Suggest Treatment For Migraine

I ve had MIGRAINES for 17 yrs now, progressively getting worse to the point of low avg of 5x week, with one episode resulting in a seizure 3 yrs ago. My now deceased Sister was Epileptic with Jans Syndrome. I ve had strange auras, lost time, cognitive thinking interrupted, muscle weak ess in legs to the point of collapse on at least two occasions; that at the time I attributed to medicine. Light sensitivity (fluorescent and incandescent) somewhat with natural light, but not usually unless Migrainal. My question is, SHOULD i ask my Dr to test me for Huntingdons Disease, my Uncle (mother) and his daughter also had brain cancer, both deceased from this.
