actress christina applegate has
multiple sclerosis (ms)
, she revealed on twitter on tuesday. she was diagnosed “a few months ago,” she wrote. “it’s been a tough road. but as we all know, the road keeps going.”
ms is a chronic autoimmune disease that affects the brain and spinal cord. essentially, the immune system attacks the protective covering of nerve fibres, which can cause permanent damage to the nerves. the condition also prevents clear communication between the brain and the rest of the body.
symptoms vary widely from patient to patient, and ms can present very differently in different people. some of the most common symptoms include fatigue, vision problems, difficulty walking, tremors and slurred speech.
ms flare-ups, when symptoms are severe, can vary a huge amount in length — sometimes they last months, sometimes just days.
and the disease itself also evolves frequently,
according to healthline
. the most common type at the onset of the disease is rrms, a cycle of relapse and remission. primary progressive ms (ppms) involves short periods of stability, and secondary progressive ms (spms) is when rrms transitions into progressive ms.
experts still don’t know what causes ms. there is no cure, but there are treatments that can help manage symptoms. corticosteroids are sometimes prescribed to reduce nerve inflammation, and if that doesn’t work, doctors may attempt a plasma exchange, where the liquid part of the blood is separated from blood cells and mixed with a protein solution before being put back in the body. injections and oral medications are sometimes prescribed to help slow the disease’s progression.
