One week before his brother's formal diagnosis with familial amyloidosis in 2014, Vince O'Donnell discovered he carried the genes that predisposed him to familial amyloidosis polyneuropathy (now known as hereditary amyloidosis polyneuropathy) with cardiomyopathy.
Compared to his brother, Vince's diagnosis was early. To slow development of his disease, Vince started treatment on diflunisal, and he continues to take the anti-inflammatory tablet twice a day. And, with his doctor's blessing, Vince also takes green tea extract.
