Scientists from the University of California conducted a study that showed a connection between multiple sclerosis and insomnia. There were 2,300 people with multiple sclerosis and 70% of them had a sleep disorder.
Along with feeling tired (a distinctive feature of multiple sclerosis) a person can’t fall asleep for at least 30 minutes. They often have to take pills to fight their insomnia. People aged from 20 to 50 are in the risk group.
