- Aphasia is the loss of ability to communicate through speech and understanding, usually caused by poor brain blood flow. It affects areas like Wernicke's area, involved in language understanding, and Broca's area, involved in speech production. - Wernicke's aphasia results in fluent but meaningless speech, while Broca's aphasia causes non-fluent, labored speech. - Aphasia is diagnosed through evaluations by professionals like speech therapists, neurologists, and psychologists. Treatment requires multidisciplinary rehabilitation to stimulate language and compensate lost functions.

3. Introduction
• Language specialists distinguish speech
disorders, which include difficulties in
pronunciation and articulation, language
disorders, which are manifested by the
difficulty in finding words and phrases
• Aphasia is the total or partial loss of ability to
communicate (talk and understand) and is
usually caused by poor brain irrigation.

4. Etiology
• Some etiological factors responsible for
aphasia are:
Vascular
Tumorals
Infectious
Traumatic
Metabolic
Degenerative

5. Wernicke area
• It is located in the temporoparietal junction.
• It is responsible for understanding spoken
language.

6. Broca area
• It is located in the lower frontal gyrus
• It is responsible for providing instructions for
the production of spoken language
(movement planning for speech production
and provision of words of grammatical
function)

7. Arched fascia
• Responsible for the connection between the
areas of Broca and Wernicke.

8. Wernicke's aphasia
• Aphasia receptive or sensory or fluent.
• Inability to understand language.
• Language is fluent.
• He speaks with many functional words
and few nouns or verbs.

9. • Inability to read (alexia).
• Not knowledge of the disorder.
• Understanding, repetition, naming,
reading and writing are
compromised.
• Paranoid agitation and behavior.

10. Aphasia of Broca
• Motor or expressive or non-fluent
aphasia.
• Inability to express themselves through
spoken or written language.
• There remains the ability to understand
language and to control the muscles of
language for other purposes.

11. • She speaks not fluent, labored,
interrupted by many pauses.
• Few functional words, but many
verbs and nouns (telegraph).
• Knowledge of the disorder: tearful,
depressed and frustrated.
• Denomination and repetition.

Preserved Altered Altered Altered

13. Causes
• It is not a disease, it is a symptom;
• Usually due to neurological diseases such as a
tumor, stroke, and degenerative diseases such
as Alzheimer's;
• Accidents such as traumatic brain injury
(Epilepsy, intoxications).

14. Diagnosis
• It should be multidisciplinary and
exclusionary;
• Psychologist: Evaluates through tests and
detailed observations, performing cognitive
assessments and affective disorders;
• Speech-Language Pathologist: Evaluates
spoken language, processing of sound
elements such as phonemes and syllables;

15. • Psychopedagogue: Evaluates by means of
tests the cognition comprehension and
the performance of reading and writing;
• Neurologist: Evaluates through
neuroimaging;

16. Trataments
• It is necessary multidisciplinary therapy
intervention to work the functional
compensation of the contra lateral limb of the
injured hemisphere;
• It is performed through the stimulation of the
language and it is necessary to plan
specifically for each case;

17. • The therapist will build bridges between skills
that have remained and those that have been
lost, using the plasticity of the central nervous
system;
• Exacerbating intact brain functions to
compensate for lost functions is a good
rehabilitation strategy.

18. Conlusion
• Concluded that the treatments for aphasia
described in the literature do not indicate
superiority of a therapeutic approach on the
other, nor do they identify conditions for which
patient justifies the use of one or other specific
rehabilitation therapy.
• It should be emphasized that the theoretical-
methodological foundations are essential to
guide the therapeutic work with aphasic subjects.
