Symposium 6
The intergenerational transmission ofaffective disorders
Symposium Leader: Peter CooperUniversity of Reading, UK6 (overview)
Both depression and anxiety disorders are stronglyfamilial, and both top down and bottom up studies revealsubstantial intergenerational transmission. The pro-cesses by which such transmission is effected, and theextent to which genetic and environmental factors areimplicated, are poorly understood. Longitudinal researchprovides a powerful means of elucidating causal proces-ses. A group of five researchers who have collaborated inresearch in this field for several years will present papersconcerned with the intergenerational transmission ofboth depression and anxiety. The focus will be on themechanisms by which disorder is transmitted fromparent to child. The research presented will focus onstudies of depression and social phobia and will be basedon samples studied longitudinally in Cambridge, Read-ing and Bristol. Biological, cognitive, socio-emotional,and environmental risk factors for disorder will beexamined, and questions such as whether there exist‘sensitive periods’ in development during which envir-onmental exposures may have a particular impact will beconsidered. There will be four papers: (i) The impact ofmaternal postpartum depression on adolescent HPA axisfunction and mood disturbance: the Cambridge long-itudinal study. (ii) Sex differentiated effects of a historyof maternal depression on risk of depression in offspring.(iii) Depressive symptoms in men in the post-natalperiod and their associations with later child psycho-
pathology. (iv) Intergenerational transmission of socialphobia: evidence from longitudinal and experimentalstudies.
