Common sign linked to old age could be a symptom of Parkinson's (Hearing loss)

Common sign linked to old age could be a symptom of Parkinson's

 

So 1 in about 200 of the original sample risk getting Parkinsons 14 years later. (Rounding figure above to 800 of 160,000 is 1 in 200ish)

They say there’s a 57% increase in risk for those who had hearing loss ( sounds very scary ) but actually that would mean those with hearing loss would be something like 1.57 in 200 people? (Am I doing the sums right?)

So risk changes from 0.5%
(of original sample)

to 0.78%
(portion of sample that had hearing loss & 14 years later got Parkinsons).

Might the ones with hearing loss also be older? Does risk of Parkinsons increase with age?

 

They seem to have dealt with that in the study:

Speech-in-noise hearing impairment is associated with increased risk of Parkinson's: A UK biobank analysis, 2025, Readman et al

Edit: More details

 

I think this is a mistake. The 1.64 figure isn't within the confidence interval. I'm guessing just extra zeros added in the text.

 

Ah good. I was just looking at the abstract.
