Terms in this set (28)
Neurological deficits persisting longer than 24 hours
An acute neurological dysfunction of vascular origin
What is a CVA?
A clot that blocks blood flow to an area of the brain
formation of a blood clot within the brain the brain blocking blood flow to the artery
Thrombotic Stroke (Ischemic)
caused by a clot within an artery, but forms somewhere other than in the brain itself
Rupture of a small blood vessel causes bleeding to occur inside or around brain tissue
Subarachnoid hemorrhage occurs when a blood vessel just outside of the brain ruptures
Hemorrhagic Stroke: Subarachnoid
Occurs in brain. More likely to result in death or major disability that ischemic stroke or subarachnoid
Hemorrhagic Stroke: Intracerebral Hemorrhage
-Deep hypertensive intracerebral hemorrhages
-Ruptured saccular aneurysms
-Bleeding from arteriovenous malformations
-Spontaneous lobar hemorrhages
4 most common causes of Hemorrhagic stroke
Occurs as a mild, isolated, or repetitive neurological symptoms that develop suddenly and last from a few minutes to several hours, but not longer than 24 hours
*Symptoms clear up completely
Age, gender, race, ethnicity, heredity
Non-modifiable risk factors for CVA
Cigarette smoking Excessive alcohol use
illegal drug use
Management of cardiac disease, diabetes, glucose metabolism
Modifiable risk factors for CVA
dysfunction of areas of occupation, performance skills and patterns, client factors
Effects of CVA?
location of lesion and extent of damage
What does Diagnosis of CVA tell?
CT scan, MRI, PET scan, SPECT scan
How is a CVA diagnosed?
Single Photon Emission Computerized Tomography
Whats does SPECT scan stand for?
Magnetic Resonance Imaging
Whats does MRI stand for?
Positron Emission Tomography
Whats does PET scan stand for?
Whats does CT scan stand for?
Internal Carotid Artery
Middle, Anterior and Posterior Cerebral Artery
What are the 4 common CVA lesion locations?
Dominant hemisphere: usually L
- Apashia, Agraphia, Acalculia
Non-dominant: usually R
-visual perceptual dysfunction
- Constructional/dressing apraxia
Deficits from Internal Carotid Artery CVA?
Gaze preference to lesion side
dominant: usually L hemisphere
-receptive expressive aphasia if lesion occurs here
non-non-dominant: usually R
-neglect, inattention, extinction of double simultaneous stimulation fi lesion occurs here
MCA deficits for CVA?
Disinhibition and speech perseveration
Primitive reflexes (eg, grasping, sucking reflexes)
Altered mental status
Contralateral weakness (greater in legs than arms)
Contralateral cortical sensory deficits
ACA deficits for CVA?
Contralateral homonymous hemianopsia
Altered mental status
PCA deficits for CVA?
Restoration of blood flow
Hydration, IV feuds
Treatment of HTN, co-existing cardiac or other diseases
Early Medical management of CVA?
Prevention of DVT
Prevention of respiratory problems and pneumonia
Monitor BP, HR, EKG during ADL to determine cardiac response to activity
Bowel and bladder dysfunction toilet program or catheterization if necessary
Other medical management for CVA?
Denial, anger, depression, mood disorder or psychosocial dysfunction is common. Depression is the most frequently reported reaction to stroke. It develops over time and is more likely to be seen as treatment progresses.
Psychosocial adjustment to CVA?
Chart review, pt. interview, family interview, premorbid status
Observation of pt. - how do they look?
Ability to follow directions? Visual, Verbal, both?
Postural control: can maintain sitting balance?
Head and neck position/control
UE and LE function:
