ABSTRACT
Background: Aphasia is a language disorder caused by brain injury;
one aspect that has been investigated is whether there are alterations
in the recognition of non-verbal language.
Objective: To determine whether there is an alteration in decoding
nonverbal sounds in patients with some form of aphasia.
Material and methods: A cross-sectional study comparing two groups of
patients in acute and chronic phase, plus a control group was conducted.
In a group of 20 aphasic patients, ages 22 and 72, it was considered
acute for those who suffered vascular event in less than one month upon
the completion of the test period, and chronic, those whose vascular
event exceeded the month. This research was conducted at the area of
Neuro Service Audiology and Phoniatrics at the General Hospital of
Mexico. The control group included 20 healthy subjects.
Results: The auditory discrimination test showed average percentages as
follows: for the control group 99.4% patients in acute phase of 58.6%
and 89.5% chronic phase. The Kruskal-Wallis and Mann-Whitney U
was used for data analysis finding a p ‹ 0.001.
Conclusions: The aphasic patients have difficulty for discrimination
particularly of not verbal language; acute patients showed more difficult
to identify non-verbal sounds. Some types of aphasia represent a major
constraint for the patient such as the anomic aphasia.
