Common Causes
- Hereditary: Features like early aging of the cochlea and susceptibility of the cochlea for drug insults are genetically determined.
- Atherosclerosis: May diminish vascularity of the cochlea, thereby reducing its oxygen supply.
- Dietary habits: Increased intake of fatty diet may accelerate atherosclerotic changes in old age.
- Diabetes: May cause vasculitis and endothelial proliferation in the blood vessels of the cochlea, thereby reducing its blood supply.
- Noise trauma: Exposure to loud noise on a continuing basis stresses the already hypoxic cochlea, hastening the presbycusis process.
- Smoking: Is postulated to accentuate atherosclerotic changes in blood vessels aggravating presbycusis.
- Hypertension: Causes potent vascular changes, like reduction in blood supply to the cochlea, thereby aggravating presbycusis.
- Ototoxic drugs: Ingestion of ototoxic drugs like aspirin may hasten the process of presbycusis.
