Prodromal symptoms before onset of manic-depressive disorder suggested by first hospital admission histories

Objective: A priority for research on manic-depressive or bipolar I disorde r (BPI) for children and adolescents has been to search for early predictor s of the illness. Method: Medical record data were reviewed and systematica lly coded for a sample of 58 adult patients (32 males/26 females) with conf irmed diagnoses of BPI to identify prodromal features and possible patterns of symptoms from this Amish Study. Results: The most frequently reported s ymptoms included episodic changes in mood (depressed and irritable) and ene rgy plus anger dyscontrol, with no significant gender differences. A progre ssion of ages is seen for the most commonly reported symptoms prior to age 16. The time interval was 9 to 12 years between appearance of the first sym ptoms and onset of a documented BPI syndrome. Conclusions: The data suggest testable hypotheses about specific symptoms and behaviors that may be usef ul for the early detection of children at highest risk for developing manic -depressive disorder.
