Q

If a patient can;t understand spoken word but can read as well as before, does the patient have Aphasia?

A

No. Language system is in tact. The issue lies elsewhere

Q

We can test the language core by asking a patient to repeat a low frequency statement. If the core is damaged, alternate routes are available, but take to long. This means that the

A

Ability to repeat is compromised

19
Q

The area of damage shared by LeBourgne and LeLong is now known as

A

Broca’s Area

20
Q

Broca is the person that said that the faculty of articulated language resides in the

A

Frontal lobes of the brain

21
Q

The general name for expressive (non-fluent) aphasia

A

Broca’s Aphasia

22
Q

Patients with damage just to Broca’s area (called Little Broca’s) have an aphasia for

A

Less than 12 months

-show near 100% recovery

23
Q

More extensive frontal lobe damage (Big Broca’s) results in

A

Life long Broca’s Aphasia

-More limited recovery

24
Q

In person’s exhibiting long term Broca’s Aphasia, it is very common for them to have also suffered damage to the

25
Characterized by labored, halting speech, naming difficulties, and paraphasic errors -Comprehension is relatively well preserved
Broca's Aphasia
26
The primary auditory cortex is buried in the
Sylvian Fissure
27
The posterior 1/2 of the secondary auditory cortex is called
Wernicke's area
28
Carl Wernicke was the first to describe
Fluent Aphasia
29
Patient is fluent and highly talkative but comprehension is very poor and has difficulty following commans
Wernicke's Aphasia
30
Patient has speech that is unintelligible and is unaware of deficits
Wernicke's Aphasia
31
Disrupts communication between Wernicke's area and Broca's area -Repetition ability is compromised
Conduction aphasia
32
Wernicke's area and Broca's area are undamaged so comprehension is largely intact and patient is mostly fluent
Conduction aphasia
33
In conduction aphasia, language skills that rely on speed are
Impacted
34
Patient loses the ability to self correct sentences before uttered with
Conduction Aphasia
35
Patients make paraphasic error (substitute related wors) then go through multiple iterations until they correct the error with
Conduction Aphasia
36
Caused by damage outside of the Perisylvian Language Area -Usually involves watershed areas of the cortex
Transcortical Aphasia
37
Transcortical motor aphasia presents like
Broca's
38
Transcortical sensory aphasia presents like
Wernicke's
39
The Perisylvian core and thus repetition is spared with
Transcortical aphasia
40
Patients do not recognize the emotional content of speech with lesions to the
Right Hemisphere
41
With damage to the right hemisphere, speech is like a
Text message
42
Patients with damage to the right hemisphere have difficulty determining
When they are being lied to
43
Damage to the inferior frontal gyrus of the right hemisphere (Broca's equivalent) causes
Monotonic speech (Prosody deficits)
