Overview
A healthcare provider will diagnose idiopathic hypersomnia after a physical exam and testing. During the exam, your provider will learn more about your symptoms. They may ask you to rank how sleepy you are by answering questions on the Epworth Sleepiness Scale assessment.
You may also need to keep a sleep journal for several weeks, to keep track of when you fall asleep and wake up. Your provider might also ask you to wear an actigraph device, which can record sleep times for you.
Testing may include sleep studies like a polysomnography or a multiple sleep latency test. Your provider will review your sleep study results and run additional testing to rule out conditions with similar symptoms.
