Presbycusis
- Definition
- Hearing Loss related to aging
- Epidemiology
- Onset in middle age, and slowly progressive
- Most notable over age 65 years
- Pathophysiology
- Slowly progressive Sensorineural Hearing Loss
- Typically due to atrophy of organ of corti and auditory nerve at basal end of cochlea
- Symptoms
- Abrupt high frequency Hearing Loss
- Decreased speech discrimination
- Poor understanding of speech even when loud enough
- Recruitment
- Abnormal hypersensitivity to noise
- Evaluation
- Audiometry displays high pitched Hearing Loss
- Acoustic reflex testing

|---|---|
| Definition (MSH) | Gradual bilateral hearing loss associated with aging that is due to progressive degeneration of cochlear structures and central auditory pathways. Hearing loss usually begins with the high frequencies then progresses to sounds of middle and low frequencies. |
| Definition (CSP) | progressive bilateral loss of hearing that occurs in the aged. |
