Sleep Quality Directly Effects How Often You Get Migraines (1)

Tests conducted by researchers at the University of Mississippi, U.S.A have shown a strong correlation between poor quality of sleep and the frequency of migraine episodes as well as the disabilities that go with the condition.

The Pittsburgh Sleep Quality Index (PSQI) was employed in the study which tested 78 migraineurs and 208 non-migraineurs who formed the control group.

The PSQI is a tool in the form of a scoring but subjective questionnaire developed by the Sleep Medicine Institute of the University of Pittsburgh. It has questions within it’s 7 broad components on which a patient is scored, viz;

  • Subjective Sleep Quality,
  • Sleep Latency,
  • Sleep Duration,
  • Habitual Sleep Efficiency,
  • Sleep Disturbance,
  • Use of Sleep Medicines,
  • Daytime Dysfunction.

Todd Smitherman and his team found that sleep quality was significantly worse for those experiencing episodic migraines than for those in the control group. The migraining group scored an average PSQI of 8.90 as compared to 6.63 in the control group. A PSQI score more than 5 is considered significantly bad.

Factors such as depression, anxiety were adjusted for the regression analysis calculations but still it accounted for 5.3% and 5.8% of unique variance in headache frequency and disability, respectively, which the researchers say is a modest but non-trivial amount. Even when depression and anxiety factors after poor sleep quality were included in the calculations the affective symptoms did not significantly improve these analysis models beyond that of sleep quality alone which made sleep quality almost an independent and very relevant factor in assessing headache frequencies and related disabilities.

As per Smitherman, “As such, sleep quality should be assessed preferentially to other sleep disturbance variables when subjective self-report measures of insomnia are used. In light of the present findings, conclusions from systematic reviews, and practice guidelines, the most potent means of improving sleep quality and insomnia among migraineurs is likely a treatment package that incorporates stimulus control and/or sleep restriction in addition to basic sleep hygiene education and management of comorbid psychiatric symptoms.” (2)
