I am 65 years old and have been using hearing aids for the last 10 years. However, now I find it difficult to hear and distinguish between words. What should I do?

You need to undergo a thorough audiological examination. An unaided (without hearing aids) and aided pure tone audiogram should be done. In addition to this, you should also get a speech discrimination testing done. Depending on the results of the tests, the cochlear implant team could decide whether you would be a likely candidate for a cochlear implant.
