What are antecedents?

Antecedents, including language problems, are usually subtle deviations in development that may become evident during childhood or adolescence. The presence of these deviations may foreshadow the later development of bipolar disorder, however most children who exhibit antecedents do not develop the disorder. Studies exploring antecedents are ideally based on representative, population-based samples that follow the group from birth through childhood and adolescence to adulthood.

What is the evidence from long-term studies on language problems as antecedents of bipolar disorder?

Moderate to low quality evidence suggests a medium-sized effect of poor expressive language, but not receptive language, in childhood of people who developed mania in adulthood. There was no association with childhood speech problems in general and later bipolar disorder.
