[What significance does the topic 'prevention' have in social-psychiatric research? A systematic literature analysis].

AIM OF THE STUDY: Scientists and politicians currently pin great hopes on preventive activities in order to increase the health of particular target populations and to reduce illness related costs. This also holds true for mental disorders, which often show a chronic course of disease. The aim of the present study is to analyse the importance of prevention in social-psychiatric research. METHODS: Including 60 journals, listed in the Science Citation Index or the Social Science Citation Index for the psychosocial field, a systematic literature analysis was done for the year 2004. RESULTS: Only 14 percent of social-psychiatric original research paid attention to prevention. 39 percent of the prevention related publications refer to primary prevention, further 39 percent to secondary prevention, 22 percent focused on tertiary prevention. Research activities concentrated on prevention of substance related disorders as well as early detection or rehabilitation of schizophrenia. CONCLUSIONS: Social psychiatry has only partly responded to the growing importance of prevention in health care. Because many social-psychiatric questions are important for prevention research, social psychiatry should use their competences to facilitate prevention-studies. This holds particularly true for depressive disorders and dementia, which are conditions with high prevalence and substantial illness related costs.

[Age- and education-specific reference values for the cognitive test of the SIDAM (Structured interview for the diagnosis of dementia of the Alzheimer type, multi-infarct dementia and dementias of other etiology according to ICD-10 and DSM-IV)].

The SIDAM (Structured Interview for the diagnosis of Dementia of the Alzheimer type, Multi-infarct dementia and dementias of other etiology according to ICD-10 and DSM-IV) is a standardized interview for the diagnosis of dementia. It can also be used as a screening instrument for the diagnosis of different syndromes of dementia and mild cognitive impairment. At present there is no age- or education-specific standardization. This report presents age- and education-specific norms for the cognitive assessment of the SIDAM, obtained in a population-based sample of elderly people aged 75 and over (n=1001).

[Adaptation of a dementia test for use in visually handicapped persons exemplified by SIDAM (Structured Interview for the Diagnosis of Alzheimer disease, Multi-Infarct Dementia and Dementias of other Etiology)].

In epidemiological field studies on the prevalence and incidence of dementia, the problem of cognitive testing of visually impaired individuals is rarely discussed. In the Leipzig Longitudinal Study of the Aged (LEILA 75+) a version of the SIDAM (SIDAM-Structured Interview for the Diagnosis of dementia of the Alzheimer type, Multi-infarct dementia and dementias of other etiology) for the visually impaired was employed from which all items requiring image processing had been omitted (SIDAM-blind). In order to be able to interpret the test results, the final scores for the full SIDAM were estimated by linear transformation of the scores in the blind-version. The method of linear transformation is based on certain theoretical assumptions which are examined in this paper. Linear transformation of scores has proved to be a valid procedure only for individuals with high cognitive performances. Thus, an evaluation of estimated scores based on the norms for the original SIDAM has limitations. Consequently, age-specific norms for the SIDAM-blind are presented. Sensitivities and specificities for different cut-off points used to discriminate between demented and non-demented vision-impaired individuals are given.

Correlation between cortical theta activity and hippocampal volumes in health, mild cognitive impairment, and mild dementia.

Cognitive decline is known to be associated with both increased theta power over frontal regions and hippocampal atrophy. The aim of this study was to reveal the relation between these parameters in groups with mild dementia, mild cognitive impairment, and healthy control subjects. The authors examined a preliminary randomly selected sample of 39 right-handed subjects joining the Leipzig Longitudinal Study of the Aged, consisting of 17 normal elderly subjects, 12 patients with mild cognitive impairment, and 10 patients with mild dementia assessed by Clinical Dementia Rating. All subjects were between 75 and 85 years old (mean age, 78 years; standard deviation, 2.78 years) and underwent EEG and brain MRI. Mean spectral power densities were calculated, and hippocampal body volume was measured. Significant negative linear correlations between theta power over frontal regions and hippocampal volumes were found. The results support the assumption about a relationship between hippocampal atrophy and theta power, and may be helpful for a better understanding of the course of Alzheimer's disease.
