Multiple sclerosis (MS) is the disease characterized by multiple lesions in the white matter of the brain and spinal cord. It is an autoimmune disorder where the immune system attacks the protective myelin sheath surrounding nerve fibers, leading to inflammation and the formation of scar tissue (sclerosis). This results in a variety of neurological symptoms, which can vary widely among individuals. MRI scans are commonly used to detect these lesions, aiding in the diagnosis of MS.

How brain scans detect ms?

Brain scans, particularly magnetic resonance imaging (MRI), are crucial for diagnosing multiple sclerosis (MS) as they can reveal lesions or plaques in the brain and spinal cord. These lesions are caused by the demyelination characteristic of MS, where the immune system attacks the protective covering of nerve fibers. MRI can also help assess the extent of disease progression and monitor treatment efficacy by detecting new or changing lesions over time. Advanced imaging techniques like diffusion tensor imaging (DTI) may also provide insights into the integrity of white matter in the brain.
