There is a rising prevalence of dementia in line with the continuing demographic transition. More timely diagnosis of dementia is recommended. Brief cognitive tests are useful as they provide a rapid assessment that can indicate the possibility of dementia and identify people for detailed cognitive assessment. Many brief cognitive tests have been developed and practitioners need information in order to select a test that performs well, is acceptable to patients, and is suitable for the relevant care setting. In a structured review, we identified twelve brief cognitive impairment tests, of which six have been sufficiently studied and can be recommended for use in routine care.

Dementia is a syndrome characterized by a progressive impairment in cognition, function and behaviour, with a considerable burden in terms of health and social care, and economic costs. As Alzheimer's disease and other dementias advance, the patient's capacity, competence and possibility of participation in decision-making decrease. Key points in managing people with dementia include screening of cognitive impairment, neuropsychological assessment, laboratory tests and neuroimaging, genetic tests, informed consent, inclusion in clinical trials and discussion of advance directives, driving, managing finances and testamentary capacity, pharmolocogical and non-pharmacological treatment and also palliative and end-of-life care. In this article we review these crucial points in decision-making for people with dementia and their families and caregivers.

Age-related changes affect all structures of the eye, and while age-related changes may influence the quality of vision, it is important to distinguish age-related physiological changes from pathological changes. This is important particularly when identifying pathological changes that may be treatable. The prevalence of visual loss increases substantially after 60 years of age and poor vision is the second most prevalent physical disability in older people. This review describes the normal ageing changes of the eye and outlines common ophthalmic diseases affecting older people. We refer to recent advances in diagnosis and treatment, and relevant current research.

Human sexuality is a complex interaction of biological, social and emotional factors. When any or all of these factors are disrupted by a progressive dementia it is unsurprising that sexual ‘problems’ are identified. Most sexual behaviour ‘problems’ relate to expressions of normal sexuality complicated by changes in relationships, care needs and cognitive function, and complex ethical and legal considerations emerge. Rarely, new and severe hypersexual or paraphilic behaviours arise de novo, usually due to damage to certain brain areas, and sometimes due to medication side-effects, psychiatric disorder or delirium. Evidence and approaches to assess and to manage sexual behaviour problems in dementia are discussed.

The quality of life (QoL) of older people is of increasing interest in China, due to its ageing population. A systematic review of published QoL studies was undertaken to examine different measurements and related factors of QoL of older people in China. Papers were identified by searching the following electronic databases: Web of Science, PsycINFO, MEDLINE, PubMed, CINAHL, China Academic Journal and VIP Database for Chinese Technical Periodicals. Fifteen studies were included in the review, using eight different QoL measurement tools. Health status, psychological well-being, social well-being, housing and socio-demographic factors were identified as important related factors of QoL. Further studies are needed using valid measurement tools to explore more factors, especially culturally specific contributors, to the QoL of older people.

This systematic review, with meta-analyses conducted where data were available, aimed to investigate the prevalence of symptoms of depression and anxiety in mild cognitive impairment (MCI), and to establish how symptoms of depression and anxiety relate to the progression from no cognitive impairment to MCI, and from MCI to dementia. Sixty studies were included in the review. Meta-analyses indicated that symptoms of depression and anxiety were more prevalent in people with MCI than in people with normal cognitive function, and increased the risk of progression from no cognitive impairment to MCI. There were mixed results regarding the effect of such symptoms on progression from MCI to dementia. The findings highlight the need for more research in this area, which can inform attempts to slow or halt the progression of cognitive impairment in later life, with resulting benefits for quality of life.
