this study on place of death raises exploratory questions on end-of-life care for patients with dementia which has implications on health and social care policies related to dementia.

SummaryAnxiety has reported prevalence rates between 38 and 72% among people with dementia. It has a negative impact on cognitive impairment and is associated with agitation and poor quality of life. The presence of excessive anxiety can be difficult to establish in people with dementia, especially when expressive or receptive speech is impaired. Unfortunately, there is a lack of research on the treatment of anxiety in dementia, and also on the wider issue of the management of anxiety disorders in old age. We explore the prevalence, presentation and diagnosis of anxiety in dementia and discuss the therapeutic options available.

SummaryElectroencephalography (EEG) is a non-invasive investigation that can aid the diagnosis of psychiatric and neuropsychiatric disorders. A good predictor of an abnormal EEG recording is the presence of an organic factor identified during the clinical assessment. The non-invasiveness and low cost of the procedure and its ability to measure spontaneous brain activity appear to attract clinicians to utilise this investigative tool. However, studies have reported that EEGs arising from psychiatric referrals have the lowest abnormality detection rate. The focus of this article is to improve this by highlighting the current pitfalls and providing recommendations for appropriate utilisation of EEG. We describe specific EEG changes associated with major psychiatric disorders. We conclude by offering pragmatic considerations when referring a patient for EEG, emphasising the fact that the information provided to the neurophysiologist plays a crucial role in interpreting the EEG recording in a diagnostically meaningful way.

SummaryVery little attention has been paid to the invisible epidemic of substance misuse among older people in the UK. This article looks at the prevalence of substance misuse in the people over the age of 60. The reasons for difficulty in diagnosing substance misuse are explored and ways to improve diagnostic ability are discussed. Substance misuse leads to severe physical and psychiatric morbidity that is being managed by meagre resources. The article provides recommendations on specific issues related to interventions, biological and psychosocial, and training of psychiatrists.

Purpose -The aim of this study is to explore the characteristics of a group of patients over 50 years old who are entering a substitution treatment programme for opioid dependence and to compare the characteristics of this group with those aged under 50 who are enrolled in the same substitution treatment programme.Design/methodology/approach -This is a cross sectional survey involving 92 cases in the 50 and above age group and 194 cases in the under 50 age group from community drug and alcohol services. Data were collected on demographic details, substance misuse and treatment history and progress with treatment. All the data were analysed using the Statistical Package for the Social Sciences (SPSS), version 1.1. Statistical significance between fewer than 50 and 50 þ groups were assessed using Fisher's exact test.Findings -Amongst the 92 in the group 50 years and above, 67 (average dose ¼ 63.25 mg) were on methadone maintenance (average dose ¼ 63.25 mg) and 19 (average dose ¼ 10.37 mg) on buprenorphine. In total, 11 per cent started using opiates after the age of 50. Sixty per cent used other substances out of which 31 per cent used multiple substances. Benzodiazepines, cocaine and amphetamines were the common substances of misuse. Thirty seven were infected with HCV. Comorbid rates for physical and mental illnesses were 64 per cent and 62 per cent, respectively. Nearly 86 per cent achieved good compliance with the treatment programme. Statistically higher rates of being single, lacking stable accommodation, prescription of buprenorphine, high dose prescriptions and lower rates of blood-borne viruses, physical health and mental health, past forensic history were found in the under 50 age group compared with the 50 þ age group.Practical implications -There are a considerable number of patients above the age of 50 in maintenance treatment and they differ from the less than 50 age group. Old age and substance misuse psychiatrists should be aware of the prevalence of comorbid substance misuse, physical (including blood borne viruses) and psychiatric disorders in this population. Further research is required in this neglected area and a service provision should be based on such robust research.Originality/value -This is the first study to the authors' knowledge that compares the demographic and treatment profiles of under 50 and over 50 years by age of patients in a methadone maintenance treatment programme. It clearly points to significant differences in the profiles based on age which will have implications for service provision which will have to take into account these age-related differences in particular related to physical health and social needs.

The aim of this study is to pilot FORGET as screening tool for dementia in community OP clinic and acute medical hospital assessments. Sample size included 30 each of memory clinic and acute medical hospital patients. Assessments included FORGET and MMSE. Psychometric test parameters were calculated for FORGET (Cut-off >1 in OP clinic and >3 in acute medical hospital). Of 30 referrals to memory clinic, 25 had dementia. A score >1 on FORGET had sensitivity 80%, specificity 80%, PPV 95.24%, NPV 44.44%, OR 16.00 (p = 0.02) for diagnosis of dementia. Of 30 acute hospital referrals, 20 had dementia. A score >3 on FORGET had sensitivity 95%, specificity 90%, PPV 95% and NPV 90%, OR 171 (p = 0.0005). FORGET at a score of >1 in community and >3 in acute medical hospital is a useful screening tool for dementia.
