cochrane library, with no language restriction...

β-Methylamino-L-alanine (BMAA) is implicated in neurodegeneration and neurotoxicity, particularly in ALS-Parkinson Dementia Complex. Neurotoxic properties of BMAA have been partly elucidated, while its transcellular spreading capacity has not been examined. Using reconstructed neuronal networks in microfluidic chips, separating neuronal cells into two subcompartments-(1) the proximal, containing first-order neuronal soma and dendrites, and (2) a distal compartment, containing either only axons originating from first-order neurons or second-order striatal neurons-creates a cortico-striatal network...

BACKGROUND: Clinical practice guidelines recommend referral to nephrology when estimated glomerular filtration rate (eGFR) decreases to <30mL/min/1.73m(2); however, evidence for benefits of nephrology care are mixed. STUDY DESIGN: Observational cohort using landmark analysis. SETTINGS & PARTICIPANTS: A national cohort of veterans with advanced chronic kidney disease, defined as an outpatient eGFR≤30mL/min/1.73m(2) for January 1, 2010, through December 31, 2010, and a prior eGFR<60mL/min/1...

The differential diagnosis of atypical parkinsonian syndromes is challenging. These severe and often rapidly progressive neurodegenerative disorders are clinically heterogeneous and show significant phenotypic overlap. Here we review clinical, imaging, neuropathologic and genetic features of multiple system atrophy (MSA), progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and frontotemporal lobar degeneration (FTLD). The terms CBD and FTLD refer to pathologically confirmed cases of corticobasal syndrome (CBS) and frontotemporal dementia (FTD)...

Although illusions, hallucinations and delusions did not play a prominent role in James Parkinson's original clinical descriptions, the longitudinal view of disease progression he advocated has important lessons for the study of such symptoms today. A focus on longitudinal progression rather than individual symptoms led to the concept of PD psychosis-a spectrum of positive symptoms in Parkinson's disease. The publication of criteria for PD psychosis in 2007 helped unify the disparate set of symptoms, raising their profile and resulting in a rapid expansion of literature focussing on clinical aspects, mechanisms, and treatment...

We report on a 63-year old man suffering from rapid progressive dementia due to bilateral hippocampal primary CNS lymphoma. Early diagnosis especially in secondary dementia is essential because of potentially treatable aetiologies with regression of cognitive and behaviour abnormalities. Characteristic imaging findings especially in inflammatory and neoplastic lesions affecting the hippocampal structures are discussed.

This paper illustrates a proof of concept scenario for the application of comprehensive data visualisation methods in the rapidly changing aged care sector. The scenario we explored is population ageing and the dementias with an emphasis on the spatial effects of change over time at the Statistical Area 2 (SA2) level for the state of New South Wales. We did this using a combination of methods, culminating in the use of the Tableau software environment to explore the intersections of demography, epidemiology and their formal cost of care implications...

The heterogeneity of Alzheimer's disease contributes to the high failure rate of prior clinical trials. We analyzed 5-year longitudinal outcomes and biomarker data from 562 subjects with mild cognitive impairment (MCI) from two national studies (ADNI) using a novel multilayer clustering algorithm. The algorithm identified homogenous clusters of MCI subjects with markedly different prognostic cognitive trajectories. A cluster of 240 rapid decliners had 2-fold greater atrophy and progressed to dementia at almost 5 times the rate of a cluster of 184 slow decliners...

In the study of Alzheimer's disease, researchers often collect repeated measurements of clinical variables, event history, and functional data. If the health measurements deteriorate rapidly, patients may reach a level of cognitive impairment and are diagnosed as having dementia. An accurate prediction of the time to dementia based on the information collected is helpful for physicians to monitor patients' disease progression and to make early informed medical decisions. In this article, we first propose a functional joint model to account for functional predictors in both longitudinal and survival submodels in the joint modeling framework...

BACKGROUND: Due to demographic change, more proximal femoral fractures can be expected in the future. However, accurate growth rates as well as follow-up research extending more than 1 year postsurgery are still lacking. MATERIALS AND METHODS: First, we defined inclusion and exclusion criteria for the retrospective cohort study. Based on these, we collected all surgical interventions conducted between 1 January 2006 and 31 December 2015. For a total of 2000 consecutive procedures, we retrieved and analysed a total of 12 variables influencing mortality...
