Bipolar Spectrum Disorder And The Bipolar Spectrum Diagnostic Scale

By Sheila Wilson

The diagnostic tool Bipolar Spectrum Diagnostic Scale (BSDS) contains nineteen sentences and a rating scale. If a person is having symptoms of mood disorders, a mental health professional may use the Bipolar Spectrum Diagnostic Scale to determine if the person has bipolar disorder.

S. Nassir Ghaemi, M.D., M.P.H. refined the Bipolar Spectrum Diagnostic Scale originally developed by Ronald Pies, M.D. This diagnostic tool is considered sensitive and can detect all variations and levels of severity of bipolar disorder.

After working with a number of people whose "treatment-resistant depression" was later determined to be undiagnosed bipolar spectrum disorder, Pies was motivated to design the diagnostic tool to accurately diagnose bipolar spectrum disorder that may otherwise be missed. Bipolar spectrum disorder is not an official diagnosis in the Diagnostic and Statistical Manual (DSM).

Some mental health professionals use the term bipolar spectrum disorder to include people who have bipolar symptoms, but whose symptoms are not severe enough to be diagnosed with bipolar disorder. Bipolar disorder symptoms that are milder than the guidelines of the DSM is sometimes called soft bipolar disorder or soft bipolar spectrum disorder.

The Bipolar Spectrum Diagnostic Scale has two sections. The first section has nineteen sentences that describe the main symptoms of bipolar disorder. The patient is to check the sentences that describe their feelings or behaviors.

The second section contains a rating scale. The patients must rate how well the nineteen sentence narrative of section one as a whole fits their personal experiences. The number of the sentences checked in first section is the score for that section.

The score of the second section depends on how the nineteen sentence narrative is rated by the patient. Six points are added to the patient's score if the patient indicated that the story fits them very well or almost perfectly. If the patient says the narrative fits fairly well, four points are added to the patient's score.

Two points are added if the patient's rating is that the story fits to some degree but not in most respects. No points are added to the patient's score if the person says the story does not describe them at all.

Bipolar disorder is considered highly likely if the patient's score is nineteen or higher. If the score is eleven to eighteen, there is a moderate probability of bipolar disorder. There is a low probability if the score is six to ten. Bipolar disorder is considered very unlikely if the score is under five or less. - 29881
