What This Helps Measure
Patient-facing Mood Disorder Questionnaire route used when bipolar-spectrum illness is part of the differential.
Which theories this can evaluate
- Sensory or Cognitive Overload:ADHD, autism, masking, stress load, burnout, or hypervigilance can create a fog pattern driven by saturation rather than pure depletion.
What It Does Not Prove
A screening score can support a discussion, but it does not confirm a diagnosis on its own.

Preparation, interpretation, and clinician next step for MDQ.
Visual Guide
How To Prepare
- •Confirm timing (fasting vs non-fasting) with your clinician or lab before the draw.
- •Bring your medication/supplement list and note recent illnesses.
- •Use the same lab when possible for trend consistency.
How To Discuss This Measurement
Could we use an MDQ screen as part of the bipolar-spectrum discussion instead of assuming this is unipolar depression?
How To Use This Test Well
Step 1
Book correctly
Request MDQ with required timing/prep (fasting and time-of-day when relevant).
Step 2
Capture the result exactly
Save numerical value, units, lab reference interval, and collection time.
Step 3
Interpret with pattern context
Compare results against symptom timing and related markers before changing plan.
What To Watch For
- →Lab reference ranges and optimal targets are not the same concept.
- →Recent illness, menstrual phase, sleep disruption, and medications can shift values.
- →Trend over time often matters more than one isolated value.
Result Context
normal
Within lab range; compare with your target context (Positive / negative screen context).
Result may be acceptable but still needs symptom correlation and trend review.
borderline
Near thresholds or inconsistent with symptoms.
Consider repeat testing, timing factors, and related markers before conclusions.
abnormal
Outside expected range or clearly discordant with baseline.
Use clinician-guided follow-up and structured differential workup.
What To Do Next
- •Save the result with date and symptoms from the same week.
- •Review alongside related tests instead of interpreting in isolation.
- •Use one concrete next step in your panel plan.
