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

Abstract

Objective: A priority for research on manic-depressive or bipolar I disorder (BPI) for children and adolescents has been to search for early predictors of the illness.

Method: Medical record data were reviewed and systematically coded for a sample of 58 adult patients (32 males/26 females) with confirmed diagnoses of BPI to identify prodromal features and possible patterns of symptoms from the Amish Study.

Results: The most frequently reported symptoms included episodic changes in mood (depressed and irritable) and energy plus anger dyscontrol, with no significant gender differences. A progression 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 symptoms and onset of a documented BPI syndrome.

Conclusions: The data suggest testable hypotheses about specific symptoms and behaviors that may be useful for the early detection of children at highest risk for developing manic-depressive disorder.
