Cognitive impairment creates significant challenges for patients, their families and friends, and clinicians who provide their health care. Early recognition allows for diagnosis and appropriate treatment, education, psychosocial support, and engagement in shared decision-making regarding life planning, health care, involvement in research, and financial matters. An IAGG-GARN consensus panel examined the importance of early recognition of impaired cognitive health. Their major conclusion was that case-finding by physicians and health professionals is an important step toward enhancing brain health for aging populations throughout the world. This conclusion is in keeping with the position of the United States’ Centers for Medicare and Medicaid Services that reimburses for detection of cognitive impairment as part the of Medicare Annual Wellness Visit and with the international call for early detection of cognitive impairment as a patient’s right. The panel agreed on the following specific findings: (1) validated screening tests are available that take 3 to 7 minutes to administer; (2) a combination of patient- and informant-based screens is the most appropriate approach for identifying early cognitive impairment; (3) early cognitive impairment may have treatable components; and (4) emerging data support a combination of medical and lifestyle interventions as a potential way to delay or reduce cognitive decline.
This article examines the changing demographics of China, with particular attention paid to the effect of the one-child policy in relation to long-term care of older people. It also examines the current state of health care for older people. Long-term stays characterize hospital care. Most geriatric syndromes are less common in hospitalized older people (e.g., delirium, falls), but some (e.g., polypharmacy) are more common. A high volume of patients and brief targeted visits characterize outpatient care. Nursing homes exist in China, but relatively fewer than in the most developed countries.Geriatric departments in university-based hospitals primarily have developed out of a need to care for retired government officials and workers. There are no formal geriatric fellowships or national board certifications in geriatrics Health care is primarily based on fee for service. Not all elderly have healthcare insurance. Although costs of health care and medications are less expensive than in the United States, they are relatively high for lower-and middle-class Chinese and have increased more quickly than has the standard of living in the past 20 years.Family and community support for older people is strong in China. Some older people have one-to-one care from a baomu (literally ''protection'' (bao) ''mother'' (mu)), a type of live-in maid who also provides care for the older person. Some of the challenges facing China in the care of its aging population are how to increase geriatric research and training, how to care for the uninsured or underinsured, and how to handle the inevitable growth of disabled and frail older people.
BackgroundDelirium is a common and serious problem among acutely unwell persons. Alhough linked to higher rates of mortality, institutionalisation and dementia, it remains underdiagnosed. Careful consideration of its phenomenology is warranted to improve detection and therefore mitigate some of its clinical impact. The publication of the fifth edition of the Diagnostic and Statistical Manual of the American Psychiatric Association (DSM-5) provides an opportunity to examine the constructs underlying delirium as a clinical entity.DiscussionAltered consciousness has been regarded as a core feature of delirium; the fact that consciousness itself should be physiologically disrupted due to acute illness attests to its clinical urgency. DSM-5 now operationalises ‘consciousness’ as ‘changes in attention’. It should be recognised that attention relates to content of consciousness, but arousal corresponds to level of consciousness. Reduced arousal is also associated with adverse outcomes. Attention and arousal are hierarchically related; level of arousal must be sufficient before attention can be reasonably tested.SummaryOur conceptualisation of delirium must extend beyond what can be assessed through cognitive testing (attention) and accept that altered arousal is fundamental. Understanding the DSM-5 criteria explicitly in this way offers the most inclusive and clinically safe interpretation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
