    Notes: Summary In a longitudinal cohort study of young adults from the Canton of Zurich in Switzerland (Zurich Study), seasonal patterns of several psychiatric and psychosomatic syndromes were investigated in two interviews over a period of three years. At an age of 27–28 years, 23% of the depressives, 15% of the neurasthenic subjects, and 14% of the subjects with backache reported an increased susceptibility in autumn and/or winter. With respect to the course we found that 10.4% of the subjects of the longitudinal sample (n=417) suffered from seasonal depression (including individuals with subsyndromal seasonal difficulties) overtwo consecutive years. Specific symptoms, such as hypersomnia, increase of appetite or weight gain, were not found to be consistently associated with seasonal depression. A comparison of actual and retrospective reports on seasonal depression resulted in a very low reliability. In view of these results the seasonal subtype of depression should be diagnosed with caution, except when the diagnosis is based on longitudinal observations and/or external sources of information (e.g. family members, partner).

    Notes: Summary Linkage analysis has been successful in identifying the genetic basis of numerous Mendelian diseases. These successes were due in part to the rapid developments in molecular biology, which have yielded a plethora of informative genetic markers. Although there is strong evidence that the manifestation of schizophrenia and bipolar affective disorders is controlled by genes, no evidence for linkage has been established. For psychiatric disorders, the most important limiting factor is likely to be the lack of single loci with very large effects that occur with any relevant frequency. The difficulties of linkage studies in psychiatric disorders are discussed with reference to non-psychiatric genetic diseases for which linkage to genetic markers has been successful. Recommendations for collecting information to clarify the patterns of transmission of the psychiatric disorders are described.

    Notes: Abstract This study examines the 1 year prevalence rates of headache syndromes in an epidemiologic cohort study of young adults ages 29–30 in Zurich, Switzerland. The 1 year prevalence rates of headache subtypes were 3.3% for migraine with aura and 21.3% of migraine without aura as defined by the International Headache Society (IHS) criteria. The demographic distribution, clinical features, sequelae, and treatment patterns of subjects with specifc headache subtypes are described. The rates of migraine are compared to those of other community samples that have employed the IHS criteria for headache subtypes. Subjects with migraine reported pervasive impairment in nearly every life role including occupation, leisure, and social relationships. Despite the substantial degree of impairment in occupational and social functioning that was associated with migraine, an extremely low proportion of subjects had received professional treatment for headache. These results suggest that a concerted effort should be directed towards education regarding the classification of headache and the availability of efficacious treatment for migraine.

    Notes: Summary This paper reports on the prevalence of emotional and somatic symptoms of the pre- and peri-menstrual phases of the female reproductive cycle among women who participated in a 10-year prospective epidemiologic cohort study of young adults in Zurich, Switzerland. The association between menstrual syndrome and sociodemographic features, personal habits, and psychopathologyis investigated. The findings confirm those of previous studies, which have shown that symptoms of menstrual syndrome are quite common in non-clinical samples in the community, and increase with age. Women with menstrual problems could be distinguished from other women in a number of domains, including demographic characteristics such as nulliparity, higher educational level, distressing life events, lack of oral contraceptive use, psychiatric disorders, and personality traits. The combined evidence for a strong association between menstrual syndrome and anxiety, both in the subjects and their relatives, suggests that menstrual problems may represent a manifestation of underlying anxiety disorders rather than strictly affective disorders as traditionally believed.
