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 disorder (BPI) for children and adolescents has been to search for early predictors of the illness.


METHODS
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.
