Overview | Diagnosis | Symptoms | Treatment

The symptoms that MS patients experience depend on the area of the brain or spinal cord affected. The symptoms involve various portions of the nervous system and occur over a period of time. Demyelination in the nerve pathways that send messages to the muscles causes problems with movement (motor symptoms), while demyelination along the nerve pathways that carry sensations to the brain causes disturbances in sensation (sensory symptoms). The most common early symptoms are tingling, numbness, loss of balance, weakness, blurred or double vision. The less common symptoms may include slurred speech, sudden onset of paralysis or incoordination.

Some patients may notice that symptoms worsen or increase in frequency after an illness (such as a cold), a fever, hot bath, exercise or time spent outside on a hot day. Any symptoms related to rise in body heat might not necessarily mean that your MS is worsening. If you notice a symptom that is not affiliated with any rise in body temperature and last longer than 24 hours, you should notify your doctor.

Multiple sclerosis follows a varied and unpredictable course. In many people, the disease starts with a single symptom, followed by months or even years without any further symptoms. In others, the symptoms become worse within weeks or months. It is important to understand that although a wide range of symptoms can occur, a given individual may experience only some of the symptoms and never have others. Some symptoms may occur once, resolve, and never return. Since MS is such an individual disease, it is not helpful to compare yourself with other MS patients.
