Acute juvenile onset mania has a high rate of recovery and low chronicity. The relapse rate was high and most of these occurred in the first 3 years despite aggressive prophylactic treatment. The effectiveness of currently used thymoleptics, in particular lithium, in the prophylaxis of juvenile bipolar disorder needs to be evaluated in controlled studies.

Objective: The aim of this paper is to determine potentially modifiable factors associated with the high proportion of patients who are readmitted to adolescent psychiatric units. Method: The case notes of 112 adolescents admitted over 1 year to an acute adolescent psychiatry unit were reviewed. Socio-demographic and clinical variables were compared between those who were readmitted over a 12-month period post discharge and those who were not. Results: The readmission rate over a 12-month period was 31%. Males were significantly more likely to be readmitted. No other statistically significant predictors of readmission were identified. There was a trend towards readmission for those with bipolar disorder and a trend away from readmission for those with adjustment disorders. A history of sexual abuse and cluster B personality traits were significantly related to a history of previous admission, but not with subsequent readmission. Conclusions: Readmission is influenced by a number of factors, which may not be easily identified by a chart review. Prospective studies which follow-up adolescents for several years after discharge are needed.

The purpose of the present paper was to compare currently available diagnostic guidelines for juvenile bipolar disorder with respect to utility in research and clinical practice. A systematic search of psychiatric, medical and psychological databases was conducted using the terms 'juvenile bipolar disorder', 'paediatric bipolar disorder' and 'guidelines'. Three main sets of guidelines issued by the National Institute of Health and Clinical Excellence (UK), The National Institute of Mental Health (USA) and Child Psychiatric Workshop (USA) were found. There were key differences in the recommendations made by each regarding the diagnosis and symptomatic presentation of juvenile bipolar disorder. Although the diagnosis of juvenile bipolar disorder is gaining increased recognition, its definition remains controversial. It is recommended that clinicians and researchers need to develop diagnostic guidelines that have clinical salience and can be used for future research by incorporating key features of those that are currently available.
