HEARING impairment may increase the risk of developing Parkinson’s disease, with every 10-decibel increase in hearing loss associated with a 57% higher risk.
A study led by Lancaster University explored whether sensory impairments, such as hearing loss, could serve as early indicators or risk factors for Parkinson’s disease, the fastest-growing neurological condition globally. In the UK, over 153,000 people currently live with Parkinson’s, and 1 in 37 individuals are expected to receive a diagnosis in their lifetime. This research adds to the growing evidence that hearing impairment is linked to broader neurological health issues.
The study utilised data from the UK Biobank, a biomedical database containing health information from 500,000 participants. Researchers analysed 159,395 individuals who had completed a speech-in-noise hearing test and had no prior history of Parkinson’s. Over a median follow-up period of 14.24 years, 810 participants were diagnosed with Parkinson’s. Statistical modelling revealed a 57% increase in Parkinson’s risk for every 10-decibel decline in hearing ability. However, when hearing loss was categorised using standard thresholds, the results were less clear, suggesting the need for further research.
While the study highlights a strong association, it remains uncertain whether hearing loss directly contributes to Parkinson’s or if both conditions share an underlying neurological cause. These findings underscore the importance of considering auditory health in the care of patients with or at risk of Parkinson’s disease. The integration of hearing assessments into Parkinson’s diagnosis and management could enhance outcomes by identifying potential risks earlier and improving quality of life.
Further research is needed to confirm these findings in diverse populations and to determine whether interventions targeting hearing loss might reduce Parkinson’s incidence. For now, the study reinforces the value of adopting a holistic approach to neurodegenerative disease care, addressing sensory impairments alongside other clinical factors.
