My father in law, my husband and now my son have all had a stroke like episode in their 30 s. all had severe headache, lack of balance, numbness, vision blurring... it was 30+ years in between each of their episodes. My husband was misdiagnosed with MS in the late 1980 s. ten years later he had a second episode and was told he had vertebral artery dissection and not MS. My grandson is nine years old and complains of a sore stiff neck. This seems to be genetic or hereditary. How do we begin to put into place a plan to help my grandson to not have to go through what the others have gone through?
