Abstract:
A 63-year-old patient with relapsing-remitting multiple sclerosis (MS) and comorbid liver cirrhosis presented with progressive cognitive decline, gait disturbance and elevated serum neurofilament light chain (NfL), suggesting disease progression independent of relapse activity (PIRA). Development of acute hepatic encephalopathy led to reconsideration of the cause of previous clinical worsening and MRI revealed progressive basal ganglia manganese accumulation, establishing the diagnosis of acquired hepatocerebral degeneration, retrospectively challenging the PIRA diagnosis. Careful evaluation of comorbidities is warranted in older MS patients, as progressive worsening and high NfL may indicate alternative etiologies, particularly if GFAP (glial fibrillary acidic protein) stays within normal range.

Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...
