Thanks for contacting HCM I am sorry to hear that you Grandmother suffered a mild stroke and left her with left sided weakness. I am glad to hear that she has returned home and is working with therapies to help regain her strength. With time she will improve but it is a long and difficult course. In addition to the therapy she is getting family members should also become involved and aid in her rehab by helping her with the exercises she has been assigned. She should be up walking as much as possible and she should be using her hands as much as possible. In my practice I have patients up walking as soon as possible and also have them playing games that require them to use their minds and fingers. To prevent further strokes keeping her blood pressure control is very important and home monitoring with blood pressure cuff will help. She may also have been placed on a anticoagulant like aspirin or Plavix. Some studies show using cholesterol lowering medication may help open blocked arteries and improve blood flow. In the US we do have rehabilitation hospitals but they require additional referrals. I recommend you talk with her doctors and see if she is a candidate for a more intensive rehab program. Hope this answers your question. Please contact HCM again for your health care questions
