I was not offended at all. I was just clarifying for you. What you say is remission is a normal stage in this disease. There are different types of MS and the most common form (upon initial diagnosis) is relapsing-remitting. That means there are times when the progression of the disease has stopped for the time being. That stage of remitting or remission, unfortunately, does not last. MS, for most of us, comes in cycles which can result in an increase in symptoms and disability.
I am very sorry to hear about your brother. Many of us suffer from the inability to walk without looking drunk. Does your brother have an official diagnosis? If he does, he may want to carry his doctor's business card or a short letter verfying his condition so he can explain his gait problems more easily. Some people with MS also have slurred speech. This can cause the same problem.
Love and prayers,
