My mom is on it for parkinsons. It increases the level of dopamine in the brain. Be careful though, as dopamine that is too high is what causes schizophrenia. Pay careful attention and ask those around you to pay careful attention to whether you seem "spaced out" or start imagining things that aren't there...it could be a sign your dose is too high. We had to cut my mom back from her original dosage because she started having all kinds of delusions and hallucinations. Your doctor is doing it right by starting low and increasing slowly.
