"For yearold Lynn Kaufman the battle against migraines consumed her life. Since she was yearsold shed experienced paralyzing pain three to four times a week  each year worse than the one before. It felt as though my head was a cement block Kaufman told NBC News. It hurt to move my head from side to side my tongue felt heavy my eyes hurt my sense of smell was off. My entire head throbbed and stung. Kaufman who lives in Los Angeles visited dozens of doctors trying every option including pain clinics holistic remedies Botox shots and even hypnotherapy. Nothing helped. Finally Kaufman met neurologist Dr. David Kudrow in Santa Monica California enrolling in one of his clinical trials for people with headache disorders. Kudrow is one of hundreds of doctors investigating a new class of drugs  http block calcitonin generelated peptide CGRP a molecule that spikes during a migraine attack. The aim of the medication is to stop a migraine before it even starts. If we can block CGRP then we can abort a migraine attack says Kudrow. Its not a pill its an injection that stays in the system for a long period of time and is continuously blocking that CGRP mechanism of migraine. Results from several pharmaceutical trials are expected either later this year or in early . If approved by the FDA the drug could be available in . However the price tag could be as much as  a year. According to UCSF Medical Center https more than  million Americans suffer from migraine attacks. About  million sufferers have chronic migraine with headaches for  to  days a month. Most migraines are benign although they can be disabling. While some people are helped by overthecounter medications like ibuprofen others need prescription medications that may cause side effects such as dizziness. Kudrow says that there is a reduction in the frequency and intensity of the headaches for a large number of his patients taking the new class of drugs but not all. Another advantage it could lead to a decrease in the amount of medications used by patients to handle headaches acutely. Preliminary studies sponsored by one drug maker shows patients had three to four fewer migraine days each month. Kaufman receives regular injections once a month for the past several months and now experiences only one or two migraines a month. She feels like a different person who no longer has to shy away from social commitments. Its lifechanging Kaufman said of the new medication. The idea that I can go through life and not have that be an issue in my life is incredible."
