A proper diagnostic test to diagnose Migraine disease is not available.

For example, hallucinations and visual disturbances may occur due to eye problems and might be mistaken for migraine. Since there are so many symptoms, there is always a possibility of it being wrong diagnosis.

Treatment is not required for mild or rare occurrences of silent migraine. It is commonly believed that migraine is simply a bad headache. But for many, it can be very debilitating. Migraine is actually a neurological disease, whereas headache is only one of its several symptoms. There are a number of treatments that can be used to treat silent migraine.

The cure and treatment for headache-free migraine is similar to the one for migraine headache. Patients are advised to avoid headache triggers like food, drinks and other stimulants. Doctors also advise patients to alter their lifestyle to make it stress-free and tension-free. Healthy dietary habits like consumption of high quality fish oil helps in combating nausea and inflammation and improve hormonal balance. The risk of getting inflicted with silent migraine is subdued on adopting these habits.

In case the problem persists, a doctor should be consulted immediately. Abortive drugs such as aspirins are often helpful in treating silent migraines. Beta-agonist inhalant like isoproterenol gives quick relief. To prevent migraines, calcium channel blockers are used. In certain cases, anti-seizure drugs like topiramate are also tried.

Silent migraine can be both mild as well as very severe. On experiencing the symptoms for the first time, one must visit the doctor immediately to rule out the possibility of other diseases. Once the diagnosis is confirmed, treatment can be undertaken to improve the situation.
