The lesions of multiple sclerosis are categorized into demyelinating lesions in the brain and spinal cord. Lesions in the brain are typically less than 1 centimeter in diameter, usually ranging from 0.3 to 1 centimeter, and are scattered around the periventricular area, corpus callosum, brainstem, and cerebellum, with a few located at the gray-white matter junction.In the spinal cord, multiple sclerosis lesions are more commonly found in the cervical and thoracic regions, exhibiting various shapes such as small scattered dots, plaques, round or oval forms, and occasionally irregular patches. Some lesions may merge and are predominantly distributed in the white matter of the spinal cord's periphery. These lesions are generally larger than 3 millimeters in diameter but rarely extend beyond two vertebral segments, with minimal spinal cord swelling.
Common symptoms include fever, fatigue, and discomfort in the affected area. Always consult with a healthcare professional for an accurate diagnosis.
Diagnosis typically involves a physical examination, medical history review, and possibly laboratory tests or imaging studies depending on the suspected cause.
Treatment options vary based on the specific condition, severity, and individual health factors. They may include medication, lifestyle changes, physical therapy, or in some cases, surgical intervention.
Seek immediate medical attention if you experience severe symptoms, rapid worsening of condition, or if self-care measures aren't providing relief within a reasonable timeframe.
