About Bipolar Disorder in Adult Patients
Bipolar Depression Is Commonly Misdiagnosed in Adults1
Unipolar depression is the most common misdiagnosis, followed by anxiety disorders, schizophrenia, personality disorders, and substance- or alcohol-abuse disorders1
- Depressive symptoms of unipolar depression are the same as those of bipolar depression2
Many adult patients wait more than 10 years from the onset of symptoms to receive an accurate diagnosis of bipolar disorder1,3
Screening tools such as the Mood Disorder Questionnaire (MDQ) and Composite International Diagnostic Interview (CIDI) 3.0 have been developed to help clinicians uncover a history of mania to differentiate bipolar depression from unipolar depression4,5
Depression Is Often Seen at the Onset of Bipolar Disorder in Adult Patients6
On average adult patients with bipolar disorder experience 3 times more depression than mania7
In some cases adult patients may experience depressed moods without mood elevation for 5 or more years8
Symptoms of mania may be overlooked or underreported9,10
Antidepressants May Be Ineffective for Bipolar Disorder in Adult Patients10-12
Treatment for bipolar disorder in adult patients most often starts with antidepressants, despite limited evidence of effectiveness10-12
Use of antidepressants in bipolar disorder:
- May be ineffective, resulting in multiple-drug treatment failure10,11
- May induce an affective switch to mania or hypomania10,11
- Non-response to antidepressants may be an indicator of bipolar disorder; therefore, it may be useful for adult patients who are not responding to treatment with antidepressants to be screened for bipolar disorder11
Only a few FDA-approved agents are indicated for the treatment of bipolar depression10
