Multiple sclerosis (MS) is a lifelong disease. Although its symptoms can come and go, there is no cure. Some people have more frequent and severe attacks of symptoms. The future for people with MS has improved a lot, thanks to new medicines. Today, most people with MS are still able to walk 20 years after they're diagnosed.
People with Guillain-Barré syndrome (GBS) can have severe symptoms, but they usually make a full recovery. GBS often gets better after a few weeks, but the weakness it causes can continue for years. Sometimes, the numbness and tingling will come back years after the first attack of symptoms.
