Summary

This trial looks at if light therapy can treat bipolar type II patients who are relapsing into depression in autumn/winter.

Who is the study for?

This trial is for individuals with Bipolar Type II disorder experiencing a depressive phase, as defined by specific clinical scales. They must have symptoms that started in autumn or winter and be willing to consent to the study. Excluded are those with other psychiatric conditions, unstable medical issues, certain vitamin deficiencies, risk of light-induced mania or migraines, pregnancy without contraception, severe eye diseases, substance abuse problems, or past light therapy use.

What is being tested?

The study tests the effectiveness and safety of bright versus dim light therapy using Northern Light Technology lamps on patients with Bipolar Type II depression during fall/winter months. Participants will receive either bright light-therapy or dim light-therapy to determine if there's an improvement in their depressive symptoms.

What are the potential side effects?

Potential side effects may include eyestrain, headache, irritability or agitation due to exposure to bright/dim lights. There's also a risk of inducing hypomanic or manic episodes in susceptible individuals.
