After the car accident, she developed hypersomnia that made it difficult to stay awake during the day.

The neurologist explained that several hypersomnias can present with overlapping symptoms, making diagnosis challenging.

After months of unexplained fatigue and long naps, she was diagnosed with idiopathic hypersomnia.

Recent studies have shown that idiopathic hypersomnias can severely impair daytime functioning, yet their causes remain largely unknown.

The hypersomniac intern repeatedly missed early meetings, prompting HR to arrange a medical evaluation.

Despite his best efforts to wake up on time, the hypersomniac missed three morning meetings last week.

Hypersomniacs often struggle to maintain a regular work schedule despite treatment.
