Childhood-onset bipolar misread for decades
Hornbacher's symptoms began in early childhood — sleepless nights, racing thoughts, terror, and wild swings of mood — but were treated through adolescence and her twenties as eating disorders, alcoholism, and self-harm rather than as one underlying illness. She was not diagnosed with rapid-cycling bipolar disorder until she was twenty-four, after years of hospitalisations. The case shows how a primary mood disorder can hide behind the dramatic secondary behaviours that clinicians treat first.
