Evaluation of psychoacoustic tests and P300 event-related potentials in elderly patients with hyperhomocysteinemia.

Introduction And Objectives: Hyperhomocysteinemia as a risk factor for hearing impairment, neuronal damage and cognitive impairment in elderly patients is controversial and is limited by the small number of studies. The aim of this work was determine if elderly patients detected with hyperhomocysteinemia have an increased risk of developing abnormalities in the central auditory processes as compared with a group of patients with appropriate homocysteine levels, and to define the behaviour of psychoacoustic tests and long latency potentials (P300) in these patients.

Methods: This was a cross-sectional, comparative and analytical study.
