 
incidence accounts for  more than two-thirds of  the 
global  incidence  of  stroke  (Suwanwela  and 
Poungvarin,  2016).  According  to  the  Ministry  of 
Health data, in Indonesia, stroke is also considered 
to  be  the  leading  cause  of  death,  with  a  stroke 
prevalence of 12.1/1000 recorded in 2013. Thus, it 
can be assumed that 4 out of 1000 Indonesians are at 
risk of aphasia.  Unfortunately, Neuro-rehabilitation 
in Indonesia does not always include speech therapy. 
This is true especially in smaller hospitals or more 
remote  areas  where  stroke  is treated only  with  the 
primary  care  of  physicians.  Often,  stroke  patients 
may  receive  neither  aphasia  assessment  nor 
intervention. 
The  limited attention being paid  by linguists to 
clinical linguistics, especially language disorders of 
stroke patients (especially in Indonesia) are the main 
reason  this  research  was  conducted.  Besides, 
according  to  previous  research,  it  was  found  that 
there are language disorders suffered by people with 
aphasia. However, there is no specific note about the 
type of aphasia observed, and the linguistic disorders 
discussed are still in general aspects. Therefore, the 
objectives of the research are to analyse the types of 
aphasia  caused  by  ischemic  stroke  and  their 
modality language disorders. 
2  APHASIA 
Aphasian  said  can  be  defined  as  the  loss  or 
impairment of language caused by brain damage. In 
more  depth,  Goodglass  and  Kaplan  (1972)  define 
aphasia  as  disturbance  of  any  or  all  of  the  skills, 
association and habits of spoken or written language, 
produced by injury to certain brain areas which are 
specialized for this function. Aphasia is labelled as 
aphasic, namely a variety of limited disorder such as 
“selective  disorders  of  auditory  comprehension, 
object-naming, articulation, reading or repetition...”, 
and  these  experts  classify  alexia  with  or  without 
agraphia among the aphasias.  Schuell, Jenkins, and 
Jumenez-Pabon  (1964)  require  that  aphasia  be 
reserved  for  language  disorder  crossing  all 
modalities  –  reading,  writing,  listening,  speaking, 
and gesturing.  
Sinanović,  et.  al.  (2011)  states  that  there  are 
different definitions of aphasias, but the most widely 
accepted  neurologic  and/or  neuropsychological 
definition is that aphasia is a loss or impairment of 
verbal  communication,  which  occurs  as  a 
consequence  of  brain  dysfunction.  It  manifests  in 
impairment  of  almost  all  verbal  abilities,  i.e. 
abnormal  verbal  expression,  difficulties  in 
understanding  spoken  or  written  language, 
repetition, naming, reading and writing.  
2.1  Types and Characteristics of 
Aphasia 
Apart  from  the  broca’s  and  wernicke’s  type  of 
aphasia,  Ardila  (2014)  proposed  diverse  aphasia 
classifications  since  Broca’s  first  description  of  a 
language  disorder  associated  with  brain  pathology 
(Broca,  1863).  There  are,  however,  two  most 
influential  aphasia  classifications,  that  have 
significantly guided the area during the last decades: 
the Boston Group classification; and Luria’s aphasia 
interpretation.  The  first  one  has  been  particularly 
influential  in  the  US  and  western  European 
countries;  the  second  one  has been  mostly used in 
eastern  European  countries  and  Latin  America. 
Boston  Group  classification  represents  a  further 
development  of  Wernicke’s  ideas  about  brain 
organization  of  language,  and  includes  two  basic 
distinctions: (1) aphasias can be fluent or non-fluent; 
and  (2)  aphasias  can  be  cortical,  subcortical,  or 
transcortical  (e.g.,  Benson,  1979;  Goodglass  and 
Kaplan, 1972). Nevertheless,  this research uses the 
classification stated by Benson (1979) that classifies 
aphasia  more  in  detail,  into  global  aphasia,  broca’s 
aphasia,  wernicke’s  aphasia,  anomic  aphasia, 
conduction  aphasia,  transcortical  motor  aphasia, 
transcortical  sensory  aphasia,  and  mixed 
transcortical aphasia.  
Examination,  diagnosis,  and  treatment  on 
aphasia  patients  resulted  in  the  classification  of 
aphasia.  Some  systems  use  neurology  criteria,  in 
which  the  location  of  brain  injury  becomes  the 
condition to classify aphasia. Other systems classify 
aphasia  based  on  the  linguistic  ability  of  the 
disorder, namely The National Aphasia Association 
in  the  United  States  of  America  classifies  aphasia 
into  fluent  and  non-fluent.  In  fluent  aphasia,  also 
called  as  Wernicke’s/posterior/sensory/receptive 
aphasia,  the  language  comprehension  is  very  poor, 
but fluent in their language. Fluent aphasia results in 
long  and  unorganized  utterances,  good  articulation 
with the melody and supra-segmental characteristics 
just  like  in  normal  utterances  (these  characteristics 
may give the impression to the audience that fluent 
aphasia possesses a good linguistic ability). 
 Non-fluent  aphasia  is  also  called  as 
broca’s/anterior/motor/expressive  aphasia.  People 
with non-fluent aphasia may have difficulty in word 
production,  even  though  the  comprehension  is 
relatively  intact.  In  non-fluent  aphasia,  patients 
challenge  themselves  to  express  utterances,  unlike
