Numerous recent studies have challenged the widely held belief that atypical antipsychotics are safe and effective options for the treatment of behavioural problems such as agitation in patients with dementia. Accordingly, there is a need to reconsider the place of atypical antipsychotics in the treatment of patients with dementia. The present article is intended to assist clinicians with the assessment and pharmacological management of agitation in patients with dementia. ⋯ The best evidence currently exists for cholinesterase inhibitors and serotonin-specific reuptake inhibitor antidepressants. Emerging reports suggest that numerous other medications, for example, antiepileptics, lithium, anxiolytics, analgesics, beta-adrenoceptor antagonists, cannabinoid receptor agonists and hormonal agents, may prove to be viable alternatives to antipsychotics for the treatment of severe DRA and more research is urgently needed to help assess the effectiveness of these agents. A comprehensive biopsychosocial assessment and treatment plan is likely the most effective way to manage DRA.

What defines abnormal lung function in older adults with chronic obstructive pulmonary disease?
Chronic obstructive pulmonary disease (COPD) is a very common lung disease most often related to a history of smoking. It becomes more prevalent with increasing age but remains under-diagnosed and under-treated in the elderly population. The Global Initiative for Obstructive Lung Disease (GOLD) programme has been instrumental in providing standard diagnostic criteria as well as recommendations for prevention and management of COPD. ⋯ A conservative recommendation is to perform spirometry in symptomatic individuals. It is important to remember that while COPD is under-diagnosed in the elderly, this group is also at a higher risk of being falsely classified as having airflow obstruction using the 70% ratio recommended by GOLD. This can result in unnecessary use of medications and increased risk of adverse effects to which the elderly are more prone.

Zoledronic acid (Aclasta; Reclast), a third-generation nitrogen-containing bisphosphonate, is the first once-yearly treatment to have been approved for use in patients with postmenopausal osteoporosis or at high risk of fracture. Intravenous zoledronic acid 5 mg once yearly is effective in reducing the risk of several types of fracture in patients with postmenopausal osteoporosis or recent low-trauma hip fracture. ⋯ Additional comparative data are required to definitively position zoledronic acid with respect to other agents. In the meantime, intravenous zoledronic acid 5 mg once yearly is a convenient and effective treatment option that may have an advantage over some other agents, for which adherence to treatment regimens is a recognized problem.

Increased life expectancy is associated with an increased prevalence of chronic diseases and drug consumption. Changes often occur in the medication regimen after hospitalization. The extent and nature of these changes and the adherence of elderly patients have not yet been fully investigated. ⋯ The majority of elderly patients experienced modifications in their medication regimen during the first month following hospital discharge. Thirty percent of patients were non-adherent to at least one drug. To improve adherence to a hospital medication regimen, patients should be encouraged to visit their GP and the number of long-term drugs should be reduced.

In France, there is evidence to suggest that 50% of elderly individuals are prescribed psychotropic medications. However, it is known that use of these agents increases the risk of falls, fractures and delirium in older people. ⋯ PIM use is common among hospitalized older adults in France. The most important determinant of risk of receiving a psychotropic medication or a PIP was the number of drugs being taken. The elderly, who have multiple co-morbidities, complex chronic conditions and are usually receiving polypharmacy, are at increased risk for adverse drug events. These adverse events are often linked to problems that could be preventable such as delirium, depression and falls. Regular review of prescriptions would help optimize prescription of psychotropics in the elderly. The Beers list is a good tool for evaluating PIMs but is too restrictive with respect to psychotropics; in the latter respect, the list could usefully be widened.
