Aphasia

Aphasia

1. Can impair all aspects of communication

   • They know what they want to say, but can't always say the words correctly

2. May use "PARAPHASIAS"

   • Substitution of the words
     • Related words
     • Words with similar sound

3. Two types

   • Fluent (Receptive)
     • - Poor comprehension
     • Words with lack of meaning
     • Difficulty comprehending others
     • Unable to recognize own mistakes
   • Non-fluent Expressive)
     • Good comprehension
     • Difficulty finding words
     • Hesitation between words
     • Grammatical errors
     • Difficulty reading and writing

4. Broca's area: responsible for naming objects, and coordinating the muscles involved in speech

   • If any of this two areas suffers damage, that's when APHASIA occurs

5. Wernicke's area: Language comprehension

   • Damage in this area, impairs the ability of the brain to comprehend language
   • Left Frontal lobe

6. In most people, left hemisphere is responsible for language

   • The other hemisphere also contributes to language, enhancing the rhythm and intonation of the speech
     • These non-language areas assist people with APHASIA (sometimes)

7. Frequency

   • Approximately 1 million people in the U.S.A have it
     • Estimation of 80,000 new cases per year
   • Around one-third of the people that suffer strokes, have APHASIA.
     • More likely to suffer PARKINSON'S disease or MULTIPLE SCLEROSIS

8. Primary Progressive Aphasia (PPA)

   • Not caused by stroke or brain injury
   • Form of dementia
     • 1) Loss of language
   • The goal of treating PPA, is to maintain language function as long as possible

9. When it's caused by brain trauma or stroke, language may be improved by speech therapy

10. Brain plasticity: Brain's ability to repair itself

    • Permits brain areas that surround the brain lesion to, take over some functions during the recovery

11. People with APHASIA remain isolated because of the fear, that the other people, won't understand them or give extra time to speak.

    • By giving them the time they need, will help them to open the door of language again

12. Global APHASIA

    • Both areas have damage
      • The patient can only understand some words
      • Don't obbey comands
      • Can't name objects
      • Cannot write
