Q

Why is a right hemisphere lesion more severe in terms of attention?

A

Because right directs both sides while left of directs contralateral side (right hemispace) THEREFORE one side will experience neglect

15
Q

What is the difference between SART results of patients with TBI compare to those with right hemisphere lesions?

A

Right hemisphere had slower reaction times

TBI had Quicker reactions but they were less accurate

16
Q

TBI patient’s deficit of executive control of attention makes it hard to?

A

Resist distraction

17
Q

During testing of TBI patients, what do auditory distractors do? What do visual distractors do?

A

Visual: slow reaction time

Auditory: poor performance

18
Q

Are TBI patients susceptible to internal distraction?

19
Q

How do you know if TBI patients have impairment in divided attention task?

A

Depends on the TYPE of task.

Episodic/semantic memory processing SHOWS impairments

Task that DO NOT require memory components DO NOT show impairment

20
Q

Do we know the primary deficit in TBI patients?

A

No! Depends on:

Severity, time after onset, premorbid functioning, presence of coexisting conditions (stress/depression) etc.

21
Q

T/F: dementia with Lewy bodies is the only disorder in which attention deficits are key in diagnosis according to DSM-V?

A

True!!

But attention impairments are common in neuro cognitive disorders.

22
Q

What impairments are shown early in the diagnosis of AD (Alzheimer’s)?

A

Executive control

Divided attention

23
Q

Is attention the main focus of assessment of dementia?

A

No!! But it’s helpful in obtaining diagnostic information

24
Damage of the left hemisphere causing language impairment is MAJOR in defining?
Aphasia
25
In patients with aphasia, is attention the main focus?
No but it helps with treatment
26
What does aphasia impair?
Language performance NOT underlying linguistic competency.
27
Which components of attention are commonly impaired in clients with aphasia?
Arousal, vigilance and sustained attention in linguistic AND no linguistic tasks
