Epidemiological, longitudinal and treatment studies have emphasized th
e significance of the common somatic presentations of distress (e. g.
chronic fatigue, musculoskeletal pain, gastrointestinal symptoms). Aet
iological models for these syndromes now emphasize unique genetic, cog
nitive and neurobiological factors. Treatment paradigms emphasize the
central role of cognitive-behavioural approaches but their implementat
ion, particularly in primary care, remains problematic. (C) 1998 Rapid
