Long-term depression misdiagnosis reveals hidden bipolar disorder in two patients
Two women spent years treated for depression before hospital assessments identified bipolar disorder, highlighting gaps in mental-health screening.
Kimberley Atkinson was diagnosed with depression as a teenager and spent 14 years on antidepressants before a manic episode led to compulsory hospitalization, where doctors finally identified bipolar I disorder. Similarly, Jacqui Armstrong endured three decades of depressive treatment, multiple admissions and a suicide attempt before a psychiatrist asked about hypomanic symptoms and diagnosed bipolar II. Both women report significant improvement after receiving appropriate mood-stabilising medication.
Researchers estimate up to one in five severe depression cases could be bipolar, and Professor Danny Smith of the University of Edinburgh calls for urgent revision of screening protocols, a view supported by the Royal College of Psychiatrists and Bipolar UK. Misdiagnosis can worsen health, as antidepressants may aggravate bipolar symptoms, making early, accurate detection a potential lifesaver.
Why it matters
Accurate diagnosis prevents harmful treatment and improves lives for many misdiagnosed depression patients.
