I'm So Worried About My Sister - She's 59 And

I'm so worried about my sister - she's 59 and her speech has been slurred for the past couple weeks.....she keeps saying it's allergies but it's not she sounds like she's drunk but she's not. Big history in our family all siblings on blood pressure medication and cholesterol - mom died of cerebral hemorrhage at age 58...it sounds like a stroke to me?
