Early, late FAP stages distinguished with noninvasive nerve fiber test

A noninvasive test that measures axonal excitability, or the processes that underlie electrical impulses along nerve fibers, could distinguish between the early and later stages of familial amyloid polyneuropathy (FAP), a study reports. “Axonal excitability has utility to identify early and progressive nerve dysfunction in [FAP],” the researchers wrote…

Pain High Among Quality of Life Hindrances in FAP, Study Finds

The progressive nature of hereditary transthyretin amyloidosis polyneuropathy (hATTR-PN), also known as familial amyloid polyneuropathy (FAP), limits patients’ health-related quality of life across all measures, with pain a particular problem, and is linked to depression or anxiety in carriers, a study from Portugal found.
