Bipolar Test Free | Bipolar Disorder Test (MDQ Test)
Mood Disorder Questionnaire (MDQ) — Test for Bipolar 1, Bipolar 2 & Manic Depression
Bipolar Disorder Screening Test (MDQ)
This free bipolar test uses the MDQ (Mood Disorder Questionnaire) — a validated screening tool for bipolar disorder used by psychiatrists and mental health professionals worldwide. The MDQ was specifically designed to address one of the most common diagnostic failures in psychiatry: missing the manic and hypomanic episodes that define bipolar disorder in people who present primarily complaining of depression. If you have ever had periods of unusually high energy, reduced need for sleep, racing thoughts, or felt driven to do more than usual — alongside periods of depression — this screening is designed to capture that picture.
Manic Episodes
Elevated mood, racing thoughts, reduced sleep, impulsivity
Bipolar 1 vs 2
Full mania (Bipolar 1) vs hypomania (Bipolar 2)
Bipolar Depression
Depressive episodes alternating with elevated mood
Instant Results
Clear screening result with personalised guidance
✓ MDQ validated screening tool used in psychiatric practice
✓ Screens for both Bipolar 1 (mania) and Bipolar 2 (hypomania)
✓ Helps differentiate bipolar disorder from depression and BPD

Frequently Asked Questions About Bipolar Disorder Testing
What is the MDQ and how does it work?
The Mood Disorder Questionnaire (MDQ) is a 13-item yes/no screening tool developed to detect bipolar disorder, particularly in people who present for treatment of depression. It asks about a specific set of manic and hypomanic symptoms, then asks whether several of those symptoms occurred simultaneously, and finally asks about the level of impairment they caused. A positive screen requires 7 or more "yes" answers, a "yes" to the clustering question, and moderate or serious impairment. This three-part threshold reduces false positives while capturing clinically significant patterns.
Can someone have bipolar disorder without ever feeling "manic"?
Yes, particularly with Bipolar 2. Hypomania — the elevated mood state in Bipolar 2 — is often not recognised as abnormal because it feels positive rather than distressing. People describe periods of unusual productivity, creativity, confidence, and energy that feel like their "best self" rather than a symptom of illness. It is only when these periods are placed in the context of the full mood history — and alongside the depressive episodes — that the bipolar pattern becomes visible. Many people with Bipolar 2 are diagnosed with treatment-resistant depression for years before the hypomanic history is identified.
Is there a blood test or brain scan that can diagnose bipolar disorder?
No definitive biological test for bipolar disorder currently exists. Diagnosis is clinical — based on a thorough history of mood episodes, their timing, duration, and severity. Blood tests are used in bipolar evaluation, but to rule out medical conditions that can mimic bipolar symptoms (thyroid disorders, vitamin deficiencies, hormonal conditions) and to monitor medication levels (particularly lithium, which requires regular blood level monitoring). Brain imaging research has identified group-level differences in brain structure and function between people with and without bipolar disorder, but these differences are not specific enough to be diagnostically useful for individual patients.
How is bipolar disorder different from depression?
Both conditions involve depressive episodes that can look identical at the symptom level. The fundamental difference is that bipolar disorder also involves episodes of elevated mood (mania or hypomania) that unipolar depression does not. Because people with bipolar disorder are usually not in an elevated phase when they seek treatment, distinguishing between the two requires a careful mood history going back years — not just an assessment of current symptoms. Key questions include: Have you ever had periods of unusually high energy, reduced need for sleep, or dramatic increases in goal-directed activity? Have you ever done things during elevated mood periods that felt excessive, foolish, or risky in retrospect? Has anyone in your family been diagnosed with bipolar disorder?
What should I bring to a bipolar disorder evaluation?
The most valuable thing you can bring is a detailed mood history: a timeline of your significant depressive episodes (when they occurred, how long they lasted, what they felt like), and any periods of elevated mood, unusual energy, or changed behaviour — even if those periods felt positive rather than problematic. If you have old medical records, school records mentioning mood or behaviour changes, or letters from family members describing mood episodes, these can be genuinely useful. Note any medications you have tried and whether they made your mood better, worse, or caused unusual reactions (particularly antidepressants that made you feel "too good" or caused agitation). Family psychiatric history is also highly relevant, as bipolar disorder has a strong genetic component.
Can bipolar disorder be managed without medication?
For mild Bipolar 2, some people maintain reasonable stability with intensive lifestyle management — strict sleep hygiene, stress reduction, avoiding alcohol and recreational drugs, regular exercise, and close monitoring. However, the research evidence strongly supports medication as the primary treatment for most people with bipolar disorder, particularly those with Bipolar 1 or severe Bipolar 2. The risk of serious mood episodes — particularly with the suicide risk associated with bipolar depression — means that trying to manage without medication is generally not recommended except in genuinely mild cases with very close clinical oversight. Medication and therapy together produce substantially better outcomes than either alone.
