Multiple sclerosis, or MS, is a progressive disease characterized by the degradation of the nerves that send and receive messages between the brain and spinal cord. According to the National Institute of Neurological Disorders and Stroke, this autoimmune disorder affects between 250,000 and 350,000 people in the United States. The early symptoms of MS can be difficult to detect in some patients but should be discussed with a doctor if they occur.
Numbness or Tingling
Numbness and tingling are the most common early symptoms of MS and occur in over half of patients with this disease, explains the Multiple Sclerosis Foundation. These sensations typically arise within the feet or legs but can affect any region of the body. Numbness or tingling can be uncomfortable and may affect a patient's ability to move about normally. During the early stage of MS, these symptoms can occur intermittently but become progressively worse as the disease advances.
Decreased Vision
Vision problems occur as the first symptom of MS in approximately 15 percent of patients, explain health officials with the NINDS. Initially, patients can develop blurred or cloudy vision in one or both eyes. In certain instances, affected patients may progressively lose vision in one or both eyes, which can make it difficult for them to move about without assistance. Additionally, certain patients can experience eye pain in conjunction with vision loss symptoms. During the later stages of MS, vision symptoms may completely resolve in some patients. Patients who develop vision problems should seek immediate medical care from a doctor.
Muscle Weakness or Spasms
Patients with MS can experience unusual sensations of muscle weakness or spasms as an early symptom of the disease. Abnormal muscle spasms affect approximately 40 percent of patients, according to the University of Maryland Medical Center in Baltimore. These symptoms typically arise within the legs or hands but can affect any region of the body. Patients who develop muscle weakness may experience poor motor coordination and can have difficulty standing or walking normally.
Fatigue
Excessive fatigue can occur as an early symptom of MS in approximately 20 percent patients, warns the UMMC. As the disease progresses, nearly all MS patients develop symptoms of fatigue. Increased fatigue can make it difficult for a patient to remain alert and focused throughout the day and may cause decreased productivity at work. Affected patients may need to take frequent naps throughout the day to remain energized. Symptoms of fatigue often accompany other early symptoms of MS, such as muscle weakness or tingling sensations.
