Migraine is a medical disorder which is characterized by pain in the head (usually attack one side of the head). Usually the patient will also be sensitive to light. Depression is a mental disorder that is generally characterized by symptoms of sadness, insomnia, and fatigue.

A study conducted in Canada reveals migraine was closely linked to depression. Researchers reveal the migraine can lead to clinical depression, whereas prolonged depression can also cause migraines.

This study was written by Geeta Modgill based his observations on the data he took from The Canadian National Population Health Survey, in which these data involving more than 15,000 people. The participants then continued to be observed for approximately 13 years (1994-2007).

Overall, 15% of these participants had experienced depression, while 12% of them had experienced a migraine. Meanwhile, 22% of participants who suffer from migraines were never depressed. While the non-migraine sufferers only 14.6% have ever felt depressed. The researcher also added that a person who experienced clinical depression could be at risk of migraine by 40% compared with those without depression.

Although the results of the analysis is known that migraine and depression are closely related, researchers have not been able to prove how it is that migraine and depression may relate to one another, so that further research is still needed.
