does not affect the neurons
example of organic disorders
(not affect neurons)
cleft palate, polyps, nodules

motor strip area
language disorders are seen with damage to what area of brain?
how do the 2 hemispheres differ in completing a task (overall)
they differ in the type of processing needed to complete the task
relationship between education and lateral processing
less education--less lateral processing
more education--more lateral processing

the 2 kinds of CVA (cerebrovascular accident/ stroke)
lack of oxygen in CVAs cause:
what percentage of strokes/CVAs are ischemic?
the two types of ischemic CVAs
thrombotic and embolic
describe how the blood flow is blocked
most common type of CVA
tia: transient asthemic attack
warning signs of a stroke. symptoms for up to 24 hours, longer is considered a stroke
tia: transient asthemic attack results from:
artery that supplies blood the the brain
internal carotid artery
artery that supplies blood to the face
external carotid artery
common site for thrombosis
the bifurcation of the common carotid artery-at the level of the thyroid cartilage, becoming internal and external carotid arteries
circle of willis
provides blood to the cortex and subcortex at the base of the brain
what artery feeds most of the lateral surface of the brain?
middle cerebral artery
stroke in the middle cerebral artery affects:
what determines the severity of a stroke
the size and placement of the clot
artery that supplies most of the medial surface
anterior corroded artery
supplies blood to the posterior and inferior surface
posterior corroded artery
what are water shed areas?
areas around the cortex where blood flows from 2 different arteries.
somewhat immude to blockages
hemorrhage causes what percentage of CVAs/strokes?
in an hemorrhage cva, what causes the damage?
the hemorrhage pushing on the brain tissue because of the blood bursting and filling the area of the brain
hemorrhage can be associated with what 3 things that help cause?
trauma, aneurysm or hypertension.
organic disorders can be _____ or ______
developmental or acquired
acquired is considered what time frame?
after 3 years of age
