Ever wondered why people with bipolar disorder swing between mania and depression? Scientists just found out it might be all about two internal brain clocks! One is your regular sleep-wake cycle, but the other is a dopamine-driven clock that can totally mess with your mood if it gets out of sync. Basically, these clocks can team up and trigger those wild mood shifts. New treatments could target this second clock—total game changer if it works! #BipolarDisorder #MentalHealth #ScienceNews #BrainResearch #MoodSwings #Health
