In a cyclical and recurring illness such as bipolar disorder, prodrome detection is of vital importance. This paper describes manic and depressive prodromal symptoms to relapse, methods used in their detection, problems inherent in their assessment, and patients' coping strategies. A review of the literature on the issue was performed using MEDLINE and EMBASE databases (1965-May 2006). 'Bipolar disorder', 'prodromes', 'early symptoms', 'coping', 'manic' and 'depression' were entered as key words. A hand search was conducted simultaneously and the references of the articles found were used to locate additional articles. The most common depressive prodromes are mood changes, psychomotor symptoms and increased anxiety; the most frequent manic prodromes are sleep disturbances, psychotic symptoms and mood changes. The manic prodromes also last longer. Certain psychological interventions, both at the individual and psychoeducational group level, have proven effective, especially in preventing manic episodes. Bipolar patients are highly capable of detecting prodromal symptoms to relapse, although they do find the depressive ones harder to identify. Learning detection, coping strategies and idiosyncratic prodromes are elements that should be incorporated into daily clinical practice with bipolar patients.
