Recently, prevalence of the migraine has shown a significant increase. It is more common in women than in men due to hormonal factors as well as sensitive and emotional mood of women. Other factors are socioeconomic status, obesity, unhealthy nutrition and stress. Though migraine is most common between the ages of 18 and 45, it may affect both men and women over the age of 45.
Migraine is characterized by interpersonal variations. If the attacks persist despite prophylactic treatment, treatment of chronic migraine is employed. Today, Botox is an effective treatment modality for the chronic migraine. In this method, the aim is to reduce muscular activity through injection of a substance called Botulinum toxin. When the activity of muscles is reduced, the pain felt by the patients also decreases.
Botulinum toxin is injected into 31 locations in muscle groups in seven different areas. While it is injected more intensely into the more stiff muscles, less amount of Botulinum toxin is injected into the less stiff muscle groups. This treatment is given in 3 to 5 cycles at quarter intervals. Though not all patients with migraine are good candidates for this treatment, it is an optimal modality for the patients with chronic migraine disease.
