Formula Used

This calculator uses a weighted comparison model. It does not diagnose illness. It estimates which pattern looks more similar to the input profile.

Bipolar I score emphasizes mania duration, psychosis, hospitalization, impairment, reduced sleep, risky behavior, switching frequency, depression burden, family history, and lower recovery.

Bipolar II score emphasizes hypomania duration, depression burden, switching frequency, better recovery between episodes, reduced sleep, impairment, family history, lower psychosis loading, and lower hospitalization loading.

Normalization rules: mania days are capped at 14, hypomania days at 14, depression days at 90, psychosis and hospitalizations at 3, and mood switches at 12.

Interpretation rule: a score gap of at least 10 points creates a leaning. Smaller gaps are labeled mixed or closely balanced.

How to Use This Calculator

  1. Estimate the number of days linked to mania, hypomania, and depression.
  2. Enter the count of psychosis episodes and hospitalizations.
  3. Rate impairment, sleep reduction, risky behavior, and recovery on a 0 to 10 scale.
  4. Add the yearly mood switching estimate and family history flag.
  5. Press Compare Patterns to see scores, the difference index, and the graph.
  6. Export the result as CSV or PDF for records or discussion.
  7. Use results only as structured educational support, not diagnosis.

Pattern Comparison Guide

Why compare the two patterns?

Bipolar I and Bipolar II can share mood cycling, sleep change, distress, and functional disruption. The major pattern difference is not simply feeling better or worse. It often involves episode type, severity, psychosis, hospitalization, recovery, and how long mood states persist.

Why these inputs matter

Longer manic periods, stronger impairment, psychosis, and hospitalization usually push a profile toward Bipolar I style patterns. Recurrent depression, shorter elevated states, preserved recovery, and lower psychosis loading often push a profile toward Bipolar II style patterns.

How to read the scores

The scores are comparison scores, not prevalence scores. A higher Bipolar I value means the entered profile resembles weighted Bipolar I markers more strongly than weighted Bipolar II markers. A higher Bipolar II value means the opposite. A small gap signals overlap.

Clinical caution

Real diagnosis depends on full symptom history, duration rules, substance effects, medical causes, safety risk, trauma history, and clinician judgment. This page can help structure observations before a professional visit, but it cannot replace assessment, diagnosis, or treatment planning.

FAQs

1. Is this calculator diagnostic?

No. It is an educational comparison tool. It organizes episode features into weighted scores so users can discuss patterns more clearly with a qualified clinician.

2. Why is psychosis weighted more for Bipolar I?

Psychosis and marked severity are more commonly associated with Bipolar I presentations. The calculator uses that pattern difference to separate score directions.

3. Why does depression weigh heavily for Bipolar II?

Bipolar II often includes substantial depressive burden alongside hypomanic episodes. That is why longer depression duration meaningfully lifts the Bipolar II comparison score.

4. What does a mixed or balanced result mean?

It means the submitted values do not strongly favor either weighted pattern. Overlap, incomplete data, or non bipolar explanations may be present.

5. Should I enter exact clinical durations?

Use the best available estimate. Even approximate values can help organize observations, but exact diagnosis still requires a full clinical interview.

6. Why include recovery between episodes?

Inter episode recovery can help separate severity and continuity patterns. Better recovery may support a Bipolar II style comparison in this model.

7. Can medication or substances change the result?

Yes. Sleep loss, substances, medication effects, and medical conditions can influence symptoms. That is one reason this tool should never be used alone.

8. When should someone seek urgent help?

Urgent help is important when there is suicidal thinking, psychosis, dangerous behavior, inability to function, or concern for immediate safety.
