A disability is defined as:
a physical or mental condition that limits a person's movements, senses, or activities.


Abstract:

Abstract Diabetes mellitus is considered a risk factor for sensorineural sudden deafness . Its pathogenesis remains unknown . However , the physiopathological implication of a hyperviscosity syndrom in diabetics and patients bearing of sudden deafness can mean the nexus between the two entities . Total blood viscosity and erythrocyte adhesion were haemorheological parameters significatively higher in blood of diabetics with sudden deafness than in normal hearing controls . Moreover , erythrocyte filterability and deformability were lower in diabetics , but it was not statistically significative . These findings help to guide therapy in these patients towards specific measures to improve blood viscoelastic properties .
