Background: Although mild cognitive impairment (MCI) represents a high-risk factor for developing dementia, little is known about the prevalence of MCI among patients of general practitioners (GPs). Aims: Estimation of age-specific prevalence for original and modified concepts of MCI and their association with sociodemographic, medical and genetic (apoE Ε4 genotype) factors among patients of GPs. Methods: A GP practice sample of 3,327 individuals aged 75+ was assessed by structured clinical interviews. Results: Prevalence was 15.4% (95% CI = 14.1–16.6) for original and 25.2% (95% CI = 23.7–26.7) for modified MCI. Rates increased significantly with older age. Positive associations were found for apoE Ε4 allele, vascular diseases and depressive symptoms. Conclusion: MCI is frequent in elderly patients of GPs. GPs have a key position in secondary prevention and care of incipient cognitive deterioration up to the diagnosis of dementia.

The results show that GPs recognise MCI in a very limited number of cases when based on clinical impression only. A further development of the MCI concept and its operationalisation is necessary. Emphasis should be placed on validated, reliable and standardised tests for routine use in primary care encompassing other than only cognitive domains and on case finding approaches rather than on screening. Then a better attention and qualification of GPs with regard to the recognition of MCI might be achievable.

A B S T R A C TIntroduction. This study evaluates the prevalence of chronic pain, intensity of pain, activity limitation, and pain-related diagnoses in German general practices.Methods. In 40 general practices, up to 50 consecutive patients presenting to general practitioners (GP) for routine medical consultation were questioned, and those reporting pain that lasted for more than 3 months received a questionnaire referring to intensity of pain and activity limitations. GPs received a questionnaire asking about the duration of treatment and diagnoses.Results. Three hundred forty-six out of 1,860 questioned patients suffered from pain that lasted for more than 3 months (a point prevalence of 18.4% [95% confidence interval 16.7-20.3]). The average degree of pain equaled 5 out of 10 points on a numerical grading scale (NRS); the average degree of activity limitation was 4.8 out of 10. In most cases, the pain was related to musculoskeletal degenerative diseases. Conclusion.Chronic pain patients constitute a considerable share of workload in general practice.
