According to a study posted in Circulation: Journal of the American Cardiovascular Association.

In the full case of poor hearers, researchers discovered that the gray matter density of the auditory areas was low in people with decreased hearing ability, suggesting a link between hearing brain and ability volume. ‘As hearing capability declines with age group, interventions such as for example hearing aids is highly recommended not only to boost hearing but to protect the mind,’ said lead writer Jonathan Peelle, PhD, study associate in the Department of Neurology. ‘People hear differently, and those with also moderate hearing loss may have to work harder to comprehend complex sentences.’ In a pair of studies, experts measured the relationship of hearing acuity to the brain, first measuring the brain’s response to progressively complex sentences and then measuring cortical brain quantity in auditory cortex.Using the validation data set, we compared dosage predictions from the pharmacogenetic model with those from two other models: a clinical model that did not include genetic factors and a model with a set dose of 5 mg of warfarin each day. The scientific model was constructed with the use of the same strategies as the pharmacogenetic model, but without the incorporation of genetic variables. The following assessment of clinical significance is based on this validation data arranged except where otherwise stated. The mean absolute error and the coefficient of dedication in the validation data set were our prespecified metrics for evaluating the pharmacogenetic, clinical, and fixed-dose models.
