Sorry to hear about your health issues. Usually stroke signs are a sever head ache, followed by weakness on one side, facial droop on one side, vision problems, speach slur. But as I say that is usually. CT Scan and MRI are common tests to be given for diagnosis of a stroke. Echocardiogram of the heart was also done on my husband after his stroke. I believe more to ensure that his heart was healthy.
Follow your doctors orders and do what ever therapy you are prescribed by a therapist.
Stroke has no limitation on age. Even children suffer from stroke. It has nothing to do with age, although you think of more as a problem for older people because of the frequency that it strikes them.
Once you have a stroke you are under a higher risk for another. Medications can help lower that risk. Be sure to take all medication as prescribed. And try not to miss a dose.
As for can a test be done to figure out what happened that is what the CT Scan and MRI did. Ask your doctor more questions about the type of stroke. Was this a hemorage or a clot stroke? Make a list of your questions for the doctors. They will be happy to sit and slowly go over all issue you do not understand. Don't be afraid to ask, even a question you feel is dum must be asked. The more questions you ask the more you will understand.
