Fatigue is a common and debilitating symptom of multiple sclerosis (MS), a disease of the central nervous system.
A study published in February 2014 suggests that sleep apnea is common in people with multiple sclerosis and may contribute to their overall fatigue.
The study included 195 participants who all had MS. They were asked to take a sleep questionnaire about daytime sleepiness, insomnia, sleep apnea, and fatigue. Sleep apnea occurs when the soft tissue at the back of the throat relaxes and can cutoff the airway. People with sleep apnea often snore loudly and may wake up often throughout the night.
The study suggests that sleep apnea may be an under-diagnosed but rather common contributor to the fatigue experienced by MS patients.
Sleep apnea is diagnosed via a sleep test. Once diagnosed, patients may be put on a respirator that helps keep airways open.
