Migraine is believed to be a hereditary condition. Migraine is also more prevalent among women than among men. Although migraine can occur at any age, it often begins in adolescence. During advancing years, migraine generally occurs with less frequency. The duration of migraine attacks varies.
Some people have several attacks a week, while others experience it far less frequently.
The average is one to three attacks per month. Only a doctor or other qualified healthcare professional can make a true diagnosis of migraine and recommend treatment programs. Treatment plans may vary, depending on the frequency of the attacks, their causes, and whether the benefits of certain treatments outweigh the risks.
