Older people often present to healthcare services with acute and chronic problems that act together to adversely affect function. A common pathway comprises functional decline, followed by loss of independence and need for institutional care. However, this process is not necessarily inevitable or irreversible. Timely recognition of functional diffi...
Objective:
Despite recent high-profile advances in our understanding of rehabilitation post-stroke, the evidence base remains weaker than in other areas of stroke management. Under the aegis of the European Stroke Organisation a select committee was assembled to collate and appraise the evidence base for rehabilitation interventions.
Methods:
Fo...
Background:
frailty is common in older adults and associated with poor outcomes following illness. Although stroke is predominantly a disease of older people, our knowledge of frailty in stroke is limited. We aimed to collate the literature on acute stroke and frailty to estimate the prevalence of pre-stroke frailty and its associations with outco...

Background:
Many millions of people living with dementia around the world are not diagnosed, which has a negative impact both on their access to care and treatment and on rational service planning. Telehealth - the use of information and communication technology (ICT) to provide health services at a distance - may be a way to increase access to sp...
Background:
People who experience an ischaemic stroke are at risk of recurrent vascular events, progression of cerebrovascular disease, and cognitive decline. We assessed whether allopurinol, a xanthine oxidase inhibitor, reduced white matter hyperintensity (WMH) progression and blood pressure (BP) following ischaemic stroke or transient ischaemic...
Background
There is increasing interest in the concept of frailty in stroke, including both physical frailty and imaging-evidence of brain frailty. We aimed to 1)establish concurrent validity of a brain frailty measurement against traditional measures of physical and global frailty 2)establish prevalence of brain frailty in stroke survivors with an...
Introduction: Stroke and traumatic brain injury (TBI) accounts for 70% of secondary epilepsy in the adult population. The genetic architecture of epilepsy secondary to TBI or stroke is poorly understood.
Objective: We undertook a systematic review to test the association of single nucleotide polymorphisms (SNPs) with the risk of posttraumatic epile...
Background
People living with dementia are more likely to move into care homes. The true prevalence of dementia among care home residents in Scotland is not known. People living with dementia often interact with multiple social and healthcare services, thus routine data may offer a way to enhance understanding.
Aim
To compare national health and s...
Introduction
Moving into a care home is a significant, life-changing experience which occurs to address care needs which cannot be supported elsewhere. UK health policy recommends against moving into a care home from the acute hospital. However, this occurs in practice. Better understanding pathways into care homes could improve support for individ...
Background
Frailty and dementia have a bidirectional relationship. However, frailty is rarely reported in clinical trials for dementia and mild cognitive impairment (MCI) which limits assessment of trial applicability. This study aims to use a frailty index (FI) to measure frailty using individual participant data (IPD) from clinical trials for MCI...
Background:
Our understanding of the relationship between frailty and stroke, beyond the acute phase of stroke, is limited. We aimed to estimate the prevalence of frailty in stroke survivors using differing methods of assessment and describe relationships with stroke outcomes.
Methods:
We used data from three international population surveys (Am...
Background:
loss of skeletal muscle function, strength and mass is common in older adults, with important socioeconomic impacts. Subclinical hypothyroidism is common with increasing age and has been associated with reduced muscle strength. Yet, no randomized placebo-controlled trial (RCT) has investigated whether treatment of subclinical hypothyro...
Background
Pathways into care are poorly understood but important life events for individuals and their families. UK policy is to avoid moving-in to care homes from acute hospital settings. This assumes that moves from secondary care represent a system failure. However, those moving to care homes from community and hospital settings may be fundamen...
Background : The ‘impact’ of a scientific paper is a measure of influence in its field. In recent years, traditional, citation-based measures of impact have been complemented by Altmetrics, which quantify outputs including social media footprint. As authors and research institutions seek to increase their visibility both within and beyond the acade...

Standard methods for the meta-analysis of medical tests without a gold standard are limited to dichotomous data. Multivariate probit models are used to analyze correlated binary data, and can be extended to multivariate ordered probit models to model ordinal data. Within the context of an imperfect gold standard, they have previously been used for...
Frailty is a distinctive health state in which the ability of older people to cope with acute stressors is compromised by an increased vulnerability brought by age-associated declines in physiological reserve and function across multiple organ systems. Although closely associated with age, multimorbidity, and disability, frailty is a discrete syndr...
Background:
The IQCODE (Informant Questionnaire for Cognitive Decline in the Elderly) is a commonly used questionnaire based tool that uses collateral information to assess for cognitive decline and dementia. Brief tools that can be used for dementia "screening" or "triage" may have particular utility in primary care / general practice healthcare...
Background:
Delirium is an acute neuropsychological disorder that is common in hospitalised patients. It can be distressing to patients and carers and it is associated with serious adverse outcomes. Treatment options for established delirium are limited and so prevention of delirium is desirable. Non-pharmacological interventions are thought to be...
Background:
Various tools exist for initial assessment of possible dementia with no consensus on the optimal assessment method. Instruments that use collateral sources to assess change in cognitive function over time may have particular utility. The most commonly used informant dementia assessment is the Informant Questionnaire on Cognitive Declin...
Background:
The diagnosis of dementia relies on the presence of new-onset cognitive impairment affecting an individual's functioning and activities of daily living.
