Card Set Information
What is a TACI?
- total anterior circulation infarct
What are the TACI symptoms?
- hempiparesis and/ or hemisensory lsss
- visual spatial neglect or global aphasia
NOTE aphasia is dom hemisphere affected (if not you will have problems with spatial concepts)
- homonymous hemianopia
What is a PACI?
- partial ant circulation infarct
What are the PACI symptoms?
- 2 out of 3 comp of tacis
- dysphasia either expressive or recetive
- typically NO drowsiness
What is a POCI?
- posterior circulation infarct
What are the symptoms of a POCI?
- ipsilateral cranial nerve pasies with contralateral sensory/ motor loss
- vestibular or occular signs
- isolated cerebellar dysfunction- ataxia/ coordination
- isolated homonymous hemianopia- loss of vision of one side of both eyes
What is a LACI?
- lacunar infarct
What are the symptoms?
- discrete symptoms
- pure motor symptoms
- pure sensory stroke
- ataxia hemiparesis
- dysarthria or clumsy hand syndrome
- isolate to face and hand
What may affect the chance of survival post stroke?
- lesion size
- prolonged unconsciousness
- increased age
- severe hypertension- uncontrolable
- severe co-existing disease- heart disease
TACI and haemorrhae= bad prognosis
What are the stoke outcomes at the end of the first year?
- 30% will be deceased
- 30% will have another stroke
Of the survivors:
- 60% will require assistance for ADLs
- 5% totally dependent
- 30% of workng age are able to return to work
What are the causes of death for stoke people?
- effects of ICP esp in ICH
- infection esp aspiration pneumonia
- venous thromboembolism
1st 48hrs can prevent
What are the symptoms a stroke pt will demonstrate if they have a posterior cerbral artery infarct?
- contralateral homonymous hemianopsia (central vision is often spared)
- L hemisphere lesion alexia
- bilateral lesions
: cortical blindness (pts unaware that they cannot se- anton's syndrome)
Memory impairement if temporal lobe is affected
- contralateral hemisensory loss (loss of sensation)
- spontaneous pain and dysesthesia if thalamus affected (thalamic pain syndrome)
- contralateral severe proximal chorea (top jerky movts)
What are the symtpoms for a pt with a MCA stroke?
- Most common
- contralateral weakness- face, arm and hand
- contralateral sensory loss- face, arm, and hand
- visual field cut- damange to optic radiations
- aphasia- language disturbances- more likely with L Hemi damage esp men. Brocca's production, wernicke's comprehension
-Impaired spatial perception- more likely after R. Hemi damage, spatial neglect- dressing apraxia, constructional apraxia, topographagnosia (not knowing where u r)
What are the symtpoms for a pt with a ACA stroke?
- motor disturbance contralateral distal leg
- urinary incontinence
- speech disturbance (may be more of a motor problem)
- apraxia of left arm (sympathetic apraxia) if ant corpus callosum is affected
- if bilateral may cause apath, motor inertia, and muteness
If you have a stroke that is in the L hemisphere and this is the dominant side what effects will this have on your pt?
- eg pt right handed
- controls (R) sided voluntary movts
- responsible for verbal- analytical activities
What happens if you have a (R) hemisphere infarct? (non dominant)
- controls (L) sided vol movements
- responsible for visuo-spatial functions
How can you tell which hemisphere is dominant?
- what hand they use
What is neglect of the left side usually associated with?
- leison of the non dom hempisphere!
- there are acceptions
