The flashcards below were created by user jessiekate22 on FreezingBlue Flashcards. What would you like to do?


  1. What is a TACI?
    - total anterior circulation infarct
  2. 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
  3. What is a PACI?
    - partial ant circulation infarct
  4. What are the PACI symptoms?
    • - 2 out of 3 comp of tacis
    • - dysphasia either expressive or recetive
    • - typically NO drowsiness
  5. What is a POCI?
    - posterior circulation infarct
  6. 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
  7. What is a LACI?
    - lacunar infarct
  8. What are the symptoms? 
    • - discrete symptoms
    • - pure motor symptoms 
    • - pure sensory stroke
    • - ataxia hemiparesis
    • - dysarthria or clumsy hand syndrome
    • - isolate to face and hand 
  9. 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
  10. 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
  11. 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
  12. What are the symptoms a stroke pt will demonstrate if they have a posterior cerbral artery infarct?
    • Visual disturbances
    • - 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

    • Proximal occlusion
    • - contralateral hemisensory loss (loss of sensation)
    • - spontaneous pain and dysesthesia if thalamus affected (thalamic pain syndrome)
    • - contralateral severe proximal chorea (top jerky movts)
  13. 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)
  14. 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
  15. 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
  16. What happens if you have a (R) hemisphere infarct? (non dominant)
    • - controls (L) sided vol movements
    • - responsible for visuo-spatial functions
  17. How can you tell which hemisphere is dominant?
    - what hand they use
  18. What is neglect of the left side usually associated with?
    • - leison of the non dom hempisphere!
    • - there are acceptions
