DISORDERS OF LANGUAGE Flashcards
____________ refers to the production and comprehension of words whereas
_____________ refers to the articulatory and phonetic aspects of verbal expression
Language
speech
the
silent processes of thought and the formulation in our
minds of unuttered words on which thought depends
inner speech, or endophasia
by which is meant the expression of
thought by spoken or written words and the comprehension of the spoken or written words of others
External
speech, or exophasia,
Loss or impairment of the production or comprehension
of spoken or written language because of an
acquired lesion of the brain. This is the condition
called ________
aphasia or dysphasia.
A defect in articulation with intact mental functions,
and comprehension of spoken and written language
and normal syntax (grammatical construction of sentences). The terms ___________ are applied to this category of speech disorder.
dysarthria and anarthria
An alteration or loss of voice because of a disorder
of the larynx or its innervatioN
aphonia or dysphonia
The main executive, or output, region, situated at
the posterior end of the inferior frontal convolution
(Brodmann areas 44 and 45), is referred to as ______________
Broca area
and is concerned with motor aspects of speech
visually perceived words are given
expression in writing through a fourth language area, the
so-called ____________ in the posterior part of the
second frontal convolution
Exner writing area
The perisylvian language areas are also connected
with the striatum and thalamus and with corresponding
areas in the nondominant cerebral hemisphere through
the _______ and____________
corpus callosum and anterior commissure
In general, as a restatement of the Wernicke-Broca scheme, phonologic speech output difficulties are derived from _____________
semantic-comprehension difficulties are the result of ____________
and alexia and agraphia are associated with
_____________
left frontal lesions;
left temporal lesions;
inferior parietal lesions.
__________________a procedure that produces
mutism for a minute or two, followed by misnaming,
including perseveration and substitution; misreading;
and paraphasic speech);
the Wada test-
_______________ in which different words or phonemes are presented simultaneously to the two ears (yielding a right ear-left hemisphere
advantage)
dichotic listening,
the region on the superior surface of the temporal lobe
posterior to Heschl gyri and extending to the posterior
end of the sylvian fissure, is slightly larger on the left
in 65 percent of brains and larger on the right in only
11 percent
planum temporale
Left-handedness may result from disease of the left
cerebral hemisphere in early life; this probably accounts
for its higher incidence among the ________ and _______
mentally retarded and
brain injured.
T or F
findings suggest a bilateral albeit unequal-representation of language functions in non-right-handed patients.
T
the
melody of speech, its intonation, inflection, and pauses,
all of which have emotional overtones
prosody
aprosodia localization
inferior division of the right middle
cerebral artery.
In the investigation of aphasia, it is first necessary to
inquire into the patient’s __________
native language, handedness,
and previous level of literacy and education.
More often, the language most used before the onset
of the aphasia will recover first. What law of aphasia?
Prite Law
The bedside analysis of aphasic disorders that we find most useful entails the systematic testing of six aspects of language function: 1 2 3 4 5 6
conversational speech, comprehension,
repetition, reading, writing, and naming
Reading aloud single letters, words, and text
may disclose the __________
dissociative syndrome of pure word
blindness.
The patient may be unable to
repeat what is said to him, despite relatively adequate
comprehension-the hallmark of_______________
conduction aphasia
Preserved repetition is also characteristic
of _________ and occurs occasionally with
subcortical lesions
anomic aphasia
examples of this include conduction aphasia,
word deafness (auditory verbal agnosia), and word
blindness (visual verbal agnosia or alexia
disconnection
language syndromes,
patients may repeat a few stereotyped
utterances over and over again, as if compelled
to do so, a disorder referred to as ____________
monophasia (Critchley), recurring utterance (Hughlings Jackson), verbal stereotypy, or verbal automatism.
In Broca’s aphasia, speech is sparse with _________as compared with the normal 100 to 115 words
per minute
10 to 15 words per
minute
