Adults and children with migraines may also have lower quality and lower REM sleep than those without migraines.
A recent study also found that children with migraines get less total sleep time than healthy peers, but take less time to fall asleep, according to a meta-analysis published in Neurology, the medical journal of the American Academy of Neurology.
Rapid eye movement (REM) sleep is defined as the stage of sleep that involves most brain activity and lucid dreams, and is an important stage for learning and memory function.
“Does migraine cause poor sleep quality or does poor sleep quality cause migraines?” said meta-analysis author Jan Hoffman, MD, from King’s College London and a member of the American Academy of Neurology. Explain how migraines affect people’s sleep patterns and the severity of their headaches. In this way, clinicians can support migraine sufferers and provide more effective sleep treatments.”
The meta-analysis included 32 studies, involving 10,243 people. Participants completed a questionnaire to assess their sleep quality. They asked about sleep habits, including how long it takes to fall asleep, total sleep time and use of sleep aids. Higher scores indicate worse sleep quality.
For many of the studies, people participated in a nighttime sleep lab used to diagnose sleep disorders.
This sleep study records brain waves, blood oxygen level, heart rate and eye movement.
The researchers found that adults with migraines, in general, had higher average scores on the questionnaire than those without migraines, with a moderate amount of difference due to migraines.
The difference was greater for those with chronic migraines.
When the researchers looked at sleep studies, they found that adults and children with migraines had less REM sleep as a percentage of their total sleep time than their healthy counterparts.
When looking at children with migraines, the researchers found that their overall sleep time was shorter, their waking time was longer, and they had less time to start falling asleep compared to children without migraines.
It’s possible that children with migraines sleep faster than their peers because they may be sleep deprived, Hoffman said.
“Our analysis provides a clearer understanding of migraines and how they affect sleep patterns and demonstrates the impact of these patterns on a person’s ability to get a good night’s sleep.”
A meta-analysis does not prove a causal relationship between sleep and migraines. One limitation of this study is that drugs that affect sleep cycles were not taken into account.
