Cognitive impairment in liver transplanted patients with transthyretin-related hereditary amyloid polyneuropathy.

Introduction And Aim: Hereditary transthyretin-related amyloidosis (ATTR-FAP) is characterized by a progressive neuropathy, cardiomyopathy, nephropathy and ocular disease. More than 90% of amyloidogenic transthyretin is produced by the liver; however, this protein is also synthesized in the choroid plexus. Although some patients have transitory neurologic events, the impact on cognition is still unknown.
