Poor sleep is common in MS
Sleep is a very important part of healthy living but there is no set rule on how much sleep is needed. Some people manage perfectly well on four or five hours, whilst others need eight or more.
During sleep there are many complex and important processes going on in the body that allow people to wake up the next day feeling refreshed. Not getting enough sleep leads to lack of energy, irritability and decreased concentration, attention, memory and motivation.
Problems getting enough high quality sleep are common in the general population. This study looked to see what proportion of people with MS experienced poor sleep and what factors led to sleep difficulties.
How the study was carried out
90 people with MS, who had been diagnosed for between 13 to 18 years, and 108 controls, matched for age and sex, took part in the study. They answered a postal questionnaire about sleep called the Pittsburgh Sleep Quality Index (PSQI). It asks general questions about sleep over the last month including:
- What time do you usually go to bed?
- How long does it usually take you to fall asleep?
- How many hours of sleep do you get (not always the same as the number of hours in bed)?
There are also questions about how often someone has difficulty sleeping, the quality of their sleep and the difficulties they may face because of sleep problems such as when driving or socialising. Their room mate or bed partner also completes questions about how much they have noticed them snoring, twitching and having restless sleep. Each question on this section of the questionnaire has four different answers to choose from ranging from "no problem" to "a very big problem".
The answers to all the questions are scored in seven categories to give an estimate of various sleep characteristics such as sleep quality or disturbance and the effects on daytime activities. The seven scores are added together to give the global PSQI score. Participants in this study were separated into good sleepers and poor sleepers based on their global PSQI score.
The researchers also noted whether someone used medication (especially disease modifying therapy or antidepressant drugs) and measured daytime sleepiness, pain, depression and fatigue using appropriate questionnaires. Quality of life was measured using a questionnaire called the Multiple Sclerosis Impact Scale (MSIS-29).
What was found
Participants with MS had an average age of 45 which compared well with the controls (average age 44). Pain, fatigue and depression were common in people with MS. 35 people with MS (43%) received disease modifying therapy (beta interferon, glatiramer acetate or natalizumab).
The researchers found that, on average, people with MS had a higher global PSQI score indicating a poorer quality of sleep. In addition, they found that 67% of people with MS were classed as poor sleepers compared with 44% of the controls. The main factors associated with sleep disturbance were pain and fatigue and it was more common in women. People with MS who had moderate depression and those on antidepressant medication, all experienced poor sleep. In addition, using disease modifying therapy or having a reduced quality of life was associated with poor sleep.
What does it mean?
Poor sleep is common in people with MS. The researchers suggest that it is important to identify sleep problems early and to treat the contributing factors, such as pain, where possible.

More about sleep and MS
This study adds to the evidence that people with MS often experience sleep problems. It highlights the importance of getting treatment for symptoms that may contribute to poor sleep. Common ones are pain, depression, spasms and bladder problems. If injecting one of the disease modifying therapies leads to poor sleep, it may help to change to a different time of day. You can read more about the causes of sleep problems in the A to Z of MS.
Better treatment for troublesome symptoms may help but there is often scope for other changes. For example, having a better bedtime routine so that you are as relaxed and ready for sleep as possible. We have some tips for better sleeping and NHS Choices also offers suggestions on better sleep.
