I know sleep apnea is one of the most common causes of hypersomnia, but I'm wondering if there are any others. What can case hypersomnia? How do different causes change the treatment?

You're right! Sleep apnea is the most common cause of excessive daytime sleepiness. However, restless leg syndrome, or any disorder that disrupts your sleep, can cause daytime sleepiness.
