People tend to think that bipolar disorder is just one disorder, but it’s actually more like a kaleidoscope of different personality disorders. People who suffer from it typically have extremely elevated moods (think euphoric highs with boundless energy) but then can crash to an extremely depressed mood at various times as well. The disorder is highly unpredictable and can tap into a whole variety of emotions along the way—making it much more complicated than the simple “Jekyll and Hyde” syndrome our society assumes. The good news: Genetics play a huge role in the biology of bipolar disorder, and medications can help sufferers find more of a middle ground and avoid the extreme emotional ups and downs.
