Memory self-assessment should not be used as a substitute measure of cognitive performance. Initiation of further diagnostic and therapeutic steps should be based on cognitive performance testing. Relaying solely on memory complaints would miss individuals in need and allocate resources to worried but cognitively healthy persons.

Background: Demographic changes indicating a general aging of the population suggest that the key role of general practitioners (GPs) in the diagnosis and management of dementia becomes more salient. The encouragement of GPs to collaborate with specialists is one chance to support GPs in performing a variety of functions associated with the diagnosis and management of dementia. Method: We used a questionnaire to investigate the role of referrals in diagnosing dementia at the primary care level and variables potentially influencing the referral behavior of German GPs (n = 563). Results: Only 31% of the GPs stated that the diagnosis of dementia was made predominantly in the context of referral to a specialist. The chance that referrals were made was increased for those GPs who entertained extensive cooperative relationships with self-help groups, psychologists, or the “Alzheimer Society”/“Brain League” (odds ratio [OR] 1.74) and for those GPs who perceived a great preparedness on the part of the relatives of the patient to comply with a referral (OR 2.29) as well as who noticed a great readiness among specialists to accept patients for the diagnosis of dementia (OR 2.55). GPs whose therapeutic orientation was shaped by further training and scientific literature were more likely to refer (OR 3.54). Discussion: Enhancing the liaison between GPs and specialist physicians by improving the psychogeriatric competence of GPs as well as the connection to nonmedical services is discussed.

Given its widespread occurrence and consequences, old-age depression has to be regarded as a major public health problem. Drug treatment has been proven effective in the majority of elderly individuals suffering from depression. This study presents pharmacoepidemiological data regarding the use of prescribed antidepressants and those purchased over the counter in the elderly. Furthermore, it links the data to simultaneously assessed depressive symptomatology. A representative survey on the utilization of prescription and over-the-counter antidepressant drugs and depressive symptomatology in community-dwelling (n = 1193) and institutionalized elderly individuals (n = 470) aged 75 and over was conducted in an urban region of Germany. Antidepressant use was found to be remarkably low (synthetic antidepressants: 2.2% of community dwelling individuals, 3.6% of institutionalized individuals; phytopharmaca containing hypericum perforatum: 4.2% of community dwelling individuals, 2.8% of institutionalized individuals). Two-thirds of the individuals treated with synthetic antidepressants received tri- and tetracyclic drugs, which were given at lower dosages than recommended for depression treatment. Selective serotonin reuptake inhibitors (SSRIs) were introduced in community-dwelling individuals only; none of the individuals cared for in residential and nursing homes received SSRIs. Only a minority of individuals with depressive symptoms were treated with antidepressants. The data suggests underutilization of antidepressants in the elderly, in which institutionalized elderly seem especially disadvantaged. The results call for increased efforts to discuss mental health issues in the public and to share scientific knowledge about symptoms, course and treatment options for depression. Furthermore, geronto-psychiatric competence of medical professionals, especially GPs, has to be systematically developed.

Recruitment procedures may exert a considerable influence on the outcome of health surveys in the elderly. Their impact on the prevalence of dementia will be measured in an epidemiological field study in a sample of 1,692 randomly selected individuals (75+). Face-to-face interviews were conducted using SIDAM (structured interview for the diagnosis of dementia of Alzheimer type, multi-infarct dementia and dementias of other etiology according to ICD-10 and DSM-III-R). Furthermore, proxy interviews were performed with relatives of fragile and functionally dependent individuals. Considering face- to-face interviews of community-dwelling individuals, a prevalence of moderate and severe dementia of 5.3% was found. When including information on respondents by proxy and institutionalized individuals, the prevalence rate increased to 6.3 and 10.5%, respectively. It will be argued that covering the whole population in question and ensuring high response rates are central issues to minimize selection bias.

According to the growing clinical interest in early indicators of dementia, numerous studies have examined the association between subjective memory complaints and cognitive performance in old age. Their results are contradictory. In this paper, studies carried out over the last 10 years are compared with regard to the study design and the assessment instruments used. The results are discussed with particular reference to the diagnostic validity of subjective memory complaints. The majority of case-control studies and cross-sectional studies of non-representative samples could not demonstrate an association between subjective memory complaints and cognitive performance. Most field studies of larger representative population samples, however, have come to the opposite conclusion. A consistent assessment of these statistically significant associations against the background of diagnostic validity showed that memory complaints cannot be taken as a clear clinical indicator for cognitive impairment. Subjective memory complaints may reflect depressive disorders and a multitude of other processes, of which an objective impairment of cognitive performance is just one aspect. As a consequence, an inclusion of subjective memory complaints as a diagnostic criterion for the diagnosis of "mild cognitive disorder" according to ICD-10 is not justified.
