Do RHS patients usually have right side neglect?

Q

mistakes that people with left hemisphere damage make

A

they work slowly with false starts and hesitations and typically their mistakes are due to angles and lines being distorted

25
Topographic impairment
when patients have problems with extra personal space which is exhibited as difficulty following familiar routes, reading maps, giving directions
26
What do patients with topographic impairment have trouble with?
they may have difficulty recognizing visual cues or familiar landmarks
27
How can you distinguish between RHS and those with disorientation?
being able to 'talk' themselves through directions to a place
28
Geographic disorientation
recognize their surroundings but don't know the location where they are. they may believe they are in a different city
29
Do patients with RHS have problems recognizing visual stimuli if they are clear and unambiguous?
Patients with RHS generally don't have a problem recognizing.
30
When do RHS patients have problems with visual stimuli?
When they are incomplete or distorted
31
Prosopagnosia
when patients can't recognize people's faces. Can't differentiate between men and women and old faces from new faces
32
What does the right hemisphere aid in?
understanding the expression of emotion in others
33
Are RHS patients good at picking up on prosodic cues of emotions or facial expression?
No
34
RHS patients and attentional impairments
they commonly have problems maintaining and shifting attention and focusing
35
Characteristics of Diminished Speech Prosody in patients with RHS
- They lack normal intonation, monotonous - loudness variability may be lacking - reduced gestures to accompany speech - speech rate is slower - reduced emphasis and stress - they may have to explicitly state their emotions because their voice doesn't indicate emotion
36
What is the reason for the prosody problems with patients with RHS?
not clear, some think its due to an underlying affective problems and others think it is due to muscle weakness (cricothyroid muscle)
37
What are the speech characteristics of a person with RHS?
connected speech is described as confabulatory, inappropriate, excessive, rambling, irrelevant, tangential, digressive and inefficient. They tend to miss out on the main idea and focus on the details
38
How to differentiate between aphasia and RHS in regards to comprehension of narratives and conversations
patients with aphasia comprehend better in discourse because of the context, patients with RHS do not
39
How do patients with RHS deal with nonliteral expressions such as metaphors, figures of speech. etc?
they have great difficulty understanding them and may confabulate as to what they mean.
40
RHS patients and pragmatic impairments
They have issues such as turn-taking, maintaining topic and eye contact They begin and end conversations abruptly They talk too much and ignore cues from communication partner
41
Standardized Tests for Assessing Adults with RHS
- Right Hemisphere Language Battery - Mini-Inventory of Right Brain Injury - Rehabilitation Institute of Chicago Evaluation of Communicative Problems in Right Hemisphere Dysfunction (RICE)
42
Non-Standardized Tests for Assessing Adults with RHS
Some non-standardized protocols have been developed, assessing similar items as the standardized tests
43
How do you test pragmatic abilities?
typically assessed through rating scales as in the RICE and RHLB scales
44
Tests of component attentional processes
involve being presented with visual stimuli, typically flashes of light, and the pt presses a button for each occurrence. auditory sustained attention tests are done similarly
45
Test for neglect (visual attention)
Test for neglect are typically done with pen and pencil and usually cancellation tests. copying and drawing from memory. bisection tests are also used where patients are asked to divide lines into 2 equal parts.
46
tests for Selective attention
pt is presented with visual stimuli and the pt presses a button for each occurrence and has distracting and competing stimuli
47
Tests of visual organization
pt has to identify incomplete visual stimuli
48
why should clinician wait until neurological recovery is done to assess and treat indifference and denial?
to see if the denial gets resolved on its own
49
Therapy techniques for indifference and denial
use activities where patients errors can be pointed out, make a list of patient's pattern of errors and inappropriate responses and go over it. use structured activities to give opportunities to practice
50
working on Sustained Attention
use drills to improve various tasks like mazes and listening tasks
51
working on Selective Attention
Use drills where patient has to pay attention to the task, with background interference
52
working on Impulsivity
work on stop and go signals for patient to practice appropriate times to respond, can use al light or colored card and transition to gesture from clinician
53
working on impaired reasoning and problem-solving
use structured practice with tasks requiring reasoning, for example practice giving problems they have to solve as in : The boy fell off his bike and you were watching, what do you do?
54
working on reading impairments
- various reading programs are available - use colored markers to get them to attend to the left side - matching tasks where item to be matched is on left side - say " look to the left" - Instruct patients to ask themselves if something makes sense - teach to trace boundaries of an edge or page of book
55
Working on pragmatic impairments
- videotape conversation interactions for baseline to compare - discuss turn-taking and topic maintenance - view videotape and discuss - give pt strategies to use for problems - use structured practice, scripts
56
Inference failure and communication impairments
work on appreciation of humor, work on appreciation of implied meanings of metaphors, identification of verbal and pictorial absurdities, comprehension of implied information
57
Resource Allocation and RHS
pts have performance that varies depending on the processing demands then teach them to use context to facilitate performance.
58
Generalization and RHS
pts have trouble generalizing
59
how to teach them to generalize across tasks
use a source task where a patient learns a set of responses and have other similar tasks where pts generalize from source task. use as much normal environment as possible
60
Is there a lot of variability within RHS field?
yes, it a patients' abilities can change day to day
