stroke with negative MRI and CT?

Hi, my husband has some neurological problems, like impaired vision, loss of concentration, and headaches. As MRI and CT screening showed no damage I stopped worrying. Do I still have anything to worry about?

Hi, some time ago my husband had blurred vision, speech disorder and poor mental capabilities. He was troubled by these symptoms every then and now for a few months, before he decided to go to see a doctor. Sometimes, he was also complaining of dizziness when getting up in the morning. But, MRI scan was negative, so at first it was considered to be result of stress and too much work. As CT scan was also negative I didn’t worry anymore. But, in two months he got a stroke. It was just then that we realized about earlier symptoms, which were indicating some disorder. Any neurological problem requires further investigation, but I believe that it is always better to take some caution measures.
