This document discusses different types of speech disorders including aphasia, dysphonia, dysarthria, and others. It provides details on aphasia including the major divisions of fluent and non-fluent aphasia. Specific types of aphasia like Wernicke's, Broca's, conduction, and global aphasia are explained. The document also covers dysarthria and dysphonia as well as other miscellaneous speech disorders.

4. APHASIA
• Aphasia is defined as an acquired impairment
in the use of language due to damage to
certain parts of the brain
• This damage could be caused by injury,
stroke, or seizures
• The language deficits include difficulties in
language comprehension and execution

6. MAJOR DIVISIONS OF
APHASIA
• Fluent aphasias/Receptive aphasia
– The inability to understand the language of others and the
production of less meaningful speech then normal. eg; wernicke”s,
transcortical sensory,conduction,anomic
• Non-fluent aphasias/expressive aphasia
– Difficulty producing fluent, articulated, or self-initiated speech.eg;
Broca”s, transcortical motor,global
• Pure aphasia
– are selective impairments in reading, writing, or the recognition of
words. These disorders may be quite selective. For example, a
person is able to read but not write, or is able to write but not read.
Examples of pure aphasias are
– : Pure Alexia, Agraphia,Pure word deafness
Page 6

7. Types of Fluent Aphasias
• Wernicke’s aphasia
– People with this type of aphasia- JARGON
APHASIA, have difficulty or inability
understanding others speech, and produce
meaningless speech
– FLUENT,VOLUMINOUS SPEECH
– NEOLOGISMS
– SYMANTIC-”sister for mother”
– Insight is ABSENT
– produced by damage to Wernicke’s area of
the brain-division of middle cerebral artery

8. WERNICKE”S APHASIA
Page 8

9. More Types of Fluent Aphasia
• Conduction aphasia
– The main symptom of this type of aphasia
is difficulty repeating something someone
has just said
– FLUENT SPEECH, but paraphasic
– COMPREHENSION INTACT..
– REPETITION,NAMING,WRITING IMPAIRED
– FILLED PAUSES-Aaaa….Aaaaa
– damage to the ARCUATE FASICULUS
Page 9

10. More Types of Fluent Aphasia
• Anomic aphasia/minimal
dysfunction syndrome/nominal
aphasia
– This aphasia is characterized by difficulty
finding names and difficulty substituting
indefinite nouns and pronouns with
substantive words. For instance, people
with this affliction will use words like,
thing, stuff, or it instead of automobiles,
groceries, or furniture.
– Primary deficit is WORD FINDING AND
NAMING
– SINGLE MOST COMMON LANGUAGE
DISTURBANCE IN HEAD TRAUMA AND
ALZHEIMER”S D/S Page 10

11. FLUENT TRANSCORTICAL/
TRANSCORTICAL SENSORY
APHASIA
• Similar to WERNICKE”S APHASIA but
REPETITION IS INTACT
• They can repeat but cant understand it
Page 11

12. Non-Fluent Aphasias
• Broca’s aphasia
– This type of aphasia manifests with difficulties
initiating well-articulated conversational speech
– NON FLUENT, EFFORTFUL,slow, labored, and
agrammatical speech, which means words like a,
an, or the and verb tense is left out of their
speech…incomplete speech
– Insight is PRESENT
– Additional defects?
– damage to Broca’s area of the brain..superior
div. of middle cerebral artery
Page 12

13. BROCA”S APHASIA
Page 13

14. More Types of Non-Fluent
Aphasia’s
– Transcortical motor aphasia
– Similar to BROCA”S APHASIA but
REPETITION is INTACT
– People with this aphasia do not speak
unless they are strongly encouraged
to do so and when they do speak it is
labored and non-fluent
– damage to the premotor cortex
anterior and superior to Broca’s area…
anterior cerebral artery
Page 14

15. More Types of Non-Fluent
Aphasia’s
• Global aphasia
– As the name suggests, this type of aphasia is
characterized by a severe depression of all
language functioning
– NON FLUENT, naming, repetition,
comprehension all impaired
– damage around and to Broca’s and Wernicke’s
areas of the brain …entire middle cerebral
artery

16. Other Interesting Facts About Aphasia
The handwriting of a person with an aphasia
reflects their speech impediment.
There was an experiment done where people
with Broca’s and Wernicke’s aphasias were
presented with a picture and then asked to
write down a description of what they say in
the picture.
Page 16

17. This is the picture
Page 17

18. A patient with Broca’s aphasia wrote
this
Notice the use of very few words, but
the words do make some sense
Page 18

19. A patient with Wernicke’s aphasia
wrote this
Notice here that there are many, less
forced, words, but they don’t make
much sense. Also because they’re not
struggling to find their words, the
handwriting is better Page 19

• Is due to defect IN ARTICULATION.
• LANGUAGE CONTENT IS NORMAL
• TYPES- 4

23. DYSPHONIA
• Is due to defect in the production of
sound
CAUSES
1) Laryngeal diseases-eg;laryngitis
2) Vocal cord lesions
3) Xth cranial nerve palsy
4) hysterical

24. OTHERS
1) Cluttering
2) Stammering
3) Dysprosody-in parkinsonian disease
4) Scanning
5) Staccato-each syllable is uttered
seperately
