Neuropsychological Rehab of Stroke Flashcards
What is stroke?
Interruption/loss of blood suply to the brain leading to cell damage
What is an ischemic stroke?
Cerebral blood flow obstruction (plaque, blood clot) that can originate at the site of occlusion (thrombus) or at a distance from the occlusion (embolus)
Most common (88% of all cases)
What is a hemorrhagic stroke
Bleeding within the brain; most commonly caused by hypertension (50%) / in younger adults most commonly due to aneurysm or arteriovenous malformation (AVM)
12% of all cases
Name me 2 types of ischemic strokes
- Left Middle Cerebral Artery Stroke
- Right Middle Cerebral Artery Stroke
What are the symptoms of Left Middle Cerebral Artery stroke?
- Right hemianopia/neglect
- Right hemiplegia/paresis
- Left right confusion
- Apraxia
- Impaired Verbal Memory
- Impaired speech-aphasia
- Slow performance
- Awareness of deficits-depression/anxiety
Symptoms of Right Middle Cerebral Artery Stroke:
- Impaired Judgement
- Impulsive/safety problems
- Left neglect
- Left Hemianopia
- Short attention span
- Denies problems, insight difficulties
- Spatial-perceptual deficits
- Visual memory difficulties
- Personality/ social cognition changes
What is the Hyper-acute stroke unit (HASU) for?
Immediate response to stroke
When can patient be transferred to local stroke unit (SU)?
When medically stable within 72h or earlier if appropriate.
What care does patient receive at the local stroke unit?
Multidisciplinary specialist rehabilitation & ongoing medical monitoring.
What happens after rehabilitation at the stroke unit?
1) discharged home with community rehabilitation and social care (as required)
2) transferred to post-acute rehab unit
3) transferred to residential or nursing home
Neuropsychological impairments of Attention and information processing speed post-stroke
1) Focused Attention
2) Divided Attention
3) Sustained Attention
4) Speed of processing information
Interventions for Attention and Speed of information processing:
1) Compensatory strategies, like time pressure management (setting timers/alarms, breaking tasks into smaller steps, using calendars, establishing routines & predictability, seeking assitance and deligating tasks)
2) Enivornmental modification (e.g. reduced distractions, have written plan, organised work area)
The cogntive strategy behind Time Pressure Management (TPM) - Main objectives
! To recognise time pressure in the task at hand
! To prevent as much time pressure as possible
! Dealing with time pressure as quicky and effectively as possible
! Urging the patient to monitor himself while using the TPM
Executive functions inpairment domains post-stroke:
- Planning and executive tasks
- Inhibition automatic impulses
- Regulating emotional responses
- Reasoning about risk and weighing up information
Which tests assess executive tasks?
Behavioural Assessment of Dysexecutive Syndrome (BADS)
Trail making tests
Delis-Kaplan Executive Functioning System (DKEFS)
Hayling & Brixton Tests
