Complications after ischaemic stroke, including both neurological and medical complications, are a major cause of morbidity and mortality. Neurological complications, such as brain oedema or haemorrhagic transformation, occur earlier than do medical complications and can affect outcomes with potential serious short-term and long-term consequences. Some of(More)
BACKGROUND Previous studies indicated overall relatively low prevalence of dementia in older people in China, which may be biased by studied samples or methods. We determined the prevalence of dementia cases and subcases in China and examined their socio-economic correlates. METHODS Using the Geriatric Mental State interview, we examined random samples of(More)
Despite advances in the diagnosis and treatment of acute ischaemic stroke in the past two decades, stroke has remained the third cause of mortality and the single leading cause of disability worldwide. The immediate goal of acute ischaemic stroke therapy is to salvage the ischaemic penumbra through recanalisation of the occluded cerebral blood vessel. This(More)
Previous attempts to identify neuroprotective targets by studying the ischemic cascade and devising ways to suppress it have failed to translate to efficacious therapies for acute ischemic stroke. We hypothesized that studying the molecular determinants of endogenous neuroprotection in two well-established paradigms, the resistance of CA3 hippocampal(More)
No pharmacological intervention has been shown convincingly to improve neurological outcome in stroke patients after the brain tissue is infarcted. While conventional therapeutic strategies focus on preventing brain damage, stem cell treatment has the potential to repair the injured brain tissue. Stem cells not only produce a source of trophic molecules to(More)
Stroke mostly occurs in elderly people and patient outcomes after stroke are highly influenced by age. A better understanding of the causes of stroke in the elderly might have important practical implications not only for clinical management, but also for preventive strategies and future health-care policies. In this Review, we explore the evidence from(More)
BACKGROUND Determinants for undetected dementia and late-life depression have been not well studied. AIMS To investigate risk factors for undetected dementia and depression in older communities. METHOD Using the method of the 10/66 algorithm, we interviewed a random sample of 7072 participants aged ≥60 years in six provinces of China during 2007-2011.(More)
Albumin is the most abundant protein in both CSF and plasma, and albumin quotient is often used to assess the functions of brain barriers especially that of the blood-CSF barrier [i.e. the choroid plexus (CP) which also secretes CSF]. In this study, we took albumin as a model molecule to investigate ageing-related alterations in the CSF-CP system in sheep.(More)
Association of passive smoking with cognitive impairment in older adults is unclear. We carried out a systematic literature review and a new study to determine the association. There were 3 cross-sectional studies published, showing a significant association of passive smoking with cognitive impairment (a relative risk (RR) of about 1.30-1.90). In the new(More)
