Multiple seals

Multiple sclerosis is a neurological disorder that affects the brain, spinal cord, and optic nerves. Symptoms vary from person to person, but may include vision problems, muscle weakness, balance and coordination problems, and difficulty with speech and swallowing. The disease is characterized by the formation of lesions or plaques on the brain and spinal cord. These plaques can cause the nerves to become inflamed and damaged, leading to a wide variety of symptoms. The severity and type of symptoms can vary greatly, depending on the location and number of lesions.
