This document discusses language disorders including aphasia and dyslexia. It defines language disorder and notes that it can affect speech, listening, reading, writing and signing abilities. It then describes different types of aphasia including receptive aphasia, expressive aphasia, and global aphasia. Dyslexia is defined as a reading disability that can result from brain injury, degeneration, or developmental issues. Adult dyslexia is linked to lesions in the visual association cortex or corpus callosum. Specific manifestations of different language disorders are also outlined.

1. V. Exceptional
Development:
Aphasia and
Dyslexia

2. Language Disorder refers to any systematic
deviation in the way people speak, listen,
read, write or sign that interferes with their
ability to communicate with their peers
(Crystal, 1987 as cited by Piper, 1998).
Language Disability affects the structure, content
and even the use of language.
Deafness is a physical impairment that causes
language disorder.

3.  language impairment that is caused by specific
brain damage
 the loss of ability to use and understand language
Categories of Aphasia
- Receptive Aphasia
- Expressive Aphasia and
- Global Aphasia

4. also referred to as sensory aphasia or “Wernicke’s
aphasia”
Manifestations:
- repeated patterns in speech
- odd combination of words
- problems in retrieving words from memory

5. also called as motor aphasia or “Broca’s aphasia”
Manifestations:
- slow and labored speech
- no difficulty in comprehension

7. combination of receptive and expressive aphasia
sometimes referred to as irreversible aphasia
syndrome (Piper, 1998)
Manifestations:
- limited comprehension
- speech is minimal

9. defective reading or severe reading disability
represents loss of competency due to brain
injury, degeneration, and developmental failure
to keep pace with reading instruction
Brain area:
Adult dyslexias result from lesions in
the visual association cortex or the
corpus callosum.

10.  Adult who could write but not read
 An adult suffers from lesion that involves the
medial and inferior aspects of the left occipital
lobe and the splenium of the corpus callosum

11.  seen in adults with occipital lesions where
letters similar in configuration are mistaken
from another
Ex. m and n or k and x
 associated with occipital lesions where
patients could easily recognize letters
but could not grasp the whole words

12.  means inefficient recognition or loss of the
ability to recognize objects
 patients can read but throw a slow,
letter by letter analysis of a word

14. The End
Thank you for
listening.
