HEARING LOSS IN PARKINSON'S DISEASE
European Journal of Neurology
[2014] Feb 10 [Epub ahead of print] (S.W.Lai, K.F.Liao, C.L.Lin, C.C.Lin,
F.C.Sung)
Complete abstract
Hearing loss has been found to be three times more likely in elderly
people who have Parkinson's Disease. This is partly due to the increased
prevalence of loss of hearing with age. However, hearing loss is still 1.77 times more
likely in elderly people with Parkinson's Disease than it is in elderly people who do not have Parkinson's Disease.
 Hearing
is perceived in the Cochlea, in the Organ of Corti, which is the sensory
organ of hearing.
For more information go to
Cochlea.
Dopamine, whose deficiency causes Parkinson's Disease, helps to protect against noise exposure in the
Cochlea
[1]
[2]
[3]
[4].
Insufficient dopamine can therefore lead to damage that can result in loss
of hearing.
The
cause of the increased likelihood of loss of hearing that can occur in
Parkinson's Disease is therefore originally probably biochemical rather than
structural.
