Migraines are associated with major depression, bipolar disorder, anxiety disorders, and obsessive compulsive disorder. These psychiatric disorders are approximately 2-5 times more common in people without aura, and 3-10 times more common in people with aura.
A review on potential triggers in the indoor and outdoor environment concluded that there is insufficient evidence to confirm environmental factors as causing migraines. They nevertheless suggested that people with migraines take some preventive measures related to indoor air quality and lighting
The traditional science of Ayurveda considers headache to be caused because of two primary reasons – a sensitive nervous system and impaired digestion. Improper diet and lifestyle causes aggravation of Pitta (Ayurvedic humor representing Fire) in the body. In an aggravated state, Pitta impairs digestion, leading to production of digestive impurities (known as ama). This ama gets stored in the manovahi strotas (mind channels), thereby becoming the cause for headaches.
A sensitive nervous system lowers the ojas (energy) in the body. Ojas is the essence of all body tissues and provides strength to the nervous system and body. If you have a strong nervous system, you are able to fight against problems and carry on with your work with a healthy mind. Lowering of ojas causes migraine-like problems.
Ayurvedic treatment of a headache does not focus on simply alleviating the pain but aims at treating the root cause. Herbal preparations are administered to balance aggravated body energies and restore the digestive function.
Preventive treatments of migraines include medications, nutritional supplements, lifestyle alterations, and surgery. Prevention is recommended in those who have headaches more than two days a week, cannot tolerate the medications used to treat acute attacks, or those with severe attacks that are not easily controlled.
The goal is to reduce the frequency, painfulness, and/or duration of migraines, and to increase the effectiveness of abortive therapy. Another reason for prevention is to avoid medication overuse headache. This is a common problem and can result in chronic daily headache.
